Comments: This is the major marine mammal taken incidently in the extensive squid driftnet fishery that operates out of Japan, Korea, and Taiwan, which probably has greatly reduced the population in the western Pacific (take was estimated at 15,000-20,000 per year in the late 1980s); occasionally taken in salmon gillnet fisheries and in driftnets set for sharks and swordfish (Jefferson and Newcomer 1993).
