In the unlikely event that I were to buy a fish and raise it and eat it I would probably get a pacu or larger catfish species. These are fish I have always wanted to own but don't because of their size... I would just eat it when it got too large. Not really my style though.
I'm glad that everybody is serious now. I was really wondering. I might get my husband a barracuda or a pacu. I know what pacu's eat but what do barracudas eat???
There are several fresh water fish sold as "barracudas" and all eat mainly fish, they don't get very big, 10-16" depending on species and are thin bodied.
