these kills take place (see chapter 8). The significance of these variables <strong>and</strong> the inadequacies of themethods used result in the poor TTDs <strong>and</strong> IDRs that are commonly reported (see chapter 6).The proximity of the vessel <strong>and</strong> the gunner to the whale is variable <strong>and</strong> is often far from optimal.The optimal distance for euthanasing a large cetacean, as demonstrated during the euthanasia ofstr<strong>and</strong>ed cetaceans, is likely to be no more than an arm’s length. During many whaling operations,the gunner must aim at a moving target, surrounded by a moving sea <strong>and</strong> from a moving platform(chapter 8).There is also growing concern that the active pursuit of whales, may force the escaping cetacean toundertake a degree of exertion for which it is not evolutionarily adapted. This may induce what isreferred to as ‘exertional myopathy’, which may manifest as lethal or sub-lethal disease ordysfunction. Thus, whales that are pursued, but avoid being struck <strong>and</strong> eventually evade capture,may suffer as a result of this pursuit. It is also possible that some may die as a result of inducedexertional myopathy.As a result, even if more efficient <strong>and</strong> more species-specific technology could be developed for killingcetaceans on the high seas, the fact that there may always be a percentage of whales that are eitherstruck <strong>and</strong> lost, or that are pursued <strong>and</strong> lost without being struck, would remain a serious welfareproblem.Problems associated with the specific biology of whalesAs described in chapter 4, cetaceans are unusual animals <strong>and</strong> their biology raises ethical as well aswelfare concerns. We still know relatively little about many whale species. This lack of knowledgeincludes a poor underst<strong>and</strong>ing of where many populations begin <strong>and</strong> end, <strong>and</strong> even of basic cetaceanbiology <strong>and</strong> behaviour. Where knowledge is adequate, it is apparent that some species – for example,orcas, sperm whales <strong>and</strong> pilot whales – have highly developed social structures <strong>and</strong> there is a stronginterdependence between individuals. Skills <strong>and</strong> specialisations can be seen to pass betweengenerations <strong>and</strong>, these animals can be said to have cultures as well as societies. This means that theremoval of individuals by hunting may have a significant impact on the wider population becausetheir potential to pass on knowledge (as well as genetic diversity) is removed. Similarly, the removalof entire groups or populations may mean the removal of entire ways of life or cetacean cultures.WHALING & WELFARE127Because they are adapted to an exclusively marine way of life (cetaceans being the larger of only twoorders of mammals that complete their lifecycles in the water), these animals also have a number ofphysiological <strong>and</strong> anatomical peculiarities that further compound welfare issues.Determining when whales are deadPerhaps the greatest concern relating to the welfare of hunted cetaceans is the fact that the currentcriteria used for determining death in cetaceans are inadequate (Butterworth et al. 2003) (see chapter11). It is likely that whales suffer more prolonged deaths than the current data suggest, but until ascientifically proven means of determining death in cetaceans is established, individual whales may bedeclared dead while they are still alive. In some cases, it is possible they may even die while beingwinched aboard a processing vessel. It is also possible that an individual whale could be paralysed bythe harpoon strike <strong>and</strong> may initiate a physiological dive response, in an attempt to escape this attack.Such an animal would then present as ‘motionless’ <strong>and</strong> not breathing (since it may be holding its
eath). Using the current criteria this whale could then be recorded as dead <strong>and</strong> be hauled on to theflensing deck whilst still alive.The IWC criteria tend to be used in an exclusive fashion by whaling nations i.e. the presence orabsence of a single measure is used, rather than the inclusive assessment of several criteria, as iscommon practice for assessing death in other species. Furthermore, Japan typically uses motionlessas the main criteria for determining death, although this is not, in fact, one of the IWC criteria(chapter 11).Many species of cetacean are adapted for extended dives (Anon 2003) (see chapter 4) <strong>and</strong>consequently harpoon strikes to the thoracic region (which might be considered lethal for terrestrialmammals due to the injury caused to the lung <strong>and</strong> heart tissue) may not have the same immediateeffects for cetaceans, due to their capacity for functioning using tissue-stored oxygen reserves.128A REVIEW OF THE WELFARE IMPLICATIONS OF MODERN WHALING ACTIVITIESThe ‘special case’ of special permit whalingJapan continues to issue special permits for the killing of whales in scientific research programmes.However, there has never been unequivocal approval of any of these research proposals by the IWC’sScientific Committee. Furthermore, the Commission has expressed considerable concern throughseveral resolutions on scientific whaling, including, most recently, a call on “the government of Japanto halt the JARPA program, or to revise it so that it is limited to non-lethal research methodologies” 4 . Acritique of one such programme, the ‘JARPN’ programme, by a number of scientists from theScientific Committee during the 2002 Annual Meeting (IWC 2002b) revealed that:• there are no meaningful quantifiable measures by which to judge the research;• lethal sampling is not essential to the research, as biopsy sampling could provide genetic <strong>and</strong>dietary information;• Japan describes JARPN II as a “multi-species modelling approach to whale management”; yet no suchapproach has been agreed by the Commission.Concern was further reflected in the statement submitted by 40 scientists from the ScientificCommittee to the 55th Annual Meeting of the IWC in Berlin, in response to Icel<strong>and</strong>’s proposal toinitiate special permit whaling:“The proponents have failed to supply adequate justification for the proposed sample sizes, <strong>and</strong>have offered no performance criteria for how the work’s ‘feasibility’ will subsequently bedetermined”.Also:“We reiterate that the major objectives of the Icel<strong>and</strong>ic proposal are either not relevant to themanagement of whales under the Revised Management Procedure (RMP), or that the subset ofinformation which is relevant ... can be – <strong>and</strong> routinely are – obtained with far greaterefficiency by well-established non-lethal methods”.And:“As members of the Scientific Committee, we are seriously concerned by what we see as theincreasingly frequent abuse of Article VIII of the International Convention for the Regulation ofWhaling by some member nations. This has important ramifications for the IWC <strong>and</strong> the workof the S.C. Member governments that promote poorly conceived research whaling programmesplace their scientists in the untenable position of having to defend these proposals in order tosupport the agendas of their governments” (IWC 2003b).
