New Jersey Shellfish growers were seeking ways for cooperatively expanding their markets. The farmers recognize that to increase their on-farm income, they need to increase the volume of what they produce, eliminate losses due to the perishable nature of food, minimize transportation and packaging expenses, and receive the highest price for what they sell. To do all this is nearly impossible for a single farm operation, but by collectively pooling their resources and efforts through the cooperative, they potentially can accomplish their goals.
Community Supported Agriculture farms, food cooperatives and chefs, all show they are eager to support the development of these shellfish cooperatives and that their customers are enthusiastic about adding local shellfish and other varieties of local seafood to their diet. Connecting to shellfish farmers expands the range of food products and meal choices for customers. Cultivating the direct-marketing channel brings the local product directly to the eater in a convenient retail or restaurant setting. These new marketing channels could potentially help farmers extract the "local and environmental sustainability premium" by assisting them to organize among themselves to lower per farm transportation and marketing costs.
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."
Dr. Semmens Starting an Experiment on Holding Channel Catfish
On Friday Team Semmens starting an experiment on holding channel catfish. This
research is part of Sujan Bhattaria's thesis research. It is also part or a Capacity
Building Grant on holding and transporting fish. KSU's Aquaculture Research
Center is seeking approaches that will support niche market prices for aquaculture
products produced by farmers in the region; approaches that will create pathways
allowing the small farmer to serve local markets with the freshest possible product.
One approach is to distribute fish live rather than processing fish centrally. Demand
for fresh local farm products is greatest in urban areas. Creating a place where
locally grown fish can be received live and processed in an urban setting creates a
pathway where the local fish farmer need not also become a processor – a critical
barrier for the small aquaculture producer. This investigation addresses the use of
small recirculating systems for holding channel catfish at two densities. Fish
shrinkage and loss, water quality parameters, several blood parameters will be
measured for unfed market size fish over a holding period of eight days.
Kentucky State University's Water Quality Class Visits The Frankfort Plant Board's Drinking Water Treatment Facility
The Water Quality Management Class (AQU 460/560) took a tour of the Frankfort Plant Board's Drinking Water Treatment Facility. Students learned the steps of the water treatment process that allow the plant operators to process around 9 million gallons of water from the Kentucky River per day. Through a series of chemical and mechanical filtration processes, this water is made into high-quality drinking water and delivered to Franklin, Woodford, Anderson, Shelby, Scott, Henry, and Spencer Counties.

Fish Morphology and Physiology Class Visit the University of Kentucky Veterinary Diagnostic Lab
Students in the Fish Morphology and Physiology class (AQU 512) visited the UK Veterinary Diagnostic Lab in Lexington. Jamie Howard, the Histology Supervisor, gave a grand tour describing each step in the process and highlighting the technology used to automate the histology lab. Sandy was kind enough to demonstrate the microtome to eleven graduate students in the aquaculture program at KSU (photo). The laboratory processes histology samples for biopsy and necropsy on a daily basis from farms across the commonwealth. The students also saw how carefully each sample is identified and tracked to see that records are always correct.

Her research will focus in the area of nutrigenomics.
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.
Mr. Alex Kramer is our newest graduate student. He is from Stuart, Virginia and would like to be called Kramer.

Kramer interested in developmental biology, and genetics. I will be working with Dr. Gomelsky on koi-goldfish hybrids. Kramer has already got his hands wet assisting Dr. Gomelsky and Dr. Novelo with their high school student in the Summer Apprenticeship Program (SAP).
Cora Teets Completes Her Practicum Research Project
Cora Teets, an undergrad student at Kentucky State University, has completed her research project entitled "The effects of excess dietary branched chain amino acids (leucine and isoleucine) on growth and health of Nile tilapia, (Oreochromis niloticus)" under the supervision of Dr. Vikas Kumar. Cora conducted an 8 week feeding trial as part of her practicum work study course and STEM student research assistant job at the Fish Nutrition lab throughout the months of March, April, and May. The results of this study will reveal the mechanism for the metabolism of excess branched chain amino acids in Nile tilapia. The data from this project will be published later this year in the Global Aquaculture Advocate magazine.
KSU Gold is a television show produced, edited and recorded by the College of Agriculture. The Host is KSU's own Lyndsey McGaha, Media Manager & Television Host for External Relations College of Agriculture, Food Science, and Sustainable Systems and Land Grant Program. Dr. Boris Gomelsky, Dr. Andrew Ray and Janelle Hager were interviewed last week on the College of Agriculture's Television Show KSU Gold. The show aired on Frankfort Plant Board's Channel 10.
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.
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."
US aquaculture producers should be able to transport live fish across state boundaries without the prospect of inadvertently triggering draconian penalties, following a ruling by a Court of Appeal last week that deems that the US Fish and Wildlife Service (FWS) does not have the authority to prohibit interstate transport of injurious wildlife.

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.
