11-29% of Sockeye Salmon that crossed between commercial fisheries in Bristol Bay, Alaska, were injured from previous commercial gillnet entanglement, resulting in reduced survival and impaired reproduction. More than half of injured fish did not spawn, despite being from spawning populations, which means the estimate of spawning individuals is too high by at least 5-15%.
