| Abstract: | The Songnen Plain is aboundant in potamogeton crispus resources,the avreage biamass is over 1300kg/ha. The total area of waters with P. csispus is 298300ha, making up 57% of the total arca of fishery water in this region. In order to ex-ploit them rationally, fishery utilization and its value were researched in Xinhu-angpao, Yueliangpao and Xidadupao reservoir of Jiling Province, during 1984-1992. The results of the investigation and research on the P, crispus resources of fishery waters in Songnen Plain area and state of food resources (phytoplankton, bethitic organisms, epiphyte and aquatic vascular flora) in waters with P. crispus are reported in this paper. These factors are compared with the waters without vegetation under the same conditions. Fish production in waters with P. crispus is also estimated. Rational fishery utilization of P.'crispus resources is approached according to experimental results concerned, |
