摘要：

为验证耳石形态指标在斑尾复鰕虎鱼群体鉴别中的有效性。本研究运用4种统计方法对黄、渤海斑尾腹鰕虎鱼4个群体矢耳石进行分析。结果显示：烟台群体与青岛群体、烟台群体与天津群体、丹东群体与天津群体的9个耳石形态指标均存在显著差异；平均判别正确率为86.5%；构建的3个主成分贡献率分别为50.927%、24.179%、12.321%，累积贡献率为87.427%；聚类分析显示青岛和天津群体聚为一组，烟台与丹东群体聚为一组。4种分析方法均显示不同群体间耳石的差异，证实了耳石形态指标可作为黄、渤海斑尾复鰕虎鱼群体判别的参考依据。研究结果可为渔业资源的研究提供基础资料。

Abstract:

To verify the effectiveness of sagittate shape indices in population discrimination, sagittate of Synechogbius ommaturus from Yantai, Qingdao, Tianjin and Dandong were analyzed by one-way analysis of variance (ANOVA), discriminant analysis, principal component analysis and cluster analysis methods. The one-way ANOVA showed that there was significant difference in 9 sagittate shape indices between the populations of Yantai and Qingdao, Yantai and Tianjin, Tianjin and Dandong. The results of discriminant analysis revealed that the average discriminant accuracy was 81.3%. In principal component analysis, three principal components were constructed, with their contributory ratio being 50.927%, 24.179%, 12.321%，respectively. The cumulative contribution ratio was 87.427%. Cluster analysis showed the populations from Qingdao and Tianjin was classified as a group, the populations from Yantai and Dandong were classified as a group. The results of 4 statistical methods showed the differences among 4 populations and confirmed that sagittate shape indices could be an effective tool for population discrimination of S. ommaturus. The results provided basic data for the study of fishery resources.
