SeaWorld Entertainment said Thursday that the killer whales currently living at its facilities will be its last as it will stop breeding them immediately and phase out theatrical orca shows.The move comes nearly three years after SeaWorld came under pressure for its treatment of killer whales and their trainers in the documentary Blackfish. SeaWorld will turn its attention to “new, inspiring, natural orca encounters” with educational programs emphasizing enrichment, exercise and health with its remaining killer whales, CEO Joel Manby said on a conference call. The orca shows will end in San Diego in 2017, while the San Antonio and Orlando parks will end the shows by 2019.
