Over the last 20 years the River Tweed has gained a growing reputation as a Grayling fishery with many anglers fishing for Grayling, particularly throughout the winter months. The Tweed Foundation mainly uses catch records to monitor the Tweed’s Grayling populations. As with trout, catch log books are used to monitor Grayling catches. At the end of each year, the information from the log books is collated, providing insight into the angling effort and the number and population structure of Grayling in the Tweed.
Data is also gathered from two separate angling competitions that take place each year: the Earlston Grayling Competition and the Earlston Inter-club competition. The Earlston Grayling competition provides data for the Middle Tweed in January, while the Inter-club competition provides data for the Middle Tweed and the Kelso Angling Association’s water in August. By gathering this data, we have been able to build up a database of Grayling catches going back to the mid 1990’s. This allows us to monitor the changes in the Tweed’s Grayling population structure over time.
The information gathered from catch records adds to that from previous studies carried out as part of TTGI, including the tagging of Grayling to monitor recapture rates and their movements (or lack thereof) within the catchment.
