Girnock and Baddoch: Adult Return Rates dataset https://portal.medin.org.uk/portal/start.php?tpc=012_Marine_Scotland_FishDAC_1607 The Girnock and Baddoch catchments are long-term monitoring sites where the population dynamics of spring salmon have been assessed since 1966 and 1988 respectively. These long-term monitoring sites consist of a pair of fixed traps designed to catch emigrating juvenile salmon and returning adults. Trap protocols were similar, although not identical, over the monitoring period. See Soulsby et al. (2024) for a detailed description of the dataset and interpretation of trends.
