Ocean Park Hong Kong is a theme park in the Southern District of Hong Kong Island. Thepark was built with donations from the Royal Hong Kong Jockey Club (now Hong Kong JockeyClub) and opened on I0 January 1977. The park is operated by Ocean Park Corporation, which isa statutory department. It offers affordable marine animal education and entertainment and is a pri-
vate organization for commercial purposes.
In the early operation of the park, the main sources of income for the park were the ticketprices and the funding from the Jockey Club. Since the ticket price was low, most of the time OceanPark was operating under deficit..In 1 July 1987, the government established a 200 million trustfrom the funding of Jockey Club, under the Ocean Park Corporation Ordinance. This separated OceanPark from Jockey Club and became a non-profit organization; it needs to be responsible for its ownincome and was allowed to use commercial means to operate the park.
Since it was permitted to use commercial means to operate, it gradually raised its ticket priceand the deficit turned into profit. In 1992,3 million visitors visited the park. Since 1998, the EastAsian financial crisis, aging attractions, and the passing away of the killer whale; the parkrecorded a deficit for a couple years. Although it was allowed to host 2 pandas in 1999, the num-ber of visitors did not go up and Ocean Park was forced to close its water attractions and the "OldVillage" attraction and turned to bring in more rides in an attempt to capture the youth demand.Together with the opening up of mainland visitors under the Individual Visit Scheme, Ocean Parkrecorded an astonishing 4 million visitors in the year 2004--2005, the highest since the parkopened.
In March 2005, Ocean Park made its redevelopment plan. On 23 November 2006, Ocean
Park held a groundbreaking ceremony for its redevelopment.
