I agree things aren't looking good long-term. I didn't mean to attack your point specifically but to address the thread as a whole. The Atlantic cod collapse certainly was caused by overfishing, but the situation isn't all that comparable beyond the semi-permanence of the loss. The north Atlantic had a true tragedy-of-the-commons situation, this is most likely climate change, which is even more discouraging.

I'm in PLC/controls, so no expert on commercial fishing. Just hear/saying from those who are.

You also have to take into account the sexual maturity and number of offspring of the species.

Cod reach sexual maturity from 2-7 years, crab in 1 year. But Atlantic cod apparently lay 200k-2m eggs, alaskan crab between 50k-500k. Though I can't quite see if the cod number is lifetime or annual.

I seem to recall a huge drop in the Salmon population on the Fraser river back in the early 2000s. Seems the numbers continue to bounce around. https://www.cbc.ca/news/canada/british-columbia/fraser-socke...

Doesn't mean we don't need to know why. It's good that the crab season is cancelled, but I really feel for the crab fishermen. After the last few years, and with inflation, to lose a whole season must be devistating.
