Progress in Studies on Tilapia Genetics Capacity Building Grant

Dr. Gomelsky's research group, which includes Research Associate Dr. Noel Novelo and graduate student Jeffrey Warner, made progress in studies on the Tilapia Genetics Capacity Building Grant. Tilapia YY males and normal XX females from four different lines were stocked in recirculating water systems for spawning. Before stocking, fish were weighed and measured, and fin clips were collected for further DNA analysis. The project includes raising and thorough investigation of progenies, which will be obtained in interline tilapia crosses.

New Edition of the Guide to Using Drugs, Biologics and Other Chemicals in Aquaculture Available

A new edition of the Guide to Using Drugs, Biologics, and Other Chemicals in Aquaculture has just been released. The new edition includes updates regarding recent changes to antibiotic drug accessibility and descriptions of the most common fish diseases.

All aquaculture operations have occasional demand for drugs, biologics, and other chemicals, collectively referred to as "regulated products." The Guide was developed by the American Fisheries Society, Fish Culture Section, as a comprehensive introduction to the use of regulated products in aquaculture and a resource for fisheries professionals.

The Guide provides updated information on aquaculture drugs and contacts for providing feedback. A companion treatment calculator is available in Excel formats. These tools are indispensable for those in need of detailed information regarding the legal and judicious use of these products in aquaculture.

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.
