SeaWorld, which has suffered a decline in attendance since the documentary "Blackfish" called into question its treatment of killer whales, says it has been told the Department of Justice will not pursue any action on the film's allegations.

According to a filing SeaWorld Entertainment Inc. made with the Securities and Exchange Commission, the company said Justice officials told them " that it does not intend to take any action against the Company or any individuals in connection with the investigation previously disclosed by the Company concerning disclosures and public statements made by the Company and certain individuals on or before August 2014 and trading in the Company’s securities.

"The Company considers the DOJ matter concluded."

"Blackfish," released in 2013, helped sway popular opinion against keeping killer whales in captivity at SeaWorld parks.

In 2016, the theme park said it would phase out shows featuring orcas and stop breeding them in captivity.
