摘　　要：为了解西北太平洋重要鱼种形态结构多样性,有效提升该海域鱼类物种识别效率,利用地标点数据和几何形态测量学方法分析了西北太平洋8目14科24属26种鱼类(n=485尾)的形态差异,评估不同鱼体部位形态参数对物种识别的分类效果。结果显示,不同目和物种的鱼体形态存在显著差异,多元回归分析检测到部分物种存在异速生长现象。分类方面,鱼体和躯干部形状可以较好地区分不同物种。研究表明,西北太平洋海域鱼类物种具有多样的体型结构,不同物种生活史的异质性及遗传因素可能是导致体型多样性的原因。本研究可以提升西北太平洋海域的鱼类分类效果,为西北太平洋鱼类物种的可持续开发和有效资源管理提供科学依据。未来研究可以增加更多的物种和数量以便探究更加普适性的形态差异和分类效果。Fish body morphology contains important ecological information and is a valuable feature for species identification and population classification.There are many kinds of fish in Northwest Pacific Ocean,making the study of fish biodiversity a significant challenge in the study of fish morphology.At present,the study of fish species identification by using fish body geometric morphometrics is relatively lacking,and the classification effect of different fish body parts morphology is necessary to be discussed.In order to understand the morphological structural diversity of important fish species in Northwest Pacific Ocean,and effectively improve the efficiency of fish species identification in this area.In this study,the morphologies variation of 485 tails of 26 species from 24 genera,14 families and 8 orders in Northwest Pacific Ocean were constructed based on landmarks data and geometric morphometrics,and the taxonomic effects of different body morphological parameters on species recognition were evaluated.The results showed that there were significant differences in fish body morphology among different orders and species.In addition,Multiple regression analysis(MRA)detected allometry in some species.In terms of classification,and the body and torso shape could be better distinguished from different species.Studies have shown that fish species in Northwest Pacific Ocean have a variety of body shape structures,and the heterogeneity of the life history of different species and genetic factors may be the reasons for the body diversity.This study can improve the fish taxonomy in Northwest Pacific Ocean and provide a scientific basis for the sustainable development and effective resource management of fish species in Northwest Pacific Ocean.Future studies can add more species and numbers in order to explore more universal morphological differences and taxonomic effects.
