Spawning behaviour and success of mature male Atlantic salmon ( Salmo salar ) parr of farmed and wild origin
We examined genetic differences in the reproduction of an alternative maturation phenotype in Atlantic salmon (Salmo salar) by comparing the spawning behaviour and success among farmed, first-generation hybrid, and wild mature male parr raised in similar environments. Parr competed for spawning oppo...
