Seasonal Changes In Biochemical Composition Of The Mangrove Oyster, Crassostrea Tulipa (Lamarck) Occurring In Two Coastal Water Bodies In Ghana


The meat condition and biochemical composition of the mangrove oyster, Crassostrea tulipa (Lamarck) were investigated in two water bodies on the coast of Ghana from May 1988 to April 1989. Both the lagoon and estuarine oysters maintained moderate to high condition for at least eight of the 12 months study period, but the lagoon oysters had a higher annual mean condition index. Protein, fat, carbohydrate and ash content of the Ghanaian oyster were comparable with those of other commercial bivalves elsewhere. The results also indicate that the local oyster could serve as a year round rich source of calcium, iron and phosphorus. It is concluded that the nutritional value of the species is high in both populations and that the lagoon could be a favoured site for large-scale cultivation.
