| Abstract: | The composition of zooplankton was investigated in Dalijia Lake in May,July,September and December of 2004.The results indicated there were 59 species of zooplankton.The abundance of zo- oplankton was 16475ind./L,the biomass of zooplankton could reach 0.3923mg/L.As the seasons changed,the abundance apex of zooplankton was 44200.0inch/L appeared in spring;and the biomass variation wasn't obvious.The total potential productivity of this reservoir was 3666kg,and 18330 stur- geons were stocked in it at present. |
