The body weight of 0 year individuals of the limpet CoUiseUa heroldi increased throughout the year, while that of the over 1 year adults changed distinctly in accordance with its reproductive cycle.Somatic tissues of the adults showed decrease during the developmental period of the gonads, fast increment after spawning (October-December), and almost no growth during winter.Changes in the energy content of the somatic tissues also showed a reverse relationship with the gonads.Energy allocated to somatic storage declines with age from 90% to 35% for 0-5 year old animals while energy transferred to gonads increases with age from 5% to 64%.The energy transferred to the shell varied from 5% to 1% according to age from 0 to 5 year.Mean annual productions during the study period were 4.74 and 1.12 Cal/m2 for Pr and Pg, respectively.The mean P / B turn-over rate was 1.67.
