Major histocompatibility complex and kin discrimination in Atlantic salmon and brook trout
Abstract Many species of salmonids can discriminate kin from unrelated conspecifics using olfactory cues. In this study, we determined the role of the major histocompatibility complex (MHC) in kin discrimination by juvenile Atlantic salmon ( Salmo salar ) and brook trout ( Salvelinus fontinalis ). G...
