With financial support from Greenpeace, humpback whales have been tagged by the Cook Islands Whale Research and Opération Cétacés. The satellite tagging, skin biopsies and photo identification has already provided a huge amount of information about the migration patterns of threatened humpback populations. The "scientific whaling" carried out by the Japanese government does not address the most important needs identified by the International Whaling Commission, and can not be seen as justifiable. This year their quote includes 50 humpback whales.

Immortal whales? Japan's whaling is a hoax
Japan's first ‘scientific’ whaling program, called JARPA, spent 18 years and killed 6,778 minke whales attempting to determine the natural mortality rate, M. In 2006 an expert workshop of scientists from the International Whaling Commission, meeting in Tokyo, agreed (including the Japanese scientists) that the natural mortality rate was not determined - the confidence limits around estimates of M from JARPA data were so wide that M remains effectively unknown. These were so wide that even a value of M=0 was not excluded.
