Description

This project estimated coho smolt and adult abundance in the Unuk River and gathered age, sex, length data; smolts were coded-wire tagging when emigrating and adults were monitored using a mark-recapture experiment.

Project Benefit

1. Precise estimates of total coho salmon production, exploitation and survival will be obtained from a relatively large stock (30,000 to 60,000 adults produced annually) in the southern inside area.
2. Improved in-season management for southern inside coho salmon stocks. This stock has an early to mid season run timing. This attribute is important because tag recoveries in marine fisheries are relatively stable in July and August. By standardizing in-season recoveries to the number of smolt tagged, an estimate of marine survival and run strength can be obtained early enough in the season to allow management actions to shape fisheries and exploitation.
3. Funding of this project will allow a habitat assessment of the Unuk River drainage to be conducted collaboratively with the Transboundary Watershed Project. This will provide an excellent opportunity to integrate data on coho salmon production with habitat data in a medium-sized transboundary glacial system.
4. A detailed operational plan for the CWT work will be submitted by April 15, 2001.
