Joe Manby, the current CEO of SeaWorld Entertainment, has recently announced that the theme park and entertainment company is overhauling its management team.

The shake-up will include the establishment of a branch that will concentrate on adding more theme parks and expanding the existing locations.

Manby, who took the helm of the Orlando-based organization in March, revealed the changes as the entertainment company tries to recover from dwindling attendance and a falling stock price.

Christopher Dold, Chief Zoologist Officer, will take the lead of the company's zoological team of professionals. He and his team will supervise the entire animals program that supplies comprehensive health care for the marine, as well as the terrestrial animals in the theme parks. They will also assume responsibilities in the operation of the park's animal rescue program.

SeaWorld's problem started when the documentary "Blackfish" was released in late 2013. The film accused the theme park of abusing and neglecting its orcas. As a result, animal rights activists have organized protests and petitions against the entertainment company which are still going on. The group People for the Ethical Treatment of Animals is among those actively protesting against Sea World.

According to Manby, the revamp will help the theme park 'deliver on our strategic priorities."

Majority of the management changes involves the promotion of personnel within the company. For instance, John Reily, who is the SeaWorld San Diego president, is being raised to chief parks operations officer. He is replacing Dan Brown, who is exiting on April 1.

Dold, the new chief zoological officer is replacing Brad Andrews, who will remain as zoological director emeritus.

Marilyn Hannes is now promoted as park president of SeaWorld San Diego and Aquatica, San Diego. She formerly held the position of vice president of global sales.

Lastly, Carl Lum has been promoted to the office of president, SeaWorld San Antonio, replacing Dan Decker who is retiring from the entertainment company with no reason given.
