Abstract: Bioaccumulation of heavy metals (Zn, Pb, Cd, and Cu) was determined in the liver, gills, and fesh from benthic and pelagic fsh species collected from Lake Geriyo covering two seasons. Te levels of the heavy metals varied signifcantly among fsh species and organs. Flesh possessed the lowest concentration of all the metals. Liver was the target organ for Zn, Cu, and Pb accumulations. Cd however exhibited higher concentration in the gills. Fish species showed interspecifc variation of metals. Tese diferences were discussed for the contribution of potential factors that afected metals uptake like age, geographical distribution, and species-specifc factors. Te concentration of metals in fsh fesh was accepted by the international legislation limits for Cu, Zn, and Cd; however, Pb transcend in Clarias and Tilapia during wet season and Heterotis in both seasons, hence unsafe for human consumption and a threat to public health. Tese levels might be due to anthropogenic inputs as there is no industrial activity around the lake.
