The Kagoshima Aquarium (ja:いおワールドかごしま水族館, Io World Kagoshima suizokukan) is a Public Aquarium of Kagoshima City located in Kagoshima Prefecture Kagoshima City Honkoshinmachi.

History

Opened on May 30, 1997.[1][2] The Kagoshima coast, which is washed by Kuroshio, and Kagoshima Bay marine life are mainly exhibited, but brackish water and river life are also handled. The specialties are whale shark (Yuyu) and Satsumahaorimushi. The Japanese name "Io" is Kagoshima dialect and means fish.[3] Total project cost is about 12.7 billion yen.[2] The appearance is an image of Stingray.[2] Kagoshima Aquarium is the first aquarium in Japan to successfully feed Chinese sturgeon and display under salt water.[4] In October 2011, the number of visitors reached 10 million.[5] At the end of the route, the "Sea of Silence", which was conceived by the first director, Hiromasa Yoshida, is displayed along with the text. The creatures are not exhibited inside and are filled only with water, but it is said that this is to make people think about the marine environment.[6]

Whale shark "Yuyu"

The Kagoshima Aquarium has a large Kuroshio tank with a water volume of 1,500,000 litres (396,000 US gal), but it is not large enough to captivity whale sharks that easily exceed 10 m (33 ft) when grown.[9] Therefore, the Kagoshima Aquarium is exhibited and captivity by the "Kagoshima method", in which training is conducted to return to the wild before the body length reaches 5.8 m (19 ft), and then returned to the wild. A transmitter is attached to the whale shark that returns to the sea, and it has been successful in grasping the migration route of the whale shark.[10]。

The whale sharks raised in the Kuroshio Tank have been called "Yuyu" for generations and are gaining popularity among visitors.
