Health & Welfare
Higher production typically results in higher profits at channel catfish farms, but ponds must be individually managed to maximize production.
Health & Welfare
Research with channel catfish found that the induction of puberty is a developmental process that requires temperature cycles and is independent of body size. It may be possible to achieve early maturation in channel catfish in less than two years.
Health & Welfare
Studies indicate dietary arginine supplementation may constitute an effective means of increasing immunocompetency and disease resistance of fish.
Health & Welfare
Witholding feed from channel catfish during the manifestation of enteric septicemia is a common practice, but discontinued feeding after an ESC challenge increased mortality.
Health & Welfare
In channel catfish diets, amino acid uptake from purified feed supplements is faster than from intact proteins in practical feed ingredients.
Health & Welfare
Decisions on stocking channel catfish fry should be based on the abundance of large zooplankton in the pond water, rather than total zooplankton abundance.
Health & Welfare
Columnaris disease in channel catfish is caused by Flavobacterium columnare, a gram-negative, long rod-shaped bacteria ubiquitous in freshwater environments.
Health & Welfare
Sensitive detection of enteric septicemia is important to the successful development of a selective-breeding program for ESC resistance.
Health & Welfare
Research indicates that small improvements in current management practices can significantly improve the hatching success of channel catfish.
Aquafeeds
Studies at the Thad Cochran National Warmwater Aquaculture Center show that adding menhaden oil to catfish diets can produce fillets with more omega-3s.
Health & Welfare
Feeding channel catfish broodstock once a week to satiation limited fish growth but resulted in optimum condition factor during the post-spawning phase.
Health & Welfare
The potential for genetic improvement in channel catfish should be compared to improvements in the poultry, beef and swine industries.
