The complete mitochondrial genome of Indonesian snakehead, Channa micropeltes (Channiformes, Channidae).

ABSTRACT: Here we have characterized the complete mitochondrial genome of Indonesian snakehead, Channa micropeltes, and described its organization in this paper. The complete mitochondrial genome, 16,567?bp, is composed of 32.54% A, 14.05% G, 25.82% T and 27.59% C. It includes 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a 921-bp D-loop control region. Phylogenetic analysis with five more fish species demonstrated that the Indonesian snakehead is most closely related to the Great snakehead (Channa marulius). Our mitochondrial genomic data will also be valuable for the study on the mitochondrial evolution of fishes.

Project description:Background:The introduction of northern snakehead (Channa argus; Anabantiformes: Channidae) and their subsequent expansion is one of many problematic biological invasions in the United States. This harmful aquatic invasive species has become established in various parts of the eastern United States, including the Potomac River basin, and has recently become established in the Mississippi River basin in Arkansas. Effective management of C. argus and prevention of its further spread depends upon knowledge of current population structure in the United States. Methods:Novel methods for invasive species using whole genomic scans provide unprecedented levels of data, which are able to investigate fine scale differences between and within populations of organisms. In this study, we utilize 2b-RAD genomic sequencing to recover 1,007 single-nucleotide polymorphism (SNP) loci from genomic DNA extracted from 165 C. argus individuals: 147 individuals sampled along the East Coast of the United States and 18 individuals sampled throughout Arkansas. Results:Analysis of those SNP loci help to resolve existing population structure and recover five genetically distinct populations of C. argus in the United States. Additionally, information from the SNP loci enable us to begin to calculate the long-term effective population size ranges of this harmful aquatic invasive species. We estimate long-term Ne to be 1,840,000-18,400,000 for the Upper Hudson River basin, 4,537,500-45,375,000 for the Lower Hudson River basin, 3,422,500-34,225,000 for the Potomac River basin, 2,715,000-7,150,000 for Philadelphia, and 2,580,000-25,800,000 for Arkansas populations. Discussion and Conclusions:This work provides evidence for the presence of more genetic populations than previously estimated and estimates population size, showing the invasive potential of C. argus in the United States. The valuable information gained from this study will allow effective management of the existing populations to avoid expansion and possibly enable future eradication efforts.
