Dolphins have been herded into a cove as part of an annual hunt in the Japanese seaside town made famous by an Oscar-winning documentary about their slaughter, conservationist group Sea Shepherd said Friday. A town official said none were killed. The dolphin hunt at Taiji, documented in “The Cove,” begins Sept. 1 every year. The boats returned empty Wednesday. But on Thursday, some dolphins were corralled into the inlet, according to anti-whaling group Sea Shepherd and a fishing official in Taiji. The official in charge of media queries at the Taiji fishing organization said a handful of dolphins were kept for aquariums, but the rest were set free Friday morning. He declined to give details. He said the criticism the town has received from the West was unfair because residents were merely trying to make a living, and the rocky landscape made it difficult to go into farming or livestock. Sea Shepherd said it has been monitoring Taiji with a small crew of Australians, New Zealanders, Americans and Japanese this week.
