In this chapter, we discuss in detail an example of a small toothed whale hunt, with the aim of illustrating the methods used and the welfare questions that can arise in these cetacean hunts. Annually in Japanese waters, small cetaceans are killed in drive hunts with quotas set by the government of Japan. The Taiji Fishing Cooperative in Japan has published the details of a new killing method utilized in these specific hunts that involves cutting (transecting) the spinal cord. Reports claim that this method reduces the time to death. The method involves the repeated insertion of a metal rod followed by the plugging of the wound to prevent blood loss into the water. This method does not appear to lead to an immediate death. The method employed causes damage to the vertebral blood vessels and the vascular rete from insertion of the rod and leads to significant haemorrhage, but this damage alone would not produce a rapid death in a large mammal of this type. The method induces paraplegia (paralysis of the body) and death through trauma and gradual blood loss. We discuss in this chapter how this killing method compares to the recognized requirement for ‘immediate insensibility’ adopted in killing procedures utilized or considered acceptable in slaughter of farmed animals.
