Does the midnight sun increase the feeding rate and hence the growth rate of early juvenile Arcto-Norwegian cod Gadus morhua in the Barents Sea?
The growth rate of Arcto-Norwegian cod juveniles in the Barents Sea during their first 4 mo of life is about twice that of cod juveniles in areas farther south, such as Georges Bank and the Flemish cap. Cod larvae and juveniles in the Barents Sea experience 24 h of daylight and thus the larvae and j...
