Diel feeding rhythms and daily food consumption of juvenile Atlantic salmon in the River Alta, northern Norway
Atlantic salmon fry (0+) sampled from the River Alta exhibited only minor differences in stomach content weights and feeding rates throughout diel periods, but feeding rates were generally lowest at night. In contrast, salmon parr (1+ to 3+) had large diel fluctuations in stomach content weight, wit...
