Orca shows will resume Saturday at the three SeaWorld parks in Orlando, San Antonio and San Diego.
But trainers will not be allowed in the water with orcas (also known as killer whales) while officials continue their review into the death of an experienced trainer at the Orlando park. Dawn Brancheau, 40, was dragged under the water by Tilikum, a 12,000-pound male orca.
The shows had been suspended since Wednesday.
Dine with Shamu, a separate show that followed each orca show at Shamu Stadium, has been indefinitely suspended, said SeaWorld.
SeaWorld CEO Jim Atchison spoke Friday at a press conference in front of a window showing the killer whales swimming in a large tank at SeaWorld Orlando.
"We are reviewing all our protocols, training and care of the animals. We have called in experts, and we will make some changes in how our trainers interact with the whales," Atchison said.
Atchison said Tilikum would remain at the park, although he did not say if Tilikum would perform in front of audiences again. There are eight orcas at SeaWorld Orlando, and a total of 25 at the three parks.
Brancheau died of multiple traumatic injuries and drowning, according to Orange County Sheriff investigators.
