Warm water blamed for lowest sockeye salmon run on record
Warm summer temperatures may have Lower Mainlanders feeling good, but they are proving lethal for sockeye salmon. The Pacific Salmon Commission recently revised its already low forecast for sockeye numbers from 2.3 million to 1.1 million in the Fraser River, which would be the lowest number since records have been kept. As of August 12, the DFO has suspended all sockeye fisheries in response. John Reynolds, professor of aquatic ecology and conservation at Simon Fraser University, said three main factors are contributing to this year’s low numbers: a small parental generation; a “blob” of warm water in the Pacific Ocean; and higher-than-normal temperatures in the Fraser River. Sockeye spawn over a four-year cycle, and Reynolds said the last cycle’s already low numbers meant low numbers were a distinct possibility for this year. Read the rest here 11:39
