Long-beaked common dolphin are known to be taken in bottom-set gillnets and purse seine fisheries off southern California, but potential impacts are uncertain. Some bycatch has also been documented in drift gillnets off California (Carretta et al. 2005). They are only occasionally involved as bycatch in the eastern tropical Pacific tuna fishery. They are present off Japan, and some have been taken in drive fisheries there. There are anecdotal reports of potentially large numbers of dolphins, including long-beaked common dolphins, killed for bait in some coastal fisheries off Baja California, Mexico (K. Forney pers. comm.). Long-beaked common dolphins have been taken opportunistically by harpoon in northeastern Taiwan and are caught incidentally by oceanic driftnets off eastern Taiwan (J. Wang pers. comm.). There is a large direct kill around Margarita Island, off eastern Venezuela, in which dolphins are harpooned in large numbers (Romero et al. 2001). In the Indian Ocean and Chinese waters, they are taken in gillnets, trawls, and purse seines. There is growing concern about the large numbers of long-beaked common dolphins killed off Peru and used for human food or shark bait (K. Van Waerebeek pers. comm.). Incidental catches of Delphinus sp. in pelagic driftnets in southern and south-eastern Brazil have been recorded (Zerbini and Kotas 1998), but no current estimates of bycatch are available. Given that this fishery occurs in the presumed range of the species, some of these individuals may belong to this species.
