Spawning Area of the Japanese Eel

Abstract

The millennium-old mystery of eel spawning that has fascinated naturalists since the time of Aristotle still remains largely unsolved. There are only 3 species, the European eel, Anguilla anguilla, the American eel, A. rostrata, and the Japanese eel, A. japonica, for which the general spawning areas have been successfully outlined so far, but the spawning areas of the other 12 species of the genus Anguilla worldwide are still not well understood. In addition, even in the Atlantic Ocean, which has a long history of eel research, no one has ever observed spawning adults or collected eggs at the estimated spawning area in the Sargasso Sea. With respect to this point, the problem of the breeding place of freshwater eels has yet to be solved. Thus, research interest in eel migration is still focused on the actual spawning location for anguillid eels.
