MISSISSIPPI STATE -- For more than two decades, catfish producers across the Southeast have used Mississippi State University-produced software to help manage their operations. The latest version, Fishy 2003 Version 4.0, is now available through Catfish Farmers of America.
"A licensure agreement between Mississippi State and Catfish Farmers of America to market Fishy 4.0 was signed in April," said Fishy programer and MSU professor of agricultural economics Wallace Killcreas. "So far, farmers owning more than 24,000 water acres have bought one-year licenses."
MISSISSIPPI STATE -- A Mississippi State University study reveals that while catfish producers have experienced lean times recently, the industry continues to spur the state's economy.
MSU agricultural economics professor Terry Hanson co-authored "Economic Impact of the Mississippi Farm-Raised Catfish Industry" with two MSU Extension Food and Fiber Center professors, Stuart Dean and Steve Murray. Hanson said he believes the many benefits of farm-raised catfish to consumers can create a demand that will more than make up for low market prices since 2000.

MISSISSIPPI STATE -- After facing their lowest levels in 20 years, catfish prices may be on the rise.
"After about a year and a half of struggling with low prices, catfish producers may see prices rising from 55 to 60 cents per pound to around 65 cents per pound within the next few weeks," said James Steeby, Mississippi State University Extension aquaculture specialist.
Catfish prices had declined due to an oversupply in the market. The supply should become short again soon, causing demand to exceed supply and prices to rise.
MISSISSIPPI STATE -- The nation's first specific-pathogen-free fish hatchery is up and running at Mississippi State University.
Located adjacent to and operated by MSU's College of Veterinary Medicine, the 4,500-square-foot aquatic hatchery is a state-of-the-art facility for rearing catfish and other species in a disease-free environment.
MISSISSIPPI STATE -- Catfish processors nationwide are invited to attend the 2003 Catfish Processors Conference Feb. 25 and 26 at Mississippi State University.
The catfish processors conference provides information on the processing and marketing of catfish for those involved in the production and processing of catfish. It is sponsored by MSU's Extension Service Food and Fiber Center and the MSU Department of Food Science and Technology.
MISSISSIPPI STATE -- Growers of freshwater prawns, one of the state's smaller and newer crops, wrapped up harvest in early October with what appears to be profitable yields.
Mississippi has at least 1,000 water acres in commercial prawn production in the state. There is no state yield estimate, but Lou D'Abramo, professor with the Mississippi Agricultural and Forestry Experiment Station, said several growers reported yields of 800 to 1,000 pounds an acre.
MISSISSIPPI STATE -- Researchers at Mississippi State University who are trying to formulate the best diet for catfish have found a protein mix that seems to be the most efficient.
Protein is added to catfish diets from either plant or animal sources. Catfish need protein for the same reasons every other living thing needs protein -- bodies cannot make certain amino acids needed to function and must get these from food.
GREENVILLE -- The 1990s were times of growth and prosperity for the catfish industry, but these days, Delta farmer Brent Johnson would just like to break even on his production costs.
Johnson said catfish are bringing between 55 and 56 cents a pound when he sells them to processors. Since it costs him close to 70 cents a pound to grow the fish, he is losing money on every pond he harvests this year.
MISSISSIPPI STATE -- Mississippi leads the world in catfish production, but for various reasons, the state's children may not be introduced to fish on their plates as soon as they should.
As the Bolivar County home economist with Mississippi State University's Extension Service, Sharon Allen works in the heart of catfish production -- the Mississippi Delta. She sees firsthand what children are eating and what they are not eating. She also knows the importance of consuming a variety of foods to maintain a healthy diet.
MISSISSIPPI STATE -- An oversupply of catfish, economic recession and imports have driven catfish prices to their lowest in years, but farmers are just happy that people have continued to buy as much of their fish as before.
Jimmy Avery, associate Extension catfish specialist at Mississippi State University's Thad Cochran National Warmwater Aquaculture Center in Stoneville, said the only bright spots for catfish farmers are fairly low feed prices and continued demand for the product.
MISSISSIPPI STATE -- Catfish producers have an updated tool to help them remain afloat in financial hard times.
Fishy 2002 is the latest version of computer software developed in 1982 at Mississippi State University to aid the aquaculture industry. Wallace Killcreas, Fishy programmer and Mississippi Agricultural and Forestry Experiment Station agricultural economist, said the program aids management and decision-making.
MISSISSIPPI STATE -- The recent market's demand for larger catfish has helped the industry become more efficient, but it also increases the risk to producers.
Harvest-ready catfish today weigh between 1 1/4 to 3 pounds and average 1 1/2 pounds. Until recently, catfish averaging 1 1/4 pounds were considered market-size fish.

MISSISSIPPI STATE -- Mississippi State University researchers are working to reduce the health challenges mass production of catfish can bring, which are similar to the issues faced by other food animals such as poultry and swine.
"Anytime you have intensive management situations, you can have various outbreaks of disease or parasite problems," said Dr. Linda Pote, parasitologist with MSU's College of Veterinary Medicine.
MISSISSIPPI STATE -- About the only way Mississippi farm-raised catfish resemble other fish found in the state is that they all live in water.
Catfish are grown commercially under controlled conditions. Every aspect of their production is carefully managed to ensure a consistently high harvest and to protect the quality of the product.
Mississippi leads the world in catfish production. In 2000, the state had 110,000 acres of catfish ponds while the nation had a total of 190,000 acres.
MISSISSIPPI STATE -- Catfish farmers have economic evidence that battling the most common cause of off-flavor with copper sulfate brings higher profits.
Research shows that adding copper sulfate to catfish ponds to kill blue-green algae greatly reduces problems with off-flavor. By treating to keep the fish on-flavor, producers can expect higher profits.
MISSISSIPPI STATE -- A short-term study of a common catfish pond treatment suggests copper sulfate is an environmentally sound procedure for controlling off-flavor problems.
John Hargreaves, Mississippi Agricultural and Forestry Experiment Station aquaculture biologist with the Thad Cochran National Warmwater Aquaculture Center, completed a study of the effects of copper sulfate applications to catfish ponds over three years.

MISSISSIPPI STATE -- Computer software can ease the burden of paperwork in fish farming, and the latest release of Fishy 2001 will continue to help farmers make the most of their ponds.
On April 1, Fishy 2001 a microcomputer program developed at Mississippi State University will be available for fish farmers. Fishy records, analyzes and makes reports for fish farmers to keep track of fish numbers, feedings, weights and sizes.
MISSISSIPPI STATE -- Heat has traditionally threatened Mississippi's catfish, but this year's hot temperatures have not been an issue as most producers are equipped for the challenge.
Algae in catfish ponds supply the oxygen catfish require during the day, but at night the catfish rely on aerators. With high temperatures, catfish require more oxygen in the water. July's near record nighttime temperatures meant catfish producers had to run aerators all night every night and even some cloudy days.
MISSISSIPPI STATE - Biologists are encouraging Mississippi catfish producers to control snails in ponds to combat a parasite that caused some severe fingerling losses last year.
1999 was the first year this internal parasite, a trematode tentatively identified as Bolbophorus confusus, was found in Mississippi Delta channel catfish. It is rarely fatal to large catfish, but it can kill young catfish, or fingerlings.

MISSISSIPPI STATE -- Catfish is not a new agricultural commodity to Mississippi, but research is underway on a new variety that may replace channel catfish as king of the farm ponds.
As a relatively new and growing industry in East Mississippi, catfish has emerged as a viable economic entity in the hilly Blackland Prairie region of the state. For the last 10 years, East Mississippi production has been primarily in Kemper, Noxubee, Lowndes, Clay, Monroe and Chickasaw counties, but there were no local suppliers of fingerlings.
