Feeding chronology of Atlantic salmon parr in subarctic rivers: consistency of nocturnal feeding
During the ice‐free season in three subarctic rivers in northern Norway and Finland, Atlantic salmon parr Salmo salar exhibited significant diel fluctuations in stomach content weights in August and September, the largest weights being recorded consistently at 0300 hours. Accordingly, the feeding ra...
