Unfortunately they do. They might change from one species to another, but overfishing is a problem. While some fishermen might self regulate, others are out to for the quick profit without long term consideraion for the trade.
That’s what happened with cod and striped bass along the East Coast of the USA for awhile. I think sport fishermen were influential in reducing the commercial fishing season and the size of the fishing boats’ catch.
I’m not certain whether their numbers have recovered but I do know swordfish and Patagonia toothfish (AKA Chilean sea bass, which is really not a bass) numbers were also hit hard by their popularity as restaurant fare.
How long have the Turks been fishing tuna?
