Abstract
The complete mitochondrial genome of Alosa sapidissima has been determined. The total length of the mitogenome was 16,697 bp and had a gene content (13 protein-coding, 22 tRNAs and 2 rRNAs. Except for the seven tRNA and Nd6 genes, all other mitochondrial genes are encoded on the heavy strand. The overall base composition of the heavy strand is 28.3% A, 24.8% T, 28.9% C, 17.9% G, with an AT content of 53.1%. The DNA sequence of Alosa. sapidissima shared 97.1, 93.9, 88.8 and 82.3% sequence identity with that of Alosa alosa, Alosa pseudoharengus. Molecular data here presented provide a useful toll for evolutionary as well as population genetic studied.
