“…To tackle this issue further, a large-scale tagging study covering the entire geographic range of P. chinensis that involves both Chinese and Korean scientists is desirable. Table 1 for abbreviations of the localities Biochem Genet (2007) 45: 579-588 585 The sudden population expansion model and the lack of genetic population structure in P. chinensis are very similar to those reported in P. aztecus and P. duorarum Bert 2003, 2004), but differ from the distinct population structure found in P. setiferus (McMillen-Jackson and Bert 2003) and P. vannamei (Valles-Jimenez et al 2006). The latter two species spend most of their life inshore, and thus are greatly affected by inshore hydrological conditions that could create local differentiation over time.…”

“…Yet the mitochondrial 16S rRNA and COI genes used in the previous studies on P. chinensis are often used in elucidating population structure of penaeid shrimps over a broad geographic range (Klinbunga et al 2001;Tsoi et al 2007), but are too conserved to reveal genetic structure in a small geographic scale (Tsoi et al 2007), as in the case of P. chinensis. In the present study, we attempted to explore further the possible genetic differentiation of P. chinensis populations in the Bohai Sea and Yellow Sea by increasing the number of sampling localities and sample size, and by using the highly variable mitochondrial control region as the genetic marker, which has a high resolving power at the population level in penaeid shrimps (Chu et al 2003;Bert 2003, 2004;Valles-Jimenez et al 2006;Tsoi et al 2005Tsoi et al , 2007. The mutation rate of CR was estimated to be about 19% per MY (McMillen-Jackson and Bert 2003), as compared to 0.9% per MY for the 16S rRNA gene (Sturmbauer et al 1996) and 1.4% per MY for the COI gene (Knowlton and Weigt 1998).…”

Genetic differentiation of the shrimp Penaeus chinensis in the Yellow Sea and Bohai Sea was investigated using the mitochondrial control region (CR). RFLP of a partial CR segment (613 bp) shows that 106 out of 122 (86.9%) individuals from six sampling localities along the coast of northern China and the west coast of the Korean Peninsula share the same haplotype, and the haplotype frequencies among localities are not significantly different. The findings are further confirmed by sequencing the complete CR. Divergence of the complete CR (992 bp) is less than 1.6% in 14 individuals from the six localities. F-statistics based on RFLP data and the TCS network of sequencing data suggest little genetic differentiation of P. chinensis in the Yellow Sea and Bohai Sea. Mismatch analysis suggests a rapid expansion of P. chinensis population to the Yellow Sea and the Bohai Sea, which probably occurred with the rapid rise in sea level after the last glacial maximum. Despite the lack of genetic heterogeneity, we propose that P. chinensis populations in this region should be treated as separate management units, as fishery management programs have to be applied on a local basis by different governments.

-The white shrimp (Fenneropenaeus indicus)is an ecologically and economically important penaeid species, widely distributed in the Indo-Pacific region. To obtain information on the genetic variation and population structure of F. indicus, sequencing analysis was conducted on a fragment of cytochrome oxidase subunit I (COI) of the mitochondrial DNA. Individuals (n = 217) from eight locations covering four main geographic regions along the coastal belt of Sri Lanka were analysed. The sequences, a 602-base pairs (bp) fragment in length, revealed high haplotype and nucleotide diversity that yielded 82 haplotypes. A mismatch analysis produced a unimodal distribution of pairwise differences between haplotypes, consistent with a historic rapid population expansion. Little or no genetic differentiation was observed between most samples, although genetic distances based on pairwise differences between haplotypes started to increase when geographic distances exceeded about 130 km. A population in Bundala (southeast) had lower diversity and was genetically differentiated from the others. This information could be important for the sustainable management and utilization of this resource.

Selective breeding of the Pacifi c white shrimp Litopenaeus vannamei during the last decade has produced new varieties exhibiting high growth rates and disease resistance. However, the identifi cation of new varieties of shrimps from their phenotypic characters is diffi cult. This study introduces a new approach for identifying varieties of shrimps using molecular markers of microsatellites and mitochondrial control region sequences. The method was employed to identify a new selected variety, Kehai No. 1 (KH-1), from three representative stocks (control group): Zhengda; Tongwei; and a stock collected from Fujian Province, which is now cultured in mainland China. By pooled genotyping of KH-1 and the control group, fi ve microsatellites showing differences between KH-1 and the control group were screened out. Individual genotyping data confi rmed the results from pooled genotyping. The genotyping data for the fi ve microsatellites were applied to the assignment analysis of the KH-1 group and the control group using the partial Bayesian assignment method in GENECLASS2. By sequencing the mitochondrial control regions of individuals from the KH-1 and control group, four haplotypes were observed in the KH-1 group, whereas 14 haplotypes were obtained in the control group. By combining the microsatellite assignment analysis with mitochondrial control region analysis, the average accuracy of identifi cation of individuals in the KH-1 group and control group reached 89%. The fi ve selected microsatellite loci and mitochondrial control region sequences were highly polymorphic and could be used to distinguish new selected varieties of L . vannamei from other populations cultured in China.
