Copper Toxicity and Bioassay Studies on Freshwater Fish ?Cyprinus Carpio?

Copper is one of the most toxic heavy metal to fish and consumption of fish after copper treatment in water may pose a serious risk to human health. Fishes are generally used as pollution indicators in water quality management. The use of biological test system for monitoring pollution is gaining importance worldwide by employing toxicity test model Elevated levels of copper may become acutely or chronically toxic to aquatic lives. Chronic effects include reduced growth, shorter lifespan, reproductive problems, reduced fertility and behavioral changes.
