琉球列島における両側回遊型魚類の生活史を解析した結果、その生活史は大きく非分散型と分散型に区分され、後者には地球の温暖化に伴う冬期の水温上昇により、分布を北上させている種がいることが明らかとなった。また従来、仔魚の分散のみが確認されていた種の一部には、沖縄島で越冬し、成長・産卵しているものが確認された。さらに、これまで個体数の少ない希少種であったものの中には、出現頻度が増加しつつある種がいることが明らかとなった。An analysis of the life histories of amphidromous fishes in Ryukyu Islands revealed that their life history strategies were roughly divided into two types。 The first was an undispersed type and the second was a dispersed type。 Some of the dispersed type fishes were found moving north of their distribution area and were located near Okinawa Island during the winter。 This phenomenon was thought to be mainly caused by the increase in water temperature during winter as a result of global warming.

The life history of migratory fish in the Ryukyu Islands is divided into two types: non-dispersed fish and dispersed fish. The latter type is related to the warming of the earth and the rise of water temperature in winter. A part of the species is confirmed to have overwintered, grown, and spawned. The number of individuals is small, the number of species is small, the frequency of occurrence is increasing, the number of species is small, the number of species is small, and the number of species is small.
