In the eastern Pacific, there were an estimated 228,038 coastal spotted dolphins in 2000 (CV=34%; Gerrodette and Forcada 2002a). The north-eastern offshore spotted dolphin (the form most affected by the ETP tuna fishery) numbered about 737,000 in 2003 (CV=15%; Gerrodette et al. 2005), a reduction of 76% from original size in 1959 (Reilly et al. 2005). This population is not showing clear signs of recovery despite the dramatic decline in mortality in recent years (Gerrodette and Forcada 2005). The western/southern offshore stock (which is less affected by the fishery) numbered about 876,075 in 2000 (CV=31%; Gerrodette and Forcada 2002b). In Hawaiian waters, there are an estimated 8,978 (CV=48%) (Barlow 2006). About 438,000 inhabited Japanese waters in the early 1990s (Miyashita 1993). There are estimated to be 34,067 (CV=18%) in the northern Gulf of Mexico (Mullin 2006), and 4,439 (CV=49%) along the east coast of the United States (Waring et al. 2006). Dolar et al (2006) estimated about 14,930 (CV=41%) for the eastern Sulu Sea and 640 (CV=27%) for the Tañon Strait between the islands of Negros and Cebu.
