| Abstract: | In the Alaska Peninsula Management Area (Area M), weirs are a primary mode of enumeration for sockeye salmon Oncorhynchus nerka escapements into some area streams. Annually, the Alaska Department of Fish and Game (ADF&G) samples adult sockeye salmon escapements at the Nelson, Bear, Sandy, Ilnik, Orzinski rivers, and McLees lake weirs for age, sex, and length (ASL) data. Out-migrating juvenile sockeye salmon (smolt) are also sampled for age, weight, and length (AWL) at Bear and Orzinski river weirs. The biological information collected from salmon escapement, combined with catch sampling information, provide the foundation for preseason run forecasts, escapement goal evaluation, and accurate assignment of the run to stock-of-origin (run reconstruction) to some Alaska Peninsula systems. The use of this data assists with long-term management of sockeye salmon stocks while daily monitoring of the sockeye salmon escapements helps ensure that escapement goals are met. Operation guidelines for the 6 Area M ADF&G weir camps are presented, including weir installation instructions, salmon enumeration and sampling procedures, and general camp policies. |
