one which you began. The cod problem and the seal hunt are not comparable.
Really not even close. Huge differences. Canada kicks out factory trawlers, extends limit to 200 miles. Canadian catch jumps from 139,000 tonnes at that point to 250,000 tonnes as Canadian investors jump in. New fishing vessels, what we now know as the draggers become the norm. Inshore cod fisherman voice concerns, as well as scientists voicing concern over biomass numbers. Government hesitant to lay off so many people and lose so much investment.
Seal fishing. Catch size determined by surveys of whelping grounds. Actually decreased this year from last year, probably a result of less sea ice. Little investment, steady number of fishers. Most importantly, no new technology which produces a "ratchet effect'. That is, strained stocks put under more pressure by more efficient capture methods.
If we can't rely on marine scientists, who then? Certainly they know more than the top DFO knuckleheads who so often think of bottom lines rather than ecological assessments. DFO officials have learned how to keep their ass out of the fire, listen to the scientists. This includes other fisheries as well. Such as new trawl methods with two cod ends rather than one, after scientists study behaviour and find that some fish turn up when the trawl nips their caudal fins, while others do a complete 180 turn into the cod end. Larger mesh sizes to ensure the smaller fish can escape. Bans on fishing in nursing areas. And so on and so forth....
