More information is needed on the extent of the exploitation of Peale's dolphin for crab bait (4) (7). The Chilean government has undertaken some measures to help regulate the use of marine mammals in crab fisheries, including educating fishing communities and providing alternative sources of bait, and the practice of using dolphins as bait is reported to have declined in recent years. However, a certain amount of illegal fishing and baiting may continue (7). Other recommended conservation actions for Peale's dolphin include further research into its biology and abundance, identification and protection of key habitats, education campaigns, and enforcement of hunting regulations (1) (11). In addition to its listing on Appendix II of the Convention on International Trade in Endangered Species (CITES) (3), meaning international trade in Peale's dolphin should be carefully controlled, the species is also listed on Appendix II of the Convention on Migratory Species (CMS) (12), based on the fact that its movement through the Beagle Channel and Strait of Magellan is likely to involve the national boundaries of Argentina and Chile (11).
