The allometric growth pattern of 666 common minke whales (Balaenoptera acutorostrata) collected in the North Pacific was investigated by comparing skull length and skull width with body length. For comparison, skull length and skull width in relation to body length were analyzed in 3 Balaenopteridae species (B. musclus, B. physalus, and B. borealis). The generalized linear model was adapted for evaluating the effects of sex and sexual maturity status on growth patterns. The skull proportion of large Balaenoptera whales (B. musculus and B. physalus) showed positive allometry, but that of the common minke whale showed negative allometry, despite being related species. Such differences in intraspecific growth patterns could be the result of adaptation driven by feeding strategy. © The Mammal Society of Japan. Source

Japan has confirmed the killing of more than 300 whales, 200 of which were pregnant females during its latest whaling mission. The announcement was made as ships from Japan's Institute of Cetacean Research, which were in the Antarctic region since December 2015, returned Thursday from a "scientific" expedition, which the ICR claims is being done in the name of science. The Fisheries Agency said that the four-ship whaling fleet has returned to Shimonoseki in southwestern Japan having achieved the goal of taking 333 minke wales, 103 of which were males and 230 females. Of the mature females captured, 90 percent were pregnant. "The number of pregnant females is consistent with previous hunts, indicating that the breeding situation of minke whales in the Antarctic is healthy," the Fisheries Agency said in a statement. Japan's new quota is significantly fewer compared with its annual kill limit of 935 whales in the past. The reduction appears to have been influenced by criticisms and calls against the country's whaling practices. Eating whale is part of Japan's culture and the country has long claimed that most species of whale are not endangered. Its whaling practices though have long been a subject of criticism and its latest decision to conduct another whaling expedition is a defiance of the International Court of Justice ruling that declared the Antarctic whaling illegal. Many believe that Japan's whaling expeditions are not for scientific purpose. Australian Marine Conservation Society Director Darren Kindleysides said that international experts have examined Japan's so-called scientific research and found it was just a guise for killing whales. It appears, however, that the hunts are neither motivated by a market for whale meat. Although most of the meat from whale hunts ends up on shop shelves, many Japanese no longer eat them. Demand and consumption for whale meat per person has declined to just about 50 grams in 2005 from 2,000 grams in 1967 prompting shops in Japan to reduce the prices of whale meat by half in 2009 so as to move stockpiles. Japan plans to take nearly 4,000 whales for the next 12 years as part of its research program. It has also acknowledged looking forward for the resumption of commercial whaling.

It is no secret that Japan continues to send whaling expeditions to Antarctica despite international criticism. As reported by Tech Times, Japan on Thursday confirmed the killing of more than 300 minke whales — 200 of which were pregnant. Ships from Japan's Institute of Cetacean Research returned from an almost four month-long hunting mission under the guise of scientific research. The expeditions, however, are considered defiance of the International Court of Justice ruling which declared that whaling in Antarctica is illegal. Japan's decision to send whaling expeditions has received criticism from different countries. Greg Hunt, Environment Minister in Australia, said the country condemns the act. "We do not accept in any way, shape or form the concept of killing whales for so-called 'scientific research,'" said Hunt. United Kingdom's ministry for environment Defra also expressed its disappointment with Japan's decision. "This undermines the global ban on commercial whaling which the UK strongly supports," the ministry said. But why does Japan do it, anyway? Japan has not ignored the IC Justice ruling, but that doesn't mean it completely followed it either. In November 2015, the country said its "scientific" whaling program will only take 333 minke whales. BBC news reported that the whale meat from the expedition "ends up on the plate." And yet other reports say that Japanese consumers are not really clamoring for it. A Wired report said that the consumption of whale meat in Japan stands at 4,000 to 5,000 tons every year. Consider the fact that Japan consumes about 600 million tons of seafood annually, indicating that meat from the sea mammals occupy "small" place on the country's dinner plate. The nation's whaling program is also quite miniscule. The American Cetacean Society said that the global population of minke whales is currently at more than 1 million. Japan has taken 3,600 minke whales since the launch of its scientific research program. Some experts believe that the 333 minke whales that Japan takes every year is not likely to impact the population of the sea mammals. The Japanese aren't the only ones hunting whales. Norwegian whalers are also hunting minke whales, and their quota is a whopping 1,000 every year. The same goes for Icelandic whalers. According to a paper [pdf] by Keiko Hirata, a political scientist from California State University Northridge, there are two factors as to why Japan's is still pushing through its whaling missions: cultural and political. First, the Japanese do not see minke whales as charismatic sea mammals in need of protection from consumption. Hirata said that in Japanese, the symbol for whale — which is pronounced as kujira — includes within it a component that means fish. "Most Japanese lack any special love of whales and disagree with Western animal rights activists who insist on whales' rights," said Hirata, adding that most of them consider it hypocritical that Westerners kill kangaroos and baby cattle while saying that it is morally wrong to kill whales. Second, maintaining Japan's whaling efforts is an act of maintaining political turf. The expeditions are overseen by the Ministry of Agriculture, Forestry, and Fisheries, and Hirata said if the program is ended, the officials will be out of work. Hirata concluded that Japan is not likely to change its stance in the near future. As of today, minke whales are not endangered. In December 2015, Australia and other countries have challenged Japan over its whaling program, threatening to pursue legal action.
A whale is captured by the Yushin Maru, a Japanese harpoon vessel. This image was taken by Australian customs agents in 2008, under a surveillance effort to collect evidence of indiscriminate harvesting, which is contrary to Japan's claim that More Japan sent two whaling ships back to Antarctica's Southern Ocean today (Dec. 1) after a one-year hiatus, resuming seasonal whale hunts that have come under increasing scrutiny and censure from the international community. Under a revised whaling plan, Japan proposes to kill 333 minke whales this year for research purposes — significantly fewer than past years' annual kill limit of 935 whales. Japan's Institute of Cetacean Research (ICR), which oversees the country's whaling program, stated on its website that researchers will study the whales' fish consumption and measure their competition with fisheries, creating ecosystem models for managing marine resources. "The purpose of Japan's research is science — science that will ensure that when commercial whaling is resumed, it will be sustainable," ICR claimed on its website. However, statements from environmental officials in Australia and the United States express skepticism that killing any whales is necessary for data collection. Greg Hunt, Australia's minister for the environment, said in a statement that the Australian government "strongly opposes" Japan's decision to return to the Southern Ocean to hunt whales. He added that the International Whaling Commission's (IWC) Scientific Committee put forward "significant questions about the science underpinning Japan's new whaling plan, [called] NEWREP-A, which are yet to be satisfactorily addressed." [To Protect Whales, US Diplomacy Needs Teeth (Op-Ed)] From the U.S., Russell F. Smith III, deputy assistant secretary for international fisheries at the National Oceanic and Atmospheric Administration and U.S. commissioner to the IWC, expressed similar concerns. "Japan had not justified the need for lethal whaling to carry out its research," he said in a statement. "Unfortunately, rather than giving itself time to modify its research program to fully address these issues, Japan has decided to restart its program now." Commercial whaling conducted by most countries ended decades ago, following a 1986 ban issued by the IWC, a global organization empowered to manage whaling industries, evaluate threats to whale populations and oversee conservation. But the IWC permits whaling in international waters if the hunt is conducted for research purposes. Soon after the 1986 ban, Japan launched its scientific whaling program, conducted by the Institute of Cetacean Research. According to the IWC's guidelines for the research permits, the Institute of Cetacean Research is allowed to process byproducts of the whaling program, such as whale meat, and sell it for consumption. In 1994, the IWC designated the Southern Ocean as a whale sanctuary, but Japanese officials claimed that their research program provided exemption, even in the newly protected area. The hunts continued, and approximately 14,000 whales were killed between 1986 and 2014, according to the International Fund for Animal Welfare. Australia has long been a vocal critic of Japanese whaling, and in 2008, the country successfully banned Japan's whaling fleets from the Australian Whale Sanctuary in Antarctica. In 2010, Australia went even further, bringing action against Japan in the International Court of Justice to halt the scientific whaling program in its entirety. In 2014, Australia appeared to win a significant victory, as the International Court of Justice found that Japan's "scientific" research failed to meet the standards laid out by the IWC, and the court ordered a halt to the whaling. In spite of the ruling, Japanese whaling vessels Yushin Maru and Yushin Maru No. 2 departed from Shimonoseki Port for the Southern Ocean. Two more ships are scheduled to join them, bringing the total number of crewmembers on the whaling mission to 160. Their work is scheduled to begin later this month, though not without close scrutiny on the global stage. "The United States will continue to engage with the Government of Japan in an effort to address U.S. concerns with Japan's new lethal research program," Smith said. "We believe all of Japan's primary research objectives can be met through nonlethal activities and continue to oppose their scientific whaling programs."

The founder of a radical conservation group made famous by the television show "Whale Wars" says a settlement over anti-whaling activities only prevents the group's U.S. organization from interfering with Japanese whalers in the Southern Ocean. This week, Japan's Institute of Cetacean Research and a whale ship operator announced they'd reached an agreement with Sea Shepherd Conservation Society and its founder Paul Watson. "What it means is Sea Shepherd USA cannot contribute money toward the Southern Ocean campaign, cannot be involved in the Southern Ocean campaign, and that's fine. We've got plenty of other campaigns to do," said Watson, who recently returned to the U.S. and is living in Vermont. But he said the settlement doesn't affect the group's other entities. "Whether Sea Shepherd Australia or Sea Shepherd Global ... if they intend to return to the Southern Ocean that's their business, it's not ours and I can't control them," he said of the settlement filed on Tuesday. The Institute of Cetacean Research, which studies whales, also is paying an undisclosed amount to the anti-whaling group on the condition the money will not be transferred to its affiliates elsewhere, including in Australia, one of the most active in attacking Japanese whalers during their hunts in the Antarctic. Officials in Japan are hoping the funding restriction will somehow limit the extent of Sea Shepherd's activities in Australia. Agriculture Minister Yuji Yamamoto on Thursday welcomed the agreement, saying, "I take it as a positive development that would contribute to the safety of the research whaling fleet." Yamamoto, however, said that Japanese whalers should continue to use caution and be aware that there are staunch opponents of whaling. Sea Shepherd Global media director Heather Stimmler said all of its entities around the world — except those in the United States — will continue to oppose what it believes is illegal Japanese whaling in the Antarctic. The International Whaling Commission imposed a commercial ban on whaling in 1986, but Japan has continued to kill whales under an exemption for what the country says is research. Interpol lists Watson as being wanted in Japan on charges of conspiracy to trespass on a whaling ship and interference with business, and in Costa Rica on a charge of interfering with a shark finning operation. Watson was arrested in Germany but then fled to France when he heard that he would be extradited to Japan. In his home office in landlocked Vermont, surrounded by artifacts from his journeys, the 65-year-old Watson said he will continue to coordinate with other Sea Shepherd entities. He's also writing several books and is involved in future television programs. Associated Press writer Mari Yamaguchi in Tokyo contributed to this report.
