Three separate companies still run travelling dolphin shows on the main Indonesian island of Java: WSI, Taman Safari Indonesia and Ancol. Together they hold an estimated 72 dolphins in captivity. Most of these animals are constantly 'on the road' but WSI also has a holding facility where more dolphins are kept to replace the animals that die on a regular basis. From the start of the campaign the circus owned by Wersut Seguni Indonesia (WSI) has been of special interest to activists.
