Or, you know, don’t fish at all so we don’t kill possibly trillions of sentient fish every year for no necessary reason whatsoever?
Side bonus, we also don’t kill the highly sentient and highly intelligent creatures you’re concerned about.

Those people can all just starve, and you're fine with that?
