RAS spreadsheet available
Raising yellow perch in a recirculating system may or may not be profitable. Here is a tool that may predict the outcome before you spend a lot of time and money. The University of Wisconsin Extension has recently completed a study on yellow perch raised in a RAS. Extension people have also come up with an EXCEL spreadsheet where you can play with the numbers. Here is the URL in which you can find the link to the spreadsheet. https://campus.uwsp.edu/sites/cols-ap/nadf/All%20NADF%20Documents/Yellow_perch_RAS_production.pdf

State not sure about pushing aquaculture
The Michigan Department of Agriculture is telling Michigan residents who are developing home-grown seafood programs to slow down.
WKAR radio reports the department is not necessarily opposed to aquaculture, it just wants the industry to grow slowly. The radio station reports that there are 100 members in the newly christened Michigan Aquaculture Association.
But that delay is frustrating to some who see the industry poised to explode as it has in Ohio, where in the past 12 years the number of registered fish farms went from 35 to 270.
“Without having the capacity, without having the capability, without having a guaranteed market, we’d be criticized for making large investment an industry that’s in the start up phase,” [Secretary of Agriculture Keith Creagh] says.
Meanwhile, one shrimp farmer based in Meridian Township, just east of Lansing, says he is seriously considering a move to Ohio. There, he says, the state will assist him in pushing his product. Russ Allen runs the shrimpery, which he says is ready to break open the Michigan market, but can’t get capital to make it happen.
“Here in the United States, we don’t have any programs that are really development-oriented, to develop new businesses and new technologies, with long-term low interest loans or grant programs–that kind of thing that it takes to get it started,” he says.
So why is Allen convinced the market will open? He points to the local food movement, a declining fisheries industry worldwide and the easy access to high protein foods to feed the shrimp in Michigan — soybeans.

Soy in alternative feed
Soy Meal Replacement Continued in Fish Diet Research
Illinois soybean farmers continue to step up partnerships with the state’s aquaculture industry through checkoff-funded market development. Aquaculture, as a segment of Illinois animal agriculture, offers promising soy demand potential.
ISA and the Southern Illinois University Fisheries and Illinois Aquaculture Center held a meeting recently for industry experts to talk with current and prospective fish farmers. The group discussed activities to support the industry and promote Illinois and U.S. aquaculture expansion.
“The relationship of the soybean industry to aquaculture is direct and simple: as we develop higher levels of soybean meal inclusion in fish diets, we can anticipate that as much as half of fish feeds will be soy products,” says Tony Schuur, ISA aquaculture strategy program contractor. “When we consider typical fish feed conversion ratios of about two to one, that means that every pound of fish produced might soon represent an additional pound of soy consumption.”
More than 60 participants attended the meeting in late February. Schuur and Paul Hitchens, SIUC aquaculture specialist, focused on development of cage culture production of hybrid striped bass in the numerous and expansive strip mine lakes across southern Illinois.
“Strip mine lakes represent tens of thousands of acres that with an estimated sustainable yield of 5,000 pounds per acre per year might support an industry of as much as 50 million pounds of fish worth $200 million dollars,” says Schuur. “The essential cage culture technology and production system is a viable production method that can easily be replicated. It is not capital intensive, and most farmers can pay back their entire investment in as little as one year of production.”
James Garvey, Jesse Trushenski and Brian Small from the center discussed the unique role of the SIUC program, as well as described research in fish nutrition. Studies include performance of hybrid striped bass fed a diet where most conventional animal proteins and oils are replaced with soy products, along with research efforts to raise shovel-nose sturgeon on soy-based feeds for caviar and meat markets. The center is conducting similar research with rainbow trout, tilapia, white seabass and cobia to grow demand for soy for a range of freshwater and marine fish.

Bridgeport Aquaculture School
School (of fish) in session

BRIDGEPORT — Two dozen, two-year-old male tilapia swim in a tank the size of a large round bathtub in the expansive Hatchery Lab of the newly expanded Bridgeport Regional Vocational Aquaculture School.
By mid-October, the fish, which have already enjoyed a lifespan longer than most of their kind, will be one of the products sold when the school opens its own fish market.
“It all builds on our theme of kids interacting with the community,” said School Director John Curtis, during a tour of a $31 million state-funded expansion that nearly doubles the school’s size and broadens student exposure to aquatic-based careers.
The school, which draws students from Bridgeport, Fairfield, Stratford, Trumbull, Milford, Monroe and Shelton, opens today. There are 500 students, an increase of about 150 over last year. Roughly half of the students come from Bridgeport. Students spend the morning or afternoon at Aquaculture and the rest of their school day at their home school. Aquaculture supplies them with all their science and technology credits, a chance to take University of Connecticut courses for credit and introduces them to a number of marine related careers. If fish farming isn’t their thing, they can learn how to build a boat, sail a boat or use biotechnology to come up with a product that will solve a global issue.
Walking through the addition, Curtis said an increasing number of graduates in the 22-year-old school are going into fields related to aquaculture. The addition is ready to open, but on Wednesday, was still filled with workmen, some with hard hats, drilling, sanding and pounding. Boxes were still being unpacked. Teachers were preparing classrooms. Students stopped by for a peak.
Marla Tolmie, 17, a senior from Fairfield, said she almost cried when she saw the new facility. “It’s beautiful. My brother comes in as a freshman this year so he will get the full effect,” said Tolmie, who hopes to get into the aquaculture program at the University of Maine next year. Her goal is to come back and help clean up Long Island Sound.
Amanda Anderson, 17, a senior from Bridgeport, called the addition “very, very different.”
Kirk Shadle’s senior research class used to produce Connecticut Science Fair-worthy projects in cramped lab space. Now there are spacious counters, a wet lab area for water quality testing, rows of computers and easy access to the hatchery lab.
The lab, which runs the length of the addition, includes 12 “life support systems” to regulate the water quality and temperature of dozens of tanks which will hold fish cultivated by students. Some of the fish will go to market, others will be raised as bait, and/or as ornamental fish. The lab will also raise seaweed and shellfish.
The new 33,000-square-foot wing also has a “bookless” library, rich in technology and amenable to high profile presenters and speakers. In one corner is a replica of a handmade wooden block and tackle from a historic sailing ship, donated by Kay Williams of Captains Cove, which neighbors the school.
A new Seafood Science lab will house the fish market that will be open Thursdays and Fridays. The lab has a kitchen and a chef demonstration area comparable to anything you’d see on the Food Network. Teacher Liz Kranyik will instruct students on safe handling of food for consumption or sale.
The new biotechnology lab will allow teacher Carla Ebmeyer to stop using a microwave in the back of her classrooms to make gels used in DNA work.
Parts of the existing building were renovated as well. In the fourth floor tower of the school, a classroom has been replaced with a navigation simulator that will allow students to practice sailing on five ships and ten harbors — including Black Rock, New York and Alaska — depending on the software used. It is not unlike the training given to individuals in the Coast Guard or Maritime Academy.

Scientists from various regions of the country are conducting research to find alternative ingredients to prepare food for fish.
The main objectives of these initiatives are to lower production costs and reduce the impact on the environment.
The first results of the Aquabrasil project were presented on 1 March at the Brazilian Agricultural Research Company (Embrapa), in Pantanal, Corumbá.
According to Roselany Corrêa, a researcher at Embrapa Amazônia Oriental, in Belén, experiments will include the use of dende, sunflower and coconut flour, among other products.
They will also use mango flour, passion fruit waste and Amazon fruits for the production of rations that serve to feed the tambaqui fish, one of the species that is being studied in the Aquabrasil project.
Correa said that it is necessary to refine the studies to select the best food choices.
“We can help organizations to work with the agencies responsible for rural extension, so that this knowledge reaches the farmers,” she added.
Meanwhile, Márcia Mayumi, a researcher at Embrapa Agropecuaria Oeste, in Dourados, presented some interesting results related to sanitry conditions, safety and prevention.
In addition to academic and scientific studies, Aquabrasil is generating information regarding health-related practices.
Two of the constructed reports are ‘How to send fish to the laboratory for disease diagnosis’ and ‘Main parasites in tilapia cultured in Santa Catarina.’
