Major Threats
Small numbers of Fraser's dolphins are taken regularly or opportunistically by harpoon in the Lesser Antilles, Sri Lanka, Indonesia (Kahn 2004), the Philippines, Taiwan and probably elsewhere in the Indo-Pacific (Jefferson and Leatherwood 1994). A few have been taken in drive fisheries in Taiwan and Japan (Perrin et al. 1994). Dolar et al. (1994) investigated directed fisheries for marine mammals in central and southern Visayas, northern Mindanao and Palawan, Philippines. Some of the hunters take only dolphins, for bait or human consumption and the species taken include Fraser's dolphins. Around 800 cetaceans are taken annually by hunters at the seven sites, mostly during the inter-monsoonal period of February-May.
Some Fraser’s dolphins are killed incidentally in the tuna purse-seine fishery in the eastern tropical Pacific (Gerrodette and Wade 1991): 26 were estimated taken during the period 1971 - 75. A few are also taken in gill nets in Sri Lanka, the Philippines, and likely in other tropical gillnet fisheries as well. Some are killed by anti-shark nets in South Africa (Perrin et al. 1994; Cockcroft 1990). Other incidental catches in purse seines (Philippines), gillnets, driftnets (Taiwan), and trap nets (Japan) are also known (Jefferson and Leatherwood 1994).
