As a counter point, management of US fisheries seems to be finding a good balance:
U.S. seafood catch at 17-year high
"Last year's increase, up 23% by weight over 2010 levels, is evidence that fish populations are rebuilding. Still, a number of fisheries remain in trouble."
Canada thought it was finding a good balance with increasing fish caught while the Grand Banks fishery was collapsing.
Then they discovered that improvements in technology were letting them more efficiently catch the few remaining fish, and there were suddenly no more fish left.
Therefore an increase in fish being caught is not necessarily evidence that populations are being managed sustainably. It could merely be evidence that they are being managed less carefully. (Good for now, worse in the long run.)
