The present study was performed to analyze the infection status of trematode metacercariae in fishes caught from Chunamchosuchi (pond) located in Uichang-gun, Kyongsangnam-do. A total of 130 freshwater fish of 5 species was collected by a fish net and fish traps from November, 1995 to May, 1996. They were examined under a stereomicroscope after artificial digestion with pepsin-HCl solution. A total of 8 species of metacercaria, i.e. Clonorchis sinensis, Echinochasmus japonicus, Cyathocotyle orientalis, Diplostomum sp., Metorchis orientalis, Holostephanus nipponicus, Exorchis oviformis and unidentified echinostome, was detected from them. The metacercariae of C. sinenesis were found in 8/20 (40.0%) Acanthorhodeus asmussi, 20/20 (100%) Culter brevicauda, 31/45 (68.9) Cultriculus eigenmanni and 21/25 (84.0%) Pseudorasbora parva, and the average number of metacercariae detected in each fish species were 1.9, 31.7, 15.3, and 73.0. From the above results, it was confirmed that fresh-water fishes from Chunamchosuchi (pond) were highly infected with metacercariae of avian trematode, i.e. C. orientalis, H. nipponicus, M. orientalis, E. japonicus and Diplostomum sp., and 4 species of fish, P. parva, C. brevicauda, C. eigenmanni and A. asmussi, were infected with metacaecariae of C. sinensis.
本研究旨在分析庆尚南道蔚珍郡Chunamchosuchi(池塘)捕获的鱼类中吸虫囊蚴的感染状况。1995年11月至1996年5月,用鱼网和诱捕器共采集了5种130条淡水鱼。用胃蛋白酶-盐酸溶液人工消化后,在体视显微镜下对其进行检查。共检测到8种囊蚴,即华支睾吸虫、日本棘隙吸虫、东方杯叶吸虫、复口吸虫属、东方后睾吸虫、日本全冠吸虫、卵形前口吸虫和未鉴定的棘口吸虫。在8/20(40.0%)的黑鳍鳈、20/20(100%)的短尾鲌、31/45(68.9%)的陈氏短吻鱼和21/25(84.0%)的麦穗鱼中发现了华支睾吸虫囊蚴,每种鱼类检测到的囊蚴平均数量分别为1.9、31.7、15.3和73.0。根据上述结果,证实Chunamchosuchi(池塘)的淡水鱼受到禽吸虫囊蚴的高度感染,即东方杯叶吸虫、日本全冠吸虫、东方后睾吸虫、日本棘隙吸虫和复口吸虫属,并且4种鱼类,麦穗鱼、短尾鲌、陈氏短吻鱼和黑鳍鳈感染了华支睾吸虫囊蚴。
