TOKYO (AP) — Japanese fishermen have finished killing about 40 dolphins targeted for their meat as part of a larger group trapped recently in what activists say was the biggest roundup they have witnessed in the last four annual hunts.

Sea Shepherd, best known for its anti-whaling activities, said that of roughly 250 captured dolphins, the fishermen first selected 52 to keep alive for sale to aquariums and other customers. They included a rare albino calf and its mother.
