The genus Sebastes is an important component of the shelf and slope fish faunas of temperate and subarctic regions of the Northern Hemisphere. Although ecologically and economically important in Japanese waters, the early life history features of most Sebastes spp. are poorly known. From a historical point of view, this deficiency of knowledge has come from the deficiency of large-scale organized studies on wild resources of rockfishes by fisheries research institutions in Japan. On the other hand, many researchers investigated individually the reproductive features of fish including of coastal rockfishes before the mid-1970's. The technologies for mariculture of rockfishes, which have been developed since the mid-1970's are based on the knowledge of the reproductive features. In this paper, I detail new information on the early life history of rockfishes, which has up until now been deficient.
