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 sites include 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. This dataset provides counts of adult Atlantic salmon that have returned to the trap sites separated by sex and sea age for the duration of the monitoring period at each site. Annual sex ratios for 1SW and maiden MSW returners are reported. In addition, estimated total ova stock and recruits are reported by spawning year. Recruit ova estimates for each spawner year are subsequently reported separated by their return year.
