The welfare implications of each whaling technique will be considered in this chapter. Table 1 shows<br />
the number <strong>and</strong> species of whales killed over the last five years by Japan <strong>and</strong> Norway, the average <strong>and</strong><br />
maximum time they took to die (time to death, TTD), the instantaneous death rate (IDR) <strong>and</strong> the<br />
proportion of animals shot but lost (the ‘struck <strong>and</strong> lost’ rate, SLR).<br />
Killing methods used during commercial <strong>and</strong> special permit whaling<br />
With the exception of bycaught whales (discussed later in this chapter), the methods used by Japan,<br />
Icel<strong>and</strong> <strong>and</strong> Norway for killing whales are very similar. In each case, whalers use a penthrite grenade<br />
harpoon, which is fired from a cannon mounted on the prow of a ship, as the primary killing<br />
method. The harpoon is intended to penetrate to about a foot (approx 30cm) into the whale <strong>and</strong><br />
then detonate, creating sufficient energy to kill the whale either by the trauma or laceration, or by<br />
the generation of shock waves, causing trauma to the brain. Upon impact, spring-loaded claws are<br />
released by the harpoon <strong>and</strong> embed in the surrounding flesh when the line comes under tension. If<br />
the whalers determine that the first harpoon has not killed the whale, either a second penthrite<br />
harpoon is deployed or a rifle (of minimum calibre 9.3mm) is used as a ‘secondary killing method’ in<br />
both the Norwegian <strong>and</strong> Japanese hunts. Until recently, Japan used electricity as a secondary killing<br />
method.<br />
