“…The individuals in SMR, SRC and HRK were only found to belong to lineage B, and the specimens from MTR, TLC, MRC and JRC were included in lineage A or B, respectively, while the specimens in CLR, BLJ and KLJ were only discovered in lineage A. This may partly result from different dispersal routes and different times of origination for the two lineages, and their arrival time was apparently less than one million years ago [11, 12, 43]. Demographic expansions were observed in each lineage, starting in the second-to-latest interglacial period for lineage A (209,533 yrs ago) and within the last glacial period in lineage B (49,248 yrs ago).…”

The oriental river prawn (Macrobrachium nipponense) is mainly distributed in East Asia. The phylogeography, population genetic structure and historical demography of this species in the East Asia were examined by using partial sequences of the cytochrome oxidase subunit I (COI) and 16S rRNA in mitochondrial DNA. Ten populations that included 239 individuals were collected from Taiwan (Shihmen Reservoir, SMR, Mingte Reservoir, MTR and Chengching Lake Reservoir, CLR), mainland China (Taihu Lake, TLC, Min River, MRC, Jiulong River, JRC and Shenzhen Reservoir, SRC), Japan (Biwa Lake, BLJ and Kasumigaura Lake, KLJ) and Korea (Han River, HRK). The nucleotide diversity (π) of all individuals was 0.01134, with values ranging from 0.0089 (BLJ, Japan) to 0.01425 (MTR, Taiwan). A total of 83 haplotypes were obtained, and the haplotypes were divided into 2 main lineages: lineage A included the specimens from BLJ, KLJ, CLR, MTR, TLC, MRC and JRC, and lineage B comprised the ones from HRK, SRC, SMR, MTR, TLC, MRC and JRC. Lineage A could be further divided two sub-lineages (A1 and A2). Individuals of lineage A2 were only from TLC. Demographic expansion was observed in each lineage, starting within the second-to-latest interglacial period for lineage A and within the last glacial period for lineage B. All FST values among the ten populations were significantly different, except for the values between MRC and JRC, and SMR and SRC. The phylogeography and genetic structure of M. nipponense in East Asia might be influenced by Pleistocene glacial cycles, lake isolation and human introduction. The possible dispersal routes of M. nipponense in the East Asia were also discussed.

“…) and mitten crabs (Xu et al . ; Xu & Chu ) showed that the East China Sea, South China Sea and the Sea of Japan were putative glacial refugia during the Pleistocene, contributing to the genetic diversification of these species. These phylogeographic studies have increased our understanding of the roles of Pleistocene glaciations and glacial refugia in shaping the population structure of marine inhabitants.…”

“…For example, by analyzing the population structures of seaweed, Ishige okamurae, Lee et al (2011) proposed Southern Korea, Northern Taiwan and Central Pacific Japan as possible refugia. Phylogeographic studies on the redlip mullet (Liu et al 2007) and mitten crabs (Xu et al 2009;Xu & Chu 2012) showed that the East China Sea, South China Sea and the Sea of Japan were putative glacial refugia during the Pleistocene, contributing to the genetic diversification of these species. These phylogeographic studies have increased our understanding of the roles of Pleistocene glaciations and glacial refugia in shaping the population structure of marine inhabitants.…”

Pleistocene glaciations were among the important historic events that shaped the population structures of marine organisms. Genetic studies of different marine fauna and flora have demonstrated the effect of Pleistocene glaciations on taxa that reside in marginal seas. However, how marine island species responded to Pleistocene glaciations remains relatively unstudied, especially in Asia. Genetic analyses based on the island‐associated barnacle Chthamalus moro collected from 14 sites in Asia reveal that C. moro comprises three distinct lineages, with COI divergence ranging from 3.9 to 8.3%. Population genetic analyses on respective lineages reveal signs of demographic expansion within the Pleistocene epoch at different times. The Ogasawara lineage, which has a more oceanic distribution, expanded the earliest, followed by the population expansion of the Ryukyu and Southern lineages that inhabit islands closer to the continent. The data suggest that the inhabitants of outer islands may have been less affected by Pleistocene glaciations than those that reside closer to the continent, as the former were able to maintain a large, stable, effective population size throughout the late Pleistocene.

“…Studies based on mitochondrial markers also presented consistent results with microsatellite markers that no significant genetic variability (haplotype and nucleotide diversities) was identified between populations in the Yangtze and Yellow Rivers (Wang et al , ). Therefore, the mitten crab populations in northern China are considered E. sinensis populations (Wang et al ; Xu et al ; Xu and Chu ). The Nanliu River in the southern part of China is considered the distribution area of E. hepuensis ; most studies indicated that E. hepuensis in this location show significant genetic variation and lower genetic diversity than those mitten crab populations in northern China (Sui et al ; Cheng et al ).…”

Chinese mitten crab, Eriocheir sinensis, is an important freshwater cultured crab in China with an annual production of approximately 800,000 m.t. and a value of 5 billion US dollars in 2014. The germplasm admixture and degeneration of E. sinensis are the most critical factors that restrict its aquaculture industry. Thus, genetic improvement programs of E. sinensis were initiated in 2000. The Ministry of Agriculture of China approved five selected varieties of E. sinensis, which are currently cultured throughout China and cover nearly 10% of the total yield of E. sinensis. The aquaculture status, genetic improvement practices, and achievement in E. sinensis aquaculture in China during the past 15 yr are summarized in this review.
