Team Ray Stocks Larvae Shrimp in Hatchery for Future Research Projects
The Aquaculture Production Sciences (APS) team received post larvae
shrimp from a hatchery in Florida. The shrimp arrived in a next day
delivery package and they are approximately 35 days old. The APS team
will grow them in nursery tanks for about 30 additional days until the shrimp weigh roughly 1 g. At that point they will be used for experiments.
One experiment will be conducted in the Sustainable Aquaculture
Development Laboratory (SADL) and will compare different filtration types in biofloc shrimp culture systems. Another experiment will examine the use of reclaimed filtrate from greenhouse-based tilapia production systems as a feed ingredient in shrimp diets.

Kentucky State University's Aquaculture Research Center Assist with Carroll County High School's Aquaponic System
The Agriculture Teacher, Assistant Principal, and over a dozen students from the Carroll County High School visited the Aquaculture Research
Center to get a first glance of our research facilities.
The students will be constructing the system at their school and we plan to
visit them in the near future to help get their aquaponics system running. Janelle, Joe, and Ken are helping Carroll County High School set up an aquaponics system in their greenhouse. The University donated a 250 gallon tank to rear the fish, clarifier tank, biofiltration tank, and some other supplies needed to finish building their aquaponic system.
Dr. Andrew Ray Visited the Providence Montessori Middle School in Lexington, Kentucky
Dr. Andrew Ray, Assistant Professor at the Aquaculture Research Center,
visited Providence Montessori Middle School in Lexington, Kentucky. The
school is one of Dr. Ray's partners on an 1890 Capacity Building Grant.
Dr. Ray's team constructed a 20 x 48' high tunnel greenhouse at the school which contains two large fish tanks and plenty of space for growing plants. The high tunnel will be used to teach students STEM principles by growing fish and plants together. A solar panel at the tunnel powers an exhaust fan; that along with the tunnel itself will be used to teach solar energy and thermodynamic concepts.
Dr. Ray met with the Microeconomics class who had plenty of questions
about aquaculture and high tunnels; the group was investigating the plastic biomedia used in the fish tank biofilters to culture nitrifying bacteria that help to maintain appropriate water quality.
Solar Panel Arrays Are Installed At The High Tunnel Complex
Two new photovoltaic (PV) solar panel arrays were installed at the KSU High Tunnel Complex. Each is a 4.05 kW top of pole mounted array consisting of 15 panels each, for a total of 8.1 kW potential energy generation by 30 PV panels. When the sun is shining the panels generate more electricity than what is typically consumed at the High Tunnels. The extra electricity is then transferred into the overall KSU electrical system and helps to offset the energy needs of the University. This is similar to a reverse-metering system in which excess electricity is fed into the energy grid rather than being stored in batteries. Not using batteries lowers the expense and improves the environmental implications of the system.
The PV arrays are expected to generate about 9,700 kWh per year; a little less than the electrical consumption of an average Kentucky household. This project was funded by the US Department of Agriculture's National Institute for Food and Agriculture and was proposed as part of a 1890 Capacity Building Grant awarded to Dr. Andrew Ray, Assistant Professor of Aquaculture Production. The project demonstrates the intergration of renewable energy and sustainable agriculture systems by offsetting some of the electrical needs of the High Tunnel Complex where organic crops are grown alongside various aquaculture species.

James Schwartz Completes First of Two Objectives of His Masters Thesis
Mr. James Schwartz has completed the first of two objectives of his Masters thesis entitled "Comparative Study on the Effects of Different Soybean Products in Diets for Hybrid Catfish (Ictalurus punctatus x I. furcatus) and Atlantic Salmon (Salmo salar)."
He is working under the supervision of Dr. Vikas Kumar. His research work was conducted on Hybrid catfish at the Aquaculture Research Center at Kentucky State University. The 10-week feeding trial concluded in December and the fish were weighed and sampled for histology, RNA, enzyme analyses, and production parameters. By collecting these samples and aquiring this data, he was able to meet the goal of assessing the nutritional value of commercially available soybean meals (SMBs) and optimize SMB-based diets for hybrid catfish. There are significant differences between treatments, meaning that results should be useful to producers of SMBs and the aquafeed industry.
Currently, Mr. Schwartz is working on the second objective of his Masters thesis on Atlantic salmon at Nofima in Sunndalsora, Norway. Nofima is a Norwegian food research institute that operates industry-oriented research and development in aquaculture, fisheries and food.

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.
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."
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.
