Abstract

|
|
|
Acanthocephalan worms were harvested from the posterior intestines of the cultured marine fishes from January to July 2016 in a fish market located in Daejeon metropolitan city, Republic of Korea. Totally 450 cultured fishes (rock fish 100, olive flounder 250, red sea bream 100) were surveyed. Of the 100 red sea bream fish, 37 fishes (37%) were diagnosed as positive for Longicollum pagrosomi by light, electron microscopic and molecular examination. The number of worm was 25∼78 (mean 51±13). However, we can`t found any worm from the cultured rock fish and olive flounder. After sequencing, none of Pomphorhynchidae family are not identical based on 18S rRNA gene, and this data were identified with the first report for 18S rRNA gene sequence of L. pagrosomi. Furthermore, we confirmed that L. pagrosomi of the cultured red sea bream in Republic of Korea is very common parasite.
