Last year's documentary "Blackfish" sparked a huge outcry over the use of orcas, known as "killer whales", which have been performing at SeaWorld's theme parks for decades. The film details the tragic death of orca whale trainer Dawn Brancheau who was killed at the SeaWorld theme park in Orlando, Fla. after being pulled into the tank by a killer whale.

In response, Assemblyman Richard Bloom sponsored legislation today to end the practice of using orcas for performances at theme parks. The bill does not call out SeaWorld by name but the San Diego park is the only venue in the state that uses orcas for entertainment.

The bill seeks to permanently end the use of performing orcas in theme shows, ban captive breeding and prohibit the import and export of killer whales. It would also require that all current captive orcas be retired to sea pens, if available, and not used for performances.

Animal rights activists have been calling on SeaWorld to stop using orcas for performance because of concerns over the whale's well being and the safety of trainers.

In a statement, SeaWorld dismissed the legislation and said that it  already operates under multiple federal, state and local animal welfare laws. Is banning the ‘killer whale’ shows
