AgDiscovery Students Visit The Aquaculture Research Center

The Kentucky State University AgDiscovery (AgD) Program is a two-week, residential program targeting diverse students from limited-resource communities interested in careers in animal science and veterinary medicine.


The USDA's Animal and Plant Health Inspection Service (APHIS) partners with various Universities and Colleges to deliver the AgDiscovery program at locations throughout the country. Each University's program focuses on a specific area of interest to our Nation's agriculture such as:

• Plant Health
• Entomology
• Veterinary Science
• Animal Care Biotechnology
• Agribusiness


While at the Aquaculture Research Center the high school students learned how to net, measure, and weigh fish. They also had the opportunity to dissect fish and identify internal and external fish anatomy. They also toured the Genetics Lab, Food Prep-room, and Water Quality Lab.

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.

Dr. Ray's Research Team Publishes Research:

"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.
