Field examination of Nimpkish River sockeye timing and migration pathways in 1981 and 1982 / by A.P. Gould and A.P. Stefanson. : Fs97-4/1797E-PDF

"Scale analysis was used to identify Nimpkish sockeye from a mixed stock fishery in Johnstone Straits so that more effective in-season management could be developed. Field programs in 1981 and 1982 consisted of gillnet test fishing, an intensive scale sampling program and commercial catch sampling. Results are presented in terms of Nimpkish migration route and run timing, exploitation rate on Nimpkish sockeye, as well as analysis of age and length characteristics. Nimpkish sockeye are found to exhibit differences, not only in scale patterns, but also in migration route and population age structure. Exploitation rates are also summarized"--Abstract, page ii.
