Pros and Cons of SeaWorld and other Aquariums


-A great learning experience for customers and researchers.

-A wonderful source of entertainment.

-Boosts the economy through tourism.

-Survival rates of the young are higher.

-Medical attention is given to orcas who appear sick.

The chance to see a killer whale in person is unlikely, so aquariums like Sea World open a door for people that wouldn't normally be opened.

The healthcare given to the orcas makes the survival rates of the calves increase.


-Physical strain

-Mental instability

-dangerous for trainers

-Orcas who aren't sold are killed.

-Capturing methods of wild orcas are unethical.

The small space available to the orcas and the mental strain of performing the same tricks everyday are possible causes of the limp dorsal fin.

The orcas that are bred in places like Sea World are sold and transported, but those who are not sold are killed.

Not only do the orcas suffer from the confinement, but the trainers are put in harms way.

It is believed that the noise from the filtering system in the pool distracts and irritates the orcas.

The Issue

Trainers are dying and the orcas are being neglected.  

The Impact

This damaged the marine training industry, and exposed the morals behind training marine mammals. The treatment of animals has come under scrutiny by the public because of the issues that Blackfish illustrates.

What is being done?

Blackfish brought awareness to the issue in recent years. By building awareness, people were able to see the good along with the bad. An easy solution would be to shut down places like sea world, but they generate so much revenue that shutting them down would affect the economy.


On February 21, 1991, Sealand trainer Keltie Byrne fell into the pool containing all three orcas. She was pulled to the bottom of the enclosure by Tilikum, tossed around among the three orcas, and ultimately drowned. It took Sealand employees two hours to recover her body from the orcas.

Tilikum scalped and dismembered Dawn as well as breaking bones throughout her body before drowning her.

It is believed that Danial Dukes slipped into the pool after hours and drowned. He was found the next morning draped over Tilikum's back naked.
