Research on ecological relationship between cyclops and microcystis aeruginosa

The relationship between cyclops and microcystis aeruginosa had been studied. The static test was divided into 5 groups in concordance with different proportion of populations and studied with periods of 13 days. The way of counting includes micro-metering and numbering. The results show that when the cyclops density is 100/L and the microcystis aeruginosa density is 10⁸/mL, they inhibite each other strikingly. When the microcystis aeruginosa density is reduced to 10⁷/mL, their inhibitory action is also obvious. And then if the cyclops density is reduced to 50/L, the inhibitory action becomes undistinguishable. So there is a proportional relationship between the inhibition intensity and their density. This study provides a new idea and theoretical basis for water bloom and cyclops overpopulated.
