琴湖江 참붕어에서의 肝吸蟲 被囊幼蟲 寄生狀의 變動 = Recent Change in Infestation Pattern of Clonorchis sinensis Metacercariae in Peseudorasbora parva Caught at River Kumho

국문 초록 (Abstract)

琴湖江에서 採集되는 참붕어에서 肝吸蟲 被裏幼蟲의 寄生狀의 變化를 究明하기 위해 1983年 3月부터 同年 9月까지 投網과 사발모지로 참붕어를 잡아 肝吸蟲 被裏幼蟲의 寄生率과 그 寄生程度를 調査한 다음 李 및 金(1958), 金(1961), 李(1968), Choi(1976) 및 Hwang 및 Choi(1980)의 調査成積과 比較하였다.
肝吸蟲 被裏幼蟲의 寄生程度의 標識으로서 魚肉 1gram當 被裏幼蟲數는 1958年 63.3個, 1968年 34.3個, 1976年 51.4個, 1980年 41.8個로써 그 數가 起伏을 나타내면서 減少되었으며 이번 1983年 調査에서는 7.9個로 急速히 減少되었음을 나타내었다.

다국어 초록 (Multilingual Abstract)

In order to determine the recent changes in infestation pattern of Clonorchis sinenisi metacercariae in the southern topmouthed minnow, Pseudorasbora parva, the fish were collected in the river Kumho, throwing a castnet and using a glass bowl containing crushed oil-cake as bait from March to September, 1984.
The infestation rates and intensity of infestation for C. sinensis in P. parva were determined and compared with the results reported by Lee and Kim(1958), Kim(1961), Lee(1968), Choi(1976), and Hwang and Choi(1980) in the same river.
The intensity of infestation with C. sinensis in P. parva, expressed in the average numbers of cysts per gram of flesh, were decreased with undulation from 1958 to 1980. The average number was 63.3 in 1958, 34.3 in 1968, 51.4 in 1976, and 41.8 in 1980, then dropped abruptly to 7.9 in 1983.
