The current generation of orcas will be the last in the company’s care. SeaWorld is also introducing a new aquatic environment for the existing animals with the change set to start in San Diego park next year followed by San Antonio and then Orlando in 2019.

Joel Manby, president and chief executive of SeaWorld Entertainment, said: "As society’s understanding of orcas continues to change, SeaWorld is changing with it.

"By making this the last generation of orcas in our care and reimagining how guests will encounter these beautiful animals, we are fulfilling our mission of providing visitors to our parks with experiences that matter."

The current population of orcas at SeaWorld will live out their lives at the company’s park habitats.

Wayne Pacelle, president and chief executive of Humane Society of the United States, said: "SeaWorld’s commitment to end breeding of orcas is a long-held goal of many animal advocacy organizations, and we commend the company for making this game-changing commitment."

The announcement comes after years of pressure from animal rights groups. SeaWorld has faced a particular struggle at its San Diego park, where in recent years visitor numbers have fallen.

The allegations made by the documentary Blackfish had a particularly damaging effect for the company, although SeaWorld did dispute many of the findings.
