Abstract: Pollutants are known to induce biochemical changes in fish before the more drastic cellular and systemic dysfunctions are observed. Therefore, monitoring can be effectively used to detect such an affliction at an early stage of exposure. The blood often shows pathological changes before the external signs of poisoning can be seen. Hence, it is inferred that hematological studies in fish could be utilized as tools for investigating changes caused by environmental pollutants. The present investigation was carried out to study the effect of copper, lead and cadmium on some hematological parameters like TEC, PCV, Hb and TLC in the air breathing freshwater fish Heteropneustes fossilis (Bloch). All the parameters showed a considerable decrease except TLC. The duration of exposure didn’t show much variation. The sub-lethal compounds used were effective in the order Copper sulphate>Lead acetate>Cadmium chloride.
Keywords: Pollutant, Hematological, TEC, PCV, TLC.
