Stocking density was 1 spat per 6, 13, and 19 square m with 3 replicates. Average initial spat size was 3 cm. Growth and survival were checked once a month. Oyster spat were cleaned and water quality determined every two weeks. The growth of oyster spat in terms of length and width was not different (P0.05) for all stocking densities. But, the survival rates were significantly different (P0.05) between stocking densities of 1 spat per 6 square cm and 1 spat per 19 square cm. A stocking density of 1 spat per 6 square cm had the highest initial cost but gave the highest return per crop.
