Epidemiology of Diplostomum in the Eyes of Esoxlucius in the Ergis River
摘要
Abstract
Esoxlucius is a carnivorous fish species native to the Ergis River.Delicious and highly nutritious,it has become an important artificial breeding species since the Xinjiang native fishery has developed.Recent research shows that Diplostomum is a common parasite of fish in the Ergis River and the large scale,high density culture of Esoxlucius increases the risk of parasitic infection.Many species have been recorded with high prevalence and in-fection intensity and it is seriously affecting aquaculture and fishery resources in the Ergis River basin.This paper characterized the epidemiology of Diplostomum in the eyes of Esoxlucius in the Ergis River,aiming to provide basic information for the prevention and treatment of disease in artificially cultured Esoxlucius.The study is based on the analysis of 263 Esoxlucius specimens collected in the Ergis River basin from April 2009 to July 2014.The speci-mens were classified into five groups according to body length:L≤20 cm,20 cm<L≤30 cm,30 cm<L≤40 cm, 40 cm<L≤50 cm,L>50 cm.Diplostomum infection in the eyes was recorded after autopsy and the spatial and frequency distribution of Diplostomum infection was analyzed for each group.Results show that Diplostomum is par-asitic in Esoxlucius all through the year and prevalence increases from spring to winter.The highest infection inten-sity was also in winter,then summer,and the lowest infection intensity was in spring and autumn.The total preva-lence of Diplostomum was 34.98%and mean infection intensity was 10.74.The mean prevalence and infection in-tensity increased with the host body length increase,but the infection rate was the lowest in the body length>50 cm(4.17%).The ratio of standard variance to average was>1 for all body length groups,suggesting that the population of Diplostomum exhibits an aggregation distribution in Esoxlucius and the aggregation intensity increases with host size.关键词
