Which sucks, because it is one of the few seafood's that I actually dislike. I don't like certain oily fish, and I don't like calamari other than that I like pretty much every seafood. I spearfish where I live which I like because I can only take what I am going to eat, I don't injure any other fish like pole and net fishing does and everything I take is of legal size. It allows me to be more selective of what I take. I tend to target, hogfish, mangrove / mutton snapper and lionfish as the reproduce fast and are able to withstand the pressure of fishing. While it is legal during certain times, whee I live, to take grouper, tuna and permit, I tend to avoid taking them as they are more susceptible to fishing pressure.
I have spearfished for over 30 years and it is astonishing how much the fish population has declined even in my lifetime.
I personally enjoy calamari, but it definitely doesn't hit the spot for bony fish / shell fish cravings. And it is missing the omega-3's of oily fish. :(
IIRC, to paraphrase the reasoning: "they're overpopulated, their caught in not-too-damaging ways, they're healthy if you don't fry them, and they would totally eat you given the chance."
