Trace heavy metals (Cd, Zn, Ni, Cu, Pb and Co) were determined in Penaeus notalis, Macrobrachium vollenhovenii, Palaenon sp. and Procambaris clarkii obtained from coastal water of Ondo State, Nigeria using atomic absorption spectrophotometry. Co and Ni were higher in the water sample than in the prawn samples, while Pb and Zn were the most abundant metals in Palaenon sp. than other samples. Cd was not detected in all the samples. The highest correlation was found between Ni and Pb. Pb and Zn showed the highest levels of bioconcentration factor of 1.27, respectively in P. sp. The physical parameters of the water in sample were within the recommended standards for aquaculture. Concentrations of metals in the sample were found to be low and the levels do not pose a health hazard for consumers. Regular monitoring of the costal water is recommended.
