Seasonal changes in biochemical composition of the bivalve Nucula sulcata from the Clyde Sea Area

Seasonal changes in the body weight and composition of Nucula sulcata Bronn from south of Little Cumbrae Island in the Clyde Sea Area (UK) were studied during the period August, 1969 to April, 1971. The composition of an animal of standard size was calculated for each sampling date to give information on seasonal changes independent of shell growth. Increase in body-tissue weight took place between May and October as the gonad developed and as reserves were built up. Spawning in the population took place in November, resulting in a rapid fall in body weight, and an increase in tissue water-content. These processes were less well defined in 1970 than in 1969, but the same general pattern was followed in both years. Ripe males showed a consistently higher tissue weight than females, but the female gonad contained significantly greater quantities of lipid. The changes are compared with those for other bivalves from the same general area.
