Abstract :

A histopathological studies was carried out to investigate the influence of monogeneanparasite (Diplozoonparadoxum(Nordmann, 1832)irritation on the gills of fresh water fish Osteoamavigorssiiform Nira river Bhordistrict,(Maharashtra), India.Osteoamavigorssii is endemic to Western Ghats of Maharashtra and is commonly consumed by local population in fresh form as well as dried and preserved form. Histopathology provides a rapid method to detect effects of irritants and pathogens in gills and it can be considered as theindicator for abnormal condition for fish environment. The collected fish specimenswere subjected to full clinical, parasitological and histopathological examinations. The histopathological alterations due to diplodocus paradox parasitic lead to hyperplasiafollowed by complete sloughing of secondary gill lamellae,the infected fish gills showed pathological alterations such as proliferative, necrotic as well as degenerative changes in the epithelium of gill filaments.Aneurism in secondary lamella was clearly seen.The cartilaginous tissues of gill filaments displayed severe proliferation causing deformity and thickening of gill filaments.
