The annual whale expedition off the Japanese port city of Kushiro ended this weekend after having caught 59 minke whales, the Japanese Fisheries Agency said in a statement.

The whales where caught as a part of a research program that whaling opponents claim is just a cover for commercial whaling. A maximum capture of 60 whales is allowed under this research program, which is authorised by the International Whaling Commission (IWC).

The Fisheries Agency says the goal of the hunt was to study the feeding patterns of the whales and their effect on fish stocks. Initial examination of the stomach contents of the killed mink whales revealed mostly pollack, krill and anchovy. The complete results of the study will be presented at next year’s IWC meeting.

Japan also catches about 1,000 whales in the Antarctic Ocean and the northwest Pacific Ocean each year under another IWC research programme.

Minke Whale Facts

· Once perceived as asingle species, the minke whale population has quite recently been recognized as consisting of two distinct species: the Northern Mink Whale, Balaenoptera acutorostrata, and the Southern Mink Whale, Balaenoptera bonaerensis.

· Also known as Little Piked Whales or Lesser Rorquals, Mink Whales prefer icy waters but are found world-wide.

· Balaenoptera acutorostrata is listed as Least Concern on the IUCN Red List of Threatened Species, while Balaenoptera bonaerensi is listed as Data Deficient since it was recognized as a separate species so recently.

· Together, the two species are believed to form a population of over 1 million Minke Whales world-wide.

Norway, one of the two countries that openly defy the IWC ban on commercial whaling, has suspended this year’s whale hunt mid-season after catching less than half the quota of 885 whales. The suspension coincides with this week’s annual IWC meeting in Portugal, but is not linked to the meeting or any adjacent negotiations. Instead, a lack of demand in the Norwegian distribution chain is cited as the reason behind the surprising deferment.

“The number of whales killed so far is enough to meet the known demand,” said Willy Godtliebsen, head of sales at the Norwegian Fishermen’s Sales Organisation (NFSO). “They may resume the hunt later if new buyers turn up.”

According to NFSO marketing director Lise Mangseth, the suspension is an effect of the current financial crisis. The financial situation has dissuaded processing plants from freezing and stocking the meat the way they normally do, in order to save money.

“More generally, [the suspension is due to] organisational problems rather than a problem of demand,” Mangseth said. “The whalers are such small actors and the volumes from the hunt are so limited that the distribution chains don’t really want to invest in their product and there are no marketing campaigns as there are for other food products“.

She also claimed that it isn’t unusual for whalers to take a break during the season.

Greenpeace are interpreting the suspension as a sign of waning consumer demands for whale meat.

“If they don’t start the hunt again later this season, 2009 will be the ‘worst’ year for whaling since Norway resumed commercial whaling”, Greenpeace spokesman Jo Kuper said.

Norway resumed whaling in 1993, despite international protests. When Norwegian whalers were asked to suspend their hunt on Tuesday this week, 350 Minke whales had been harpooned since the start of the whaling season in April. Normally, the hunt would continue until October.

Australia and New Zealand announced Thursday that they will carry out a six-week long non-lethal whale research expedition in the Antarctic early next year. Dubbing the expedition non-lethal is a direct challenge to Japan’s research program that kills up to 1,000 whales a year.

Iceland and Norway are the only two countries openly defying the IWC ban on commercial whaling; Japan is instead using a lope whole that allows for “lethal research”. Whale meat resulting from the Japanese research is sold for human consumption and many critics claim that this is the real motive behind the program.

In a joint statement, Australia and New Zealand announced their intentions to reform science management within the International Whaling Commission, which holds its annual meeting in Madeira, Portugal, next week, and end Japan’s “so-called scientific whaling.”

“This expedition and the ongoing research program will demonstrate to the world that we do not need to kill whales to study and understand them,” said Australian Environment Minister Peter Garrett.

The expedition aims to increase our knowledge of population structures, abundance, trends, distribution, and the ecological role of whales in the Southern Ocean.

During the latest Japanese hunt, which ended in April, 679 minke whales and one fin whale was killed over a period of five months.
