A COMPARATIVE STUDY ON SEASONAL DISTRIBUTION OF THE HELMINTH PARASITES COMMUNITIES OF SOME CATFISHES
The present investigation was carried out seasonally from October 2008 to September 2010, to study the impact of helminth parasites of catfishes of Lucknow. The fish fauna viz., lessThan i greaterThan Clarias batrachus, Heteropneustes fossilis, Wallago attu, Mystus vittatus lessThan /i greaterThan and lessThan i greaterThan Rita rita lessThan /i greaterThan were carried trematode, cestode, nematode and acanthocephalan parasites communities singly or mixed. The collected fish species include two monogenean species ( lessThan i greaterThan Gyrodactylus lessThan /i greaterThan and lessThan i greaterThan Dactylogyrus lessThan /i greaterThan ), seven digenean species ( lessThan i greaterThan Clinistomum, Euclinostomum, Gastrohtylax, Paramphistomum, Opisthorchis, Aspidogaster lessThan /i greaterThan and lessThan i greaterThan Fasciola lessThan /i greaterThan ), one cestode species ( lessThan i greaterThan Teania lessThan /i greaterThan ), one nematode species ( lessThan i greaterThan Trichinella lessThan /i greaterThan ) and one acanthocephalan species ( lessThan i greaterThan Pallisentis lessThan /i greaterThan ). The data showed significant highest parasitic communities during the summer season, moderate in monsoon and lowest in winter season. The overall prevalence of helminth infection was 58.71 % in catfishes. Among helminth parasites communities, trematode parasites were found to be maximum in number than the rest three parasitic group i.e. cestode, nematode and acanthocephalan parasites. No clear pattern of association between helminth species was detected, showing an unstructured helminth community in which the occurrence of any species was not restricted or favored by the occurrence of any other species. The lack of association might be different life-cycles of parasites. With respect to helminth infection; maximum infection was recorded in case of lessThan i greaterThan Heteropneustes fossilis lessThan /i greaterThan and minimum infection intensity was detected in lessThan i greaterThan Rita rita lessThan /i greaterThan as compared with other catfishes. The aim of investigation based only to provide the information about fishes harbor the helminth parasites seasonally and avoid these fishes to consume in particular season.
