The USDA marine aquaculture center is addressing genetic improvement of North American Atlantic salmon to develop improved lines for producers.

In a challenge study of catfish families identified as resistant or susceptible to enteric septicemia (ESC), immune response was activated 24 hours earlier in resistant families and bacterial levels were suppressed.
Sensitive detection of enteric septicemia is important to the successful development of a selective-breeding program for ESC resistance.
Although research on catfish genetics began in the 1960s, applications of genetic improvement in aquaculture have lagged behind other animal industries.
