An aquaculture/fisheries doctoral program proposed by the University of Arkansas at Pine Bluff gained the respect of professionals charged with critically reviewing the program.
“They will be an incredibly competitive program,” said Bobby McGhee, dean of the University of Arkansas for Medical Sciences Graduate School. “They’ll be able to select from the best.
“If they gave Nobel Prizes for aquaculture, there would be four or five on this campus. The faculty is stellar when stacked against any school in the nation.”
McGhee has reviewed more than 100 proposed Ph.D. programs and he has been involved in launching six doctoral programs. He said UAPB’s proposed program is the most exciting one he has known.
The aquaculture department has been working for about 10 years to build a Ph.D. faculty and upgrade facilities in preparation for the program.
“This will not be a token partnership,” McGhee said. “We are fully on board.”
He said UAMS would give fisheries students opportunities to work in facilities such as a microbiology laboratory to learn from the expertise of a wider variety of Ph.D.s in practice.

National Catfish Day
Did you know that President Reagan issued a Presidential Proclamation in 1987 that issued today June 25th as National Catfish Day? Today, we celebrate catfish and its growing popularity in America. This delectable fish can be prepared in numerous ways, so don't go through the day without at least trying a sample!
U.S. Farm-Raised Catfish is a lean fish and an excellent source of protein. It is low in saturated (bad) fat and is a moderate source of polyunsaturated (good) fat and omega-3 fatty acids.
Ninety-four percent of all U.S. Farm-Raised Catfish is raised in Alabama, Arkansas, Louisiana, and Mississippi, in freshwater ponds filled with clean and clear well water. The National Audubon Society, Monterey Bay Aquarium, and Environmental Defense all recommend U.S. Farm-Raised Catfish as a safe environmental choice.

Stimulus Money Coming to Arkansas Fish Farmers
KATV 7 News
posted 06/15/09 9:52 pm
Little Rock, AR - Stimulus money is on the way to Arkansas fish farmers. Fifty million dollars was just approved nationally for aquaculture farmers. Arkansas will see about 7 million of that and some farmers say it will keep their business afloat.
Thousands of Arkansas's acres are home to goldfish, catfish, and hybrid striped bass breeders. After more than a year of their feed costs spiking, they see any help as relief. Swimming upstream is how some local fish farmers felt in Keo when their feed costs ballooned in 2007. Prices increased from $800 per ton to $1,200.
(Mike Freeze, Co-Owner Keo Fish Farm) “Your aquaculture farmers are a big part of the Arkansas agriculture.”
With $7 million from the stimulus package being split among all the fish farmers, Mike Freeze isn’t sure how much he'll see, but he's says it will be put to use.
(Freeze) “For every dollar that a fish farmer spends it has 7 times that impact on the local economy.”
The plans for his portion will go toward feed to keep from drowning in the current economy.
(Freeze) “I honestly feel like I'm getting back some of my tax dollars that I pay.”
He says he plans to get his paper work in by Monday and the government will be cutting checks for the farmers next week.

Aquaculture industry gets USD 50 mln for fish feed

A federal stimulus package going to the struggling aquaculture industry will include USD 50 million to be used on fish feed. The US Department of Agriculture (USDA) will distribute it in the form of grants through state agriculture departments based on amounts of feed utilised in 2007.
Feed increased in cost by over 50 per cent last year, aggravating the difficulties suffered by the national aquaculture industry caused by foreign competition. Supporters believe the stimulus package will be able to sustain fish farms and preserve jobs in the areas most affected by the economic recession and other factors, reports The Associated Press.
It was producers in Arkansas and the South who pressed the most for the package through US Senator Blanche Lincoln, D-Arkansas, who is particularly worried about the catfish industry. According to the USDA, in 2007 the aquaculture industry was worth USD 1.4 billion, one-third due to catfish sales from Mississippi, Alabama and Arkansas.
Mike Freeze, vice president of the Pine Bluff, Arkansas-based National Aquaculture Association said that a considerable amount of fish farmers are located in poor regions and have been hit with both higher feed prices and higher electricity costs in addition to foreign competition.
The fish feed purchased with the stimulus package could stretch from the South through the Pacific coast, feeding everything form shellfish to catfish, tilapia and trout.
Fish feed for commercial fish includes corn, wheat, soybeans and fishmeal as the main ingredients. It is the increases in prices of corn in particular that drove the prices of fish feed to rise.
It is processors, who have not increased pay, who hold the power to set prices. While farmers producing baitfish have been able to up their prices in accord with those of fish feed, farmers raising fish for human consumption are stuck.
"Our catfish farmers have been taking it on the chin the last couple of years," said Freeze.
Meanwhile, non-fish farmers in similar situations want to know why they are not receiving any financial aid.
"I don't begrudge the aquaculture because someone was able to get aquaculture funding," said Missouri Agriculture Director Jon Hagler.
"I think that's fantastic, and we're going to take advantage of it because if we don't we lose it. But in terms of the other industries, I just wish there was more available for them."

International trade panel upholds order against certain Vietnamese fish
By Associated Press
4:45 PM CDT, June 15, 2009
WASHINGTON, Ala. (AP) — The U.S. International Trade Commission has upheld an order against dumping of certain frozen fish fillets from Vietnam, a move described by an Alabama congressman as a victory for catfish farmers.
U.S. Rep. Artur Davis of Birmingham said it is important that farmers have an opportunity to compete with foreign producers on a level playing field.
The commission voted unanimously Monday to continue the trade protections. In May, Davis led a bipartisan coalition in support of the antidupming rules.
Mississippi and Alabama are the country's top catfish producers.

Mississippi catfish farmers say Vietnam is sinking their business
Los Angeles Times, June 15, 2009
By Richard Fausset and Richard Simon
The millions of pounds of Vietnamese fish imported to the U.S. each year are not classified as 'catfish' and may not be subject to the same inspection regulations that will soon apply to the American
Reporting from Belzoni, Miss., and Washington -- In Vietnam there's a kind of fish that's white-fleshed and whiskered and otherwise pretty darn catfish-like. But in the eyes of the U.S. government, the creatures aren't catfish.
Now fish farmers in the American South fear this government classification will allow the Vietnamese fish to slither around inspection regulations that will soon apply to American catfish.

Update on the Aquaculture Feed Stimulus (Recovery Act – 2008 Aquaculture Grant Program)
The Recovery Act authorizes $50 million of Commodity Credit Corporation funds for grants to states that agree to provide assistance to eligible aquaculture producers for losses associated with high feed input costs during the 2008 calendar year.
We still do not know how long it will take for the money to get to fish producers. The latest time line is as follows:
1. A press release from USDA on Tues.June 2.
2.Agreements will be mailed to State Department of Agriculture on June 2
3.Agreements must be signed and returned to USDA.
4.States must submit applications,guidelines and work plan to USDA for approval.
5.After approval USDA will sent the money to the states.
6.The State must advertise the grant program and sign up all eligible aquaculture producers in the state.
7.Depending on how the program is designed,the state will have to notify the producers and the feed mills how much in feed credits the producers will receive or send a check to the producer for that amount.

Evaluation of a Barrier Confinement System for Channel Catfish, Ictalurus punctatus, Production
from Journal of the World Aquaculture Society, Volume 40 Issue 3, Pages 402 - 409
by Neil J Pugliese, David Heikes, Carole R Engle
An in-pond confinement system to separate channel catfish, Ictalurus punctatus, by size within a single pond provides an opportunity for improved growth of understocked fish in ponds with larger market-sized fish. A barrier of polyvinyl chloride[ndash]coated galvanized wire mesh was constructed in five 0.10-ha earthen ponds to partition the pond into one-third and two-third sections, while five other 0.10-ha ponds were left as traditional open ponds for a control. To evaluate catfish performance in this confinement system, fingerlings (25 g) were stocked at 14,820/ha into the smaller one-third section of the barrier and carryover fish (408 g) at 2580 kg/ha into the larger two-third section of the barrier. The control ponds were stocked with the same sizes and numbers of fish in a traditional earthen pond without a barrier. Yield, survival, feed conversion ratio (FCR), growth, and economics were compared between treatments. Fingerling yields were greater in the barrier system that allowed fingerlings to be separated physically from larger carryover fish. There were no differences in yield of carryover fish, survival, FCR, or growth between the control and the barrier ponds. Partial budget analysis revealed a positive net change of $367/ha or $38,125 for a 104-ha catfish farm (at a market price of $1.54/kg of additional stockers produced). The value of the greater weight of understocked fish produced in the barrier system was greater than the annualized cost of installing the barrier, for farmers raising fish in multiple batch. Thus, on an experimental basis, the confinement system was economically profitable; however, trials on commercial farms are needed to evaluate performance on a larger scale.
