The Science of Global Warming -- impact on fisheries

Link: Science -- This Week in Science {24 June 2005; 308 (5730)}.

Research published in Science on Friday:

Climate change is well established as a potential threat to biodiversity and the services and benefits that people gain from ecosystems. Perry et al. (p. 1912, published online 12 May 2005) examined the effects of climate change on a key ecosystem service, marine fisheries. Many species have exhibited a strong northward shift during the last 25 years in the North Sea. Many commercially important fish such as cod, whiting, and anglerfish have shifted from 50 to 800 kilometers northward. If current climate trends continue, some species may have withdrawn completely from the North Sea by 2050.
