I'm missing the logic here. The Maine lobster fishery (which is what this article is about) is in good shape. Therefore, ALL fisheries are in good shape?????
Or are you saying, based on what you write, that because they pulled out 67 million pounds of lobsters (three times what they pulled out 20 years ago), then global warming doesn't exist????
Wouldn't this be the same area of the world and ocean where the Georges Banks were some of the most productive fishing grounds in the world, producing record catches each year . . . until there was widespread species collapse due to over-fishing????
Any of these problems require a global view, not just a snapshot of one small (relatively speaking) area to proclaim "There's no problem."
In all seriousness, the biggest probem here is not what's being brought out, but what percentage of the total specicies that represents, and is that at a level that still make the specicies take sustainable?
For instance, suppose you took out 10% of the popluation one year, 20% the next year, and 30% the year afater that. You could proclaim that you were taking out 3 times as many as you used to and draw the conclusion that therefore it was a healthy fishery.
But that would overlook the fact that you removed 60% of the population, minus whatever numbers were replenished. If there were as many new lobster born as were taken out, and if the time to reach sexual maturity roughly measured the time it took to go through the adult population of lobsters, then you might have a sustainable fishery, though you'd likely see an overall size reduction over the years.
But to point to just ONE aspect and essentially conclude everything else is an over-reaction and wrong is just over-simplifying a complex issue to score debating points and is also plain bad scinece and bad logic.
I mean, there's plenty of Blue-Banded Gobies around, so should we therefore remove all the rockfish restrictions????
