Population genetic diversity of Chinese sea bass (Lateolabrax maculatus) from southeast coastal regions of China based on mitochondrial COI gene sequences
چکیده انگلیسی
Chinese sea bass (Lateolabrax maculatus), an important commercial and recreational fishery species in China, whose natural resources have decreased dramatically for decades due to overfishing and environmental changes. To provide guidelines for the source conservation and management, genetic diversity and population structure of L. maculatus were analyzed based on the mitochondrial cytochrome oxidase subunit I (COI) gene. Totally 192 individuals were sampled from five locations: Qingdao (QD), Chongming (CM), Dongtou (DT), Lieyu (LY) and Fangcheng (FC). After sequencing of a 586 bp fragment of COI gene, 20 haplotypes were defined. H4 (haplotype 4) and H8 were the dominant haplotypes and existed in all populations. Haplotype diversity (Hd) and nucleotide diversity (π) of each population ranged from 0.572 to 0.721 and from 0.00129 to 0.00271, respectively. The highest Hd and π were found in DT and LY populations, while the lowest value of Hd and π were in the QD population. Genetic distance ranged from 0.0031 to 0.0027 within populations and from 0.0018 to 0.0035 between populations. Analysis of molecular variance (AMOVA) revealed that significant genetic divergence was found in QD and FC populations. In addition, neutrality tests and mismatch distribution analysis indicated that this species experienced potential population expansion events.
