Abstract:
In this paper, the complete mitochondrial DNA (mtDNA) sequence of Coilia ectenes was determined. The complete mtDNA genome sequence of C. ectenes is 16,852 bp in length. It consists of 13 protein-coding genes, 22 transfer RNA genes, two rRNA genes and two non-coding regions. Overall base composition of mitogenome is estimated to be 31.15% for A, 27.18% for C, 15.58% for G and 26.10% for T, respectively, with a high A+T content (57.25%). The complete mitogenome of the C. ectenes can provide a basic data for the studies on population history, molecular systematics, phylogeography, stock evaluation and conservation genetics. It is also helpful to the reasonable utilization and development of rational management strategies for C. ectenes resource.
