Condition index of Crassostrea madrasensis preston (Ostreoida, Ostreidae) and C. Gryphoides schlotheim (Ostreoida, Ostreidae) and its percentage edibility in populations associated with selected mangrove habitats from Goa, India.

Abstract

Oyster samples of Crassostrea madrasensis (Preston) and C. gryphoides (Schlotheim) were collected, on monthly basis, during the period from August 2005 to July 2006. Observations have revealed uncontrolled exploitation of oyster beds, which may lead to destruction of these beds. The optimum time for collection oysters found to be between February and May, when percentage edibility and condition index values are the highest. It is suggested that regulation of oyster collection is required for the sustainable development of oyster fisheries in Goa
