An assessment of the Kitsumkalum River summer chinook, a north coast indicator stock / R.E. McNicol. : Fs70-1/1999-164E-PDF

In 1984, the Kitsumkalum River summer chinook stock was chosen for monitoring under the chinook 'key-stream' program, which was initiated in response to objectives set out in the Canada-U.S. Pacific Salmon Treaty. The goal was to use escapement and exploitation information from this stock as an indicator of harvest and exploitation rates on B.C. north coast chinook. This paper represents the first comprehensive compilation and examination of the data collected to date. Most information from 1984-1996 has been obtained or derived from data contained in a series of published manuscript reports. Data for 1997 and 1998 are unpublished. Two weaknesses in the data are apparent. The few coded-wire-tagged (CWTd) fed-fry recoveries during some years, particularly in the escapement, have probably led to exploitation rate estimates of low precision. In addition, low numbers of aging samples some years likely led to under-sampling of some age classes in the escapement. Changes to program operations have recently been made to address these two problems.
