Have you ever handled a Catfish? They are not the easiest fish to handle. These workers are basically butchers. They deserve more than minimum wage.
Yea, I have ... I live in Louisiana for pete's sake. You hang them up and pull the skin off and then cut the filets. It ain't rocket science, nor is it even difficult.
Have you ever butchered an animal? Even studied the cuts that are involved in butchering an animal? I have. There is not even a remote similarity to cutting up a fish.
