Abstract
The triplicate experiment had been conducted in 50 m plots randomly placed in the intertidal areas to evaluate the effects of stocking biomass on survival growth performance and quality of clam Meretrix lyrata. The two stocking sizes (Mean SD cm) at shell length of 1.0 0.2 and 1.7 0.1 were scattered at different biomass: 0.05 0.1 0.2 0.3 kg.m-and 0.34 0.68 1.36 2.03 kg.m-and named as T1 T2 T3 T4 and T5 T6 T7 T8 respectively. Results show that meat ratio of the clam were similar regardless of different stocking biomass. The fatty acids were rich in highly unsaturated fatty acids especially docosahexaenoic acid but were variable. In contrast growth and survival of the clam were strongly affected by the stocking biomass in which the lower stocking biomass resulted in higher specific growth rate (SGR) and survival rate. The biomass gained therefore reduced accordingly with increase in the stocking biomass although the increase of final production was evident. However SGR and survival of the treatments T1 T2 and T3 were not significantly different suggesting the highest net profit and investment return of the treatment T3. Therefore the stocking biomass of 0.2 kg m was recommended to maximize profit of the clam cultivation.
