Climate change patterns to impact global spread of fish stocks

Climate change patterns over the next three to four decades will cause dramatic changes to the productivity of fish catches, a new study has found. According to Daniel Pauly, a fisheries expert at the University of British Columbia (UBC), the catch potential will decrease by 40 percent in the tropics and increase by 30 to 70 percent in regions with a high latitude. This will affect ocean food supplies around the world.
