Histological effect of monogenean parasites on gills of freshwater carps
Pinky Kaur and Rekha Shrivastav
Present investigation was carried out to study the histological effect of monogenetic parasite (Paradactylogyrus sp. and Dactylogyrus sp.) on gills of freshwater cultivable carps. During present investigation Labeo rohita andHypophthalmichthys moltrix were collected from eutrophic lakes (Lower Lake and Mansarovar Lake) of Bhopal region. Maximum prevalence was exhibited byLabeo rohita (20.0%) and least prevalence is recorded in H. molitrix (12.8%). Histological analysis revealed that the gills of H. molitrix was greatly affected which may be due to multiple infection by unidentified protozoan andDactylogyrus sp. The pathological changes includes upliftment of respiratory epithelial layer, damaged cartilaginous core, deshaped secondary gill lamellae and damaged pillar cells.
