Three steps to using this field guide:
Step 1: Distinguish the highly-valued fin types: first dorsal fins and pectoral fins from lower caudal lobes. If it is a dorsal fin, proceed to Step 2. If it is a pectoral fin, proceed to Step 3.
Step 2: Distinguish oceanic whitetip, porbeagle, hammerhead, and silky first dorsal fins from non-CITES listed species using the flowchart in the guide.
Step 3: Distinguish oceanic whitetip, porbeagle, hammerhead, silky and thresher shark pectoral fins from non-CITES listed species using the flowchart in the guide.
