[目的]研究密度及雌雄比例对隆线溞混交雌体生殖方式的影响.
Abstract
[Objective] To study the effects of density and female-male ratio on the reproduction ways of D.carinata mictic female.[Method] Female D.carinata oviposited once of dormant eggs were divided according to different density and female-male ratio.The effects of density and female-male ratio on the reproduction ways of D.carinata mictic female were studied.[Result] When the density was 0.1, 0.2, 0.5, 0.8 and 1.0 ind./mL, there was no significant difference of dormant egg rate(P > 0.05).When the density of D.carinata was 2.0 ind./mL, its dormant egg rate was significantly higher than that of other five groups (P < 0.05), and its aestival egg rate was significantly lower than that of other five groups (P < 0.05).Different female-male ratio had no significant effects on the amount of dormant eggs of D.carinata mictic female (P>0.05).[Conclusion] The research results can provide foundation for the development and utilization of Cladocera as baits of aquatic animals.
