I think you've been duped.. sorry..
Very few dolphins are rescued from the wild at all, and of those that are attempted, very few survive and of those that do, barely any are ever released. Look at what dpmmr say in their FAQ about where their dolphins come from...
"All but two of our current dolphins were born right here in the facility. Under the Marine Mammal Protection Act, there are certain provisions that allow wild marine mammals to be taken from the wild. These provisions require extensive permits for research, educational, and public display purposes, or even enhancing survival of a marine mammal species (NMFS). Our original group of dolphins was collected from the Sarasota Bay area in the late 1970s and early 1980s to begin a Natural Swim program at Dolphins Plus Marine Mammal Responder. Over the years, Dolphins Plus Marine Mammal Responder has expanded due to many successful births, and these dolphins make up our current population.
In the past, Dolphins Plus Marine Mammal Responder housed a rescue dolphin named Castaway. She had stranded herself in Castaway Cove, off of Jensen Beach, on the east coast of Florida. Castaway was rehabilitated by the Marine Mammal Conservancy and was moved to Dolphins Plus Marine Mammal Responder in 2007."
So the truth is, they captive breed dolphins, from a population they caught in the wild.
They have two dolphins that they have bought in from other facilities (or they would state they had rescued those).
They have rescued ONE dolphin and claim to have rehabbed her yet she remains captive there.
This is a tourist attraction masquerading as research/science/rescue, nothing more.
