Abstract:
The present study was conducted on the host fish named Oreochromis niloticus(Linnaeus, 1758) of the family Cichlidae. A total of 42 host fishes of the same species was collected from the two different locations, Pagla Lagoon at Narayanganj and Tongi Hatchery at Gazipur. The host was identified and separated into two groups of males and females. Host fishes were divided into five length groups and eight weight groups according to their length and weight respectively. The female hosts were observed to be more infested than the males. The parasitic infestation, prevalence and intensity of host fishes in Tongi hatchery were observed higher than the host fishes of Pagla lagoon. A total of sixty one and one hundred and twenty three parasites were recovered from a host of Pagla lagoon and Tongi respectively. Each parasite was examined for taxonomic identification. A total of seven parasites were identified from three taxonomic groups. Trematodes: Allocreadium mahaseri (Pande, 1938), Clinostomum piscidium (Southwell.et. Prashad, 1918), Lecithochiriuum sp. (Liihe, 1900), Opegasterditrematis (Yamaguti, 1942). Nematodes: Gnatho stoma spinigerum (Owen, 1836), Porrocaecum sp. (Rallict. et. Henry, 1912). Acanthocephala: Pallisentis nandai (Sarker, 1953).Allocreadium mahaseri,Gnathostoma spinigerum and Porrocaecumsp parasitic species affected commonly the host fishes of both water bodies. Only one acanthocephalan, Pallisentis Nanda was collected from Tongi hatchery and one trematode Lecithochiriuum sp. from Pagla Lagoon.
