Selling just farm-raised fish doesn't do it. A lot of them are fed smaller fish that was wild-caught. Sardines in some areas are overfished for this exact reason. On the other hand Alaska salmon is all wild-caught and they limit the catch enough to keep the population sustainable (though there's not near enough to meet the global demand for salmon that way).

Catfish farming in the US is great, and same for mollusks.

Upvoted because you make valid points.

However, fish don't have to fed other fish. Once again, there might be a solution in the mass farming of insects and worms.

I am not a biologist, but I have been fishing. The species I was after seemed to really enjoy creepy crawlers.

I'm almost positive we could make fish flake out of hard shelled insects.
