Data from: Effects of domestication on parr maturity, growth, and vulnerability to predation in Atlantic salmon
Domestication can change fitness-related traits. We investigated domestication-induced changes in fitness-related traits in Atlantic salmon (Salmo salar) under naturally enriched laboratory conditions with and without threat of predation. Selection in two strains for rapid growth for 3 and 5 generat...
