Teach a man to fish VS Teach a fish to beg?

Many of us would have read about the quote, Give a man a fish he eats for a day and teach a man to fish he eats for a lifetime.
Now Resorts world Singapore is doing the opposite. They capture a healthy fish who knows how to find food for itself in the wild to do silly stuns to beg for food!
The dolphin would be kept hungry, and each time it does what its told it gets food. Has anyone taught how the dolphin would feel?
Dolphins have a lifespan of 45 years in the wild and just averaging 25 in captivity, excluding those who die shorty after they have been captured.
Is our entertainment really worth their freedom?
