I plan on consistently harvesting fish from my yet to be dug pond, what is done with the fish carcasses and entrails? Can this be made into fish food someway?, Perhaps dog treats of some kind? I’m not really interested in making a fish stock with this waste, and I can’t put it in my garden because bears and cats will show up. When I lived in Key West they would just toss the fish remains into the water where it would be gulped up by Tarpon or nurse shark before it even hit the water. It seems like a resource, but I just can’t see it.
