| Abstract: | In order to identify Hexagrammos otakii stocks in adjacent waters,a total of 183 Hexagrammos otakii individuals are investigated from 7 wild populations (Lianyungang,Qingdao,Weihai,Yantai,Qinhuangdao,Dalian,Dandong) and 1 reared population (Weihai) in the coastal waters of the Yellow and Bohai Seas of China,multivariate statistical analysis of otolith morphology in different groups using traditional morphometry and Fourier analysis.Canonical discriminant analysis results show that 8 variables of traditional measurement entered in the CDA,9 harmonics EFDs entered in CDA with Fourier analysis,and the total correct classification is 79.2%.Phylogenetic analysis shows that the Weihai cultured population cluster in the outermost layer,and has the greatest difference with the wild populations,consistent with the discriminant scatter plot results.The Qingdao and Dandong wild populations are self-contained,distance from other groups and can be regarded as independent ecological communities.It is speculated that environmental factors are the main reasons for the differences in otolith among different populations. |
