Book Description
From July 21 to September 13, 1997, a fish counting weir was operated below the outlet of Larson Lake, a major producer of sockeye salmon (Oncorhynchus nerka) in the Susitna River Watershed. A mark-recapture (M-R) experiment revealed that the type and method of primary and secondary tagging may be critical to success of recovery sampling conducted in spawning grounds.

Book Description
The Judd, Chelatna, and Larson (JCL) lakes sockeye salmon escapement information is used by the Alaska Department of Fish and Game (ADF&G) to manage the commercial, sport and subsistence fisheries that utilize the Susitna watershed sockeye salmon, Oncorhynchus nerka, stock. Annually, ADF&G enumerates salmon escapement through a weir at each lake and collects samples of adult sockeye salmon for age, sex, and length data (ASL). The biological data collected from the salmon escapement assists ADF&G with long term management of the Susitna sockeye salmon stocks by providing information for run reconstructions and escapement goal analysis. This report includes guidelines for salmon enumeration, sampling, and data reporting procedures.
