10-million sockeye salmon were expected to return to the Fraser River to spawn this year. 9-million didn't show.
A team of ocean fisheries experts seeking to unravel the mystery now think global warming may be the cause of British Columbia's vanishing salmon stocks.
Food-poor ocean waters warmed by climate change likely played a significant role in the death of millions of sockeye salmon in British Columbia's Fraser River ahead of what was supposed to be a bumper year, says a scientific think-tank.
A group of more than 20 ocean and ecology experts gathered in Vancouver this week to discuss possible explanations for this year's salmon collapse and announced their assessment Wednesday, saying they want to keep the issue afloat with a judicial inquiry approaching.
Last month, Prime Minister Stephen Harper appointed a B.C. Supreme Court judge to probe the collapse of the stocks, but the scientists say there's much work that can be done in the meantime.
The group recommended improved forecasting, more ocean-based marine research and a more precautionary approach to fisheries management.
