I searched for a while and did not find what I was looking for, so I thought I'd ask. What type of market fish is good to be used as feed for my stock. Have catfish,pbass, bichir,ck. I was using tilapia, then was told that its no good because for poor nutritional content. So what is good, a few different types would be great, just in case I can't find one or the other. Oh, and I am currently trying whiting, its a no go. Just falls apart after being thawed and not sure about the nutritional value.
