Helminth Infection in Freshwater Fishes of Bangladesh

Abstract

Edible freshwater fishes common in central, northern and southern parts of Bangladesh were examined to record their helminth infection. A total of 78 taxa of helminths-1 monogenean, 28 digeneans, 8 caryophyllid cestodes, 24 nematodes and 17 acanthocephalans were recovered from 7 different organs of 37 species of freshwater fishes. Two species of trematodes (Ophiocorchis dasus GUPTA and Coitocaecum sp.), eight species of caryophyllids (Lytocestus indicus (MOGHE) WOODLAND, Lytocestus birmanicus LYNSDALE, Lytocestus parvulus FURTADO, Bovienia serialis (BOVIEN) FUHRMANN, Djombangia penetrans BOVIEN, Lucknowia sp., Capigentoides batrachii GUPTA and Pseudocaryophyllaeus indica GUPTA) and twelve species of acanthocephalans (Neoechineorhynchus topseyi PODDER, Neoechinorhynchus sp., Acanthosentis dattai PODDER, Acanthosentis indicus TRIPATHI, Acanthosentis tilapiae BAYLIS, Pallisentis allahabadii AGRAWAL, Pallisentis sp. 2, Pallisentis sp. 1 Devendrosentis garuai SAHAY et al., Hypoechinorhynchus sp., Heterosentis plotosi YAMAGUTI and Mehrarhynchus secundum TRIPATHI) are reported for the first time from Bangladesh.Parasitic helminth incidence, infection intensity and distribution of the caryophyllid cestodes and acanthocephalans are also reported.
