This study was undertaken to determine the proximate and mineral composition of Pelusios castaneus (West African-mud turtle) so as to contribute to the availability of data in Nigeria. A total of thirteen (13) male and female each of African mud turtle (Pelusios casteneus) were purchased in Benin City, Nigeria. Specimen were identified to species level, stunned and slaughtered; then each of the turtle were dissected into flanges and Microwave digestion system (Closed Vessels Acid Digestion – MARS System - CEM) procedure was used for the digestion of all the samples based on organic extraction technique before the proximate composition and the mineral contents of the flesh were determined using AOAC methods and standard technique. Data were analyzed using SPSS (version 21) and statistically using ANOVA and DMRT. Result shows that there were significant variations in the different parameters studied; the highest and lowest moisture content values of 67.00% and 52.56% were observed in the male and female respectively. Highest crude protein and lipid values of 26.78% and 15.00%, were observed in the female respectively; while the highest ash content value of 11.33% was observed in the male. While the mean mineral concentrations in the flesh varied among the different elements studied, the overall potassium had the highest value of 4030.82mg while the least value was observed in magnesium (871.04mg). Though Pelusios castaneus has been culturally important to Nigerians, the finding shows that the flesh is a valuable source of mineral elements and proximate components required in diet. Domestication in Nigeria is therefore encouraged to make them commercially available to reduce the pressure on their harvest from the wild thus preventing their going into extinction.
