| 摘 要： | 目的]研究脊尾白虾（Exopalaemon carinicauda）和东方白虾（Exopalaemon ovientis）的体尺性状和形态特征。方法]采用形态度量和统计学t测验方法。结果]就抱卵期个体大小而言,脊尾白虾明显大于东方白虾;在形态特征上,2种白虾的差异也较大。t测验显示,脊尾白虾和东方白虾在头胸甲宽/体长、腹部宽/体长、头胸甲宽/头胸甲长等指标上有极显著差异,其中在指节长/腕节长上,2种虾的平均值分别为0.5365和0.8687,在所有的形态指标中差异最显著（t值为9.12）。结论]对脊尾白虾的健康养殖,应改变过去通过自然海区纳潮获得亲虾的方式,在养殖的各个阶段也应做好东方白虾发生情况的监控。

| Abstract: | Objective]The research aimed to study body-size traits and morphological characteristic of Exopalaemon carinicauda and Exopalaemon orientis.Method]The method of morphological measure and statistical t-test were used.Result]The results showed that on the body-size of egg-carrying shrimp,the individual value of E.carinicauda was bigger than that of Exopalaemon orientis.For the morphological characteristic,t-test showed there was significant variances between Exopalaemon carinicauda and Exopalaemon orientis... |
