“…Low nucleotide diversity was also established in mtDNA sequence analysis studies carried out in different countries for certain freshwater species with economic importance and having habitats disturbed by human activities, their results were in parallel to our study (Saraswat et al, 2014;Khaefi, Esmaeili, Ansari, & Ebrahimi, 2018;Behera et al, 2018;Zhao et al, 2018). Observed low values of nucleotide diversity (π) may be an indicator of occurrence adverse effects affecting on populations fitness and survivability, such as: bottleneck effect, inbreeding, outbreeding and hybridization, which are mainly related with antrophogenetic activities (Ma, Cheng, Zhang, Zhuang, & Zhao, 2010;Fennando, Pfrender, Encalada, & Lande, 2000).…”

It is substantially important to know genetic structure of fish populations for long term fishery and with regards to conservation strategies. The present study was aimed to reveal the fundamental population genetic data for continuity and conservation of the Yellow barbell (Carasobarbus luteus) stocks, being considered as an economically important endemic fish species in Southeastern Anatolia Region. Therefore, a total number of 108 fish specimens were sampled from 9 localities of Kueik, Euphrates and Tigris river systems and subsequently, genetically analyzed based on mtDNA D-loop region sequencing. In total, 15 polymorphic nucloetide sites and 7 haplotypes were established during the analysis carried out. The mean haplotype (Hd) and nucleotide variation (π) were calculated as 0.373 and 0.00536. The highest values of haplotype and nucleotide variation was observed in Birecik (Hd=0,65152) and Adıyaman population (π =0,01094); respectively. In turns, none haplotype and nucleotide variation was observed in Kilis and Diyarbakır populations. Obtained FST values for examined populations ranged between-0.12389 and 0.15630. All FST values were found to be statistically insignificant for the populations within the same river and significant between some populations originated from different rivers. According to analysis of neutrality tests, Tajima's D values were statistically significant in 4 populations (Samsat, Bozova, Hilvan and Bismil). Obtained, under the present study information on genetic variation and population structure of C. luteus will be useful to plan an effective strategies for conservation and fishery supplementation of the species in the region.

“…Low gene flow ( Nm < 1) could cause more genetic differentiation between populations, which might aid in the speciation process (Resende, Kavalco, & Pazza, ; Slatkin, ). The low gene flow level of the species may result in specific adaptations to local conditions and promotion of speciation events (Khaefi, Esmaeili, Ansari, & Ebrahimi, ). Obviously, significantly high Fst values (0.59536–0.94398) and low gene flow levels (0.01484–0.16991) among E. mongolicus , E. dabryi and E. ilishaeformis were found in this study (Table ), which indicated that significant genetic differentiations existed in the analysed three species.…”

Germplasm differences among three species of genus Erythroculter based on morphological characters and gene sequences of mitochondrial CO I and Cyt b

et al. 2019

Fish of genus Erythroculter (Cypriniformes, Cyprinidae, Abramidinae) are important commercial freshwater species in China. In this work, morphological characters and gene sequences of mitochondrial CO I and Cyt b were analysed to investigate the germplasm differences among E. mongolicus, E. dabryi and E. ilishaeformis. Results demonstrated that about countable trait, there were six traits (scale in/ above/ below lateral line, gill‐raker in first left gill‐arch and branched fin‐ray in anal/ pectoral fin) showed significant differences. Gene fragments of CO I and Cyt b was 905 bps and 1,142 bps respectively. In CO I, there were 54.3% base content of A + T, 14 haplotypes and 84 nucleotide variable sites. As to Cyt b, there were 56.3% base content of A + T, 20 haplotypes and 142 nucleotide variable sites. In both CO I and Cyt b, the highest and lowest nucleotide diversity was detected in E. ilishaeformis and E. mongolicus respectively. According to morphological distance, genetic distance, genetic differentiation coefficient (Fst) and gene flow, E. dabryi was grouped together with E. ilishaeformis firstly, and then clustered with E. mongolicus. These results might be useful in the conservation and management of fishery resources of these three species.

“…There is no sexual dimorphism in this species and both sexes have similar morphometric characteristics (Esmaeili et al 2018). The previous phylogenetic and phylogeographic studies found that populations of C. aculeata are different from the others (Zareian et al 2016;Khaefi et al 2018).…”

Abstract. Gandomkar H, Shekarabi SPH, Abdolhay HA, Nazari S, Mehrjan MS. 2020. Genetic structure of the Capoeta aculeata populations inferred from microsatellite DNA loci. Biodiversitas 21: 4565-4570. The present study aimed to investigate the genetic variation of Capoeta aculeata on the basis of DNA microsatellite loci from three rivers (Beshar, Khersan, Maroun) in Kohgiluyeh and Boyer-Ahmad Province in Iran. DNA from fin clips of 120 specimens extracted and was examined with eight microsatellite markers. Genetic differences between the populations were discerned by pairwise comparison based on allelic distribution. The average number of alleles per locus ranged from 4 to 14, while the average observed heterozygosity (Ho) at various loci varied between 0.212 to 0.579, implying that a moderate level of genetic variation. Among three populations, Maroun River population displayed the highest level of variability in terms of heterozygosity. Tests of Hardy-Weinberg showed that the microsatellite loci deviated significantly in the populations. The results indicate that some of the populations were significantly differentiated from one another based on pairwise FST estimates. Genetic distance-based measures supported the clustering of Maroun, Beshar, and Khersan rivers. The neighbor-joining dendrogram topology constructed on the basis of genetic distances among populations supported observed division between the populations. The non-significant differentiation between C. aculeata samples from Beshar and Khersan can be explained by a relative disconnection of these two populations and/or small amounts of gene flow.
