One Fish, Two Fish, False-ish, True-ish http://apocadocs.com/s.pl?1304424164
Two University of Washington scientists have just published a study in the journal Conservation Biology in collaboration with colleagues from Rutgers University and Dalhousie University arguing that the gloomiest predictions about the world's fisheries are significantly exaggerated.
The new study takes issue with a recent estimate that 70 percent of all stocks have been harvested to the point where their numbers have peaked and are now declining, and that 30 percent of all stocks have collapsed to less than one-tenth of their former numbers. Instead, it finds that at most 33 percent of all stocks are over-exploited and up to 13 percent of all stocks have collapsed.
It's not that fisheries are in great shape, said Trevor Branch, the lead author of the new study; it's just that they are not as badly off as has been widely believed....
But Dirk Zeller, a scientist at the University of British Columbia who is on the other side of the debate, doesn't buy all of Dr. Branch's arguments.... "Where their argument falls down is that they extrapolate that pattern to global fisheries, and then say global fisheries aren't doing that bad," he said. "They totally ignore the fact that all of Asia, all of South America, all of Africa are not included."...
“I have no argument with the point that with stocks that are well managed you can have sustainable fisheries,” Dr. Zeller said....
Dr. Branch, for his part, says that catch data has value for some uses as long as it is handled with care.
