The slow growth, late sexual maturity and low reproductive output of the sandbar shark are all biological factors that make this shark vulnerable to overfishing. In most areas of its range, the sandbar shark is an important component of shark fisheries. The flesh is consumed by humans, the thick skins are prized for leather, vitamin-rich oil is extracted from the liver, and the fins are sold to Asian markets for use in shark fin soup (2). Although comprehensive catch data of this species is lacking, it is known to be severely overfished in the western North Atlantic (1), indicating that populations could be similarly impacted in other parts of its range. The inshore habitats which are important nursery grounds for the sandbar shark may also be impacted by the activities of humans which alter and degrade the natural environment (12).
