The complete mitochondrial genome of the Arctic staghorn sculpin Gymnocanthus tricuspis (Scorpaeniformes: Cottidae)

The complete mitochondrial genome was determined for Arctic staghorn sculpin Gymnocanthus tricuspis (Reinhardt, 1830), which is considered an important part of Arctic food webs. The mitogenome sequence is 16,570 bp in length containing 2 ribosomal RNA genes, 22 tRNA genes, 13 protein-coding genes, and 2 non-coding regions consist of control region (CR) and light-strand replication origin (O-L). The overall base composition of the mitogenome was estimated to be A 23.2%, T 29.0%, C 28.8%, and G 19.0%. The complete mitochondrial genome data will provide useful genetic information for future genetic variation identification and genetic diversity evaluation of this important species in Arctic Ocean.
