This study seems to show that training by humans to perform in shows had a negative effect on juvenile orcas.

>From 1979 to 1980, however, we were able to interact with juvenile orcas in an unstructured way at San Diego’s SeaWorld facility. We observed in the animals what appeared to be pranks, tests of trust, limited use of tactical deception, emotional self-control, and empathetic behaviors. Our observations were consistent with those of a former Seaworld trainer, and provide important insights into orca cognition, communication, and social intelligence. However, after being trained as performers within Seaworld’s commercial entertainment program, a number of orcas began to exhibit aggressive behaviors. The orcas who previously established apparent friendships with humans were most affected, although significant aggression also occurred in some of their descendants, and among the orcas they lived with.

Interesting. Sounds like they hate that kind of work. Or maybe it makes them more competitive.

Now I almost feel less disturbed about a prison that puts on a rodeo in my state.

Rodeo is animal abuse so I don’t support that. But otherwise it’s good for prisoners to have something to do. I have read about programs where they train dogs. If i was in prison I’d be happy to do that.
