“…The Leizhou Peninsula is the third-largest peninsula located at the southernmost tip of China. Combined with Hainan island, they form a natural geographic barrier between the Gulf of Tonkin and the rest of the South China Sea, with only a long and narrow Qingzhou strait flowing through (Sun and Tang, 2018). Such natural geographic isolation also represents a barrier to gene flow among populations, and substantial population differentiation was usually detected in marine species dwelling on both sides of the peninsula (Sun and Tang, 2018;Wang et al, 2019;Yi et al, 2021).…”

Amphioctopus aegina is an important fishery resource in the coastal waters of China. In the present study, the genetic diversity and population genetic structure among four populations of A. aegina throughout its distributional range in China were assessed using the mitochondrial cytochrome oxidase 1 (COI) sequences. The results revealed a generally low genetic diversity (Hd: 0.2842–0.6670; Pi: 0.0007–0.0015) in A. aegina populations. The neighbor-joining (NJ) phylogenetic tree and the haplotype networks, as well as the results of the molecular variance (AMOVA) analyses, indicated a shallow phylogeographic structure among the four populations. However, pairwise ΦST statistics and genetic distance analyses revealed significant (p<0.01) genetic differentiation among Qinzhou and the rest three populations of Zhanjiang, Huizhou, and Dongshan. The demographic history analyses indicated a population expansion in A. aegina, and the role of Leizhou peninsula isolation in shaping the population differentiation. These results would largely enhance our understanding of the genetic structure and hence promote the scientific management of A. aegina fishery resources in coastal waters of China.

“…Insight into genetic diversity and population genetic structure are essential for resource recovery and fishery management in fishes (Waples et al 2008 ). In recent years, the study on population genetic of fish has attracted considerable interest (Sun et al 2013 ; Kunal et al 2013 ; Sun and Tang 2018 ; Li et al 2019 ). The mtDNA control region has been proved to be useful for population studies of marine fishes (Liu et al 2009 ; Shui et al 2009 ; Sun et al 2013 ).…”

“…However, the population genetic background was still not clear in other Pampus species. Our previous study (Sun and Tang 2018 ) evaluated the P. chinensis along the China coast using mitochondrial DNA cytochrome b (cyt b) gene sequences. Results showed high level of haplotype diversity (0.540–0.828) and low level of nucleotide diversity (0.081–0.210%).…”

“…In recent decades, however, decline due to marine pollution and overfishing was found in this marine species (Zheng et al 2003 ; Siyal 2013 ). To date, genetic background of P. chinensis is very limited (Cui et al 2010 ; Sun et al 2012 ; Sun and Tang 2018 ; Li et al 2019 ), and limited information was known about its genetic structure and factors that influence it. Mitochondrial DNA (mtDNA) is proved to be an ideal marker for population genetic study, among which the control region gene has been reported to be highly sensitive in detecting population genetic structure and genetic diversity, and hence has been applied to population studies in various fish species, such as Schizothorax prenanti , Scomberomorus niphonius , Auxis thazard, Katsuwonus pelamis , P. argenteus , Thunnus albacares , etc.…”

Pampus chinensis is a commercially important fishery species in the Indo-West Pacific region. In the present study, the genetic variation of P. chinensis among 10 sampling localities along the China coast and one from the Indonesia region was evaluated using mitochondrial DNA control region sequences. As a result, a total of 30 variable sites were detected in the 458 bp segment of the control region among 330 individuals from 11 localities, and 41 haplotypes were defined. Samples in the China coast present a high level of genetic diversity, with the values of haplotype diversity ranged from 0.674 to 0.860, and nucleotide diversity from 0.820% to 1.502%. Pairwise F ST statistics showed a moderate genetic divergence (À0.027 to 0.384) among samples from different geographical locations. Median-joining network analysis revealed a similar pattern of phylogeographic structure in samples from Ningbo and Dongxing although they were far apart. Therefore, joint influences of dispersal capability, spatial distance, ocean current and geographic segregation on the formation of the present population structure in P. chinensis was proposed. The results of the present study would be helpful for the sustainable utilization and management of this species.

The southern lesser pomfret (Pampus minor) is an economically important fish, and its numbers are declining because of overfishing and environmental pollution. In addition, owing to the similarities of its external morphological characteristics to other species in the genus Pampus, it is often mistaken for grey pomfret (P. cinereus) or silver pomfret (P. argenteus) juveniles. In this study, the genetic diversity and structure of 264 P. minor individuals from 11 populations in China and Malaysia coastal waters were evaluated for the first time, to the best of our knowledge, using mitochondrial cytochrome b fragments. The results showed that P. minor had moderate haplotype diversity and low nucleotide diversity. Furthermore, two divergent lineages were detected within the populations, but the phylogenetic structure corresponded imperfectly with geographical location; thus, the populations may have diverged in different glacial refugia during the Pleistocene low sea levels. Analysis of molecular variation (AMOVA) showed that genetic variation originated primarily from individuals within the population. Pairwise FST results showed significant differentiation between the Chinese and Malaysian populations. Except for the Xiamen population, which was classified as a marginal population, the genetic differentiation among the other Chinese populations was not significant. During the Late Pleistocene, P. minor experienced a population expansion event starting from the South China Sea refugium that expanded outward, and derivative populations quickly occupied and adapted to the new habitat. The results of this study will provide genetic information for the scientific conservation and management of P. minor resources.
