Abstract
The population of Venerupis pullastra at just below MLWS had a mean density of 31.0 individuals per ¼ m2 in both 1968 and 1969. The following ratios were calculated: length/total weight, length/shell weight, length/weight of soft parts, and shell weight/weight of soft parts. The dry weight of soft parts was 19.66 %, and the ash content 2.65 % of the wet weight. The potential production of the population was 20 g ash-free dry weight/year per m2, including a loss of 9 g due to mortality.
