Is anybody doing the fish thing? We have a guy that comes to our market with beefalo and seems to do alright with that. That's all he does, no produce. I was considering trying out some aquaculture in my greenhouse but didn't know how complicated it would be to sell the fish at the market. Talapia seems to be the fish used most in aquaculture, but I have read that catfish is also a breed that works, and since I live in where people tend to like to eat catfish, I thought it might be an option.
