Seasonal variation in the proximate composition of rock oyster Saccostrea cucullata from Bombay coast

Changes in proximate composition of soft tissue of rock oyster Saccostrea cucullata inhabiting a polluted station at Bandra (stn. B) and a relatively clean area at Mudh Island (stn. M) were studied. An average protein content of 48.88 plus or minus 3.73 and 53.68 plus or minus 3.59% were recorded respectively for oysters from stns. M and B and the difference was significant. Mean carbohydrate content in oysters from stn. M amounted to 14.69 plus or minus 3.22 whereas at stn. B it was 8.70 plus or minus 1.61 and the difference was found highly significant. However, appreciable variation between stations was not observed in lipid and carbon content in oysters. Suitable periods for harvesting of these organisms are suggested.
