Tuna are large pelagic fish whose populations are close to panmixia. In addition, they are threatened species, so it is important for the maintenance and monitoring of genetic diversity that genetic information at a genome level be obtained. This project contains genome sequence data primarily of the southern bluefin tuna, with additional sequence data for the northern bluefin, the albacore, the bigeye, the skipjack, and the yellowfin tuna species.
