| Abstract: | This paper deals with the analysis of the influence of high stocking density of Neosalanx taihuensis on its growth and biomass and the relation between stocking density and its population dynamics. A tentative discussion is given on the main reason of its population declining, according to its recources variation after transplantation to Dianchi Lake. |

| Keywords: | Neosalanx taihuensis r-selection population high stocking density population dynamics |
