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.

Abstract | The abstract provides a clear and brief statement of the content of the resource. | 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. |
Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | • Ova deposition from individual females was estimated using the length-fecundity relationship reported by Bacon et al. (2012) for upland early running salmon. • Female salmon were considered to have contributed ova to in-stream production provided they were not spent on arrival at the traps and did not leave the stream unspent (i.e. they had successfully spawned). • The dataset does not differentiate between stocked and unstocked ova as previous work suggests no difference in outcomes by smolt life-stage. • Total ova deposition (stock) was estimated by summing the ova content of individual females in each year that contributed to spawning. • A single female had no recorded length, so a mean length was estimated from females of the same age returning in the same year. • The year of spawning for returning females (recruits) was calculated from scale read ages as follows: year spawned=return year-sea age-freshwater age-1. • Where sea age, freshwater age, or both are unknown, ages were assigned based on the proportions of freshwater / sea age combinations for returning females in each year. • Total ova recruitment was estimated by summing the ova content of individual females lagged to the year they were spawned (regardless of whether they subsequently contributed to spawning or not). • No fish were allowed to spawn naturally above the trap in 1978. As such, there are no data available for this year. • The dataset is constrained to spawning year 2009 to allow for adult returns aged 3.3. • The dataset contains some repeat spawning females (n = 37) and it is assumed that the length-fecundity relationship is the same as for first spawning fish. |
