In fish, otoliths are continuously deposited elements with environmental information. This paper discusses the bioaccumulation level of essential and non-essential metals in water and otoliths samples of two threatened freshwater catfishes of genus Ompok collected from the Gomti river of Uttar Pradesh, India. The concentration level of trace metals (Ba, Sr, Zn, Mn) in otoliths and water samples differed considerably between sampling locations (p < 0.05) and a strong correlation exists on trace metals (r > 0.9) between otoliths and water samples. The occurrence of trace metal type and its concentration in otoliths proves the potential sites preferred for O. pabda and O. bimaculatus.
