"Fish fleeing warming waters will cross national boundaries and add new 'shareholders' to existing fisheries," said senior author William Cheung, associate professor in UBC's Institute for the Oceans and Fisheries and director of science for the Nippon Foundation-UBC Nereus Program, which helped fund the research. "Without a pre-agreed mechanism to accommodate these unexpected fish shareholders, we could witness more international disputes over the allocation of fisheries resources."

The study analyzed 892 fish stocks from around the world using models, developed by Cheung and his team at UBC, that show climate change is driving marine species toward the poles. They found that 70 or more countries will see new fish stocks in their waters by 2100 if greenhouse gas emissions continue on their current trajectory.
