Abstract
Yellow grub disease is yellow grub metacercriae caused by parasites in the fish. Clinostomum complanatum is a trematodes, life cycle need to switch to a different host, and the host specificity is low. If humans eating contaminated fish will have the opportunity to suffer symptoms caused by clinostomum pharyngitis. This study from 102 March to 103 April, will to research for yellow grub disease in Tahan River basin.
In 1,503 fish samples, a total of 141 to be infected; which San Min River had most serious infection (prevalence 31.7%), followed by Nan Zu Gou River (prevalence 20.5%), the Hou Tse Yen Downstream (2.03%). She Wu Nau River and Shihmen Reservoir alone did not detect the yellow grub disease. In infected fishs, most serious is A. paradoxus, Z. barbata, Z. pachycephalus and Z. platypus. More than 80% parasites found in oral cavity, under mouth, opercle, muscle, caudal fin. Infection have no difference between the month.
The monitoring results found that 162 samples of freshwater snails, only one R. swinhoei release cercaria of C. complanatum. Not detected by molecular biological detection C. complanatum DNA.
The results show that the Tahan River basin with C. complanatum required to complete the life cycle of the host, so the C. complanatum has been prevailing in Tahan River basin. Shimen Reservoir is an important tourist places, so consumers should be careful to eat fish.
