Biological and fishery-related aspects of overescapement in Alaskan sockeye salmon Oncorhynchus nerka

Overescapement of salmon is defined by the Alaska Department of Fish and Game as escapements that are above the range of the current escapement goal. The understanding of how overescapement affects long and short term yields is dependent on knowledge of the production relationship and the amount of fishing power. This document reports the results of the analyzed brood and run information from 40 Alaska sockeye salmon, Oncorhynchus nerka, stocks to determine the biological and fishery-related effects of overescapement.
