Crecimiento y sobre vivencia de semillas del ostión <i>Crassostrea virginica</i> en una granja camaronícola en Yucatán, México

Abstract

A lot of 1600 seeds of American oyster Crassostrea virginica from the coastal lagoon La Redonda, Tabasco, Mexico was cultured in main drainage channel (S1), a secondary drainage ehannel (S2), the floodgate of a white shrimp Pennaeus vannamei pond (S3) and the marine water supply pond (S4). The seeds, with a total height and initial humid weight of 31.67±3.43 mm and 4.29±1.32 g, respectively, were cultured in suspended Nestier oyster boxes at 575 org/m2. Biological and environmental parameters were recorded after 296 days, the seeds in S4 reached height and weight values of 52.55±7.51 mm and 16.30±4.94 g, respectively. The index of physiologic condition along the experiment had a variation of 1.26% to 3.45%. In S4 the survival was 81.0%. In the. other places the mortality was total after 90 days.
