Abstract: The study shows that the reproduction period of Neosalanx oligodontis is from earlyMarch to late May.Its spawning periods are the last ten days of March and April.Theage of sexual maturity is one year, belonging to the multiple spawning type.The fishfeeds zooplanktons during its whole life.After one year, its average total length is 44.2mm, and average body weight is 0.252g.The parents die off soon after their last spawning, and their life period is only one year.
