Objective: The main objective of this study is to reduce the lead induced toxicity in Labeo rohita using Hydrilla verticillata supplemented with normal fish food.

Methods: The fish were divided into three groups by treating with sublethal concentration of lead and feeding normal fish food, fish food supplemented with hydrilla dry powder and control fish without lead. After 21 days, the gill and liver tissue samples were collected and histological analysis was carried out.

Results: The histology of gill and liver of lead acetate induced toxicity against normal fish feed showed swollen gill, degeneration of lamella and hepatocytes and formation of cytoplasmic vacuoles. On the other hand, the histological changes were minimized in lead acetate induced toxicity against fish food supplemented with hydrilla and expressed apparently normal architecture.

Conclusion: Hence, it is proved that Hydrilla verticillata may be a very good keystone species to reduce lead toxicity in Labeo rohita.
