The present investigation was carried out in pathological and histological alteration findings from acute and chronic infection in Labeo rohita naturally infected with Argulus. Fish samples were obtained from fish farmers of Kamrup district of Assam. The clinical signs in infested adult fish were lethargy, anorexia, poor growth, erratic swimming and mortality. Histological study revealed marked alterations in liver and kidney tissues in comparison to normal architectures observed in control fish. Degeneration of blood vessels, hypertrophy, increased pyknotic nuclei and lesions were observed in liver. In the kidney, shrinkage of the glomerulus, and hyaline degradation were observed. These results can suggest that histopathological variations influenced by the Argulus foliaceus in Labeo rohita can act as a susceptible to diseases, a potential threat to fish farmers and lead to economic loss.
