As an immediate response, I would stop feeding and I would seine the pond at the soonest possible opportunity. I would remove the most affected. I would return no more than 1/2 the seine haul by weight or 150 lbs which ever is greater. I might do two hauls. If your standing weight is less than 150 lbs, they will recover on their own but you must curtail feeding until things turn around.

If you would give a history of your pond, your goals, stocking rate(s), catfish reproduction, feeding rates, harvest practices, etc. , then I could better help with ideas to help possibly prevent this from happening again. Generally, catfish are resistant to disease and wounds heal rapidly ... but when densities are high, they are more susceptible to disease because they are weakened by other limiting factors. In other words, their immune system doesn't work properly when they are stressed. Hope you are able to resolve this soon, please keep posting if additional help is wanted.
