Mud Cat is also refered to as turd hustlers because they can live in such bad water, shallow, hot, muddy, just before it drys up and the fishes backs are out of the mud they will finally die. They don't get much bigger than 3 to 5 pounds max.
If you see them in a small ditch in the spring early summer they will be black with lacy fins, very pretty. They are very tough and survive conditions many fish can't.
In commercial catfish ponds they are a terror. You can't get rid of them without killing everything in the pond. Catfish processors won't take them because of the Yellow meat, people won't buy it. It is very good meat though.
They raise them in northern areas because they get max size quick. Not commercially but in private ponds. eddie
