Abstract

The complete mitochondrial genome of Electrona carlsbergi was obtained, which was 18,282 bp in size and including 13 protein-coding genes, 2 ribosomal RNAs, 23 transfer RNAs and 1 control region. The overall nucleotide composition is 27.92% for A, 24.66% for T, 30.90% for C and 16.52% for G. Among 23 tRNA genes, 8 tRNAs were encoded on the L-strand. Further, the phylogenetic tree, which based on complete mtDNA sequences, revealed that the E. carlsbergi was genetically closest to species E. antarctica and Krefftichthys anderssoni. This study could provide a basic data for the studies on evolution for low temperature adaptability, stock evaluation and conservation genetics.
