Several factors—including farmed salmon—appear to be responsible for the plight of Canada’s most valuable salmon, according to research published in the journal Conservation Letters. The study, carried out by an international group of scientists and sponsored in part by Watershed Watch Salmon Society and The SOS Marine Conservation Society, found that declines in Fraser River sockeye salmon abundance are linked to interactions among three factors: pink salmon abundance, exposure to farmed salmon, and ocean temperatures.
