Hello,
Yes; i don't see why not, yes it might be cruel but how can you say that when you eat a piece of bacon or a piece of ham or beef humans have to eat no matter what it is, go ahead but i would do a couple of things to make it safe first, type it in on google and see what comes up. and the larger the fish i bet the more its going to fill you up and also the more nicer its going to taste, YUM!
