| Abstract |
Growth and production of a population of the tropical clam Donax denticulatus, and important Venezuelan fishery resource, were studied for 24 months. Growth rates were 4,22 mm per month during the first 2-3 months post recruitment, 1 mm during the next 4 months and negligible thereafter. Mean maximal total length was 19 mm. Daily production ranged from 31-466 mg per m2 with standing dry weight biomasses of 4 to 40 g per m2. P/B ratios ranged from 0.005 to 0.016 per day. Daily production rates were used to calculate annual production of 37.6 g (181 kcal) and 77.4 g (372 kcal) m-2, respectively, for 1974-75 and 1975-76. |
