"Divers from the European conservation organisation The Black Fish have last night cut the nets of six holding pens in Taiji, Japan, that were holding dolphins caught during a dolphin drive hunt a few days earlier. During this hunt a number of dolphins were selected for the international dolphinarium trade and transferred to these holding pens. In rough weather conditions the divers swam out and cut the nets of six of these holding pens, allowing a number of dolphins to swim back out to sea."
