Mark-recapture studies of adult sockeye salmon, Oncorhynchus nerka, have been performed in conjunction with weir operations from 1996 through 2003. The objectives of the mark-recapture program were to validate the accuracy of the weir count and to estimate the total sockeye escapement (postseason) if fish were suspected to have passed the weir uncounted. This report gives visual weir counts and abundance estimates from mark-recapture for sockeye salmon in the Chilkoot River, 1999-2003.
