Abstract
A comprehensive review of the spawning regions and season in the waters around Japan, the maturity cycle and the female batch fecundity of Japanese jack mackerel and Japanese sardine was made in this paper. The maturity rate and the fluctuation for young cohorts (especially 1 year old fish) of these species are one of the most important factors especially for the estimation of the spawning stock biomass.
