|Relationships between the frequency of farmed escaped salmon in the spawning population, and observed changes in various genetic parameters|
|Statistic||Un-weighted mean||Weighted mean|
|Pair-wise FST 72||0.19 (0.052)||0.52 (0.0003)|
|Pair-wise FST 47d||0.17 (0.067)||0.44 (0.0014)|
|Pair-wise FST 25r||0.06 (0.30)||0.41 (0.0022)|
|FST to farm 72||0.13 (0.11)||0.22 (0.039)|
|FST to farm 47d||0.25 (0.024)||0.37 (0.0045)|
|FST to farm 25r||<0.01 (0.72)||<0.01 (0.99)|
|ABC introgression||0.16 (0.08)||0.47 (0.0007)|
|Fixed migration rate introgression||0.25 (0.025||0.36 (0.005)|
Values computed are R2 (P-value). Number behind statistics refers to number of SNP loci used, introgession computations only compared for 47d.
Pair-wise FST = observed value between historical and contemporary sample for each river; FST to farm = absolute difference in pair-wise FST between the populations historical sample and the farm sample, and between the populations contemporary sample and the farm sample, ABC introgression = estimated introgression of farmed salmon (Table 3) using ABC method, Fixed migration rate introgression = estimated introgression of farmed salmon (Table 3) using the fixed migration rate method. Un-weighted mean = mean% of farmed salmon observed on the spawning grounds for these rivers in the period 1989–2009 [5,52], weighted mean = weighted average percentage of farmed salmon in the population combining data from both sports-fishing and spawning population samples .
