For a slightly different take:
Long long ago, I was a fishery biologist working for the Gulf of Mexico Fishery Management Council and often watched in frustration as fishery after fishery was allowed to be over-fished into near oblivion. As soon as somebody would suggest some serious limit on catch (which was obviously needed) 200 fishermen would stand up and howl. And little got done. I don't follow the councils much anymore, but something seems to have changed for the better. I'm all in favor.
Tell you a story that illustrates some of the problem. I was taking testimony from a spotter pilot of king mackeral, about how abundant the fish were and why no regulation was needed (this at a time when the fishery for kings was collapsing fast). He was telling the truth, he saw lots of fish, and he had been spotting for 5 whole years. He hadn't seen any reduction, there's more than there ever were, so there must not be any problem. Trouble is,5 years isn't very long, He hadn't been around for the 30 years or more that the fishery had been declining, when the fish were so abundant nobody needed an airplane to find them. His "eye witness, experienced" view was just plain ignorant.
Snapper are not my thing, grouper and hogfish are, and have been for 40 years. There was a time when, If I didn't have 150 lbs of grouper(all speared) in the boat by 2 pm, I'd had a very bad day. I've seen the steady progression of decline in those resources in the eastern Gulf and S Florida, personally. Few, if any, of my old spots have any fish at all on them today. Some extremely restrictive measures are long, long overdue. I'll not try to second guess those who are making the details of those decisions. Thankfully, they don't seem to be listening to howling fishermen.
