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
