Proximate Composition and Mineral Contents of the Flesh and Shell of Tympanotonus Fuscatus (Linnaeus, 1758) (Gastropoda: Potamididae) of the Cross River, Nigeria

Tympanotonus fuscatus var .radula (L) is a species of periwinkle living in the black mud of the mangrove swamp forest along the brackish water mangrove swamp forest area of the West Africa rivers and in the Cross river in Nigeria. The proximate and mineral contents of it flesh and shell were investigated using techniques recommended by AOAC. The moisture, crude protein, ash, fat contents of the flesh were 50.00 mg/100gm, 22.32mg/100gm, 1.22 mg/100gm, and 10.02 mg/100gm respectively. The respective values of 20.05 mg/100gm, 2.63 mg/100gm, 8.1 mg/100gm and 0.3mg/100gm were determined in the shell. Energy values of 245.17 Kcal and 294 Kcal were measured from the flesh and shell of the species. Carbohydrate in the flesh was 16.42 mg/100gm while 68.41 mg/100gm was measured in the shell. Minerals ranged from 66.47 mg for calcium, phosphorus 13.5 mg for shell and 33.27 mg and 6.82mg in the flesh. Mineral concentrations were high in the shell than in the flesh
