This is more about the whale sharks in the nets in Japan.
Whale Sharks in Okinawa Bay.
Thanks to Ollie Lloyd for text and photo.
500 feet off the Okinawa Bay, the Okinawa Churaumi Aquarium keep an open water netted enclosure of 30m diameter and 20m depth housing juvenile and grown whale sharks. The sharks kept in the nets are from the Aquarium's rotation system, where the sharks are moved to the nets when they have had a suitable amount of time living at the aquarium and then are eventually moved back, much like a resort or spa. New whale sharks captured for the aquarium are also living in the nets. The aquarium company offers free diving with the Whale Sharks within the nets.
