SeaWorld said on Monday that it planned to phase out next year its San Diego killer whale performance, a central point for criticism of how its animals are treated.

The company, which also has parks in Orlando, Fla., and San Antonio, said in a company document posted on Monday that it would replace its theatrical Shamu show in San Diego with an “informative” experience that has a “conservation message inspiring people to act.”

The announcement does not affect shows with orcas at the parks in Texas and Florida, said Fred Jacobs, a company spokesman.

SeaWorld has been under heavy scrutiny since “Blackfish,” a documentary that criticized the park’s treatment of orcas, was released in 2013, and attendance has suffered.
