Tanichthys albonubes is a cyprinid fish of South China and North Vietnam. Although this species has been sold worldwide in the aquarium trade for more than a century, it is listed as a second‐class state‐protected animal in China and classified as ‘extinct in nature’ in the China Red Data Book. To investigate the population history of T. albonubes and evaluate the genetic conditions among the wild and hatchery populations, mitochondrial genes (mtDNA, 2032 bp from the d‐loop and cyt b), nuclear genes (nuDNA, 2241 bp from RAG1 and ENC1) and 13 microsatellite loci were used to assess the genetic structure throughout the range of this species. In total, 358 specimens were collected from three hatcheries and all known wild populations. This study found that the discordant population structure among these genetic markers was accounted for by differences in the effective population sizes. The results indicated that (1) the three hatchery stocks originated from a single source in China and that the hatchery stock in China maintained almost all the T. albonubes genetic diversity in the downstream reaches of the Pearl River; (2) the wild population near Baiyun Mountain originated from hatchery releases; (3) the population history reflects the complex geological history of South China; and (4) the habitat destruction and fragmentation that have resulted in small and isolated populations may have shaped the genetic structure of T. albonubes. The low‐level genetic diversity of T. albonubes supports the need for conservation interventions. The geographically distinct genotypes indicate a need for the development of management strategies directed towards the conservation of localized populations. The genetic status of all populations, including the hatchery stocks, should be evaluated and monitored continuously.

Opsariichthine (sensu Oceanologi Et Limnologia Sinica , 1982, 13, 293–298) is a cyprinid group consisting of five genera and endemic to East Asia. Previous studies suggested that there may be many possible cryptic species in this group, but this has not been confirmed. In this study, using mitochondrial cyt b sequences on 1,388 samples and 739 haplotypes, we showed very high species diversity within this group. The results showed that phylogenetic relationships of the opsariichthine group were as ([ Nipponocypris ‐ Parazacco ‐ Candidia ] + [ Zacco + Opsariichthys ]), and there were multiple deep lineages within several species, flagging putative cryptic species. When a 3% genetic distance was used as a threshold for species delimitation, 35 haplogroups were found, nine haplogroups in Candidia ‐ Parazacco ‐ Nipponocypris group, six haplogroups in the Zacco group, and 20 haplogroups in the Opsariichthys group. We consider all of them to be putative until determination of distinct species based on the tree topology, geographic distributions, or a combination of both. In addition, two kinds of species delimitation tools, ABGD and PTP, were applied to construct molecular operational taxonomic units (MOTUs). The ABGD method revealed nine MOTUs in Candidia ‐ Parazacco ‐ Nipponocypris group, two MOTUs in the Zacco group, and 17 MOTUs in the Opsariichthys group. And the PTP method revealed 10 MOTUs in Candidia ‐ Parazacco ‐ Nipponocypris group, 10 MOTUs in the Zacco group, and 29 MOTUs in the Opsariichthys group. Therefore, there should be more species in the opsariichthine group than presently described. Based on the molecular data and morphological characteristics, we proposed Opsariichthys macrolepis as a valid species and described its morphological diagnostic characters.

“…To address the above problems, the mitochondrial DNA (mtDNA) cytochrome c oxidase subunit I (COI) was used to investigate the genetic diversity and structure of the Neocaridina species in Taiwan. The sequences of mtDNA are usually analysed in studies of animal phylogeography [9,23,27]. Among all the mtDNA genes, COI gene is a widely accepted marker to resolve the taxonomic identity and evaluate the levels of genetic diversity and differentiation in the Decapoda species [28,29].…”

Background The freshwater species in Taiwan Island have been documented originated from mainland China and Japan Islands multiple times and by multiple colonization routes. Moreover, the sequences from mitochondrial DNA cytochrome c oxidase subunit I (COI) have been used as DNA barcoding to identity species. This study used the COI sequences to identify Neocaridina species in Taiwan and examine their geographical and temporal origins. Results In total, 479 specimens were collected form 35 localities, which almost covers all rivers in Taiwan. The ML tree displayed that all sequences were assorted into 13 taxa (clades), and all sequences in Taiwan were assorted into four clades. The Bayesian skyline plots revealed that these four Neocaridina species in Taiwan declined recently. Conclusions All results support that (1) there are four Neocaridina species in Taiwan and they correspond to N. davidi , N. saccam , N. ketagalan and an undescribed Neocaridina species ( N. sp .); (2) these four species colonized Taiwan Island by four colonization events; (3) N. sp . colonized Taiwan before the Taiwan Island developed its shape and then restricted in East Taiwan; (4) after the island reached its shape, N. ketagalan and N. saccam colonized Taiwan from Japan Islands and mainland China, respectively; (5) N. davidi colonized northern Taiwan lastly; and (6) the cyclic glacial and landform changes shaped the colonization events and population structures of Neocaridina species.
