end the hunts. He feels that outside groups do not have a good understanding of Japanese culture which can result in some actions having counter-productive results. In January 2010, it was revealed that the Japanese whaling fleet was chartering flights in Australian planes from Hobart and Albany to track the Sea Shepherd ships' movements and provide information on their location to the whaling fleet so the fleet could evade them. The flights were heavily criticised by the Australian Greens. On January 6, 2010, the anti-whaling ship MY Ady Gil suffered severe damage to its bow after a collision with the Japanese whaling ship Shōnan Maru No. 2. The Ady Gil was abandoned and left to sink after it had taken on too much water to be towed. While the first officer of the Bob Barker has said that all the fuel, oil, batteries and other environmental contaminates were removed from the Ady Gil before towing began, photographic evidence released by the Institute for Cetacean Research showed the wreckage continued to leak fuel into the Southern Ocean after it had been abandoned by Sea Shepherd. Japan's Fisheries Agency announced on April 12, 2010, that the whaling fleet had caught about half of the 935 whales it has hoped to catch during the 2009–2010 whaling research season as a result of obstruction by Sea Shepherd Conservation Society protest operations. The whalers harvested 506 southern minke whales and one fin whale. In February 2011, the Sea Shepherd Conservation Society caused Japan to call off annual whaling in Antarctic waters. Atsushi Ishii, Japanese political scientist and professor at Tohoku University's Center for Northeast Asian Studies stated in his 2011 book Kaitai Shinso: Hogei Ronso ("Anatomy of the Whaling Debate"), that Japan used the activities by conservationists like Sea Shepherd as a face-saving excuse to stop the unprofitable Antarctic hunt. Ishii asserts that the activities of environmental and animal rights activists were actually counterproductive because they fueled nationalism and increased the demand for whale meat in Japan. Ishii predicted that Japan would shift its whale hunting efforts to coastal waters and the Northwest Pacific. In December 2011, The Japanese government confirmed that US$29 million out of their supplementary post-earthquake and tsunami reconstruction budget was spent to provide extra security to ensure the "stable operation" of the Japanese whaling fleet. After a lengthy legal case in the United States, the Sea Shepherd agreed not to harass
