ABSTRACT
The goal of
the project was to estimate chum salmon stock composition
using genetic stock identification methods for commercial
fisheries in the South Puget Sound and Hood Canal harvest
areas. Preseason abundance forecasts are based on
run sizes in previous years, which have been calculated
with accounting for the contribution of non-local stocks
to the subject fishery catch areas. The genetic stock
identification analyses showed substantial presence of
non-local stocks in these fishery catch areas.
Incorporating these new stock composition data into run
reconstruction models resulted in postseason estimates
of 1993 abundance for South Puget Sound and the Hood Canal
areas that varied by 17 percent and 8 percent, respectively,
from conventional estimates.
