A study was made of the effect of day length and feeding-time on the smolting process and on growth of Atlantic salmon during smolting. The experiment consisted of five experimental groups with different day lengths. Highest growth rate and most seawater adapted fishes were found at the longest photoperiod, 24 hours of daylight and lowest growth rate and number of seawater adapted fishes were found at the shortest photoperiod, simulated natural photoperiod for Bergen.
