Abstract

This is the Gunnislake Fish Counter, Annual Report 2003 produced by the Environment Agency South West Region on March 2004. The report presents the daily upstream counts of migratory salmonids recorded at Gunnislake weir fish counting station and trap (River Tamar SX 435 713) in 2003. Data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the National Spring Salmon Bylaws. The total combined annual count of upstream migrating salmon and sea trout on the River Tamar in 2003 was 7% higher than the 9-year average. The minimum salmon count for 2003 was 3626. The 2003 upstream count for sea trout was 9913. Trap data for 2003 is consistent with historic trapping and net data in terms of the size split between salmon and sea trout stocks.
