Author(s): Shivali Singh and Pinky Kaur
Abstract: The present study was conducted to reveal a histological analysis on the gills of Labeo rohita and Hypophthalmichthys molitrix specimens were observed to reveal the histo-pathological characteristics of the gills of these freshwater carps. The histological examination of the gills of Labeo rohita revealed the proliferation of bronchial tips, shortening and fusion of secondary gill lamellae, desquamation of primary and secondary gill lamellar epithelium, uplifting of respiratory epithelial wall and damaged pillar cells due to monogenetic parasites. Whereas drastic disorganization was observed to be caused due to multiple infestation by protozoan and copepod in gills of Hypophthalmichthys molitrix characterized by revealed the proliferation of bronchial tips, shortening, thinning and deshaping of gill lamellae’s.
