Contamination of aquatic ecosystems with heavy metals has become a global problem and the impact of them on aquatic environments is severe due to the inability of water to disperse contaminants. To meet this threat, ecotoxicologists face a difficult challenge on how to assess the long-term impacts of metals which have already been released into the environment. Biomarkers indicate molecular and biochemical responses in exposed individuals as a tool to assess the status of an impacted environment and they can also serve as a basis for a Rapid Risk Assessment of Fish Health. In this context, this study evaluated three biomarkers (metallothionein (MT), Na+K+ ATPase and heat shock/stress protein 70 (HSP 70)) to determine the integrated physiological responses in Oreochromis mossambicus to one metal (copper (Cu)) at a sub lethal level over the short term. The information gained from these tests was valuable in suggesting what the baseline levels of biomarkers in O....
