Jake Rice, of the Canadian Department of Fisheries and Oceans, warns that collapsed cod stocks do not recover as quickly as previously thought. There seem to be several reasons for this, one is that the depleted stocks spawn young in a less efficient way and they are more vulnerable to predators, but also that even very limited cod fishing doesn’t allow for the stock to recover. The fishing fleets have also been upgraded, so even if there are smaller fleets now, they are able to fish 20% more often, not bothered by fog for example because of new GPS systems. CBC news has an article. Things are not looking good for European cod either as New Scientist previously has reported.
