SEATTLE — Researchers at the University of Washington say a new method for measuring biomass shows worldwide fish stocks are more stable than previously thought.
Lead researcher Trevor Branch and his team, writing in Conservation Biology, argue previous estimates were flawed by inappropriate use of trends in catches.
"Estimates of fishery status based on catches suggest that around 30 percent of fisheries are collapsed and 70 percent are overexploited or collapsed," Branch said. "Our assessment shows that the data are seriously biased, and that instead we should be looking at biomass data."
