Chignik Management Area Salmon Escapement Sampling Operation Plan, 2012.

摘要

The Alaska Department of Fish and Game samples sockeye salmon Oncorhynchus nerka at the Chignik River weir for age, length, and sex determination to provide information for preseason run forecasts, escapement goal evaluation, and run reconstruction. Every week throughout the season, 240 sockeye salmon are sampled. Sockeye salmon scales are collected using established protocols common to the Westward Region. This report summarizes the specific procedures for the sockeye salmon escapement sampling program.
