Re: HELP, Yellow Belly catfish die off
As a former aquatic applicator, I would say that something may have gotten into your pond. Bullheads are very tough and if memory serves can get Oxygen from air by gulping. If it was low oxygen one would expect a wide range of species to die off. Since catfish have skin and lack scales they are suseptable to certain chemicals. But since you have other catfish and they are not dying that creates a mystery. I would suggest you contact your local fisheries biologist and request his/her assistance. Call your local fish and Game to get the biologist. If they supsect drift from Pesticides, please call the Dept of Ag for your state and file a drift complaint. They can test the water and possibly the fish to see what pesticide your dealing with if enough time has not passed to get a good sample.
