LSU researchers challenge analyses on sustainability of Gulf fisheries
Date:2/18/2008

apeake Bay are badly degraded due to over exploitation and face almost certain collapse. The other, a piece by Boris Worm and 13 other authors, concludes that all of the worlds capture fisheries will be depleted by the year 2048.

DeMutsert, Cowan and their coauthors contend that these findings are misleading because they were calculated without considering the context within which these data were collected. The Gulf of Mexicos ecosystem is heavily influenced by the Mississippi River and its huge outflow there, which makes it a unique and highly productive environment supporting the fifth largest fishery by value and second largest by weight in the entire country.

These researchers simply didnt look at the nature of the Gulf of Mexico ecosystem and the populations of fish found there, said Cowan. He and DeMutsert looked at more than 40 years worth of landings and monitoring data, taking into context the particulars of the Gulf environment, and saw little to no change in the health or organization of its food web.
