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.

Team Ray Stocks Shrimp in High Tunnels

The Aquaculture Production Sciences Lab recently stocked brackish-water shrimp into tanks in the high tunnels. Each high tunnel has four 3,000 gallon tanks, for a total of 16 tanks.

The shrimp were stocked at two different densities and there are tanks with and without added substrate (orange construction barrier).

This study will help to illustrate the effects of shrimp density and substrate, as well as
interactive effects of the two factors, on shrimp production and water quality. The team hopes to grow shrimp in the high tunnels during the warm months, and largemouth bass during the cool season to help Kentucky farmers optimize the use of their high tunnel greenhouses.

Welcome to Summer Apprenticeship Program (SAP) Students in Dr. Kumar's Lab

Two high school students, Jacinta Emodogo and Clamesha Alexander, from Memphis, Tennessee are taking part in the SAP (Student Apprenticeship program) at Kentucky State University.

They have joined Dr. Kumar's lab for summer research work. Students have started a research project on using insect (Black Soldier Fly Larvae) protein and oil for Tilapia feed. These larvae have been grown on by-products (brewers' grain) of brewery industry. These students have used this protein and oil to manufacture fish feed.


This project is a practical approach for bioconversion of organic waste into Tilapia feed. They will feed these insect based diets to Nile tilapia, and at the end of experiment they will get the data for growth and health related parameters. These students are working under the mentorship of Kristy Allen and Cora Teets. Both students will present this data at the end of the program.

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."

KSU Aquaculture Collaborating on Research of a New Spawning Aid (GnRH IIa)

Researchers at four institutions are collaborating in a project with the
Southern Regional Aquaculture Center to evaluate the efficiency,
reliability, safety, and mode of action of GnRH IIa in a range of species
encompassing food-fish, baitfish and ornamentals. KSU investigators
are comparing the performance of the new hormone in Largemouth
Bass with proven spawning aids like HCG and Ovaprim. In order to
obtain data from individual fish, eggs are collected in the hatchery rather
than allowing the fish to spawn naturally.

Title of the project is "Improved Reproduction in Food-fish (Catfish and
Largemouth Bass), Baitfish, and Ornamentals using a New Spawning
Aid (GnRH IIa)." This is year 1 of a two year project.

Amit Kumar Yadav Completes Masters Thesis Project

Amit Kumar Yadav has successfully completed the fish feeding trial for his Master's thesis research entitled "Essential fatty acids requirement of Largemouth Bass (Micropterus salmoides): Insight into molecular and physiological approaches". This project was funded by an Evans-Allen USDA Grant. His research was primarily focusing on estimation of optimum docosahexaenoic acid (DHA) to eicosapentaenoic acid (EPA) ratio and their requirements for juvenile Largemouth Bass. He had 12 treatments and each treatment had 3 replicates, for a total of 36 tanks. The experiment lasted for 11 weeks, and all fish were sampled on April 19-20, 2017.

At the end of the study, final body mass was measured. Blood was drawn from fish and their complete diagnostic profile and blood chemistry were analyzed by Vetscan Analyzer and Vetscan iSTAT (ABAXIS, USA) respectively. Fish were carefully dissected to isolate the intestine, muscle, and liver and were stored for determination of activities of digestive, protein metabolism and antioxidant enzymes. In addition, tissue for liver, intestine and muscle were stored for gene expression pattern and histological studies.

The data from this project will be presented by Amit Kumar Yadav at the Kentucky Academy of Science conference 2017 and Aquaculture America 2018. The results of this study will help to develop cost-effective and environmentally friendly feeds for bass.

James Schwartz Completes Research at Nofima Norway

James Schwartz, a graduate student has just returned from his trip to Norway where he has completed the second, and final objective of his Master thesis research project. James is working under the supervision of Dr. Vikas Kumar. He has conducted a comparative study of improved soybean meal, soy protein concentrate and conventional soybean meal as substitute of fish meal in Atlantic salmon (Salmo salar) diets and assessed growth, digestibility and physiological parameters at the Nofima land-based research station in Sunndalsora, Norway. Improved soybean meal (high protein, 58% and oligosaccharides, 0%) is developed by the Ohio Soybean Council and its research partners Kentucky State University and Battelle (nonprofit research organization, Ohio). Mr. Schwartz has completed a 10 week feeding trial that concluded on March 30th 2017, and the fish were weighed and sampled for histology, microarray, feces and production parameters. By collecting these samples and acquiring this data he was able to meet the goal of assessing the nutritional value of optimized soybean meal based diets for Atlantic salmon. Overall the results of this research is very useful to producers of soybean meals and the aquafeed industry.

Team Ray Stocks Shrimp in the Sustainable Aquaculture Development Lab

The Production Sciences team stocked an experiment in the Sustainable
Aquaculture Development Lab (SADL) which will evaluate the effects of
three different light levels on water quality dynamics and shrimp
production in recirculating aquaculture systems.

The LED lights are expected to increase algal abundance in the water
column which may help with reducing nitrogenous compounds such as
ammonia and nitrate. Shrimp are also able to consume algae and
therefore may benefit from supplemental nutrition provided by increased
algal abundance.

Nutrition and Production Sciences Teams Stocked Pacific White Shrimp in the KSU High Tunnels Complex

The Nutrition and Production Sciences teams stocked Pacific white shrimp for a new diet trial experiment. The experiment is designed to evaluate various dietary inclusion rates of filtered solids from last year's tilapia study at the KSU High Tunnel Complex. Last year tilapia were grown in biofloc based systems in the high tunnel tanks; some of the suspended biofloc solids were filtered from the water and sundried in shallow troughs. This diet trial is exploring a way of potentially recycling that material into diets for shrimp. The material is being evaluated as both an attractant at lower inclusion levels to help entice shrimp to consume more plant-based feed ingredients, and it is being evaluated as a potential protein source at higher inclusion levels.

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.

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.

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.
