“…Anguilla bicolor from the Indian Ocean (A. bicolor bicolor) and the Paci c Ocean (A. bicolor paci ca) were found to diverge from each other (Fig. 3), and the outcomes of our COI gene sequence analysis were similar to those of previous studies using microsatellites, mitochondrial control regions and cytochrome b sequences 29,30 . These previous ndings also showed that A. bicolor in the two oceans has diverged into two subspecies.…”

“…A. bicolor has been differentiated into two subspecies: A. bicolor bicolor in the Indian Ocean and A. bicolor paci ca in the western Paci c Ocean 1 . There was no substantial difference observed in A. bicolor bicolor populations between the western and eastern sides of the Indian Ocean by means of morphological and DNA analyses [28][29][30] . However, two mitochondrial sublineages of A. bicolor bicolor were instead found sympatrically in the Indian Ocean 29,30 .…”

In contrast to A. marmorata and A. bicolor, however, the population genetic structure of A. bengalensis has never been examined, although a study based on morphological observation (total number of vertebrae) found that A. bengalensis has two subspecies, A. bengalensis labiata and A. bengalensis bengalensis, in the western and eastern Indian Oceans, respectively 1,31 .…”

Freshwater eels, genus Anguilla, have a distinctive catadromous life history, which could be associated with certain oceanic current systems and offshore spawning sites. Thus, migration and dispersion patterns are believed to be important factors influencing the population structures of each species. Temperate eel species are well studied, while little research has been conducted on the tropical counterparts that comprise two-thirds of all eel species. The population structures of three tropical species, A. marmorata, A. bicolor bicolor and A. bengalensis bengalensis, which are distributed widely in the Indo-Pacific region, were explored by means of DNA sequence analysis of mitochondrial cytochrome c oxidase subunit I (COI). This study found that A. bicolor bicolor had two genetically distinct populations, and these different populations co-occur geographically in the Indo-Pacific region, while A. marmorata and A. bengalensis bengalensis showed a panmictic-population structure in this region. The populations of A. bicolor bicolor were also found to have lower genetic variability than the populations of A. marmorata and A. bengalensis bengalensis. This study is the first to explore the population genetic structure of A. bengalensis bengalensis. The present results also suggest plausible dispersion and migration of these tropical species into their continental habitats.

“…Due to the wide geographical distribution, offshore spawning migration, passive larval transportation and the absence of significant physical barriers in the Indo-Pacific Ocean, a weak or an absence of population structure was expected for A. bicolor (Minegishi et al 2012, Fahmi et al 2015, as observed in temperate species such as Anguilla anguilla Linnaeus, 1758 (Palm et al 2009) and Anguilla japonica Temminck & Schlegel, 1846(Han et al 2008. However, based on its allopatric distribution and slight differences in morphological characteristics, A. bicolor has been subdivided into A. bicolor bicolor (Indian Ocean) and A. bicolor pacifica (western Pacific Ocean) (Ege 1939, Watanabe et al 2014.…”

The tropical anguillid eel, Anguilla bicolor McCelland, 1844, includes two subspecies, Anguilla bicolor bicolor McCelland, 1844 and Anguilla bicolor pacifica Schmidt, 1928, and is distributed across the Indo-Pacific region. Although A. bicolor is widely distributed and recognized as an important fish resource in the Indo-Pacific region, few studies have been conducted on its genetic variation and population structure. DNA barcoding of A. bicolor specimens collected in the Indo-Pacific region was carried out in this study using mitochondrial cytochrome c oxidase subunit I. Anguilla bicolor was found to diverge genetically, which supported its classification into two different subspecies. In addition, our study showed that A. bicolor bicolor had two genetically distinct populations/groups, and these different populations co-occur geographically in Indonesia and Malaysia in the eastern Indian Ocean. Our findings suggest that the eel larvae might be transported from at least two geographically different spawning grounds in the Indian Ocean, and then recruited to and settled in the same habitats in Indonesian and Malaysian waters. The molecular evidence calls for further research on the life history, stock assessment and protection of the populations of A. bicolor bicolor in Indonesia and Malaysia.
