When a fishery crashes, it is dramatic and takes a long time to recover if ever. There's been plenty of fisheries like cod that one could not conceive being depleted but it has been now for decades.
Estimates of catches, mortality, existing stock are prone to error because we don't really know much about how fish live and their overall population. But once that crash happens it is known and too late. Cod crashed in 1992 and still hasn't recovered
