Well a good friend of mine told me that his stock tank level was dropping due to the lack of rain. He invited my son and I to fish and keep some of the larger catfish as he was afraid they would start dieing off. We went and caught 4 nice channels in about an hour...the largest was six pounds and the others were all 5 lbs each. I noticed immediatley that two of the fish looked normal....normal proportions with big fat bellys. The other two had heads about the size of a small shovel but with very thin bodies. I have a feeling that if they had been in a lake, they would have been 10-15 lbs easy. Anyhow, I got home and cleaned them up. I always like to examine the stomach contents to see what they have been feeding on. All of these fish were full of algae and grass! On top of that, the fillets off those two with big heads were very thin and skinny. Well there is no fish like fresh fish, so that is what we ate that night. Wow. The decision was unanimous. The fish had the texture of gar, and was very rubbery and chewy. It was not flaky at all, and reminded me of chicken. I'm assuming the big headed ones were males, and that is what we ate. The other two had big, healthy fillets and those went in the freezer. First time I've ever had bad catfish!
