As has been reported by myself and others, Iceland has resumed commercial whaling, killing an endangered fin whale earlier this week. However, Norway and Japan have been engaging in commercial whaling, either blatantly or under the auspices of “scientific research,” for quite some time. This is quite a sensitive issue in global politics, involving high emotions on either side. Pro-whalers argue that some commercial whale populations have rebounded and are viable for sustainable hunting, while anti-whalers argue that populations are over-inflated and outdated by the IWC and that the method used to kill whales is cruel and agonizing. So, I ask: how does a whaling vessel take down a whale, and could it be considered cruel? The pain and suffering of “for-food” animals is always taken into consideration when devising standards and methods for their slaughter. Even the mice and guinea pigs that I work with in my lab have very strict codes for their care and sacrifice, which are regulated and reviewed by animal care committees. Inhumane and painful deaths are not allowed even for these rodents. Shouldn’t we determine the same standards of care for the much more intelligent whales? (More under the fold….)

The International Whaling Commission states:

During the past ten years both Japan and Norway have made major improvements in their whale killing technology. This includes advances in the triggering mechanism for the explosive grenades used in the minke whale hunts, and the introduction of an improved explosive material, penthrite, which has greater power than the traditional black powder. These improvements are such that they are now also being introduced into the aboriginal subsistence whaling hunts in Alaska and Greenland. Any assessment of the efficiency, usually measured by the time to death in the whaling operations, relies on a somewhat subjective indication of insensibility and death. There is still a need to relate the cause of death to the observed time to death, as well as the collection of information on the physiological status of hunted animals.

(Emphasis mine.)

Essentially, what they are saying is that while explosive harpoons are agreed upon to be effective and lethal, whether or not they are humane or quick is still not known. In addition, with explosive harpoons are recommended, they are by no means the only method used. Methods described here in the 2003 Report of the Workshop on Whale Killing Methods and Associated Welfare Issues in Berlin listed hand-held harpoons, cannon harpoons, aboriginal dart guns, and even rifles shot at whales.

In this report is also a lot of whining from Japan about the cost of the explosive-tipped harpoons, leading me to believe that they may not be enthusiastic about using them. The “Norwegian grenades” are the explosive harpoons.

As Japan had stated that one of the most important factors for not introducing the Norwegian grenades in the
Japanese hunt was cost, Germany commented that though this might be a consideration in commercial whaling
activities, scientific whaling operations should use the best available techniques irrespective of their cost. Japan replied that in principle it agreed that one should always use the best available alternative and had therefore tested the Norwegian grenade. However if an alternative device could show the same results, they would adopt the less expensive one even if it is scientific research.

Also from the report, where TTD = time to death, was info about aboriginal methods of whaling in Greenland:

In the harvest from 3 to 100 bullets were used per whale. In the 2002 harvest season, an average of 52 bullets were used per whale, an improvement over the 2000 harvest (average 64 bullets per whale) and 2001 harvest (average 54 bullets). In 2002, the average number of darting gun projectiles used on the gray whales was 2.7 projectiles per whale shot by darting gun. The maximum estimated TTD for gray whales was 56 minutes, and for bowhead whales 53 minutes. Mean TTD for gray whales was 32 minutes, and for bowhead whales 41 minutes.

In addition, a few months ago, a film which followed a Norwegian whaling expedition was released, exposing the cruelty of current whaling methods.

The footage – filmed by investigators from the World Society for the Protection of Animals (WSPA) and the Environmental Investigation Agency – is of the slaughtering of a minke whale by a Norwegian vessel, in defiance of an international agreement.

Although it was hit by an explosive-tipped grenade in good hunting conditions, the whale took more than two and a half minutes to die. Campaigners say this proves that whaling can never be carried out humanely. In less good conditions, where it is harder to aim harpoons accurately, many whales take 10 minutes or more to perish.

Leah Garcés, WSPA’s director of campaigns, says: “Despite this hunt taking place in optimum weather conditions, the kill is not instantaneous. This would not be an acceptable ‘time of death’ for a farm animal, so why should it be permitted for whales?”

Obviously, while explosive harpoons are preferred, this is not a standardized whaling practice. But, more disturbingly, even the most effective method has still no data to back up whether it is humane. This distinction would never be allowed in any other slaughtering practice, so why whales?
