本文以对比行为实验方法研究了克氏原贷虾的交配行为。结果表明，克氏原贷虾交配过程可分为交配前期和交配期。在交配前期，雄虾表现出特有的交配前期行为；交配期包括钳央、翻转、横跨、交尾和分离五个阶段。雌虾被雄虾钳住后表现顺从行为；而在对照组中的雌虾被同性钳住后却不表现顺从行为，雄虾之间的接触导致进攻行为。交配时雄虾横跨的步足均为右第5步足；雌虾在交配前勿需生殖蜕皮，交配的成败与雄虾接近雌虾的行为方式有关，且螯足较大大的雄性个体交配成功率明显较高。
In this paper, the behavioral experiment was conducted to study the mating behavior of Procambarus clarkii. The results showed that the process of copulation can be divided into pre-mating and mating stages. In the early mating period, male shrimp showed unique pre-mating behavior; mating period including clamp central, flip, cross, cross and the separation of five stages. The female shrimp was compacted by the male shrimp, whereas the female shrimp in the control group did not behave in the same manner after being clamped by the same sex. The contact between male and female shrimp resulted in offensive behavior. Mating males walk across the steps are the right foot Step 5; females do not need to reproductive molting before mating, mate success or failure with male shrimp close to the behavior of females, The success rate is significantly higher.
