A REVIEW OF THE WELFARE IMPLICATIONS OF MODERN WHALING ACTIVITIES<br />
to be around 30,000 animals, <strong>and</strong> Japanese scientists warned that the hunting levels were<br />
unsustainable (EIA 1999).<br />
As a result of pressure from the IWC <strong>and</strong> the international community, the annual hunt has now<br />
been reduced to about 17,000 animals. There is, however, continued concern about the sustainability<br />
of this hunt <strong>and</strong> inadequacies in the reporting of the numbers killed.<br />
Killing methods<br />
Using specialised boats equipped with a bow platform, hunters travel offshore, anticipating that the<br />
Dall’s porpoises will ‘bow ride’ the boats 1 . The hunter leans from the platform <strong>and</strong> throws harpoons<br />
attached to long detachable shafts at the bow-riding porpoises. The harpoons are also attached to<br />
buoys by lines to secure the harpooned porpoises while the hunt continues for other porpoises. When<br />
the boat returns to collect the harpooned porpoises, they are dragged to the side of the boat <strong>and</strong><br />
brought aboard the vessel. Some hunters apply a charge of electricity to the animals through the<br />
harpoon as it strikes them, or once they are aboard, if they have not been killed by the impact of the<br />
harpoon. Porpoises which have not been killed by either the harpoon or the electricity will have their<br />
necks cut with a knife, probably from the underside of the head, so that they bleed to death.<br />
With numbers of Dall’s porpoises severely depleted in the Sea of Japan, hunters are targeting<br />
porpoises accompanied by calves. As the calves tire more quickly <strong>and</strong> the females will not ab<strong>and</strong>on<br />
them, they are, therefore, easier to catch. Although the hunters do not take them, ab<strong>and</strong>oned calves<br />
will inevitably die (Perry 1999).<br />
Baird’s beaked whale hunt<br />
Baird’s beaked whales reach a length of 12.8 metres (42 ft). The Japanese government sets itself a<br />
quota for 62 of these rare whales to be taken in its coastal waters each year. The Scientific Committee<br />
<strong>and</strong> Working Group on <strong>Whale</strong> Killing Methods of the IWC have not formally considered the hunt<br />
but since the moratorium was passed in 1982, 1032 Baird’s beaked whales have been killed in Japan’s<br />
coastal waters (EIA 1999).<br />
These whales have been hunted for several decades with heavy exploitation by Soviet <strong>and</strong> Japanese<br />
hunters until 1970. In 1952 alone, 332 whales were taken. In the 1970s the catch averaged 44<br />
whales per year <strong>and</strong> on the imposition of the moratorium in 1986, Japan set itself a quota of 40<br />
Baird’s beaked whales per year. In 1989, the quota was increased to 62 whales, with the claim that<br />
this was an emergency increase to be reduced if a coastal quota of 50 minke whales was granted to<br />
Japan. This was refused <strong>and</strong> Japan reduced the Baird’s beaked whale quota to 54 animals. In 1999<br />
the quota was arbitrarily increased to 62 whales.<br />
Killing methods<br />
Baird’s beaked whales are hunted off the Pacific coast of Japan <strong>and</strong> in the Sea of Japan off the coast of<br />
Hakodate, Hokkaido, using 48-ton ‘small type’ whaling boats. In the Sea of Japan, the boats travel to<br />
the feeding grounds (EIA 2003) where the whales are harpooned with a 50mm harpoon (Braund<br />
1989). There are indications that non-exploding or cold harpoons may be being used to kill some of<br />
the whales (EIA 2003). The cold harpoon was banned in 1980 by the IWC on welfare grounds<br />
(ICRW schedule). There is no information available on the implement used if the impact of the first<br />
harpoon does not kill the whales immediately. Reports from people associated with the Sea of Japan
