Study of parasitic effect of Argulus sp. on Indian major carps in pond culture


Author(s): Priyanka Kumari and Dr. MMR Nomani

Abstract: The current investigation was undertaken to study the parasitic effects of Argulus sp. on Indian major carps. Only symptomatic and moribund samples of diseased fishes comprised of fingerlings and adults of Labeo rohita, Catla catla and Cirrhinus mrigala were collected for experiments. The affected fishes showed weight loss, retarded growth, restlessness, erratic swimming behaviour and loss of appetite. The skin showed abnormally pigmented while gills, kidney, liver and spleen of the affected fishes were pale in colour. The most significant histopathological lesions in the gills were the secondary lamellar hyperplasia, haemorrhages in the tips of the primary lamellae and fusion of both secondary and primary gill lamellae. Skin showed epidermis was lost but the epidermal cells in the vicinity of the sites of attachment were hyperplastic, muscular layer showed degenerative and necrotic. Kidney showed multifocal enlargement of glomeruli, glomerular tufts in many places shrunken, fragmented and necrosed, in renal tubules vacuolar degeneration. Fingerlings and adults of rohu were found highly susceptible to this disease than other IMC.
