“…Understanding the genetic background of a species is important, not only because of its fundamental relationship to biotic evolution (Jamaluddin et al 2019), but also to establish effective long-term management and conservation policies of biodiversity (Frankham 2009). Genetic variation and population structure (important embodiments of genetic diversity) are vital factors in the survival and adaptability of a species in response to changing environmental conditions (Frankham et al 2002;Bernatchez 2016).…”

“…To date, there is a lack of congruence of population genetic structure pattern among Southeast Asian freshwater fishes with respect to historical boundaries, geographical distances and morphological variations, which has revealed the influence of both intrinsic (e.g., dispersal ability, specific life-history characteristics, ecological interaction, adaptation to environmental perturbance, habitat preference and species age) and extrinsic (e.g., biotic interaction such as predation and competition and influence of tectonic and climatic changes) factors (Jamaluddin et al 2019). For instance, across the Mekong River, a comparative study delineated Channa striata into three divergent lineages while no population structure was observed in its congener, Channa micropeltes, attributed to the different demographic histories and responses to habitat changes (Adamson 2010).…”

“…Due to its relative abundance in mainland Southeast Asia, it is normally marketed fresh or dried, fetching a price of around USD 8/kg (MRC 2015). In Vietnam, the species is now being farmed on a small scale to support local demand (Jamaluddin et al 2019).…”

“…A previous study using mitochondrial DNA (mtDNA) reported the presence of two deep genetic lineages of M. favus as a result of dispersal and vicariance events, a consequence of river incision and capture related to geological events during the early Pliocene (Jamaluddin et al 2019). However, mtDNA sequence variation alone might not be sufficient to provide a complete evolutionary history of M. favus due to biasness associated with sex differences in dispersal rates, adaptive introgression and evolutionary rate variation (Toews and Brelsford 2012).…”

The tire track eel, Mastacembelus favus, is an economically important freshwater fish in mainland Southeast Asia. Understanding the spatial population structure is important to design an effective and efficient management of the species. The aim of this study was to investigate the genetic diversity and structure of M. favus populations. In total, 519 individuals from 30 locations across its distribution range were genotyped using a set of eight polymorphic microsatellite loci. Results showed that populations in Mekong and Chao Phraya exhibited higher genetic variability than those from Gulf of Thailand and Malay-Thai Peninsula. Clustering results revealed two evolutionarily isolated groups geographically separated at Northeastern Cambodia; the more widespread group was further divided into two subclusters. The spatial genetic variation and structure of its populations are attributed to the evolutionary history and population dynamics of the species. The study provides important information for the management and conservation of M. favus in Southeast Asia.

“…The complex geological history of the Oriental region caused a high degree of geographical genetic structure within freshwater organisms and species, once considered widely distributed in this region, are often formed by distinct genetic lineages (e.g. de Bruyn et al 2013;Dahruddin et al 2017;Jamaluddin et al 2019;Rüber et al 2020). The bronze featherback fish Notopterus notopterus, currently the only valid species of the genus Notopterus, is one of such widely-distributed species, occurring from the Indus basin (Pakistan and India) in the west, to the Mekong region -slightly extending east to the Annamite Range -(Cambodia, Laos, Thailand and Vietnam) in the east and to Java (Indonesia) in the south.…”

The fish genus Notopterus Lacepède, 1800 (Notopteridae) currently includes only one species, the Asian bronze featherback Notopterus notopterus (Pallas, 1769). This common freshwater species is widely distributed in the Oriental region, from the Indus basin in the west, the Mekong basin in the east and Java Island in the south. To examine the phylogeographic structure of N. notopterus across its range, we analysed 74 publicly available cytochrome oxidase I (COI) sequences, 72 of them determined from known-origin specimens, along with four newly-determined sequences from Peninsular Malaysian specimens. We found that N. notopterus is a complex of two allopatric species that diverge from each other by 7.5% mean p-distance. The first species is endemic to South Asia (from Indus basin to Ganga-Brahmaputra system), whereas the distribution of the second species is restricted to Southeast Asia. The exact limit between the distributions of these two species is not known, but it should fall somewhere between the Ganga-Brahmaputra and Salween basins, a region already identified as a major faunal boundary in the Oriental region. The name N. notopterus is retained for the Southeast Asian species, while the name Notopterus synurus (Bloch & Schneider, 1801) should be applied to the South Asian species. A comparative morphological study is needed to reveal the degree of morphological differentiation between the two species.

Population genetic structure of migratory fishes can reflect ecological and evolutionary processes. Pangasius krempfi is a critically important anadromous catfish in the Mekong River, and its migration pathways and genetic structure have attracted much interest. To investigate, we quantified the genetic diversity of this species using the control region (D‐loop) and Cytochrome b (Cyt b ) of the mitochondrial genome. Fish were sampled ( n = 91) along the Mekong tributaries from upstream to estuaries and coastal areas in the Mekong Delta and compared to three samples from Pakse (Laos). The D‐loop haplotype (0.941 ± 0.014) and nucleotide diversity (0.0083 ± 0.0005) were high in all populations, but that of Cyt b was low (0.331 ± 0.059 and 0.00063 ± 0.00011, respectively). No genetic difference was detected between populations, indicating strong gene flow and confirming a long migration distance for this species. Pangasius krempfi was not genetically structured according to geographical populations but was delineated into three haplogroups, suggesting multiple genetic lineages. The presence of haplogroups in each sampling location implies that migration downstream is random but parallel when the fish enter two river tributaries bifurcating from the main Mekong River. Individuals can also migrate along the coast, far from the estuaries, suggesting a longer migration path than previously reported, which is crucial for maintaining diverse genetic origin and migration pathways for P. krempfi .
