The effects of seasonal acclimatization (i.e. simulated autumn and winter water temperature and photoperiod) on the specific growth rate, liver‐somatic index, white muscle protein and RNA concentration of juvenile cod were investigated. Winter acclimatization resulted in cod having higher liver‐somatic indices and white muscle RNA concentrations. The influence of environmental conditions on growth rate indices of cod are discussed in the light of these results.
