Arginine: Essential element in fish nutrition, health
Studies indicate dietary arginine supplementation may constitute an effective means of increasing immunocompetency and disease resistance of fish.

Temperature cycles induce early maturation in channel catfish
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.

Feed deprivation reduces resistance of juvenile channel catfish to ESC
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
Source affects amino acid uptake in channel catfish diets
In channel catfish diets, amino acid uptake from purified feed supplements is faster than from intact proteins in practical feed ingredients.

Managing natural productivity in channel catfish nursery ponds
Decisions on stocking channel catfish fry should be based on the abundance of large zooplankton in the pond water, rather than total zooplankton abundance.

Studies move toward standardized challenge model for Columnaris in channel catfish
Columnaris disease in channel catfish is caused by Flavobacterium columnare, a gram-negative, long rod-shaped bacteria ubiquitous in freshwater environments.

Genetic detection of bacteria improves selective breeding in channel catfish
Sensitive detection of enteric septicemia is important to the successful development of a selective-breeding program for ESC resistance.

Channel catfish seedstock: Studies yield suggestions for hatching success
Research indicates that small improvements in current management practices can significantly improve the hatching success of channel catfish.

Feed supplementation with menhaden oil elevates omega-3 HUFAs in catfish fillets
Studies at the Thad Cochran National Warmwater Aquaculture Center show that adding menhaden oil to catfish diets can produce fillets with more omega-3s.

Effect of post-spawning feeding on reproduction in channel catfish
Feeding channel catfish broodstock once a week to satiation limited fish growth but resulted in optimum condition factor during the post-spawning phase.

Genetic improvement of channel catfish
The potential for genetic improvement in channel catfish should be compared to improvements in the poultry, beef and swine industries.
