Team Gomelsky Move Koi and Koi x Goldfish Hybrids To The Aquaculture Production And Technologies Laboratory

Koi and koi x goldfish hybrids were netted from the outdoor tanks located at the Aquaculture Research Center this week and transported to the Aquaculture Production and Technology Laboratory

Dr. Gomelsky's team is investigating inheritance and expression of some dominant koi color mutations in koi x goldfish hybrids. The purpose of this study is to development color variations of hybrids which could be used for weed controls in ponds and recreational water bodies.

One-hundred of the Koi will be used by Western Hills High School located in Franklin County. The koi were picked up by a teacher, J.R. Zinner who has been working with Ken Thompson. Ken has been collaborating with this particular school during the 2019-20 academic school year (STEM Education USDA Capacity Building Grant project). Western Hills is one of eight schools participating in the project this year.

Students are engaged in hands-on aquaponics project-based investigation (APBI) environments designed to develop a depth of learning the standard-based ecological concepts based on current Next Generations Science Standards (NGSS). Students will also gain a deeper conceptual understanding of the aquaculture content material.

Identification of Biological Structures Using Ultrasound Imaging

The objective of this exercise is to provide a hands-on experience for each student to identify biological structures in live fish and interpret images obtained with ultrasound devices. The lab began with a presentation by Dr. Novelo on the principles of ultrasound and the two devices to be used in the lab. Following the presentation, the class moved to the hatchery and set up to examine Channel catfish. Students were divided into two groups corresponding to the two ultrasound units. Each student had the opportunity to operate the probe and the controls of each ultrasound machine. Dr. Noel demonstrated each unit as needed.

Ultrasound images were obtained with two ultrasound machine systems. The first images were taken by an older ultrasound unit (model: Aloka SSD-500V; Aloka Co., Ltd., Tokyo, Japan) with a single
frequency 5 MHz probe (model: UST-5820-5; Aloka Co., Ltd., Tokyo, Japan). The second ultrasound system used was a more advanced ultrasound unit (model: Ibex® EVO™ Ultrasound; E.I. Medical
Imaging®, Loveland, Colorado, USA), with a multiple frequency probe (model L10X; E.I. Medical Imaging®, Loveland, Colorado, USA) and a goggle-style headset (model: InSite®2 Video Headset; E.I. Medical Imaging®, Loveland, Colorado, USA) that is very useful in bright sunlight and heavy reflective environments that may cause difficulty in viewing images on the display screen on the machine.

Examples of internal anatomy viewed:
· Skin
· Muscles - segmentation of muscles by the horizontal septum and vertical septum.
· Vertebrae (and other bone structures)
· Urinary Bladder
· Buccal cavity
· Brain
· Heart

Dr. Andrew Ray Presents in Brazil

Dr. Ray traveled to Fortaleza, Brazil to give a research seminar to students, staff, and faculty at the LABOMAR Research Facilities, part of the Federal University of Ceara. He then traveled to Natal, Brazil to present the first half of an all-day long workshop on intensive shrimp farming. The workshop attracted over 175 participants who were all highly engaged and gave highly positive reviews of the material. Dr. Ray also traveled across Northern Brazil, visiting a variety of shrimp farmers, all of which are intensifying their production and interested in learning about the research being conducted at KSU.


Dr. Semmens's Fish Morphology and Physiology Class Toured Veterinary Diagnostic Laboratory

On August 27, 2019 the Fish Morphology and Physiology class toured the Veterinary Diagnostic Laboratory, Department of Veterinary Science, College of Agriculture, Food & the Environment, College of Public Health at the University of Kentucky. Diane Murphy gave the complete tour of an impressive facility. The histology lab was of particular interest. She demonstrated the use of
the microtome as she described the process of preparing a slide and featured each of the various automated devices.

This laboratory is a fine example of something our students cannot find on campus. It was very good for the students to hear of the way they identify each sample and recheck to see that records are in order in every step of the process. Perhaps some of the students will make better use of histology in their research.


Leo Fleckenstein Defends His Thesis

Mr. Fleckenstein successfully defended his thesis research on Wednesday, August 21, 2019. His committee members were Dr. Ray, Dr. Rossi and Dr. Tidwell. His research was "The Effects of Substrate and Stocking Density on Pacific White Shrimp (Litopenaeus vannamei) Performance and Water Quality Dynamics in High Tunnel-Based Biofloc System."

Scientific Breakthrough at the Florida Aquarium could save America's 'Great Barrier Reef'

(CNN)The Florida Aquarium in Tampa, Florida, says they've made scientific history as a group of coral has successfully reproduced two days in a row for the first time in a lab setting.

The milestone could have broad implications for "America's Barrier Reef," which is the third largest coral reef in the world and is found just off the coast of the Florida Keys.

The successful result is part of what the aquarium calls "Project Coral" -- a program designed in part with the goal of ultimately repopulating the Florida Reef Tract. The project works in partnership with London's Horniman Museum and Gardens to create coral spawn, or large egg deposits, in a lab.

Saltwater Shrimp From A Landlocked State? How This Kentucky Farm Is Making It Happen.

At first glance, the Faul Family Riverside Farm in Sulphur, Kentucky, resembles any other, with long stretches of grass where cows, chicken and pigs graze. But beyond its barn and the idyllic country farmhouse is a building with two above-ground swimming pools, each holding about 5,000 saltwater shrimp.

Kentucky is a landlocked state far from any saltwater, yet the Faul farm is one of three that raise shrimp in the state — the others in Lexington and a small operation in Lawrenceburg.

The farm, co-managed by father-son pair Andre Faul Sr. and Andre Faul Jr., practices non-conventional farming, with shrimp being just one of its newest ventures. And even though it's a new part of their small 100-acre farm, they have already seen tons of success, with regular customers at both the La Grange and Bardstown Road farmers' markets and two Louisville restaurants, Harvest and Buck's Restaurant, that consistently buy and serve their product.

Kentucky State University and the University of Kentucky Collaborate on a USDA/NIFA Grant

Dr. Ken Semmens is working on a USDA/NIFA grant collaborating with engineering investigators at the University of Kentucky to evaluate and back-up power sources to move water through an in-pond raceway. The research will be conducted at the Kentucky State University Farm on Mills Lane. They are researching three different methods to move water through the raceways. One method uses a one horsepower blower that uses air to move water. There is also a 3/4 horsepower motor and propeller in a separate raceway. And also a slow rotation paddlewheel that uses 0.07 horsepower to move water will be evaluated.

The research will also evaluate power consumption, water flow, and back-up power supplies. This research will be James Brown's, from Kentucky State University, and Bo Smith from the University of Kentucky thesis research projects.

Dr. Dasgupta and Richard Bryant Publish Marketing Research in the Journal of the NACAA

Restaurants are increasingly featuring locally grown food. While locally grown vegetables and meat seem to be popular, locally grown fish could be another product option. This paper presents data related to the marketing of locally grown fish to independent restaurants in Kentucky and Ohio. The results show that restaurants are interested in several types of locally-grown fish; however, their top choices were trout, hybrid striped bass, and catfish. Using the restaurants' stated willingness to pay as a guide, the sales of whole trout and catfish fillets could be profitable for local, small-scale farmers.

It's Time To Be Honest About Seafood

Demand for seafood is increasing across the globe, and the United States is no exception. Aquaculture, or aquatic farming, is increasingly meeting this demand and now supplies just over 50 percent of all seafood globally. In fact, it has been one of the world’s fastest growing food sectors for years.

The U.S. is the largest importer of seafood in the world, and some of Americans’ favorites—including shrimp, salmon and tilapia—are predominantly farmed these days. Yet, we contribute less than 1 percentof the world’s total aquaculture production. This means we rely heavily on other countries to satisfy our appetites for seafood.

The World's Rivers are Contaminated with Antibiotics, New Study Shows - CNN

(CNN)The world's rivers are widely contaminated with antibiotics, according to a new global study, the first of its kind. 

Researchers from the University of York in the UK analyzed samples from rivers in 72 countries and found that antibiotics were present in 65% of them.
Dangerous levels of contamination were most frequently found in Asia and Africa, the team said, with sites in Bangladesh, Kenya, Ghana, Pakistan and Nigeria exceeding safe levels by the greatest degree. 
The worst case was found at a site in Bangladesh, where concentrations of the drug Metronidazole -- which is used to treat bacterial infections, including skin and mouth infections -- exceeded safe levels by up to 300 times. 
Safe levels can range from 20,000 to 32,000 nanograms per liter (ng/l), depending on the antibiotic, according to new guidelines established by the AMR Industry Alliance,a coalition of biotech, diagnostics and pharmaceutical companiesset up to provide sustainable solutions to curb antimicrobial resistance.

Dr. James Tidwell Addresses the United Nations Association

Dr. James Tidwell addresses the United Nations Association on Monday, May 20, 2019 at the Paul Sawyier Public Library. His talk will focus attention on the important role of aquaculture in providing future food supplies. The Frankfort Chapter of the United Nations Association of the USA will sponsor a program on Monday, May 20, at the Paul Sawyier Public Library's Community Room at 6:30 p.m. in Frankfort, Kentucky.

Dr. Jim Tidwell, Chair of the School of Aquaculture and Aquatic Sciences at Kentucky State University, will discuss " Aquaculture: Feeding the Future." The program is free, and the public is invited to attend.

"Given that most wild fish populations have been fully exploited or even depleted, while human populations continue to grow, aquaculture is becoming increasingly important in providing healthy protein to an ever-increasing world population," said Dr. Jim Tidwell. "Additionally, fish are inherently more efficient than land-animals, allowing better utilization of finite resources.

Dr. Andrew Ray and Mr. Leo Fleckenstein Help Co-Author Publication

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.

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 ..."

The title of the July 9, 2018 FAO News Article is "Is the planet approaching "peak fish"? Not so fast, study says; Significant production increases foreseen over coming decade - Sector faces major challenges"

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. 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.
