Draft Genome Sequence of Vibrio chagasii 18LP, Isolated from Gilthead Seabream (Sparus aurata) Larvae Reared in Aquaculture.

We report the draft genome sequence of Vibrio chagasii strain 18LP, isolated from gilthead seabream larvae at a fish hatchery research station in Portugal. The genome presents numerous features underlying opportunistic behavior, including genes coding for toxin biosynthesis and tolerance, host cell invasion, and heavy metal resistance.
