Abstract
The habitat of Aphyocypris chinensis in Jeollabuk-do, Korea was surveyed in March and July 2007 to obtain basic information on its habitat preference. The data obtained are expected to contribute to the conservation of the endangered Japanese population of the present species. Twenty species including A. chinensis, belonging to nine fish families, were caught at four stations using a wide hand net. Among these, Carassius spp., Macropodus ocellatus and Monopterus albus were found in habitats similar to that of A. chinensis. The habitats in Korea were similar to a nearly traditional irrigation canal, which are identical to those in Japan. From this survey, we confirm that a traditional style of farming provides the most suitable habitat for A. chinensis.
