Alternative male life‐history tactics as potential vehicles for speeding introgression of farm salmon traits into wild populations
Abstract Releases of cultured organisms, such as farm Atlantic salmon ( Salmo salar L.), threaten native biodiversity and the integrity of natural communities. Salmon escaping from sea farms, however, have relatively poor reproductive success, suggesting that the rate of spread of domesticated trait...
