Documents the remarkable progress achieved in understanding the life cycle of eels, including the discovery of the spawning area of the Japanese eel and the migratory route of its larvae. With the development of techniques for artificial induction of gonadal maturation, it became possible to obtain hatched larvae. Larval rearing to the leptocephalus stage, one of the most difficult tasks involved in eel culture, was finally achieved.
