Book Description
This report summarizes the results of the 2016 Alaska Peninsula Management Area (Area M), Aleutian Islands Management Area (AIMA; portion of Area M), and Chignik Management (CMA; Area L) salmon catch and escapement sampling programs. The purpose of this report is to serve as a compilation of data; interpretation and discussion of these data are limited. Sockeye salmon Oncorhynchus nerka escapements and smolt were sampled throughout these management areas. In Area M the Alaska Department of Fish and Game (ADF&G) operated weirs at Bear River, Ilnik River, Nelson River, Orzinski Lake, and Sandy River; in the AIMA, a weir was operated at McLees Lake on Unalaska Island; and in the CMA, ADF&G sampled sockeye salmon at the Chignik River weir. The projects estimated escapement and collected age, sex, and length data from adult salmon. Age, weight, and length data were collected from outmigrating sockeye salmon smolt from the Bear, Orzinski, and Chignik rivers. The age structure of the late run of sockeye salmon to Bear River, the Nelson River sockeye salmon run, and Chignik early and late sockeye salmon runs were estimated from the available escapement and catch data associated with those systems, and used for run reconstruction and brood table development.
