Seasonal energy changes in mature and immature cod of the same size were studied. For most ofthe year, the variations in energy content iathe tissues ofboth mature and immature cod are similar. In the period from October to January, the fish accumulate energy. From January until spawning in early April there is a fall in the total energy content. The growth of gonads from January until spawning can explain about one-third of the energy decrease in liver and muscle.
