STUDY ON THE EFFECT OF COPPER ON TOXICITY OF FRESH WATER FISH

Abstract

Freshwater ecosystems play a crucial role in maintaining biodiversity, supporting fisheries, and providing essential services to human communities. However, these ecosystems face increasing threats from various pollutants, including heavy metals like copper. This study investigates the impact of copper on the toxicity of freshwater fish, aiming to understand the ecological and physiological consequences of copper exposure.

The research focused on a comprehensive assessment of copper toxicity by conducting controlled experiments involving a specific freshwater fish species. A series of acute and chronic exposure experiments were conducted, with fish exposed to varying copper concentrations. The effects of copper were evaluated through observations of fish mortality, growth parameters, and physiological responses. The findings revealed a clear dose-response relationship between copper concentrations and fish mortality, with higher copper levels leading to increased mortality rates. Chronic exposure to copper also resulted in reduced fish growth, indicating its adverse impact on fish health and population dynamics.

This study provides valuable insights into the complex interactions between copper and freshwater fish, emphasizing the importance of addressing copper pollution to protect the integrity of freshwater ecosystems and the well-being of both aquatic life and human communities dependent on them
