Thanks for intrest in better ways to farm fish via free range fish. Not to discourage you but my concern is that right now we are having trouble with oceans and what looks like the amount of biomass in our migratory routes of Salmon and on both coasts. Be it global warming or some other problem we do not have enough food out there now for our wild fish and crappy hatchery fish. Anyway it's looking that way. So my thought is do we need more compition for what we have. With aqua culture raping our seas for fish food world wide to feed their farm fish and shrimp we are in big trouble on the high seas. Do we need more non wild fish in the food chain right now?
