摘要：

通过研究影响南极磷虾虾肉质量的主要形态特性,丰富南极磷虾生物学资料,同时为南极磷虾脱壳设备的设计提供理论基础。随机选取南极磷虾100尾,测定体长(X1)、头胸甲长(X2)、腹部长(X3)、尾扇长(X4)、头胸甲宽(X5)、腹部宽(X6)及虾肉质量(Y)7个形态特征,采用相关分析和通径分析方法分析形态特征对虾肉质量的影响效应。相关分析结果表明南极磷虾的形态特征与虾肉质量的相关系数均达到极显著水平(P<0.01);经通径分析和回归显著性检验,建立腹部长(X3)、腹部宽(X6)对虾肉质量(Y)的多元回归方程Y=-0.187+0.008X3+0.032X6,回归系数达到极显著水平(P<0.01)。通径分析显示,腹部长与腹部宽对虾肉质量的通径系数达到（极）显著水平,是影响虾肉质量的重要形态特征指标,其中腹部长对虾肉质量的直接作用最大;头胸甲长和头胸甲宽通过间接作用影响虾肉质量。

Abstract:

In order to provide biological data and a theoretical basis for the design of Antarctic Krill Sheller, the main morphometric attributes affecting the meat weight of Antarctic Krill were studied. A total of 100 Antarctic Krill were collected and the attributes including body length(X1), carapace length (X2), abdomen length(X3), tail fan length(X4), carapace width(X5), abdomen width(X6) and meat weight(Y) were measured. Methods of correlation analysis and path analysis were used to analyze the effects of morphological characteristics on meat weight of Antarctic Krill. The correlation analysis showed that, all correlation coefficients between morphometric attributes and meat weight achieved very significant difference (P<0.01). By path analysis and regression significance test, the abdomen length(X3) and abdomen width(X6) were used to establish the multiple regression equation, which was: Y=-0.187+0.008X3+0.032X6, and the regression coefficient of the above equation reached significant level (P<0.01). The path coefficients of abdomen length and abdomen width to the meat weight all achieved significant level (P<0.01). These attributes were very indicative of determining the meat weight, among them the abdomen length had the largest direct effect. The carapace length and carapace width affected meat weight indirectly.
