2018 International Indoor Shrimp Farming Workshop at Kentucky State University

KSU's Aquaculture Research Center hosted the 2018 International Indoor Shrimp Farming Workshop at the Harold R. Benson Research and Demonstration Farm. The workshop was a great success with 216 participants attending the event. Some participants traveled very long distances to attend the workshop including locations like Germany, Canada, Slovakia, and Mexico. The United States was also well represented with people attending from 28 states, including Hawaii and California. There were 27 participants from Kentucky that attended the workshop. Most participants were from the shrimp aquaculture industry.

Presenters included government officials, industry leaders, and academic scholars. A mixture of
presentations, tours, and engaging discussions helped to bring to light some of the most important topics facing this rapidly growing industry.

Team Ray and other faculty and staff from the College of Agriculture, Communities and the Environment worked hard the make the two-day event a success.

This paper examined two methods of stunning in three model crustaceans. Stunning is used to reduce sensory perception prior to euthanizing animals. This is especially important in places such as Europe where some markets require that animals are electrocuted prior to slaughter to prevent pain in the animal. However, this paper found that electrocution only paralyzed the three species (blue crab, red swamp crayfish, and Pacific white shrimp); the heart rate was decreased temporarily, then increased but was irregular. Immersion in an ice slurry below 4 degrees C resulted in sedation within seconds for shrimp and crayfish, but not crabs. The ice slurry stopped the shrimp heart the quickest, indicating that an ice slurry may be the most humane method of stunning these animals.

How To Get America On The Mediterranean Diet

In 1953, not long before President Dwight Eisenhower suffered a heart attack in office, the social scientist Leland Allbaugh published “Crete: A Case Study of an Underdeveloped Area.” The landmark analysis of the eating patterns of an isolated Greek population strongly suggested that a calorie-limited diet high in fresh fruits and vegetables, whole grains, and olive oil and low in animal protein, particularly red meat, could lower the risk of heart attacks and strokes, decrease chronic disease and extend life.

Medical research over the last half-century has largely borne out this initial finding. Weight-loss fads and eating trends come and go, but the so-called Mediterranean diet has stood fast. “Among all diets,” Dr. Walter Willett of Harvard’s T.H. Chan School of Public Health concluded in an email, “the traditional Mediterranean diet is most strongly supported for delivering long term health and wellbeing.”

Aquaponic "Build Your Own System" Workshop

Kentucky State University's Aquaculture Research Center conducted a "Build Your Own
Aquaponics System Workshop," on Saturday, July 21, 2018. Participants had the opportunity to learn the basics of system design, how to build their own systems, and acquired the tools to maintain their own backyard aquaponic system.

Many of the items used for their systems are affordable and can be easily acquired. The Intermediate Bulk Containers or IBCs are lightweight, durable, corrosion resistant and can be purchased at most farm stores. The bottom portion of the IBC's were cut off and used to hold the grow media for plants and the top portion will be utilized to rear fish in the aquaponic system.

At the end of the day, participants got to take their systems home. Staff at the Aquaculture Research Center will be checking in on the success of the participants and how well they did with their backyard aquaponic systems.

Team Ray Publishes Two Part Series in the Journal of Aquaculture Engineering

Tom Tierney and Leo Fleckenstein published a two part series in the Journal of Aquacultual Engineering. Both papers looked at the effect of various RAS filtration systems on water quality and animal production metrics. Tom's paper examined those effects on shrimp and included a survey of stable isotope dynamics among the animals, while Leo's paper examined the impacts of the filtration techniques on juvenile tilapia. Both papers explore ways that farmers can produce fresh seafood year-round without much water use, thereby helping to facilitate sustainable food production.

The State of World Fisheries and Aquaculture 2018

UN Food and Agriculture Organization (FAO)

'The State of World Fisheries and Aquaculture 2018' is the title of a report released by the UN Food and Agriculture Organization (FAO) which found that "... global fish production will continue to expand over the next decade even though the amount of fish being captured in the wild has leveled off and aquaculture's previously explosive growth is now slowing ... [The] report projects that by 2030 combined production from capture fisheries and aquaculture will grow to 201 million tonnes ... That's an 18 percent increase over the current production level of 171 million tonnes ... In 2016, production from aquaculture reached 80 million tonnes, ... providing 53 percent of all fish consumed by humans as food ... Some 59.9 percent of the major commercial fish species that FAO monitors are now being fished at biologically sustainable levels, while 33.1 percent are being fished at biologically unsustainable levels ... The other 7 percent are underfished ..."

Fishy Study Links Seafood To Prevention Of Parkinson's

A new study from Sweden suggests the link between consumption of fish and better long-term neurological health could involve the protein Parvalbumin.

The protein, found in great quantities in several different fish species, has been shown to help prevent the formation of certain protein structures closely associated with Parkinson's disease.

One of the hallmarks of Parkinson's disease is amyloid formation of alpha-synuclein. The team at Chalmers University of Technology have discovered that parvalbumin can form amyloid structures that bind together with the alpha-synuclein protein. It effectively 'scavenges' the alpha-synuclein proteins, using them for its own purposes, thus preventing them from forming their own potentially harmful amyloids later on.

"Parvalbumin collects up the 'Parkinson's protein' and actually prevents it from aggregating, simply by aggregating itself first," explains Pernilla Wittung-Stafshede, Professor and Head of the Chemical Biology division at Chalmers, and lead author on the study published in Nature.

With the parvalbumin protein so highly abundant in certain fish species, increasing the amount of fish in our diet might be a simple way to fight off Parkinson's disease. Herring, cod, carp, and redfish, including sockeye salmon and red snapper, have particularly high levels of parvalbumin, but it is common in many other fish species too. The levels of parvalbumin can also vary greatly throughout the year.

"Fish is normally a lot more nutritious at the end of the summer, because of increased metabolic activity. Levels of parvalbumin are much higher in fish after they have had a lot of sun, so it could be worthwhile increasing consumption during autumn," says Nathalie Scheers, Assistant Professor in the Department of Biology and Biological Engineering, and researcher on the study.

Other neurodegenerative diseases, including Alzheimer's, ALS and Huntington's disease, are also caused by certain amyloid structures interfering in the brain. The team plans research this topic further, to see if the discovery relating to Parkinson's disease could have implications for other neurodegenerative disorders as well.

Alexander Kramer Starts Research Thesis Project

Alexander Kramer's research thesis project is on the evaluation of the reproductive ability of triploid koi x goldfish hybrids. This year the reproduction of triploid females having two haploid genomes of goldfish and one haploid genome of koi was investigated.

During spawning, these triploid females were crossed with males of koi and goldfish. Obtained larvae were stocked for raising in outdoor round tanks.

In three to four months the ploidy of juveniles from these progenies will be determined by flow cytometric analysis of DNA content in the erythrocytes. Based on these data, some conclusion on ploidy of eggs produced by triploid females will be made.

Amit Sharma Starts Thesis Research Project

Amit Sharma is currently working on his thesis research titled "Evaluation of Spawning
Aids for Induced Spawning of Largemouth Bass (Micropterus salmoides)". In this study
he is comparing GnRHIIa with HCG and GnRHIIa+Domperidone combination in induced
ovulation and spermiation of female and male largemouth bass respectively. He is
studying ovulation related parameters in female largemouth bass and investigating effects of different hormone injection in sperm quality (sperm density and sperm motility) of male largemouth bass.

It is part of a project with the Southern
Regional Aquaculture Center (SRAC) titled "Improved Reproduction in Foodfish (Catfish
and Largemouth bass), Baitfish, and Ornamentals using a New Spawning Aid (GnRH
IIa)".The project involves collaborative work of four institutions on studying efficacy,
reliability and safety of GnRH IIa in various species.

The work at Kentucky State
University features evaluation of this spawning aid for induced spawning of Largemouth
Bass. The safety and performance information from the study will help forming FDA
compliant trials for approval of an INAD (Investigational New Animal Drug).

Kasandra Miller Harvests Thesis Research Study

Kasondra Miller is continuing to conduct her thesis research on the dietary phosphorus requirement of Largemouth bass fed plant based diets. Plant based diets result in antinutritional factors. Phytic acid; found in corn, wheat, and soybeans; impacts the digestion and absorption of phosphorus. The aim of adding additional phosphorus in plant based diets is to supplement to account for the unavailable phosphorus bound up in the phytic acid.

Kasondra and her colleagues in the nutrition department harvested and processed the Largemouth bass for plasma, molecular analysis, organ indices, proximate analysis, and carcass mineral composition.

Farming Fish Saves Land: Study

Journal reference: Proceedings of the National Academy of Sciences

More information: Halley E. Froehlich el al., "Comparative terrestrial feed and land use of an aquaculture-dominant world," PNAS (2018). www.pnas.org/cgi/doi/10.1073/pnas.1801692115

April 30, 2018, University of California - Santa Barbara

To satisfy the protein demands of an anticipated nearly 10 billion people by 2050, the United Nations' Food and Agriculture Organization (FAO) and researchers around the world estimate current animal production will need to grow by an average of 52 percent. Meeting this need without pushing the environment to the brink will be critical.

New evidence shows seafood from aquatic farming—aquaculture—can help feed the future global population while substantially reducing one of the biggest environmental impacts of meat production—land use—without requiring people to entirely abandon meat as a food source.

A new study from UC Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS) found that the amount of cropland required to support future protein needs with more farmed aquatic animals would be significantly smaller than if terrestrial livestock production met those needs. This research is the first land-use analysis of future food systems to focus on aquaculture—the world's fastest-growing food sector—and helps reveal its potential role in conservation and food security. The findings appear in the Proceedings of the National Academy of Sciences.

KSU Graduate Students Spawn Paddlefish

Aquaculture Graduate Students in the AQU 527/528 Fish Reproduction and Spawning
Techniques class and Lab will be spawning fish for the next few weeks. This week they have
been working with Paddlefish. Students used gill nets to capture fish at the Aquaculture
Research Center, moved them to the Aquaculture Hatchery and injected the fish with
hormones to speed up the reproduction process. This hands on work is part of the students
class. Two females, three males were chosen to spawn.

Students handle the fish and make direct observations that complement printed materials,
videos, and other class materials. The class is taught jointly by Dr. Gomelsky and Dr.
Semmens. Dr. Steve Mims, who taught at the Aquaculture Research Center before retiring,
also assisted with spawning this week.

KSU is known for our work with paddlefish so it is a bit of a tradition as well. The students
certainly enjoy it and are not likely to get this experience at other locations.

The hatchery lab course covers induced spawning of paddlefish, largemouth bass, koi, and koi
x goldfish hybrids. Dr Gomelsky covers tilapia and there are field trips – for example, the Kentucky Department of Fish & Wildlife Resources Peter W. Pfeffer Fish Hatchery to observe spawning of sauger.

World's Largest Aquaponics Operation Opens in American Heartland

There might be plenty of fish in the sea. Now, more than 1,000 miles from the Atlantic Ocean, there are plenty of Atlantic salmon—120,000 pounds' worth—in the Town of Northfield, Wisconsin.

Superior Fresh, LLC, opened in late August thanks to a university-private industry collaboration and is expected to employ up to 50 people. The business reports it is the largest aquaponics facility in the world and the first indoor recirculating aquaculture system (RAS) in Wisconsin raising Atlantic salmon.

The 40,000-square-foot fish-rearing facility is using the same water to raise the salmon, as well as rainbow trout, which nurtures eight types of greens in a RAS setup that is also known as aquaponics. All the products will feed consumers hungry for fresh, locally produced goods. Superior Fresh is, said COO Brandon Gottsacker, "Based on the prospect that we can change the world."

The Surprising Benefit of Eating Fish


Salmon fillet

Ordering off the seafood menu may help ease the aches and pains of rheumatoid arthritis (RA), according to a new study in Arthritis Care & Research. People with RA who ate fish at least twice a week reported less joint swelling and tenderness than those who rarely or never did—and the findings suggest that the more fish they ate, the less active their disease.

The study involved 176 people with RA who answered questions about their diet over the past year. Specifically, the authors looked at responses to questions about how often people ate tuna, salmon, sardines and other fish prepared raw, broiled, steamed or baked.

They did not look at how often people ate fried fish, shellfish or fish in mixed dishes (like shrimp stir-fry, for example), because these meals tend to be lower in omega-3 fatty acids—a type of fat with anti-inflammatory properties. Previous studies have shown that taking fish-oil supplements (which are rich in omega-3s) may benefit people with RA, but this is among the first studies to look at the consumption of actual fish.

Aquaculture is drawing entrepreneurs and investors, in an overfished world with a growing appetite for the healthy protein.

Farmed or wild? Local or imported? Organic? Or some certification you've never heard of?

Anyone who has tried to be an eco-conscious seafood consumer—or seen headlines about plummeting wild fish stocks or antibiotic-laden seafood from farms in China—has faced these questions.

There are many more. Take farms, whether inland or in the ocean. So much depends on the particular operation. Are antibiotics used to fight disease in overcrowded pens? What's the feed made from, and is too much provided? How much waste do the fish create? Are the currents strong enough to disperse all of that? What is the ocean floor like? Are the fish native?

"With fish, people come in and debate," said TJ Tate, director of the Sustainable Seafood Program at the National Aquarium in Baltimore. "Consumers want to see a tag, a label, a box, something they can feel confident about, and grab it and go."

"A lot of labels are private or secretive or changing or flexible," said Marianne Cufone, executive director of the Recirculating Farms Coalition. Some are more respected than others, and it's hard for the average consumer to know the difference. While Canada and the EU have organic seafood standards, the U.S. does not.

Now, entrepreneurs, investors, and some environmentalists are beginning to coalesce around aquaculture as a potential long-term solution to the depletion of the oceans and the world's increasing appetite for this healthy protein. A 2016 report from the United Nations found that 31.4% percent of the world's stocks were overfished and another 58.1% fully fished. Meanwhile, aquaculture surpassed wild-caught fish as a source of seafood for human consumption in 2014. Many see it as the next frontier in sustainable food production.

"We're eating more seafood globally, which is a good thing because it's healthy, but we're taking more than the ocean can naturally replenish," said Amy Novogratz, managing partner of Aqua-Spark, a Netherlands-based investment fund focused on sustainable aquaculture businesses. "Aquaculture is known a little bit for its bad reputation, and some of it is deserved," she said, referring to issues like China's use of antibiotics and fish feed made from wild-caught species. "But it's a young enough industry that you can go in and rebuild it a little, so as it grows, it grows more sustainably."

The Future Of Food Is Wet And Salty

Forbes recently published an article titled, The Future Of Food Is Wet And Salty, detailing aquaculture as food.

Aquaculture is an umbrella term that describes seafood farming in all its iterations, including growing saltwater fish and shellfish in the ocean, and freshwater fish in recirculating systems on land. Aquaculture isn't new–some methods, like traditional Hawaiian fishponds and oyster farming as practiced in Ancient Rome, are age-old practices. But much of the rapidly expanding aquaculture industry today is thriving on new technologies and techniques. And this industry–especially the ocean-based iterations of it–represents the future of food.

Dr. Andrew Ray Publishes Article in Ohio State University Newsletter

Dr. Andrew Ray, Assistant Professor of Aquaculture Production, published an article in the December issue of Buckeye Aquafarming, an extension publication from Ohio State University. The article is titled "The basics of biofloc aquaculture systems," and details some of the opportunities and issues surrounding the intensive aquaculture systems that Dr. Ray works with at KSU.

Biofloc systems get their name from small "floc" particles suspended in the water column which are largely composed of microorganisms. These microbes help to maintain proper water quality and provide supplemental nutrition to animals such as shrimp, thereby recycling nutrients and lowering the animal feed conversion rate.

Americans Are Eating More Fish, But Still Not Enough

This week is all about turkey. But year round, Americans are making room on their plates for more fish and other seafood.

We ate an average of 15.5 pounds of it in 2015, continuing a three-year rise, says a recent report from the National Oceanic and Atmospheric Administration (NOAA).

But here's the catch: That's roughly one 4-ounce serving each week, or half the 8 ounces recommended for most adults in U.S. dietary guidelines. The American Heart Association also urges adults to eat two fish meals a week.

Constructing Fish Tanks in High Tunnel Greenhouses


This video was shot at the Kentucky State University High Tunnel Complex. High tunnels are relatively simple greenhouse structures commonly used to extend the growing season of crops. In this video Dr. Andrew Ray describes some large fish tanks that have been constructed with wooden frames and rubber liners. The fish tanks are being used to grow tilapia, with the goal of getting market-sized fish in one growing season in Kentucky. Time-lapse and underwater video footage help to illustrate Dr. Ray's points.


Dr. Sid Dasgupta, Richard Bryant, and Alejandro Velasquez recently published an article in World Aquaculture Magazine titled, "Local Food Markets For Catfish In Kentucky."

Team Gomelsky Publishes Two Aquaculture Articles

Dr. Gomelsky and his team recently published two articles in new issues of North American Journal of Aquaculture. The first article describes ploidy variability and viability of fish obtained from triploid koi females. It is typically considered that triploid fish are sterile. However, triploid
koi females, which were obtained at the Aquaculture Research Center at Kentucky State University, developed large ovaries and appeared to be fertile. The data presented in the article shows that fish obtained by crossing triploid koi females with normal diploid koi males are aneuploids and
have intermediate ploidy between diploid (2n) to triploid (3n) level. This indicates that triploid females produce aneuploid eggs with unbalanced chromosome numbers.

The second article describes inheritance of red eyes in koi. Red eyes is a trait typical for albino fish or other animals. However, data presented in this article shows that trait "red eyes" in koi is under control by not albino but by another demelanization mutation. In experimental progenies red-eyed fish with black (melanin) pigmentation on body were identified. Also, crossing of red-eyed koi with wild-type colored common carp resulted in appearance of fish with black eyes and light body color. These studies were supported by USDA Evans Allen and State's Program of Distinction funds.

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.

Scale-Transparency and Red-Eye Mutations in Koi


Dr. Boris Gomelsky, KSU Aquaculture Professor, describes two mutations in koi and demonstrates mutant fish from experimental progenies.

Growing Marine Shrimp in a Biofloc System


This video was shot during a harvest of the indoor marine shrimp production system at Kentucky State University's Aquaculture Research Center. Dr. Andrew Ray describes some of the benefits and concepts behind biofloc-based aquaculture. The video serves as an introduction to this relatively new and exciting topic which can be used to grow marine shrimp in practically any building, allowing fresh, whole, jumbo shrimp to be grown near and sold to a variety of inland markets.
