UNEXSO(underwater explorers society) started a program back in the mid 80's in Freeport Grand Bahama Island, I was amazed at the number of cruise ship people they brought in, they moved them to a private caye and had all kinds of programs like dolphin trainer for a day, they got to the point after a few years where they would take them out in the ocean & have small groups 6 divers dive with them for about $120 per person, it was always in a sandy area with no reef around.
They would video everything & sell the videos.
At the time I believe this was thier biggest money maker.They did shark feedings the same way with video. I never participated in the dolphin program because I did'nt approve of it,I did many of the shark feeds it was a real rush.
I was there a couple of years ago and their diving programs has really dropped off,
Neal Watson has taken over the shark dives as well as most of the diving on the Island.
The only thing keeping UNEXSO going was the dolphins.I did my Naui Instructors Training there in 1990 & learned much about their operation.
Again I do not approve of the dolphin program,but I know they made a ton of money off them,They were taking about 120-150 tourists a day at their peak,mostly to watch them do tricks & swim with them for extra cash.
