Atlantic Sturgeon is a large sturgeon that can reach 14 feet and live for 60 years. Males do not mature until they reach about 4 feet and females mature later at about 6 feet. Females do not spawn every year and the time between spawns may be anywhere between 2 and 5 years (Smith 1985). The Shortnose Sturgeon Acipenser brevirostrum is a smaller fish that has been listed as endangered since 1967. For many years fisheries managers held out false hope that the actions in place to protect Shortnose Sturgeon would also protect Atlantic Sturgeon.
