Abstract:

Channa punctatus is one of the most delicious and demandable freshwater fishes of the country because of its high nutritional value, cheap cost and availability in the local markets. These fishes are often infected by parasites, which decrease the rate of growth as well as the reproduction rate of the host fishes, resulting in deteriorating the food value of fishes and economic loss to the culturists. Study of parasites is therefore an urgent necessity today. The prevalence of parasites in Channa punctatus was studied from different regions of Rajshahi Metropolis during July 2013 to April 2014. A total of 368 parasites were collected from the skin, gill, fin, intestine and stomach of 74 host species from 102 experimental fishes. Ten different parasitic genera were identified, among them six were ectoparasites and four endoparasites. Of ectoparasites, three were protozoan viz., Trichodina pediculatus, Ichthyophthirius multifiliis, and Myxobolus sp., two monogenetic viz., Dactylogyrus vastator and Gyrodactylus elegans and one crustacean viz., Argulus species. Among endoparasites, one nematode viz., Camallanus sp., two trematodes viz., Eucreadium sp., Genarchopsis sp. and one acanthocephalan viz., Pallisentis sp. were recorded. Organ-wise distribution, monthly, seasonally, sex and length-wise fluctuations of prevalence, abundance and mean intensity of the parasites were studied. The highest level of infestation was observed in host skin, while lowest levels were observed in host stomach. The results also revealed that the intensity of parasitic infestation in different organs of C. punctatus varied with the season. In particular, the highest levels of infestation were recorded during the autumn (October-November), when the fishes are most susceptible to parasites and the lowest number was recorded in the rainy season. Prevalence of infection of parasites is very considerably depending on seasonality, environmental conditions and management practices.
