Tope sharks have been exploited for many years in most parts of its range where its flesh is consumed by humans, its fins are used in shark fin soup, large quantities of vitamin A can be extracted from the oil in the liver, and the skin is made into leather products (1) (4). Large scale commercial fisheries targeting tope continue in many regions, including Uruguay, Argentina, California, southern Australia, and South Africa. Its life-history and biology make this species particularly vulnerable to overexploitation and fisheries for Tope in both California and Australia have collapsed. Currently, the Australian population has recovered and the fishery remains well-managed (9). Tope is also a common and popular catch of sports anglers (4). Tope sharks may also be threatened by the degradation of inshore nursery areas, as these habitats are particularly vulnerable to human activities (1). The installation of high-voltage cables under the sea bed can induce magnetic and electrical fields across their migration lanes (1), potentially disrupting their migration, and feeding and reproductive biology (6).
