Ultrasound Imaging and Histology Sampling for
Graduate Student Jasmine Iniguez's Thesis Research

Jasmine Iniguez, Jeffrey Warner, and Dr. Noel Novelo obtained ultrasound images and preserved ovarian samples for histology to complete data collection for Ms. Iniguez's thesis research. The topic of her thesis is: 'Ultrasound Imaging Diagnostics of the Reproductive Organs of Adult Nile Tilapia Oreochromis niloticus'. A total of 12 females were euthanized. Weight (g) and total length (cm) were recorded for each fish. All females were examined using the EVO II Ultrasound Scanner (E.I Medical
Imaging, Loveland, CO, USA) and ultrasound images were saved based on the fish's PIT tag (microchip) number. A cut was placed directly above the section of the skin on which the ultrasound probe was positioned. This incision was used to identify the corresponding probe placement and ultrasound penetration on the ovary. Fish were dissected, and the right ovary closest to the ultrasound probe was marked at the corresponding probe placement with a scalpel. The length (mm), weight (g), and diameter (mm) of each ovary were recorded. Ovaries were placed in 10% neutral buffered formalin for fixation for histology processing.

The ultrasound images and histology will inform ultrasound image interpretation for evaluation of ovarian reproductive condition in Nile Tilapia. An interpretation guide will be created based on ultrasound images and corresponding histology. This guide will assist in improved efficiency of broodstock management for evaluation of reproductive condition for spawning and spawning synchronization in the future.

Team Semmens's Collect Data on Channel Catfish From in Pond Raceway

Dr. Semmens and his crew collected production information from Raceway one, (RW1), one of three raceways equipped with three different devices described in the attached handout.

Raceway 1 – Grid Airlift with 1 HP regenerative blower
Raceway 2 – Aerator propeller pushing water horizontally through the raceway, variable speed operated at 0.5 and 0.75 HP
Raceway 3 – Aerator propeller pulling water through the raceway, 0.25 HP.

These Channel catfish were generated from spawning cans in the same pond as the raceways. They
collected the following information from the fish in RW1.
· Total weight
· Average weight
· Total number
· Length frequency information to determine size variability.

This information will compliment data on energy consumption, water quality, feed consumption, and
other data collected in 2021.

Floating Raceway


Raceways are commonly used to grow trout. They are concrete channels with water flowing through them. A screen on either end prevents the fish from moving up or down stream. Floating raceways apply this principle with water from a pond and may be used to grow other fish like catfish, bass, etc. Water is pushed through a channel and the inlet and outlet are screened to retain fish. Since it is not pumped or lifted above the water surface a large volume of water can be moved with a small energy investment. Water entering the raceway carries oxygen required by the fish, and water leaving the raceway removes waste. It is managed like an aquatic feed lot. Fish are stocked in the raceway, fed, and harvested when they reach a marketable size. Below is a diagram showing the elements of a floating raceway.

This project is based on the premise that floating raceways represent an opportunity for
the small farmer to practice aquaculture and place existing impoundments into profitable
production. It is based on the fact that many bodies of standing water cannot be drained, yet
are able to support a crop of fish. Floating raceways confine the fish so they can be efficiently
managed and easily harvested. Unlike a cage, relatively large quantities of fish can be grown in
a single unit. Unlike a pond with no drain, the fish can be protected from predators and some or
all the fish can be recovered at any point in time by a crew of one or two people. This feature
gives the small farmer flexibility to take advantage of niche markets and their premium prices,
or to market the entire group of fish live.
Demand for local food presents an opportunity for the small aquaculture producer. Fish
remain a novel product in this growing market. There is also demand for live fish for recreation.
Locally grown farm raised fish present an advantage if they are distributed live and processed
shortly before sale. The product can be uniformly and uniquely as fresh as possible – something
that is nearly impossible with supply chains associated with imported seafood or large-scale
production where product is transported in frozen form to grocery stores before it is purchased
by the consumer.
In this project supported by a grant from USDA/NIFA, aquaculture investigators at
Kentucky State University are collaborating with engineering investigators at the University of
Kentucky to evaluate the devices and back-up power sources to move water and improve this
technology. Alternatives to the grid airlift include an aerator motor with propeller oriented
horizontally, and a slow rotational paddlewheel.

Faculty and Staff Tour Kentucky Marine Shrimp Farms

Faul Family Riverside Farm, Henry County

Dr. Ray led a small team of Extension professionals through a tour of two Kentucky marine shrimp farms; one in Fayette County and another in Henry County. The Fayette County farm has been operating for almost four years, and is using a renovated tobacco barn in which they constructed an insulated room for growing these warmwater animals. The Henry County farm recently finished construction of a new insulated building dedicated to growing shrimp. Each farm has received a Small Farms Grant through KSU in the past. The team asked about production, possible issues that the farms experience, and gave the farmers information on ways that KSU can work with small farmers.

Visual Inspection of External Morphology and Ultrasound Imaging for Sex Identification in Nile Tilapia

The role of sex and sex identification are of vital commercial and biological significance in Nile Tilapia, Oreochromis niloticus and other Tilapia genera and species. The male and female in the Tilapia genus guard the nest and protect the fertilized eggs and larvae in the external environment (nest guarders). The male and females of Sarotherodon genus incubate the fertilized eggs and larvae in their buccal cavity, while in the Oreochromis genus only the female guards the developing embryo and fry in the buccal cavity (mouth-brooders). Sex identification is essential for effective broodstock management, reproductive conditioning, and spawning. The separation of male and females inhibits reproductive behavior and spawning and enables robust body condition and growth (with proper feeding) to build energy reserves required for spawning.

Research at Kentucky State University on genetic improvement in Nile Tilapia growth performance identified a highly productive cross (See https://doi.org/ 10.1111/jwas.12742). The cross was comprised of the Genetically Improved Farmed Tilapia (GIFT) strain as maternal brooders and YY-males as paternal brooders for production of fast growing all-male, and predominantly-male Nile Tilapia. This is important because males grow larger than females (sexual size dimorphism) and in all-male production (as opposed to mixed-sex production) all feed consumed is allocated for growth (not sexual behavior and spawning). As part of our Tilapia Extension Capacity Building Grant, KSU continues to build its genetic resources by obtaining the GIFT strain of Nile Tilapia for crossing with YY males for on farm
growth demonstrations in Kentucky. We collected and recorded data (Dr. Boris Gomelsky) on individual identification (electronic pit tagging) and visual inspection of external morphology for sex identification (Jeffrey Warner), on ultrasound imaging for sex identification (Jasmine Iniguez) for sex identification, and weight and length (Dr. Noel Novelo). The females and males were placed in separate tanks for reproductive conditioning for spawning in early 2022.

Valorizing Aquaculture Waste Into Bio-Fertilizers and Pet Feed

This is the fourth article in our series on the “circular economy.” This is part of a larger three-part series on sustainable aquaculture intensification in Europe, focused on “precision aquaculture,” “sustainable feeds” and “circular economy.” This work from the GAIN project is funded by the EU Horizon 2020 Fund. Each part in this series takes an introductory glance at the three topics, then explains how outputs from the GAIN project are contributing towards it, including the applicability to industry and governance.

Using circular economy principles, the ability to valorize aquaculture waste will be important as the industry seeks to increase and intensify production in sustainable ways. The GAIN project worked with Waister to innovate solutions that create valuable bio-fertilizers and biogas substrates and even potentially pet feed ingredients from fish side streams.

"The market is asking for an aquaponic system as ours"

“We believe that not just Luxembourg, but most of the world is both ready and asking for a system such as ours,” says Manuel Arrillaga with Fësch Haff in Luxembourg. Together with his co-founder Daryl Fuchs, he recently launched a start-up company with the aim of farming both vegetables and fish in a sustainable manner. Fuchs and Arrillage met at university, and although both have different areas of expertise - materials science versus bio-engineering - they decided to start their aquaponics journey together.

USAS Sub Chapter Students From Kentucky State University Assist Aquaculture Farmer

Kentucky State University Aquaculture students traveled to La Grange Kentucky to assist Rocky Allen with seining his aquaculture ponds. They seined about 1,500 Largemouth bass as well as other fish including Bluegill, Crappie, and other miscellaneous Sunfish. Rocky had not seined that pond for about two years and wanted an inventory of what was left in the pond. He will also use these fish to fill any orders for people inquiring about live fish. Dr. Noel Novelo, John Kelso, Uchechukwu Ohajiudu, and Michelle Loftus made the trip to La Grange to assist Mr. Allen.

Students in the Physiology and Morphology Course Conduct a Fish Transport Lab

In this lab exercise, students in Dr. Semmens's AQU 412/512 class observed the stocking methods, water quality, blood glucose, and oxygen depletion, associated with transporting fish in a hauling tank. A hauling tank with two compartments was filled with water and water depth was measured before fish were stocked. Oxygen was supplied to both compartments at the same flow rate. Also samples of water was taken to test for total ammonia nitrogen, alkalinity, pH, unionized ammonia, dissolved oxygen and temperature.

A sample of the largemouth bass were weighed to obtain an average weight and estimate the total number of fish stocked. A blood sample was taken from four fish beforestocking the hauling tank and tested to measure glucose. Fish were stocked into one compartment of the hauling tank and the water level was measured again to show the volume of fish that was loaded. Water quality parameters were checked several times over two hours, blood glucose sampled from four fish after two hours.


All data was collected, organized and shared with the class. Students had to calculate oxygen consumption, changes in water quality in both compartments, blood glucose changes in fish and consider stress on fish and mortality risk. Hands-on labs like this are vital because they prepare students for situations and problems they will encounter in the aquaculture industry.

Group Effort Supplies Local Market Demand For Freshwater Prawns In Kentucky

Dan Mooreland has been raising Freshwater Prawns (Macrobrachium rosenbergii) in Kentucky for over 20 years now. Dan's farm is tucked back on a dead-end one-lane road running along the North Fork of the Licking River in Falmouth, KY. It's a beautiful Pendleton County farm, but if you don't know how to get there – you won't find it! The rural location has caused Dan some difficulty over the years in marketing his crop of freshwater prawns, most prawn farmers market direct to the public through on-farm sales the day of harvest. Dan however typically travels to Fall Festivals, and farmers markets. He also uses Kentucky State University's mobile processing unit to clean and freeze his product for sale. Despite the disadvantage of not being in the public eye, Dan has been successful over the years and considers prawn farming profitable. Dan's prawn business profitability is at least in part due to integration of prawn nursery tanks in a converted tobacco barn – partially funded through tobacco settlement funds administered by the Kentucky Agriculture Development Board. "Baby prawns" (called post-larvae) are raised indoors in heated tanks for two months before they are large enough to be stocked into ponds in early June. This nursery phase is like planting 6" tomato plants in your garden as opposed to seeds. The nursed juveniles grow to 3,500% of their "baby" weight during the 60-day nursery period and are about 1.5" long when stocked into ponds.


Dan anticipates 75-80% survival in his nursery tanks. This requires that he initially stocks more post-larvae than he needs to stock his ponds. Some years he has had exceptional survival during the nursery phase, resulting in a surplus of juvenile shrimp ready to go in ponds. Due to the aggressive nature of prawns, if they are not stocked into ponds within two weeks of the target date, losses from cannibalism are severe. In 2020, at the start of the COVID-19 pandemic, Dan came up with a bumper crop of prawn juveniles and he had 10,000 extra juveniles. Dan contacted Kentucky State University (KSU) aquaculture staff to see if they had a need for prawn juveniles as KSU had purchased from him in previous years for research purposes. But research projects were limited at KSU due to the pandemic lock down at the time. KSU reached out to other Kentucky fish farmers through the Kentucky Aquaculture Association (KAA) and the Kentucky Department of Agriculture (KDA) to assist Dan in finding a market for his extra prawns. Subsequently, Mayer's Fish Farm – which raises largemouth bass for the liveproduct ethnic Asian markets – showed some interest in the prawns as they happened to have a couple of empty ponds that year.

KSU had previously done extensive research exploring the market potential of selling prawns as a live product in ethnic Asian markets in Chicago, New York City, and Toronto, ON and identified the value and the challenges of supplying far away markets. Appreciating that Mayer's Fish Farm had the marketing contacts to identify and supply local Asian markets, after discussions among staff and representatives from KSU, KAA and KDA, a small grant of $1,000 was awarded to Mayer's Fish Farm to purchase Dan's surplus prawn juveniles. The agreement provided that Mayer's Fish Farm would market their prawn harvest through local live haulers supplying ethnic Asian markets in Kentucky with the anticipation that additional markets would be identified which would not only benefit Dan during his prawn harvest in coming years but would also provide an incentive to Mayer's Fish Farm to invest in prawn production and diversify their aquaculture production.

The Mayer's prawn harvest in 2020 went well. They sold over 600 lbs. to a local live hauler who sold them to an Asian grocery store in Lexington. The yellow pages list seven Asian grocers in the Lexington area. Within two days of Mayer's harvest and live prawn delivery through the live hauler, Dan was contacted by a competing Asian grocery. The owners of the grocery store came to Dan's final harvest and bought over 500 lbs. They were so impressed with the product that this year they wanted to buy all of Dan's prawns. In 2021, Dan delivered virtually all his harvest from three ponds live to the Asian Market on three consecutive Fridays in September. The live hauler that Mayer's Fish Farm sold to in 2020 convinced the Mayer's to raise prawns again after insistent demand by their Asian buyer. So in 2021, while Dan supplied one Asian grocer, the Mayer's who had now invested their own money into purchasing 10,000 prawn juveniles from Dan, sold their entire harvest to the same live hauler who marketed them to another Lexington Asian grocer. The Mayer's plan to continue raising prawns as long as Dan has extras. This goes to show that success multiplies. If we work together we all rise.

Dr. Semmens Teaches Blood Sampling and Analysis

Students in this exercise sampled blood from live fish to determine values for blood parameters using a VetScan, and a glucometer. They obtained quantitative measure of blood glucose, electrolytes, blood proteins, and hematocrit from several species. Kristy Allen and Jeffrey Warner assisted with this exercise.

Each team sampled and process blood from three or more fish. Each team also practiced taking blood from a koi before trying other species. Blood samples were analyzed with the VetScan, and glucometer devices based on device availability. The VetScan device took at least 10 minutes to run a sample. Kristy Allen assisted with the Vetscan device and demonstrated how blood was to be loaded into the rotor and how to place the rotor into the device.

Students anesthetized all fish sampled with water and anesthetic (MS-222) until gill movement had slowed. The recommended rate is 150 mg/L, with 2 parts sodium bicarbonate for every gram of anesthetic added to the water. Jeffrey Warner demonstrated sampling by caudal puncture and then assisted students with the method. Blood obtained was placed directly into a heparinized tube and placed on the turntable. Blood was pipetted into a VetScan disk. Blood was also placed onto a glucose meter strip for Analysis. All results were recorded and pooled for class to review and discuss.

Holy Mackerel! Farmed & Wild Seafood Has One-Sixth The CO2 Emissions Of Beef Because Fish Do Not Require Land Or Fresh Water To Harvest

  • A new study finds farmed and wild seafood and fish have a much smaller carbon footprint than meat or dairy 
  • Carbon emissions associated with wild seafood are a sixth that of beef, a fifth of lamb, and half of cheese 
  • A single burger generates the same amount of CO2 as 9 lbs of wild sardines
  • Salmon and trout used the least land and water while silver and bighead carp had the lowest greenhouse gas levels
  • Overall, farmed seaweed and bivalves like clams and mussels have the smallest environmental impact

Increasing Production Of Aquatic Foods A Win-Win For People And Planet

September 17, 2021—Nutrition researchers have long touted the health benefits of fishsuch as salmon, cod, and herring. But the world’s waterways, from the depths of the oceans to the cutbanks of rivers to tropical reefs, offer up an incredibly diverse bounty of food sources that people around the world depend on.

To better understand the nutritional benefits of the full spectrum of aquatic foods, Harvard T.H. Chan School of Public Health’s Christopher Golden and colleagues created individual nutrient profiles for more than 3,750 species, ranging from water spinach to clams and cockles to sockeye salmon. The nutrient information is contained in the newly created Aquatic Foods Composition Database, which is open-access and available for download.

The study, published on September 15, 2021 in Nature, determined the top seven categories of nutrient-rich animal-source foods are all aquatic and include pelagic fish (sardines, herring, and other species), bivalves, and salmonids (salmon, trout, and related fish). Sustainably ramping up production and consumption of these foods through aquaculture (or farming in the ocean), supply chain improvements, and better fisheries management is critical to addressing staggering global levels of malnutrition and associated micronutrient deficiencies, Golden said.

Fish Morphology and Physiology Class Utilize Ultrasound as Part of Their Class Lab

Graduate students participated in interactive lecture and laboratory sessions on ultrasound imaging in aquaculture and fisheries as part of the Fish Morphology and Physiology class taught by Dr. Kenneth Semmens. The information and discussion session was led by Dr. Noel Novelo, ultrasound imaging specialist in the KSU Aquaculture Program, and graduate student Jasmine Iniguez, whose thesis is on developing fish handling and ultrasound imaging procedures for reproductive assessment of Nile Tilapia. Students obtained hands-on experience in ultrasound imaging of different fish species including Channel Catfish, Nile Tilapia, and Ornamental (Koi) Common Carp.

They obtained experience in positioning the probe and handling the fish. They identified different parts of the ultrasound image displayed (position of the probe, the dorsal and ventral aspect of the fish, and the near and far field-of-view). And they obtained cross-sectional images on three planes (transverse, frontal, and sagittal planes).

Ultrasound imaging technology plays an important role in increasing our knowledge and efficiency in management of our cultured and wild fish, and other aquatic organisms. It is safe, and it is particularly appropriate for this reason to use with valuable fish (such as endangered fish or hatchery brooders) for minimal stress and rapid, on the spot assessments.

Safe fish handling procedures is a priority at all times, and it should be integral in sonography procedures. Ultrasound diagnostics in aquaculture and fisheries reproduction is often used to identify sex of fish that would otherwise be undetectable based on their external appearance, and to assess the reproductive condition (ovary and testis development). The information obtained is used to make decisions in aquaculture and wildlife fish hatcheries to increase reproduction efficiency, and to improve management of wildlife fisheries and survival of endangered species.

Blue Food May Be A Green Way To Feed More People

A new review of the aquatic foods sector, or “blue” foods, shows how fisheries and aquaculture can play a greater role in delivering nutrition and improving food systems around the world.

Five peer-reviewed papers in the journal Nature highlight the opportunities to leverage the vast diversity of blue foods in the coming decades to address malnutrition, lower the environmental footprint of the food system, and provide livelihoods.

People around the world eat more than 2,500 species or species groups of fish, shellfish, aquatic plants, and algae. Together, these foods provide livelihoods and incomes for more than 100 million and sustenance for one billion.

What is the healthiest fish to eat? The best choices for you and the planet.

(CNN)We're all trying to make healthier choices, but when it comes to fish, is one type truly better than another? Nutritionally, there's no wrong choice when it comes to seafood as a food group.

"As an animal source, it has one of the lowest amounts of saturated fat in relation to protein," said Lourdes Castro, registered dietitian nutritionist and director of the NYU Food Lab. In addition to being a lean protein, seafood is high in D and B vitamins and minerals like iron, potassium and calcium.
Most crucially, seafood is high in omega-3 fatty acids, which are essential to the cellular makeup of our bodies and can help with our cardiovascular health and immune systems. Because the body can't produce its own omega-3s, all our intake must come from the food we eat.
"Our diets typically don't contain a lot of omega-3s," said Mary Ellen Camire, professor of food science and human nutrition at the University of Maine. Eating seafood twice a week is one surefire way to increase our intake of these fundamental fatty acids.

Fish Morphology & Physiology Students Grade Catfish

There is no substitute for hands-on experience. And last week students in the Aquaculture Fish Morphology and Physiology class acquired some hands-on experience grading Channel catfish with the guidance of their professor PhD Ken Semmens. Many fish are sold by size or grade. Grading fish can increase the market value by supplying the grades or sizes of fish desired by customers. For example, smaller minnows are worth more per pound than larger fish. Most of the fish sold for bait, stocking, or food fish are sold by size or grade. Fish grow at different rates, resulting in of various fish sizes at harvest. Grading can remove the fish not in the size range that processors and live markets are willing to accept.

Also, some fish species are cannibalistic and must be regularly graded to maintain survival rates. Largemouth bass, striped bass and their hybrids, and more are cannibalistic fish. The grading frequency will depend on the growth rate and their size. The first few months post hatch are usually the most important for minimizing losses due to cannibalism.

Floating Raceway Design For Small Farms

Dr. Semmens crew is developing a floating raceway design for small farms and have recently scaled up a suspended design that can be constructed at modest cost on the small farm. It was stocked with 5000 feed trained largemouth bass fingerlings produced by students and staff at the Aquaculture Research Center to obtain preliminary data. We are growing catfish in our other raceways, but bass represent a higher value fish that has not been evaluated in this format. We expect there will be advantages with feeding, and management of the bass, but cannibalism and rapid fish growth are a concern.

The bass were stocked into a raceway with 9 cubic meters of growing space. The raceway frame is 32 feet long and the raceway itself is about Four feet deep and 20’ long with about eight inches of freeboard. The bass stocked in the raceway will be grown out as food fish in other raceways next year. We will assess performance of the bass in the raceway this fall.

WHOI, WWF Team Up On Seaweed Farming Research

A leading U.S. ocean science research institution and a prominent international environmental NGO are teaming up to examine sugar kelp farming and how new strains could help the growing seaweed farming industry.

Over the next two and a half years, the Massachusetts-based Woods Hole Oceanographic Institution (WHOI) will conduct two breeding and harvesting seasons, starting this year, on commercial partners’ farms in the Northeast United States. By identifying different strains, they will match specific traits to meet targeted needs, such as taste and texture.

Partners will take part in breeding and nursery practices with the goal of amplifying and testing new kelp varieties jointly developed by WHOI and the University of Connecticut with funding from the U.S. Department of Energy. This research will be funded in part by World Wildlife Fund (WWF) and the Bezos Earth Fund.

Team Ray Kale Winterbor F1 Aquaponics Trial

Dr. Ray’s team harvested a 54-day brackish-water aquaponics trial investigating potential differences between coupled and decoupled systems when growing Kale with Pacific white shrimp. This initial trial reinforced kale’s potential use in brackish water aquaponics, in addition to identifying key issues not found in freshwater. Overall, kale in coupled systems out-performed kale in decoupled systems, particularly in metrics important to farmers (survival, harvest weight). Nitrate reduction was 18.4% in coupled systems and 5.8% in decoupled systems, an important finding that may help shrimp farmers increase long term water use and reduce waste discharge.

Nine Things You Probably Did Not Know About Aquaculture

Many aquaculture producers in the United States don’t raise fish, despite the industry’s popular image of fish farming. In fact, oysters were the most commercially valuable domestic farmed marine species in recent years. In 2017, oyster farmers harvested 36 million pounds valued at $186 million. And clams ranked number two in production value in 2012–2017. Other top U.S. marine aquaculture products include mussels, shrimps, and salmon.  

In recent years, a growing number of entrepreneurs are also turning to kelp to supply sustainable seafood and coastal jobs.

USAS Sub Chapter Students From KSU Clean Up at the Yuko-en on the Elkhorn

Kentucky State University Aquaculture Graduate Students in the USAS Sub Chapter and the Secretary for the Yuko-En on the Elkhorn Board, Arlene Wilson took time on a Saturday to clean up around the Japanese Koi Garden.

The Yuko-en on the Elkhorn is a four season, five 1/2 acre garden, open daily from dawn to dusk and is free to the public. This garden became the Official Kentucky Japan Friendship Garden by proclamation by the Legislature of the Commonwealth of Kentucky.

The goal was to clean up the grounds of the Koi garden, as well as help with the removal of excess plants and algae inside the pond. Kentucky State University Aquaculture Research Center previously donated over 50 koi to assist in cleaning the duckweed in the pond. The volunteers from KSU were Dr. Noel Novelo,, Michelle Loftus, Jasmine Iniguez, Shrijan Bajracharya, James Brown, and Andrew Lohman and his wife.

Aquaculture and the Growth of Land-Based Fisheries

What is something that humans have been doing for almost as long as people have been putting food on the table? While hunting comes to mind, certainly, there is something else that isn’t nearly as intensive and benefits from economies of scale. It is, of course, fishing. Whether it’s used as a metaphor for the value of education, a religious story illustrating compassion, or just something you do to “get away from it all,” fishing is ingrained in our psyche. Indeed, the global fisheries market was $130.0B in 2018 and is expected to grow 19.46% to $155.3B by 2023.

The why behind that increase is the expected growth in fish consumption, which recently reached a record 20.5 kilogram per capita per year and is expected to grow further in the decade ahead to 21.5 kilograms per capita, driving technological advancements in what is known as aquaculture.

Team Ray's Kale Winterbor F1 Aquaponics Trial

Dr. Andrew Ray's lab stocked an aquaponics trial with Pacific white shrimp (Litopenaeus vannamei) and Kale Winterbor F1 hybrid at 15 ppt. salinity using a homemade salt mix. The trial will compare coupled and decoupled systems, with three replicates of each system. Six 1.8 m³ aquaponic systems were stocked at a rate of 300 shrimp per cubic meter (125 shrimp per system), and with 66 kale plants per system.

Kale seeds were germinated in fresh water and acclimated to salt over a 15-day period prior to stocking. The trial will run for six weeks, during which time plant metrics will be measured weekly and water quality measured thrice weekly to monitor nutrient levels. Decoupled systems will be coupled periodically based on a system's nutrient levels and plant performance. This trial will determine Kale Winterbor's performance in brackish water aquaponics systems, and highlight any challenges to shrimp and/or plant production. Results will help facilitate improved protocols in brackish water aquaponics using non-traditional species.

Climate Change is Draining The World's Lakes of Oxygen

Oxygen levels in the world’s lakes are declining because of climate change, according to new research published last week in the journal Nature. Global heating is increasing water temperatures, which reduces the amount of oxygen water can hold. Less oxygen may cause problems for fish and other freshwater wildlife, reports Damian Carrington for the Guardian.

The study analyzed changes in water temperature, clarity and oxygen content for 393 lakes located in temperate climates in North America, South America, Asia and Europe over time. For some lakes, the data stretched all the way back to 1941, but the majority of the records began in the 1980s, reports Kirsti Marohn for Minnesota Public Radio (MPR).

Jasmine Iniguez is Using Ultrasound Imaging as an Assistive Reproduction Technology for Her Thesis Research on Nile Tilapia, Oreochromis niloticus

Jasmine Iniguez has been collecting data for the first study of her thesis research directed by Dr. Noel Novelo, her major professor. Adult Nile tilapia were placed in three fish positions (ventral recumbency, lateral recumbency, and dorsal recumbency) with the probe positioned on the transverse plane at five frequencies (6, 8, 10, 12 and 14 MHz) at three external anatomical landmarks. The ultrasound equipment used was the EVO II Ultrasound Scanner equipped with a multiple frequency waterproof probe that produces linear array images. Once ultrasound images were saved, fish were euthanized and placed into an ice slurry for a couple hours during rigor mortis. Fish were then placed in the freezer, and the frozen fish were cut on the transverse plane at each landmark with a bandsaw.

The purpose of this study is to develop fish handling and ultrasound scanning procedures for viewing the internal anatomy and reproductive organs in Nile Tilapia. Ultrasonography plays an important role in aquaculture because it can be used as a noninvasive means of assessing reproductive conditions in fish.

Team Ray's Kale Toscano Nitrite Uptake Trial

Dr. Andrew Ray's lab harvested a Toscano Kale trial, investigating the plant's potential to tolerate and uptake nitrite in brackish water conditions. Previous trials on the plant's salt-tolerance yielded 100% survival and promising results for use in brackish water aquaponics.

The current trial examined 10 and 20 ppt. salinities, including treatments with added nitrite at each salinity. Although survival was 100% in the current trial, there were detrimental effects observed on plant growth in treatments with added nitrite. Interveinal Chlorosis, a yellowing of the tissue between the veins of a leaf due to the decline of chlorophyll production, was significant on some plants at 10 ppt.; however, other plants showed no adverse effects with added nitrite. In addition, contorted growth and partial leaf necrosis was observed at 20 ppt. with added nitrite; however, the necrosis may have been enhanced due to salt spray on the foliage.

Toscano Kale shows impressive tolerance to brackish water conditions, and future trials will include aquaponics with reused shrimp water and Pacific white shrimp.

Toscano Kale, also known as Dinosaur Kale, is nutritious, tasty and easy to prepare because both the rib and leaf can be eaten, cooked or raw. It's an excellent source of vitamins A, C, and K and has over 50 percent of the recommended daily allowances for each.

Singapore’s urban farmers seek high-tech solutions to turn waste into resources

SINGAPORE — Thousands of wriggling larvae won’t deter this self-declared “urban farmer.”

Chua Kai-Ning is one of the founders of Singapore’s first urban insect farm, Insectta — a high-tech farm that rears the black soldier fly to help turn food waste into biomaterials for industrial use.

“The black soldier fly is a way to contribute to what we call the circular economy, where we produce things without anything going to waste,” said the 26-year-old, who has a background in English linguistics. Some in Singapore are turning to urban farming in this land-scarce city, as they look for high-tech ways to turn waste into useful resources.

Chua is one of them.

Andrew Lohman Harvests Research Project

In total 240 plants were harvested. Representative samples for plant height, individual plant weight, and chlorophyll analysis were taken from 80 plants. Surface area of the roots and shoots were recorded as well as the wet and dry weights of the shoots. Andrew is waiting on the results of the nutrient analysis of the shoots. Throughout the study information on the representative plant heights were collected twice a week.

He collected the total fish biomass removed from the tanks and the amount of feed fed over the course of the study. Individual weights and lengths on 4 fish per tank were also taken.

All the lights used were standardised to 200 PAR. The lights used 87 to 125 Watts, which is a much tighter spread of energy consumption than his previous study. The lowest lights consumed 1.23 kWh per day and the highest lights consumed 1.74 kWh per day. Regarding the light spectrum, the
Red:Blue ratio varied between lights with the controls being 6.6, and with the three experimental lights being 1.3-2.5 R:B ratio. The price of the individual lights varied from $100 to $390 for the experimental ones, and the control was $1600.

Andrew still needs to run statistics for the data collected and is waiting to receive nutrient analysis on the shoots and water samples sent out. Andrews Major Professor is Jim Tidwell, Professor and Chair and,KSU Distinguished Professor at the Division of Aquaculture.

Here Are the Benefits of Farm-Raised vs Wild-Caught Salmon

You know salmon is good for you. But when it comes time to choose at the grocery store, it can be overwhelming. There are a variety of types to choose from, and the advantages and disadvantages are often hotly debated. How can you tell which is better for your health (and the health of the planet)? Should you eat farmed-raised salmon or wild-caught? All food production requires resources that put pressure on the environment, explains Richard Waite, a senior research associate for the food program at World Research Institute. To keep up with the increased interest in seafood while also being efficient with resources, fish farming is a necessity.

New Sustainable Advances Help Reimagine Fish Farming

Fish farms haven't always had the best reputation, but that seems to be changing fast. Many scientists and chefs believe fish farms may be the future of food due to a combination of factors, including overfishing in our oceans and a global population that keeps rising.

Dr. Kevan Main leads Mote Aquaculture Research Park in Sarasota, Florida. The park is 20 miles away from the ocean but has seawater running through it constantly. The water is recycled and reused 24 hours a day. 

The fish are quarantined when they first arrive. "That is when we first bring them in from the wild. We have to keep them by themselves and have to check them and make sure they're healthy and put them through some treatment," Main told CBS News' Jeff Glor.

At the farm, Main is raising Red Drum, Snook and Almaco Jack. Almaco Jack are also known as Longfin Yellowtail, have very sharp teeth and are also very adaptable. Main originally found the fish about 100 miles out in the Gulf of Mexico. They've been raised to be perfect, healthy large breeders.

The Salmon You Buy In The Future May Be Farmed On Land

The fish in question are Atlantic salmon, which are far more typically found in the cold waters of Norway's fjords or Scotland's lochs.

As the species is not native to Florida, and would be unable to cope with the state's tropical heat, the water tanks are kept well chilled, and housed in a vast, air-conditioned and heavily insulated warehouse-like building.

The facility, called the Bluehouse, opened its first phase last year, and intends to be the world's largest land-based fish farm.

Targeting an initial production of 9,500 metric tonnes of fish per year, its owner - Atlantic Sapphire - plans to increase that to 222,000 tonnes by 2031, enough to provide 41% of current US annual salmon consumption, or a billion meals.

Kentucky State University Received $740,000 Grant Funding For Aquaponics Research

The Kentucky State University School of Aquaculture and Aquatic Sciences, in the College of Agriculture, Community, and the Sciences, received approval of funding on a grant proposal titled,

"Improving Phosphorus Recovery in Aquaponic Systems through Environmental Manipulation of the Plant Rhizosphere Microbiota."

The project will run for four years with total funding of $740,000. The highly competitive grant program is funded by the U.S. Department of Agriculture (USDA) National Institute of Food and Agriculture (NIFA), Agriculture and Food Research Initiative (AFRI), and Agricultural Microbiome in Plant Systems and Natural Resources.

"With the increasing interest in aquaponics in Kentucky, I am thrilled that USDA is supporting this research project, which will greatly benefit our stakeholders in this state and beyond," Dr. Kirk Pomper, dean of the College of Agriculture, Community, and the Sciences and director of the Land Grant Program, said. Dr. Jim Tidwell is the project investigator and Janelle Hager is the lead author on the proposal, with the assistance of Leigh Anne Bright. The project will also involve close cooperation with Dr. Carlos Rodrigue-Lopez and Dr. Mark Coyne of the University of Kentucky.

"Agriculture is increasingly a technology driven enterprise. We see several examples of that right now in Kentucky," Tidwell, professor and chair of the School of Aquaculture and Aquatic Sciences, said. "As we try to feed more people with limited resources and to bring the means of production closer to the consumer, controlled environment systems like aquaponics will become even more important in the future. The funding in this grant will allow us to better understand the bacterial transformations essential in these simple, yet complex systems, allowing even greater resource efficiencies as we move forward."

Fishing is a wonderful warm-weather pastime many of us enjoy. At the extension office, we often receive calls in the spring and fall from landowners on how to properly stock recreational ponds with fish.

Pond owners can call farm supply stores during the spring and fall to find out when their live fish trucks may arrive. Fish are typically transported during cool weather to reduce handling stress. The fish are typically small and can be hauled short distances in large, water filled containers.

Kentucky Department of Fish and Wildlife Resources no longer stocks recreational ponds, but the department recommends the following fish species to establish a balanced fish population that will provide good pond fishing in about two years' time. Bluegill (not hybrid bluegill) and largemouth bass form a predator-prey relationship where the prolific spawning of bluegill provide enough food to support a largemouth bass population. Largemouth bass consume some of the bluegill and control their overpopulation. Two years after you stock a pond, you should have largemouth bass at least a foot long and bluegill at least 6 inches in length. You can catch these fish provided they are stocked and harvested in the proper numbers.

Dr. Semmens And Team Begin Moving Fish For 2021 Research Projects

Preparations are underway to grow channel catfish in floating raceways with three different configurations in 2021. The first device is a grid style airlift, the most common way to aerate and push water through a floating raceway. A second device using a propeller device pushing water horizontally through the raceway will have oxygen sensors and controls to turn on an aerator as needed. The third device is a smaller solar powered propeller unit with controls to turn on an aerator as
needed.

Brood catfish, paddlefish, grass carp, koi carp, bass, and bluegill populate the raceways pond. Cans placed in the pond in 2019 yielded catfish spawn which was hatched and grown to large stocker size in three 0.1 acre ponds the Aquaculture Research Center and stocked in the raceways at the KSU Farm
late in 2020.

This years performance of the three systems will be assessed throughout the growing season. Approximately 4,000 fish, weighing about 0.25 lb each will be stocked in each raceway system for
grow-out.

Shrijan Bajracharya Completes His Research Project

Graduate Research Assistant Shrijan Bajracharya's research project on Pacific White Shrimp lasted 90 days. He did encounter issues with water quality during the study, other than that the overall research went well.

At harvest, Shrijan removed and collected samples of the solids as well as shrimp samples from each tanks. He dried the solids in a oven and grinded them into a powdered and the samples were stored in the freezer for further analysis. The six shrimp samples were dissected and the hepatopancreas was removed, forzen in liquid Nitrogen and then stored at -80°C for analysis at a later date. He will be checking the digestive activity of lipase, amylase, and trypsin.

Shrijan's research has concluded but he still has plenty of work ahead. He has to analyse samples as well as run statics and write his thesis.

Kentucky State University Aquaculture Research Center Donates Shrimp to
Spark Community Café

Associate Professor Dr Andrew Ray donated over 100 pounds of salt water shrimp to Spark Community Café on March 11, 2021. As a result of Dr Ray's research at the Aquaculture Research Center there are times that extra shrimp are available. Part of Dr Ray's USDA 1890 Capacity Building Grant research project is to donate extra shrimp to Spark Community café.

On March 27, 2019 Spark Community Café opened a pay what you can, pay it forward restaurant. Their goal is to provide good food with dignity for all participants in a community space that educates, entertains, and accepts all who walk through their doors. They provide farm-to-table meals to their guest regardless of their ability to pay.

The Spark Community Café philosophy is "If your pockets are full pay it forward. If your pockets are light pay what you can, if your pockets are empty volunteer your time with us."

The shrimp will be used as part of Spark's food programs in an attempt to get food to parts of the underserved community. Kyle Fannin, Executive Director of Spark Community Café said, "Our goal in the beginning was for 20 percent of the food to go to the food insecured of Woodford County. During the pandemic 2/3 of the food went out to the food insecured." Spark will be serving the shrimp in every way you can imagine over the next few weeks.

Chef Isaiah Screetch and Cook Anna Collins were preparing shrimp Po Boy sandwiches in the kitchen when we arrived and said the Shrimp Po Boys were already a big hit. Anna Collins said, "We spent hours processing the shrimp and her hands were sore." Chef Isaiah was interested in tilapia and other Kentucky grown aquaculture products in the future.

Farming Fish In Freshwater Is More Affordable And Sustainable Than In The Ocean

A tidal wave of interest is building in farming the seas. It's part of a global rush to exploit oceanic resources that's been dubbed the "blue acceleration." Optimistic projections say that smart mariculture—farming at sea—could increase ocean fish and shellfish production by 21 million to 44 million metric tons by 2050, a 36%-74% jump from current yields. Other estimates suggest that an ocean  area the size of Lake Michigan might produce the same amount of seafood as all of the world's wild-caught fisheries combined.

Why That Salmon On Your Plate Might Have Been A Vegetarian

Twenty years ago, as farmed salmon and shrimp started spreading in supermarket freezers, came an influential scientific paper that warned of an environmental mess: Fish farms were gobbling up wild fish stocks, spreading disease and causing marine pollution.

This week, some of the same scientists who published that report issued a new paper concluding that fish farming, in many parts of the world, at least, is a whole lot better. The most significant improvement, they said, was that farmed fish were not being fed as much wild fish. They were being fed more plants, like soy.

In short, the paper found, farmed fish like salmon and trout had become mostly vegetarians.

Surprising Side Effects of Eating Fish, According to Science

From salmon to sardines, Atlantic herring to Atlantic mackerel, there are multiple health benefits of eating fish. Packed with protein, vitamins, and minerals, fish is also a low-calorie, zero-carb food filled with polyunsaturated fatty acids, a type of healthy fat that falls under the category of essential nutrients.

It's no wonder fish consumption has been on the rise. According to the latest statistics from the Fisheries of the United States report, which was compiled by the U.S. Department of Commerce, Americans enjoyed an average of 16.1 pounds of seafood per person in 2018.

Could land-based seafood production help save our oceans?

Land-based aquaculture can sound like a mirage — shrimp farms in the desert, salmon swimming “upstream” in an alpine village tank, tilapia swishing over the plains. And for a long time, ample production of sea delicacies in recirculating aquaculture systems (RAS) has been more dream than reality. Yet the technology and its innovators have steadily gained momentum and may finally be hitting their tipping point into next-big-thing territory.

The allure of fish grown on land is easy to understand: Like all aquaculture, it reduces demand for wild fish, but unlike sea-based cages, closed-loop RAS farms run no risk of fish escaping to dilute the native gene pool, spread diseases, or discharge waste and antibiotics into the wild. RAS farmers have near full control over growing conditions, so they can optimize for growth and quality. And with its amenability to unlikely locations, RAS can sit near major consumer markets, providing fresh local seafood even when the shore is hundreds of miles away.

"Evaluating a low-cost salt mixture in brackish water intensive shrimp (litopenaeus vannamei) production systems"

Marine shrimp grow well in tanks and recirculating aquaculture systems, making them a great candidate for providing fresh healthy seafood to consumers at inland locations. However, commercially available sea salts can be a substantial expense when growing shrimp inland.

To help overcome this, the Ray Lab conducted an experiment comparing a much less expensive home-made salt mixture to a commercial product. They used five different ratios of low-cost/commercial salt mixtures, including a 100% low-cost treatment.

The experiment resulted in no significant differences in shrimp production using any of the salt ratios, and the cost of salt per kg of shrimp produced was 57% lower using a 100% low-cost salt compared to the commercial product.

Mark Jonannemann Works on No Media Denitrification Research

The idea of no media denitrification is like that of biofloc, which uses suspended particles of organic matter to provide substrate for beneficial nitrifying bacteria in the water column. However, for denitrification no air is delivered to the tank, creating conditions conducive for facultative anaerobes to reduce nitrate and nitrite into dinitrogen gas.

In this study the effects of four different carbon/nitrogen ratios (5:1, 3:1, 1:1,and no added carbon) are being examined on denitrification of wastewater without a bioreactor from a pacific white leg shrimp (Litopenaeus vannamei) crop growout. Carbon in the form of 190 proof ethanol (donated from our partner The Jim Beam Company) is added daily to maintain the proper C/N ratio per tank based on the water quality results from the end of the previous week. This is done daily along with parameters including temperature, Dissolved Oxygen (DO), pH, salinity and Oxidation-Reduction Potential, (ORP); while water quality consisting of Total Suspended Solids/Volatile Suspended Solids (TSS/VSS), turbidity, (total ammonia nitrogen) (TAN), nitrite, nitrate, phosphate, alkalinity, and sulfide are analyzed once per week.

The purpose of this study is to gain a better understanding of no media denitrification. This information will be used to help local producers reduce costs by reusing water for more crops.

Could Astronauts Rear Fish On The Moon?

The seabass eggs, all 200 of them, were settled in their module and ready to go. The ground crew had counted the eggs carefully, checked each for an embryo, and sealed them tightly within a curved dish filled precisely to the brim with seawater.

The countdown, and then—ignition! For two full minutes, the precious eggs suffered a riotous shaking as the rocket’s engines exploded to life, followed by another eight minutes of heightened juddering as they ascended to the heavens. These embryonic fish were on their way to low Earth orbit. Next stop: the moon.

Michelle Loftus Takes Part in Hybrid Stripped Bass Digestibility Trial

Graduate Research Assistant Michelle Loftus was busy this week working with Hybrid stripped bass, M. chrysops × M. saxatilis at the Aquaculture Research Center's Nutrition Lab. The Hybrid striped bass is a cross of the striped bass (Morone saxatilis) and the white bass (M. chrysops). About ten million pounds of Hybrid stripped bass are produced in the United States annually. The fish are used both as a food fish and a gamefish.

Dr. Rossi's team is working with hybrid striped bass conducting a digestibility trial. The project has been running for about a week now. The trial will most likely run for about 8 weeks.

2022 Census of Agriculture: Your Voice, Your Future, Your Opportunity

The 2022 Census of Agriculture is right around the corner and USDA NASS is making every effort to count all aquaculture producers in the United States.

If you produce any aquaculture products and want to make sure that you are counted in the 2022 Census of Agriculture and the 2023 Census of Aquaculture, please sign up your operation using this online form:

https://www.agcounts.usda.gov/cgi-bin/counts/

Once you have signed up, you might receive a short survey in the next two years to further categorize your operation. But most likely, you will not receive a survey until the 2022 Census of Agriculture in January or February, 2023.

When signing up, please keep these items in mind to better understand how USDA NASS counts aquaculture production:

To be counted as an aquaculture farm, some form of intervention in the rearing process, such as seeding, stocking, feeding, or protection from predators, must be done by the producer.
Aquaculture is defined as the farming of aquatic organisms, including baitfish, crustaceans, food fish, mollusks, ornamental fish, sport or game fish, algae and sea vegetables, and other aquaculture products.

Fish, shellfish, and other aquatic products which are caught or harvested by the public from non-controlled waters or beds without any intervention, or input costs, are considered wild caught and are NOT included in the USDA NASS count of aquaculture farms.
Remember, participating in the 2022 Census of Agriculture and the 2023 Census of Aquaculture is Your Voice, Your Future, and Your Opportunity. To learn more about the Census of Agriculture and Aquaculture, visit www.agcensus.usda.gov.

All information you provide will be held confidential under penalty of federal law. There is NO sharing of individual farm financial data with other federal agencies other than the final compiled reports that are publicly available. Since NASS surveys are conducted for statistical purposes only, individual reports are protected by law, even from other governmental agencies. Please read and share the NASS Confidentiality Pledge: https://www.nass.usda.gov/About_NASS/Confidentiality_Pledge/index.php.

If you have any questions, contact Tony Dorn at tony.dorn@usda.gov or (202) 690-3223.

On behalf of the National Agricultural Statistics Service and USDA, thank you for your timely response and dedication to U.S. agriculture.

New Publication on the Evaluation of Growth, Sex (Male Proportion; Sexual Dimorphism) and Color Segregation

Dr. Novelo, Dr. Gomelsky, Shawn Coyle and Alex Kramer have published an article "Evaluation of growth, sex (male proportion; sexual dimorphism) and color segregation in four cross combinations of
different strains of XX female and YY male Nile Tilapia" in the Journal of the World Aquaculture Society.

Abstract
Four cross combinations of different YY male and female Nile Tilapia, Oreochromis niloticus, strains were evaluated for growth, sex, and color segregation. Red color parental strains included blotched phenotypes. The Genetically Improved Farmed Tilapia (GIFT) was the only dark (wild-type) color parental strain. Fish of the same age and cross were stocked in three replicate tanks for four crosses in one recirculating system for 167 days. Data recorded included feed consumed, body weight, total length, color, sex, and fillet weight. YY males crossed with GIFT females (Cross 2) exhibited superior growth that was significantly different (p < .05) to other three crosses. Male proportions were 79–100%. Only YY males crossed with the LSA female strain (Cross 4) yielded 100% males, but, Cross 4's productivity was inferior to that of Cross 2. Body weight advantage of males over females was 28.7–84.2%. Color segregation indicated that red color trait in Nile Tilapia is autosomal dominant, and black patch coverage was variable. This study showed that different parental strain combinations clearly impact productivity traits, and that YY male technology combined with crossbreeding provide the opportunity for genetic improvement and development of commercially beneficial superior traits in Nile Tilapia.

Team Ray Publishes Research in Aquaculture Engineering

The Dr. Andrew Ray's lab recently published a new research paper in the peer-reviewed journal Aquacultural Engineering. The paper is titled "The effects of artificial substrate and stocking density on Pacific white shrimp (Litopenaeus vannamei) performance and water quality dynamics in high tunnel-based biofloc systems" and is the first aquaculture study completed in the KSU Organic High Tunnel facility. This study found that increasing density can greatly increase total shrimp harvest weight with minimal impacts on individual performance, decreased nitrate accumulation in the systems due to algal activity, and the feasibility of shrimp production in high tunnels in temperate climates without the use of supplemental heat sources (electric or gas).

Dr. Boris Gomelsky Publishes Video On Koi Breeding

 

 

Dr. Boris Gomelsky and KSU Aquaculture graduate students spawned koi in the hatchery this Spring. Video was recorded, edited and posted onto YouTube. This video demonstrates the process of koi artificial breeding and includes stripping of eggs and sperm from koi broodstock, and artificial fertilization of eggs. In order to remove adhesiveness, after fertilization eggs are placed in McDonald incubation jars where they are vigorously moved in water/milk suspension by air bubbles for 50-60 minutes. Then air flow is substituted with water flow for further incubation of eggs.
