Abstract

The food and mineral contents of flesh of the two bivalve species (Egeria radiata and Crassostrea rhizophorea) of Cross river, Nigeria were investigated. The study revealed that the moisture content of E. radiata and C. rhizophorea was 52.46% and 54.01%, crude protein was 24.37% and 20.49%, fat was 9.03% and14.22%, crude fibre was 0.01% and 1.30%, ash was 1.43% and 9.05%, carbohydrate was 12.7% and 2.23% and energy was 229.58J and 218.84J. The mineral content of E. radiata and C. rhizophorea  showed a significant difference (P<0.05) in Ca+, Na+, K, Mg, while the Zn, Pb, Cu, Fe, P and Mn were similar (P>0.05). Based on the findings of this study, biochemical profile of E. radiata is high in nutrients and is suitable for human consumption. Therefore, concerted efforts should be made to enlighten the populace on the increased nutritional benefits of consuming E. radiata.
