Japan's Scientific Whaling
The general objectives of the Japanese research programme in Antarctica are stated to be to estimate biological parameters for stock management and to elucidate the role of the minke whales in the ecosystem. The determination of age-specific natural mortality rates of minke whales has been the most important specific objective. Determining stock identity and general biological parameters are other important parts of the research.
The main aim of the North Pacific research is to investigate stock identity using genetic studies, measurement of parasite and pollutant burdens, morphometrics and allozmye studies. The Japanese wished to prevent any unnecessary restrictions on catch quotas in their traditional whaling grounds which might arise through inappropriate stock boundaries.
The Japanese Antarctic research programme has faced considerable methodological difficulties which have resulted in the primary focus being changed from estimating age-specific natural mortality, to the less ambitious one of estimating average natural mortality rates. This is for a variety of reasons, including that it has proved impossible to take a truly random sample of whales because of the age and sex segregation of minke whales in both time and space. Large groups of whales have proved easier to sample than small groups or individuals and difficulties with ageing techniques have added to the problems. The confidence which can be placed in any results therefore remains in question. Many of the problems which have been encountered were raised by other scientists on the Scientific Committee during discussions of the research proposals but largely disregarded by the Japanese.
Stock identity studies using genetic techniques have provided valuable information on the populations of whales in both the Antarctic and the North Pacific. However, this information could have been obtained using non-lethal biopsy techniques.
The efforts the Japanese have made to develop their lethal research methodologies are in contrast to the limited effort placed in developing non-lethal alternatives such as biopsy sampling. The higher costs of non-lethal research, where costs cannot be recouped by the sale of products have influenced this.
None of the Japanese research results to date have been used either to improve upon current management plans or to develop new plans. Only the stock identity work, using information from genetic studies, is being used in implementation simulation trials with the Revised Management Plan (RMP), the IWC's current approach to the management of whaling.
Therefore, none of the scientific whaling programmes fulfilled the IWC's criteria. Despite substantive criticisms, many of which have been shown to be valid in retrospect, the research programmes have gone ahead with little modification. The IWC and the Scientific Committee have not taken control of the scientific whaling programmes to ensure their quality. In part this is because the Scientific Committee have been unable to institute mechanisms of review which would be generally considered consistent with good science - those involved in the research are part of the review and thus even basic standards of impartiality are not met.
Illegal trade in whale meat has taken place in the space created by sales of meat from the scientific catch. What the impacts of illegal sale of whale meat on other stocks of whales maybe, or how the research funding is influencing the Japanese research away from non-lethal methods has not been considered during the Scientific Committee's review process.
