Due to heritable population differences in run-timing, Atlantic salmon (Salmo salar) enter Scottish rivers throughout the year.  Maintenance of this diversity is vital for the continued commercial and recreational value of the associated rod fisheries, which extend on most rivers from February to September.  However, as the data we present demonstrates, management of the rod fishery on the River Spey, Scotland, is complicated by differential exploitation of the Atlantic salmon from the various run-timing groups.

To estimate the rod exploitation levels of the various run-timing groups, fishing guides on the River Spey, Scotland, floy-tagged 786 rod-caught and released Atlantic salmon, Salmo salar L., between 2000 and 2002 and recorded recaptures. Whereas 25% of the fish tagged early in March were recaptured, only 2% of those tagged early in June were caught a second time. Exploitation is biased towards the early-running stock components which current assessments show to be least abundant. Management of Atlantic salmon based on an average exploitation rate is inappropriate.

Angling effort data was collected at seven Speyside fishing estates throughout the 1992 season and catch per unit effort (CPUE) was examined fro salmon and sea trout.

During 1991 the SFB and the SOAFD (now Marine Scotland) set up a project to collect catch per unit effort data on the River Spey, a major Scottish slamon river, and this report analysis data from 1992 to 1994.
