By 1997, channel catfish culture was the largest aquaculture industry in the United States, with catfish production representing 72 percent (by weight) and 55 percent (by value) of the entire industry (U.S. Joint Subcommittee on Aquaculture 1999). http://text.lsuagcenter.com/en/crops_livestock/aquaculture/catfish/Production/Catfish+Production+Economics.htm RKazmierczak@agcenter.lsu.edu (Richard F.

Breeding hybrids with selected or favored characteristics of each parent is one of the goals of animal husbandry. Of all these interspecific catfish hybrids, only one hybrid has characteristics that would favor commercial application. That hybrid is the channel catfish (Ictalurus punctatus) x blue catfish (I. furcatus) hybrid (denoted as the CxB hybrid). http://text.lsuagcenter.com/en/crops_livestock/aquaculture/catfish/Production/Production+of+Hybrid+Catfish.htm web@agcenter.lsu.edu (LSU AgCenter) http://text.lsuagcenter.com/NR/rdonlyres/D0EE775A-1C83-4C93-B389-02E0A67BD865/257/hybrid_catfish_production1.jpg http://text.lsuagcenter.com/en/crops_livestock/aquaculture/catfish/Production/Scarecrowboats+Frighten+Birds+From+Ponds.htm Sun, 03 Oct 2004 23:29:01 GMT To reduce losses caused by hungry birds, aquaculture farmers spend as much as $100,000 a year on abatement programs. Now, two LSU AgCenter agricultural engineers have developed robotic boats to keep these predators out of commercial ponds. http://text.lsuagcenter.com/en/crops_livestock/aquaculture/catfish/Production/Scarecrowboats+Frighten+Birds+From+Ponds.htm RPrice@agcenter.lsu.edu (Randy R.

Well-designed ponds, constructed on soil with proper clay content and adequate water supply, have a useful life of at least 10 years. http://text.lsuagcenter.com/en/crops_livestock/aquaculture/catfish/Production/Construction+of+Levee+Ponds+for+Commercial+Catfish+Production.htm Error@agcenter.lsu.edu (Error) http://text.lsuagcenter.com/NR/rdonlyres/779FCDCD-5F04-4FBA-9B6B-B7EE75F8C777/220/construction_levee_Ponds4.jpg http://text.lsuagcenter.com/en/crops_livestock/aquaculture/catfish/Production/Site+Selection+of+LeveeType+Fish+Production+Ponds.htm Sun, 03 Oct 2004 23:29:04 GMT Considerable thought and planning should go into selecting sites for commercial fish production ponds. Construction costs, ease and cost of operation, and productivity can be greatly affected by the site selected. http://text.lsuagcenter.com/en/crops_livestock/aquaculture/catfish/Production/Site+Selection+of+LeveeType+Fish+Production+Ponds.htm Error@agcenter.lsu.edu (Error) http://text.lsuagcenter.com/NR/rdonlyres/93E71E26-DE69-4226-82CB-5166E9F8BEDA/218/site_selection_leveetype_fish4.jpg http://text.lsuagcenter.com/en/crops_livestock/aquaculture/catfish/Production/Watershed+Fish+Production+Ponds+Guide+to+Site+Selection+and+Construction.htm Sun, 03 Oct 2004 23:29:05 GMT To be profitable, an aquaculture pond must be sited properly and designed for efficiency. An inaccessible location, leaks in the pond, poor seining conditions, or lack of good quality water will doom an aquaculture enterprise to failure. http://text.lsuagcenter.com/en/crops_livestock/aquaculture/catfish/Production/Watershed+Fish+Production+Ponds+Guide+to+Site+Selection+and+Construction.htm web@agcenter.lsu.edu (LSU AgCenter) http://text.lsuagcenter.com/NR/rdonlyres/E5A1D932-6A19-4B19-B31F-9129874777BF/224/watershed_prod_ponds4.jpg http://text.lsuagcenter.com/en/crops_livestock/aquaculture/catfish/Production/Hatchery+and+Fry+Pond+Issues.htm Sun, 03 Oct 2004 23:24:34 GMT Although many catfish producers rely on commercial hatcheries for fingerlings, onsite fingerling production is an important part of many operations. The tips below address channel catfish fry production in the hatchery and managing ponds for rearing fry into fingerlings. http://text.lsuagcenter.com/en/crops_livestock/aquaculture/catfish/Production/Hatchery+and+Fry+Pond+Issues.htm GLutz@agcenter.lsu.edu (C.
