Interannual variations in the liver condition index of cod as an indicator of temperature and feeding conditions in the Barents Sea
Background: Northeast Arctic cod, inhabiting the edge of the species area, experience variable environmental conditions and feeding resources, one of the main of them is capelin. Lipids are an important biochemical link between capelin and cod. Lipids constitute approximately 10-15% of the total wet...
