TL;DR: From March 1973 to September 1974, fresh-water fishes were collected in rivers in Kyungpook Province, Korea, using three collecting technics; throwing a cast-net, fishing and using a glass bowl containing crushed oil-cake as a bait to examine the presence of the metacercaria of Clonorchis sinensis.
Abstract: From March 1973 to September 1974, fresh-water fishes were collected in rivers in Kyungpook Province, Korea, using three collecting technics; throwing a cast-net, fishing and using a glass bowl containing crushed oil-cake as a bait. Twenty-one species of the fish caught in the rivers in Kyungpook Province were examined for the presence of the metacercaria of Clonorchis sinensis. Of these, 10 speciec of the fish harbored the encysted larvae. The most frequently infected one was Pseudorasbora parva 92.3 per cent, followed by Pseudogobio esocinus 90.4 per cent, Sarcocheilichthys sinensis 87.7, Hemibarbus labeo 87.2, and Pungtungia herzi 60.8 per cent, in decreasing order. The less frequently infected were Erythroculter erythropterus 13.0, Acanthorhodeus taenianalis 7.7, Paracheilognathus rhombea 5.9 and Acheilognathus limbata 4.2 per cent. In the intensity of infection with the larvae, Pseudorasbora parva was most heavily infected and the mean number of metacercaria per ml of flesh was 51.4, Pungtungia herzi, Gnathopogon atromaculatus, Pseudogobio esocinus, Sarcocheilichthys sinensis and Homibarbus labeo were infected intermediately (Their mean number varied 10.3 to 19.5). Whereas, Paracheilognathus rhombea, Acheilognathus limbata and Acanthorbodeus taenianalis were infected with a few cysts.

TL;DR: It is found that clonorchiasis is less prevalent in Kyungpook Province than it was a decade ago and it continued to decline.
Abstract: This study was undertaken to evaluate the effects of health education and anti-Clonorchis campaign conducted in Kyungpook Province and to compare the prevalence of Clonorchis sinensis among the residents in the same areas for the period 1964-1976. Both surveys were made on all age groups of residents ranging from 0 to over 60 years of age. They were examined using primarily intradermal tests with Clonorchis and Paragonimus antigens and followed by stool examinations. The definitive diagnosis of clonorchiasis was made on the recovery of Clonorchis eggs from the stools. A marked reduction in the prevalence was encountered in the youngest age group, but there is no significant difference in the older age groups. The overall prevalence rate for clonorchiasis was reduced from 27.7 to 19.6 per cent in a period of 10 years. It is found that clonorchiasis is less prevalent in Kyungpook Province than it was a decade ago and it continued to decline.

TL;DR: Three different methods of coiling the long stylets within the head capsule in the Aradidae are described and the bearing of this on the relationships of the subfamilies is discussed.
