摘要：

The aim of this study was to verify the yield of hatchery produced seeds of the mangrove oyster Crassostrea gasar cultivated, from May to July (2008), in a floating boxes system at two locations (48 degrees 32'W - 27 degrees 29'S, Sambaqui - Floriano polis and 48 degrees 50'W - 26 degrees 28'S, Iperoba - Sao Francisco do Sul). Management with pressured freshwater was performed weekly and four standardized sifting was done twice a month. At each sifting, the volume of seeds was calculated, as well as quantified by size. The results have shown the yield of 95.3% in Sambaqui and 58.7% in Iperoba, after nine weeks of cultivation and four siftings. Management techniques of seed used for Crassostrea gigas have proven to be efficient for the native species C. gasar. Both locations can be considered appropriate for the step of growing seeds.
