摘要

在ALPEL2018(地中海西南部，GFCM-GSA04)声学调查期间，对阿尔及利亚水域六个地点采集的欧洲凤尾鱼(Engraulis encrasicolus)样本进行了身体形态特征和耳石形状的椭圆傅里叶描述子分析。对12个形态体距离和31个归一化椭圆傅里叶描述子进行了判别分析。它突出了区域之间的显著差异，但高度重叠。在男性和女性之间，或者左右耳石之间，没有发现显著差异。对体型和耳石形状的平均形态进行了层次聚类分析，结果显示出明显的地理差异。结果表明，地理趋势是在附近区域之间存在高度重叠，这表明阿尔及利亚水域的欧洲凤尾鱼并非完全孤立。

Body morphometric and otolith shape analyses of anchovy (Engraulis encrasicolus (Linnaeus, 1758)) in the Algerian basin

Body morphometric characteristics and otolith shape described by elliptic Fourier descriptors analyses were carried out on European anchovy (Engraulis encrasicolus) samples collected from six locations in Algerian waters during the acoustic survey ALPEL2018 (south-western Mediterranean Sea, GFCM-GSA04). The discriminant analysis was applied over twelve morphometric body distances and 31 normalized elliptic Fourier descriptors. It highlighted significant difference between areas but with high overlapping. No significant difference was detected between males and females, or right and left otoliths. Hierarchical clustering analysis conducted on the mean form of body and otolith shape showed a clear geographical cline. The results indicate that the geographical trend is present with a high level of overlapping between the near areas, suggesting that European anchovies in Algerian waters are not completely isolated.
