The availability of the Japanese eight-barbel loach Lefua echigonia as a host fish for the glochidia of the unionid mussel Pronodularia japanensis was investigated. The hosts to which the glochidia were attached in a paddy field ditch were cultured in tanks (6 l, 28 +- 0.5 deg C) for nine days. Glochidia and juveniles that became detached from the hosts were counted daily. Juveniles appeared about six days after glochidia attachment. L. echigonia is thought to be a suitable host, on which over 10% of attached glochidia metamorphosed to juveniles.
