J. Tyrell DeWeber, James T. Peterson, Cameron Sharpe, Michael L. Kent, Michael E. Colvin, Carl B. Schreck
2017, North American Journal of Fisheries Management (37) 162-175
After returning to spawning areas, adult Pacific salmon Oncorhynchus spp. often die without spawning successfully, which is commonly referred to as prespawn mortality. Prespawn mortality reduces reproductive success and can thereby hamper conservation, restoration, and reintroduction efforts. The primary source of information used to estimate prespawn mortality is collected through carcass surveys,...
