Crecimiento y sobrevivencia de la ostra perlífera (Pteria sterna) en cultivo suspendido flotante en la desembocadura del estuario del río Chone, provincia de Manabí

Abstract

The present study of growth and survival in phase of juvenile, during three months to different densities, were carried out with the purpose of finding the best conditions required for the development of the extensive cultivation of the oyster perlífera (Pteria sterna). The wild seed was captured in natural banks in the estuary of the river Chone in the month of November 2007, the juvenile ones that presented sizes initial average in longitude of the shell 50,18 mm, were placed in plastic egg pale and these on baskets of use fruit to densities of 50, 75 and 100 individuals for unit and they stayed in suspension to a depth of 2,25 m. The analysis of variance the cultivated organisms to the different densities, indicated significant differences. ( =0.05) among the longitude average to densities of 50 with 75, 50 with 100, 75 with 100. Differences were observed at growth, height and longitude of the shell, among the three densities under test.
