Review of 1998 terminal run of Somass River chinook salmon, 1998 WCVI extensive escapement indicators, and Somass terminal run forecast for 1999 / B. Riddell … [et al.]. : Fs70-1/1999-165E-PDF
The detailed assessments and forecasts of the Robertson Creek Hatchery/Stamp River (Somass) chinook are undertaken annually for management of ocean and inlet fisheries and as an indicator of the expected returns to the naturally spawning chinook populations along the west coast of Vancouver Island (WCVI). The following forecasts are based on returns through 1998, assumptions of ocean fishing mortality in Alaska and Canada, and using methods previously approved by PSARC. The recommended forecast for total pre-fishery abundance of Somass/Stamp River chinook available in Canada is 76,000±20% based on averaging the Prod2 and Prod3 forecasts. This number includes both immature feeder chinook which will not mature in 1999 as well as chinook which will mature and be able to spawn in 1999.
