Abstract

A study was undertaken to investigate suppression of ovarian development caused by endohelminthic parasites in three species of freshwater fishes viz., Channa punctata, Nandus nandus and Xenentodon cancila. Ovaries of host fishes were
primarily found infected with encapsulated larvae, indirectly affecting ovarian development. Lower gonadosomatic index and fecundity were recorded in infected fishes compared to uninfected ones. The study also assessed histopathological
changes caused by the parasites, which revealed damaged and disrupted germinal epithelium, damaged oocytes showing signs of necrosis, liquification of yolk globules and reduction in yolk formation in infected ovaries.
