Review of 1997 terminal run of Somass River chinook salmon and terminal run forecast for 1998 / B. Riddell, W. Luedke, and J. Till. : Fs70-1/1999-68E-PDF

Based on returns through 1997 and using methods approved by PSARC, the recommended forecast for the total terminal run of Robertson Creek Hatchery and Stamp River chinook (age 3, 4, and 5) to Barkley Sound in 1998 is 58,800±20% (based on averaging the Prod2 and Prod3 forecasts). The age structure of the return is projected to be 8% Age 3, 72% Age 4, and 20% Age 5; with an expected sex ratio of 52% females. The number of chinook required to meet the minimum escapement goal is 31,900. While the condition of most naturally-spawning chinook populations along the west coast of Vancouver Island (WCVI) have improved over recent years, the relatively weak return forecasted for the RCH/Stamp stock and additional concerns indicate a continued need for conservative management plans in fisheries impacting these stocks during 1998.
