Linking vgll3 genotype and aggressive behaviour in juvenile Atlantic salmon ( Salmo salar)
Abstract We tested the possibility that vgll3 , a gene linked with maturation age in Atlantic salmon ( Salmo salar ), may be associated with behaviour by measuring aggressiveness and feeding activity in 380 juveniles with different vgll3 genotypes. Contrary to our prediction, individuals with the ge...
