In recent years,serious epidemic caused by parasites had occurred in the west part of the Pearl Rivers,which had caused great damage on cage farming,and fish in the natural resources.The parasites had been preliminarily identified,belonging to Crustacea,Isopoda,Aegidae,RocinelaLeach.They were the newly found freshwater fish parasites in China.The authorused Rocinela sp.to carry on the study on parasitic behaviors to Cirrhina mrigala.The main results were summarized as follows: The parasites had very strong parasitic ability,the cumulative infection ratewas 90% in 240 min.The parasites had certain preferencefor parasitic locations of host fish,the gills ranked first(55.5%),followed by the bases of pectoral fins(25.9%).The parasites had strong lethal effects on host fish,after parasitized 23 h,thecumulativemortality was 16.7%.After the parasites sucked the blood of host fish,their length(L) was significantly higher than before,but their width(W) had no significant differences.Some parasites actively left the host fish,whose values of L and L/W increased significantly,the increment rates(%)were significantly higher than that of the parasites left passively,which caused Cirrhina mrigala died(P<0.05).There were some parasites that didn't leave host fish,but the scope of increment rates(%) of L and L/Wwas very big since the each different ingestion.

珠江水系西江的局部支流近年出现了严重危害网箱养殖和江河鱼类资源的寄生虫病害,初步鉴定该虫隶属于甲壳纲、等足目、鳃虫科、细角鳃虫属(RocinelaLeach),是国内新发现的淡水鱼类寄生虫。文章就该虫对麦鲮的寄生行为进行了研究,结果表明:该虫具很强的寄生能力,240 min内累积感染率达90%。对寄生部位具一定的选择性,以寄生在鳃腔比例最大(55.5%),胸鳍基部(25.9%)次之。对麦鲮具较强的致死效应,23 h的累积死亡率为16.7%。吸血后体长(L)显著增长,而体宽(W)基本无变化。从寄主身上主动脱落的虫体,其L和L/W的增值比(%)均显著高于因使寄主致死而被动脱落的虫体(P<0.05);而仍在寄主身上的虫体,其L和L/W的增值比(%)则因各自摄食量的不同而存在较大差异。

In recent years,a serious disease caused by a big parasite has occurred in Hejiang River of the Pearl River System,which has caused great harm to cage farming and natural fish resources.The parasitehas been preliminarily identified as Crustacea,Isopoda,Aegidae,Rocinela Leach and it was a newly found parasite of freshwater fish in China.This article reported the artificial infection with this parasite on grass carp(Ctenopharyngodon idella),giebel carp(Carassius auratus gibelio),and mrigal(Cirrhina mrigala).The...

In recent years,a serious disease caused by a big parasite has occurred in Hejiang River of the Pearl River System,which has caused great harm to cage farming and natural fish resources.The parasitehas been preliminarily identified as Crustacea,Isopoda,Aegidae,Rocinela Leach and it was a newly found parasite of freshwater fish in China.This article reported the artificial infection with this parasite on grass carp(Ctenopharyngodon idella),giebel carp(Carassius auratus gibelio),and mrigal(Cirrhina mrigala).The results showed that this parasite had very strong parasitic ability,the cumulative infection rate was 76.2% ~ 100.0%.It had certain preference for parasitic sites,the gill ranked first(55.6% ~ 72.0%),followed by the pectoral fin(11.7% ~ 28.8%).The parasite also showed strong lethality in the tested fish.After sucking blood,the parasite had a higher increase of body length(L),while it almost had no changes in body width(W).The L/W of the parasites which left the hosts initiatively had higher increase rate(16.32% ~ 18.00%),while the L/W of those that stayed on the hosts all the time increased differently depending on the differences of individual feed intake.

珠江水系贺江段近年出现严重危害网箱养殖和江河鱼类资源的大型寄生虫病害,初步鉴定该虫隶属于甲壳纲,等足目,鳃虫科,细角鳃虫属,是国内新发现的淡水鱼类寄生虫。用该虫对草鱼、银鲫、麦鲮进行人工感染,结果表明:该虫具有很强的寄生能力,累积感染率为76.2%~100.0%;对寄生部位具有一定的选择性,以寄生在鳃部的比例(55.6%~72.0%)最大,胸鳍(11.7%~28.8%)次之;对试验鱼有较强的致死性;该虫吸血后体长(L)增长较大,体宽(W)基本不变;从寄主体上主动脱落的虫体,其L/W的增长率(16.32%~18.00%)较大,而一直寄生在寄主身上的虫体,其L/W的增长率则因各自摄食量的不同而存在较大的差异。
