The edible flesh of guinean tilapia (Tilapia guineensis), blackchin tilapia (Sarotherondon melanotheron) and mullet (Liza falcipinnis) were collected from Choba river for elemental studies of cadmium, mercury, arsenic, lead, nickel and speciated forms of elements using X-ray fluorescence (XRF) and Gas chromatography-mass spectrometer (GC-MS) respectively. The highest concentration of cadmium (4.3mg/kg) was observed in Sarotherodon melanotheron. They all contained about the same concentration of arsenic (0.5mg/kg) and mercury (1mg/kg). The highest concentration of lead was detected in mullet (1.7mg/kg) while the highest concentration of nickel (7.3mg/kg) was detected in Sarotherodon melanotheron. The organometallic compounds detected were nickel tetracarbonyl, borane carbonyl in Tilapia guineensis, nickel tetracarbonyl, borane carbonyl and germanium(iv) pthalocyanine dichloride in Sarotherodon melanotheron and [µ-(ƞ6-benzene)]bis(ƞ5-2,4-cyclopentadien-yl)di-µ-hydrodi-vanadium and borane carbonyl in mullet
