Description :
Examination of freshwater fishes from Ekburgi reservoir in Washim region of Maharashtra revealed the presence of
Myxosporean species of the genus Henneguya Thelohan, 1892, on gill surface of cultured freshwater fishes. The
Henneguya species reported during the present research is Henneguya notopteridae Quadri,1965 with heavy
infection on gill surface and kidney of freshwater fishes Catlacatla, Labeo rohita and Notopterus notopterus. The
present research emphasizes the morphometrix of Henneguya notopteridae parasite together with
histopathological impact on fish. Henneguya notopteridae infected fish exhibits haemorrhagic condition with
necrotic changes in the epithelia and connective tissue of gills. Pronounced inflammation has been observed
leading to structural disorganization of secondary lamellae. Nearly complete loss of respiratory function,
accompanies infection.
