Degree of Threat: C : Not very threatened throughout its range, communities often provide natural resources that when exploited alter the composition and structure over the short-term, or communities are self-protecting because they are unsuitable for other uses
Comments: Some populations have declined as result of mortality associated with purse-seine tuna fishery in eastern tropical Pacific (Smith 1983, IUCN 1991); takes of 100,000s per year occurred in the 1960s and 1970s (Jefferson et al. 1993); estimated that 70,000 were killed in 1986 (IUCN 1991); annual mortality in the late 1980s was in the 10,000s (Jefferson et al. 1993). Taken also in drive fisheries in Japan and the Solomon Islands, in gillnet and harpoon fisheries in Sri Lanka, and in the Caribbean small cetacean fishery, among others (Jefferson et al. 1993).
