if i remember correctly, in Hawaii the law is that all LFS's are required to take in any unwanted fish, so that a fishkeeper who can no longer keep a large fish doesn't have to release or kill it. I think if more or all states had that law, it would force stores to be more careful about how they stock and sell fish. i think that kind of law would make stores self-regulate, and cut down on the number of unsuitable fish that are sold. If they have to worry about taking back a pacu or 25 every year, those fish will go only to homes that can support them.
