Reproductive and patho-physiological responses of blue tilapia (Oreochromis aureus) exposed to chromium with or without chelating substances

Abstract

Water pollution with chromium included significant negative impact in the hematological and biochemical parameters together with marked histopathological alteration and lowering reproductive performance of fish. The addition some chelating agents (EDTA, super phosohate and charcoal) could decrease this degree of toxic effects of chromium and improve the fish condition.
