Abstract
A series of this work has been undertaken to clear the present states of coastal fisheries and the biological characteristics of their resources. In present paper the author dealt with the drift gill-net fishery for flying-fishes as a part of this series, using the results of the test net at the coast of Tomioka, Amakusa Islands, Kyushu in 1955 and the records of the commercial catches from 1925 to 1960 at Tomioka. The conclutions obtained from this study are as follows: The stock of flying-fishes has a tendency to decrease in abundance. The catch per a boat-day is large and stable, considering its fishing method. This gill-net is very selective in its fishing and is almost used for taking dense schools of Cypselurus opisthopus hiraii. Namely, the catch and the fishing season of this fishery are greatly influenced by the quantity and the time of the spawning migration of this species.
