This guide is based on data collected by examining more than 500 dorsal fins and 900 pectoral fins from over 40 shark species, including all of the dominant species or species groups in the international fin trade reported in Clarke et al. (2006). Conspicuous fin markings were also assessed for pattern and consistency within species using photographs published in the scientific literature and on the Internet. Fin sets originated in the United States, Belize, Chile, South Africa, Fiji and New Zealand and included a wide size range for each species. Fins and fin sets examined in this study were provided by fishermen, fin traders and scientists; no sharks were sacrificed for this Project.
