Seasonal changes in the body component indexes of Littorina irrorata were studied for a two year period. Biochemical constituents (protein, carbohydrates, and lipids) in the soft body components were analyzed for one year. Body component indexes cycled seasonally. Shell index changes may be due to the seasonal changes in the total of other indexes. All soft body components, except the foot, exhibited a seasonal cycle which was correlated with the reproductive cycle. Female Littorina irrorata appeared to exhibit a bimodal pattern of capsule deposition with the two peaks occurring in May and August. Seasonal changes in the biochemical level and …
