Cultivated fishes are major protein and microelement sources for all sorts of people in Bangladesh due to its availability and affordability. Essential metals are persistent in the environment and are subject to bioaccumulation in the food chain. Fish is at the top of the aquatic food chain and normal metabolism of ﬁsh may accumulate large amounts of different essential metals from water, food or sediment. This study was carried out to determine essential metal concentrations in the flesh of some cultivated fish species and commercial fish feeds available in Bangladesh. The essential metal concentration in fish and consumed fish feed were assessed by Inductive Coupled Plasma Optical Emission Spectroscopy (ICP-OES) with significant variation (P < 0.05). The concentration (mg/kg - dry weight) of Fe, Cu, Zn, Na, K, and Ca were observed 23.33 - 63.3, 12.80 - 20.62, 10.00 - 26.25, 214.2 - 367.68, 285.71 - 485.71, 256.89 - 432.65 in selected commercial fish feeds whereas those were found 33.33 - 80.83, 14.00 - 31.80, 20.60 - 49.25, 250.98 - 500.78, 400.76 - 587.32, 408.16 - 857.14 in cultivated fish species. All analyzed metal concentrations were within the acceptable of World Health Organization (WHO, 2004), Food and Agricultural organization (FAO, 2004), European Union (EU, 2010) and US Environmental Protection Agency (USEPA, 2011) and Total Hazardous Quotient (THQs) value of all the selected metals were lower than 1, which suggesting no remarkable non - carcinogenic health hazards for adult population.
