“…Because the allele number is positively related to the sample size as well as to the mutation rates at the polymorphic loci, the number of alleles observed at all 12 loci in this study is related to the relatively small size of the samples examined (Liu et al, 2009). Similar genetic variability has been reported for some other marine fish species (An et al, 2011a;Wang et al, 2011), suggesting that these polymorphic microsatellite loci were sufficient to reveal the intraspecific diversity among Labeo rohita.…”

“…We found that genetic diversity was similar in S. inermis, but the number of alleles per locus was relatively higher than that reported by An et al (2011a). Because allele number is positively correlated with sample size (Liu et al, 2009), the number of alleles observed in this study was probably due to the relatively large sample size. Overall heterozygosity associated with the microsatellite loci did not show pronounced differences between the populations examined.…”

“…On the other hand, the effect of random genetic drift could be an important reason for the significant differentiation. The random genetic drift may be caused by an unequal sex ratio or by the differential reproductive contribution of the brooders in the hatchery (Liu et al, 2009). …”

ABSTRACT. The black rockfish, Sebastes inermis (Sebastidae), is an important commercial fishery resource in Korea. As a preliminary investigation into the effect of artificial reproduction in a hatchery facility, the genetic divergence between parent and offspring populations of black rockfish was accessed using 10 polymorphic nuclear microsatellite DNA loci and a mitochondrial (mt) control gene. All loci that were screened showed marked polymorphisms. mtDNA control region sequences were also highly variable. Of approximately 350 base pairs (bp) sequenced, 52 variable sites, comprising 56 base substitutions, were found among 233 individuals. Offspring populations showed less genetic variability than the parent population in terms of numbers of microsatellite alleles and mtDNA haplotypes, as well as mtDNA haplotype diversity. Statistical analysis of the fixation index (Φ ST and F ST ) and analysis of molecular variance using both DNA markers showed significant genetic differences between the parent and offspring populations. These results suggest that random genetic drift and/or inbreeding events, as well as artificial selection and founder effects, occurred when the offspring strain was reproduced in a hatchery facility despite thousands of males and females from different hatcheries being maintained for artificial reproduction. Therefore, it is necessary to improve current hatchery programs by monitoring genetic variation in both the broodstock and progeny and controlling inbreeding within stocks in commercial breeding facilities to maintain the production of high-quality black rockfish. This information will be useful for determining suitable guidelines for establishing and maintaining cultured stocks and the aquaculture industry of S. inermis.

“…Molecular markers can be used to effectively estimate genetic variation and population structure in different populations, thereby providing a basis for better management of whole populations and thence sustainable fisheries (Liu et al, 2009;Yue et al, 2009). The COI gene is well characterized and is frequently used for genetic studies in invertebrates and vertebrates (Ward et al, 2005;Spies et al, 2006).…”

Eleutheronema tetradactylum is an important commercial fish species exposed to intense exploitation both in Southeast Asian countries and Northern parts of Australia. Research on the population structure of E. tetradactylum in these coastal waters is substantial in order to ensure sustainable use and appropriate resource management. In this study, genetic variation, diversity and population structure of E. tetradactylum among four FAO fishing areas, along South Asian countries, were evaluated using cytochrome c oxidase subunit I (COI) gene. Totally 30 sequences of COI gene were collected from four FAO fishing areas. Among these 30 individuals, 18 distinct haplotypes were defined. High levels of haplotype diversity (hd = 0.952 ± 0.096) and nucleotide diversity (π = 0.01536 ± 0.00312) were observed in the population within the Bay of Bengal. No haplotype and nucleotide diversity were observed in South China Sea population. Hierarchical analysis of molecular variance (AMOVA) indicated that whereas 0.81% of the genetic variation occurred within the populations, 7.09% occurred among populations. Significant genealogical branches were recognized in North Australian populations (one clade), South China Sea populations (one clade), Arabian Sea and Bay of Bengal populations (one clade on the neighbor-joining tree). These results suggested that E. tetradactylum populations in FAO fishing areas 51, 57 and 61 have developed different genetic structures. Tests of neutral evolution and mismatch distribution suggest that a population growth of E. tetradactylum may take place in these fishing areas.
