Relatedness and body size influence territorial behaviour in Salmo salar juveniles in the wild
Abstract Wild Atlantic salmon, Salmo salar L., juveniles defend territories to enable exclusive access to food resources, and kin selection benefits may be accrued where territorial boundaries of relatives overlap. This study explored space sharing events between pairs of sibling and non‐sibling fis...
