Westcountry Rivers Trust (WRT) undertook fry index surveys (FIS) throughout the Sid catchment during the summer of 2023.

This is the first year of WRT surveys in the Sid catchment where six sites were selected to cover the catchment, with the intention to form a long-term data set. Surveys were funded through the Wild Trout Trust and Sid Valley Biodiversity Group. Results show that trout fry numbers were low within the catchment, however, trout parr were present at all main River Sid sites. No salmon were recorded during the surveys.

Conservation strategy Defend/Repair/Attack has been applied on a sub-catchment level dependent on classifications received during the semi- quantitative surveys.
