No one was injured. Activist Paul Watson of the Sea Shepherd Conservation Society said his boat was chasing the Japanese ship dragging a whale on board when another Japanese boat shot in front of his vessel, causing a collision. "The situation down here is getting very, very chaotic and very aggressive," Watson told The Associated Press by satellite phone from his boat, named after the late Australian conservationist and TV personality, Steve Irwin. Earlier in the day, Watson said, the Japanese hurled pieces of blubber and whale meat at his ship. "We can see the blood pouring out by the barrel," he said as he watched the Japanese haul another whale onto their vessel. In a statement, the Institute of Cetacean Research _ the Japanese government-affiliated organization that oversees the hunt _ condemned the protesters' actions, characterizing the collision as a "deliberate ramming" that occurred while the Japanese were trying to load a whale on board one of their ships. Shigeki Takaya, a Fisheries Agency spokesman for whaling in Japan, called the incident "appalling and unforgivable." "We will ask concerning countries, including Australia, to immediately stop them from carrying out such horrendous acts," Takaya said. Japan plans to harvest up to 935 minke whales and 50 fin whales this season.
