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.

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