SAN DIEGO (AP) — Animal rights activists applauded SeaWorld's plans to end its orca shows at its San Diego park but said the company should phase out its captivity of killer whales altogether. SeaWorld Entertainment Inc. announced Monday that it will end orca shows at its San Diego park after visitors at the tourist attraction made it clear they prefer seeing killer whales act naturally rather than doing tricks. CEO Joel Manby told investors the park — where the iconic "Shamu" show featuring killer whales doing flips and other stunts debuted decades ago — will offer a different kind of orca experience focusing on the animal's natural setting and behaviors, starting in 2017. SeaWorld earlier this year announced plans for a $100 million expansion of the killer whale tanks in San Diego to boost attendance, but the California Coastal Commission made approval of the project, dubbed "Blue World," contingent on SeaWorld agreeing not to breed, transfer or sell any of its captive orcas at the park.
