 | | The northern right whale dolphin is endemic to the North Pacific, ranging from approximately 30°N to 50°N in the eastern Pacific (Leatherwood and Walker, 1979) and 35°N to 51°N in the western Pacific (Sleptsov, 1961; Nishiwaki, 1967; Kasuya, 1971). |
 | | From 1 June to 30 September, 1990 and 1991, 800 of the driftnet operations monitored in the central North Pacific (37°N to 46°N and 170°E to 150°W) resulted in the catches of northern right whale dolphin, Pacific white-sided dolphin or Dall's porpoise. |
 | | The LSM estimates for northern right whale dolphin, Pacific white-sided dolphin and Dall's porpoise were based on the life history investigations of Ferrero and Walker (1993), Ferrero and Walker (1996) and Ferrero and Walker (1999), respectively. |
