Fifteen-day pediveliger larvae of Anadara grandis (shell length, 230 ± 20 µm (mean ± SD, n = 20) were cultivated up to the juvenile stage by testing 2 densities: 71 larvae/cm² and 283 larvae/cm² for 37 days. During this time, we registered morphological changes of the larvae from pediveliger up to the juvenile stage, as well as absolute growth, and growth and survival rates. The growth rate was 53.5 µm/day at a density of 71 larvae/cm², with a survival of 60%; at a density of 283 larvae/cm², the growth rate was 33.6 µm/day, with a survival of 40%. Subsequently, the juveniles obtained were nursed for 57 days in 2 types of experimental units: Nestier trays suspended in a pond and cylindrical upwelling containers with increasing water flow in the laboratory. In each experimental unit we cultured 66,666 juveniles with a shell length of 1.57 ± 0.05 mm (n = 20). In the Nestier trays, growth was 4–6 µm/day, with a survival of 15%. In the upwelling-type units, growth was 5–6 µm/day, with a survival of 93%. ANOVA revealed significant differences (P < 0.05) in juvenile growth between the Nestier trays and the upwelling-type containers. Low juvenile survival in Nestier trays is attributed to clogging with wind-blown slime. However, a nursery of A. grandis juveniles in ponds requires further research to show its economic feasibility.
