There are no regulations for raising your own fish for your own consumption. Regulation becomes an issue when your fish enter commerce. Unless the IRS gets involved.er...i'm not so sure you can do that. there will probably be restrictions in your area about keeping wild native fish, and not only that, there WILL be some regulating growing them for human consumption. plus, it will be expensive. you are probably better off just going out to a lake and catching the fish that you want to eat.
My guess (and it is just that), is that there are things in the fish food that humans should not be eating. If the fish eat it, their bodies contain it, and the fish then becomes something that humans should not eat.Keep in mind that most commercial aquarium fish foods are labeled as "not for food fish". I'm not sure why this is, but it would be worth looking into if you were planning on eating them.
