Animal rights groups in Singapore are calling on Resorts World Sentosa to release the dolphins from its marine park back to the wild, according to media reports.
The Society for the Prevention of Cruelty to Animals said a bottlenose dolphin named Sharmila died on May 11 at Resorts World Sentosa, which originally acquired 27 dolphins for its marine park. Three others have also died it said.
RWS acquired the animals from the Solomon Islands in the South Pacific between 2008 and 2009 and sent them to the Philippines to be trained while the marine park in Singapore was being built.
Resorts World Sentosa is owned by Genting Singapore, part of Malaysia’s Genting Bhd.
The company told Agence France Presse that two had died in 2010 from a water-borne bacterial infection while at the Malaysian resort island of Langkawi, while another died in November 2012 due to an infection aboard a flight to Singapore.
Resorts World’s Marine Life Park claims to be the world’s largest aquarium with more than 100,000 marine animals from more than 800 species. The park is one of the key non-gambling attractions at the luxury casino resort.
The company said its non-gaming business saw record revenue growth of 6 percent in the first quarter, with its attractions seeing average daily visitation of 16,000.
