Nutrient values of the oyster Saccostrea cucullata were studied in 3 different stations in the Iranian shores of the Oman Sea, Beris, Chabahar and Tang. Specimens were taken monthly during summer ]999. Water. ash, protein, amino acids, T.V.N and fat contents were measured using standard methods. Highest water content was measured 78.34 percent for Beris specimens. it was 77.95 and 78.10 percent for Tang and Chabahar specimens, respectively. Chabahar oysters had highest ash content of 3.16 percent in comparison to 2.73 and 2.5 percent for Tang and Beris respectively. Highest protein content was measured 16.26 percent for Chabahar specimens, while it was 15.45 and 15.42 percent for Beris and Tang specimens , respectively. Chabahar specimens had also highest measured T.V.N , 5.6 mg/g , compared to 2.8 mg /g for Beris and Tang specimens. Chabahar specimens were richest in fat content with 0.8 percent compared to 0.72 and 0.64 percent for Tang and Beris specimens.
