Chignik River Sockeye Salmon Inseason Genetic Stock Identification Operational Plan, 2012.

摘要

In order to achieve escapement goals for the Black Lake and Chignik Lake sockeye salmon stocks simultaneously, as well as maximize surpluses available to subsistence and commercial harvesters, inseason estimates of the proportion of each stock in the daily escapement to the Chignik River are required. Genetic stock identification can be used to identify the proportion of Black Lake early run and Chignik Lake late run fish as they pass the Chignik River Weir. During 2012, fin clips will be taken from sockeye salmon caught in the Chignik Weir trap and preserved in ethanol. Samples will be expeditiously sent to the Gene Conservation Laboratory in Anchorage for inseason analysis.
