“…For example, the highest values for most of the diversity indices (Na=4.83; Ne=2.96; He=0.51) were observed for a pond whose owner is used to get fries from all over the area, thus increasing the existing variability; on the other hand, the lowest observed heterozygosity (0.35) was obtained for a pond neglected for more than 20 years, where very few individuals were found during the sampling, which had been interpreted as a sign of a critical situation. In general, the values obtained for PO are comparable with those obtained for many wild populations, indicating that the farming in the Poirino area did not induce the reduction of variability often observed in other species, including carp (Cyprinus carpio), which has a longer history of domestication (Kohlmann et al, 2005). On the other hand, the PO tench is farmed under an extensive breeding system, with the almost complete absence of selection and artificial reproduction, so that it can be considered at an intermediate level between wild and cultured populations.…”

The Tinca Gobba Dorata del Pianalto di Poirino (Golden humped tench of Poirino highland, [PO] 0.29 to 0.40). The analysis of between-population differentiation indicated that PO significantly differed from the others (FST = 0.039 to 0.097, P<0.05), while BO and TR were the most similar, consistently with their geographic proximity. The Neighbour-Joining tree revealed a clear separation between Northern and Central populations, with a bootstrap support of 97%. The population differentiation was reflected by the results of the assignment test, with 64% to 92% of the individuals correctly assigned to the original population, and a probability ranging from 76% to 95%. No individuals belonging to other populations were erroneously assigned to PO. A more detailed analysis of the PO population showed a similar genetic variability within the 15 considered ponds and a low degree of differentiation between ponds, with the exception of one "historical" pond, which significantly differed from most of the others, thus deserving to be preserved. The results indicate that the PO, despite being farmed, has a high level of withinpopulation diversity and is greatly differentiated from the other populations considered. The possibility of applying the assignment test in the framework of the product traceability deserves further investigation.

“…Among the 14 species barcoded fishes, four were introduced fishes i.e., Clarias gariepinus, Oreochromis niloticus, Xiphophorus hellerii, and Cyprinus carpio (see Lowe et al 2000, Anonymous 2011, and the rest indigenous species, two being endemic i.e., Rasbora tawarensis and Poropuntius tawarensis. Genetic study on C. carpio from Turkey and Uzbekistan were reported by some researchers (Murakaeva et al 2003, Kohlmann et al 2005, Memiş and Kohlmann 2006, and X. hellerii was reported by Mejía et al (2012), however, the genetic characteristic of wild C. carpio, X. hellerii, C. gariepinus, and O. niloticus from Lake Laut Tawar, Indonesia have not previously been evaluated. This study was the first report on the genetic status of freshwater fishes in Aceh region Indonesia, except for Rasbora group in Lake Laut Tawar which was reported by Muchlisin et al (2012).…”

“…In the current case, the presence of unrecognized null alleles and natural selection acting on genetic markers are unlikely explanations for the observed heterozygote deficits, because candidates for selection and null alleles, which affect both samples, were excluded before further analysis. In hatchery populations, heterozygote deficiency is commonly caused by a limited number of founders, or founder effects (Lundrigan et al, 2005;Kohlmann et al, 2005). In wild populations, a possible explanation for the heterozygote deficits is some form of assortative mating.…”

ABSTRACT. The tongue sole, Cynoglossus semilaevis (Cynoglossidae), is one of the most economically important fishery resources in Korea. This study presents a preliminary investigation of the future viability of the complete aquaculture of tongue sole in Korea. Specifically, possible differences in genetic variability between wild populations of tongue sole from Korea and hatchery-produced populations of tongue sole from China were assessed using multiplex assays with 12 polymorphic nuclear microsatellite DNA loci. High levels of polymorphism were observed between the 2 populations. A total of 135 different alleles were found, varying from 5-15 alleles per locus, with some alleles being unique. These findings indicate a high level of genetic variability in both the wild and hatchery-produced populations. Although a considerable loss of rare alleles was observed in hatchery samples, there were no statistically significant reductions of heterozygosity or allelic diversity in the hatchery population compared to the wild population. Moreover, the inbreeding coefficient was very low (F IS = -0.010-0.052) for both populations. However, significant genetic heterogeneity was found between the 2 populations. These findings indicate that genetic drift has likely promoted differentiation between these 2 populations, and might have negative effects on the reproductive capacity of the stock, because genetic factors are important in the production of high quality seed for complete aquaculture. Therefore, aquaculture management should incorporate basic genetic principles into existing molecular monitoring protocols. The information compiled by this study is anticipated to provide a useful genetic basis for future complete culturing plans and management of C. semilaevis in fisheries.
