In August 2014, SeaWorld announced it planned to build new killer whale tanks that would be almost double the size of the existing ones to provide more space for its whales, scheduled for completion in 2018. The company maintained the move was not in response to the release of the "Blackfish" documentary. Wild killer whales may travel up to 160 kilometres (100 mi) in a day and critics say the animals are too big and intelligent to be suitable for captivity. In 2016 it was announced by SeaWorld that they no longer had plans to complete the expansion project. PETA, which opposes whales being kept in captivity has proposed the theme park operator base its whales in seaside sanctuaries. The company also pledged $10 million in matching funds for killer whale research. The plans to increase the size of the tanks in San Diego were put on hold in October 2015 after the California Coastal Commission ruled that the work could only go ahead if they banned captive breeding, which would eventually lead to end of killer whale shows at the park. On March 17, 2016, SeaWorld announced the end of their breeding program, which signifies the last generation of orcas in captivity in their care, though Takara was still pregnant at the time. Theatrical orca shows ended at SeaWorld San Diego in 2017 and ended in Orlando and San Antonio in 2019.
