摘要
测量并分析了４２７尾长湖青虾的全长、体长、头胸甲及额剑长、体重及其相互关系，结果表明这些形态参数间的相关性较好，可用方程式表示；还研究了腹宽／体长、甲宽／体长、全长／体长三者与体长的关系，得出体长３～４ｃｍ左右是长湖青虾体型趋于稳定的转折点。
The whole length, body length, cephalothorax and rostrum length and body weight of 427 Macrobrachium nipponensis were determined and analysed. The relations among these morphological parameters can be conveyed by equations and these coefficients of correlations are higher. The abdomn width and cephalothorax width have been studied, too. The reslt express that the body length of 3.0～4.0 cm is a turning point of study body form.
