Cetaceans of the Channel Islands National Marine Sanctuary / prepared for National Oceanic and Atmospheric Administration, Channel Islands National Marine Sanctuary and NOAA, National Marine Fisheries Service by Stephen Leatherwood, Brent S. Stewart, Pieter A. Folkens. Whales California Channel Islands.. MEDIUM-SIZED CETACEANS (to 13 meters maximum length) This section includes one baleen whale, the minke, and eight toothed whales. Of these latter, only three are seen in significant frequency in the SCB. The others are rarely seen or positively identified in the area. Residents and Common Migrants. Minke Whale Bakencptera acutorostrata Lacepede, 1804 Although the minke whale has a world-wide distribution, because of its small size it was not actively hunted by commercial whalers in most areas until the reduction in populations of larger, more valuable, species (such as right, bowhead, blue, fin and sei whales) required a shift in whaling focus. In the North Pacific, minke whales were killed, historically, in very small numbers by natives ol the Pacific Northwest of North America, especially those at Cape Flattery, Washington. Minke whales began to be exploited in the coastal waters of Japan several centuries ago. Whalers used the traditional multiple boat driving and killing methods employed for the larger species. The Norwegian method of whaling using small catcher boats, introduced to Japan in about 1890, was used to take minke whales, but they were not the primary species pursued and did not, until recently, become the object of a focused fishery in Japanese waters. Following the introduction of modern catcher boats in Japan in the 1920s, the coastal fishery there expanded. Russian pelagic whaling fleets began taking minke whales in 1933 off the east coast of Kamchatka, in the Bering Sea and in the Arctic Ocean. Japanese pelagic vessels began exploiting minke whales in the Northwest Pacific in 1930. The annual catch in this last fishery increased slightly throu
