Notes on the long-term transport of the scalloped hammerhead shark (Sphyrna lewini)

The capture and transport of scalloped hammerhead sharks (Sphyrna lewini Griffith and Smith, 1834) historically has represented a difficult, expensive, and uncertain undertaking for the public aquarium community. In this study, techniques were developed to improve the successful long-term transport of S. lewini by mitigating some of the deleterious effects associated with hyperactivity and impaired swimming patterns. The relationship between the transport vessel size and shark sizes, numbers, and swimming behavior was considered when formulating the transport regime. By balancing these factors and adopting a comprehensive water treatment method, it was possible to extend the duration of a successful transport by up to 60 hr. Implications for the future transport of S. lewini and other free-swimming sharks are discussed. (C) 2002 Wiley-Liss, Inc.
