Gene-based markers could aid selective breeding
Stress hormone axes could be used as markers for selective breeding. Researchers see a negative correlation between weight gain and cortisol response to acute stress.

SCP comparable to hydrogen peroxide as catfish egg disinfectant
In studies, sodium carbonate peroxyhydrate proved an effective alternative to formalin and hydrogen peroxide as a treatment for controlling fungal infections of catfish eggs and improving hatch rates.

Early host response improves ESC resistance in channel catfish
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.

Hydrogen peroxide treatments improve catfish embryo survival
Without hydrogen peroxide treatments, pathogens like fungi and bacteria can overtake the egg mass and significantly reduce channel catfish embryo survival.
