Pages : 96
Book Description
Roughly 1.1 million sockeye salmon Oncorhynchus nerka were enumerated through Alaska Department of Fish and Game (ADF&G) salmon counting weirs in the Kodiak Management Area (KMA) during 2009. Adult sockeye salmon were sampled for age, sex, and length on river systems in the KMA and scale samples were taken from approximately 11 thousand salmon to represent escapement age compositions.

Kodiak Management Area Salmon Escapement and Catch Sampling Results, 2015
Author: Michelle L. Wattum

ISBN:

Pages : 97
Book Description
Over 2.1 million salmon were enumerated through Alaska Department of Fish and Game (ADF&G) salmon counting weirs in the Kodiak Management Area (KMA) during 2015. Of these fish, over 1.4 million were sockeye salmon Oncorhynchus nerka, which are the focus of sampling efforts. Approximately 9,600 adult sockeye salmon were sampled for age, sex, and length (ASL) on major river systems in the KMA; these data were used to represent escapement age compositions. The predominant age classes in the escapement were age-2.2 (52.0%), -1.3 (15.9%), and -2.3 (10.7%) fish, but primary age classes varied by system. Commercially caught sockeye salmon were sampled by ADF&G for age estimation from several areas throughout the KMA. Approximately 13,000 scales were used to represent a combined commercial harvest of approximately 2.3 million sockeye salmon from sampled areas. ASL samples collected from the 2015 commercial catch revealed an age structure composed predominantly of age-1.3 (37.2%), -2.2 (34.1%), and -2.3 (13.8%); however, primary age classes varied by section and district. Sockeye salmon brood tables were updated for the Ayakulik, Frazer, Karluk, and Upper Station systems; 10-year average return-per-spawner estimates ranged from 1.3 for the Karluk early run to 2.8 for Frazer. The examination of historical trends in sockeye salmon age compositions shows tremendous variability within and among systems.
