Stock Assessment of Early Run Skeena River Coho Salmon and Recommendations for ManagementMicroform - 1988
The Skeena River, located in north coastal British Columbia, is the second largest salmon producing watershed in the province. Concerns have been expressed for the stock status of early run Skeena River coho salmon because of declining escapement levels. Available data on spawning escapements and subsequent recruitment were analyzed using a Ricker model under various assumptions about fishery interception rates to derive maximum sustainable yield escapement levels. The analysis used a test fishing index, collected consistently since 1956, to derive the escapement to the river-mouth, rather than the usual visual observations made on the spawning grounds.
