I started raising crayfish because I wanted an animal that would happily clean up the spare parts that I didn't want to eat (legs, head, etc). Then I found out that the crayfish I'm raising prefer an algae diet with a little meat on the side - not vice-versa. I love the crayfish and am keeping them, but it's back to the drawing board. This time with channel catfish. So here's my question for everyone out there who has had meat birds (and knows a little about catfish). Would I be able to supplement the fish's diet with spare parts? I'm mostly thinking about doing this for my quail, but if I can chop up or grind/dry other leftovers I'm fine with doing that, too. Remember, this is a supplemental food - they will still be getting their regular catfish food most of the time, with spare parts thawed or given boiled/cooked/fresh(?) on butcher days. Regular water changes would be done to keep the water from going bad. I just want to know if channel catfish could grow on a spare-part diet. Thoughts? This just seems like a great way to get even more out of raising your own birds for meat.
