This simply is not possible. This particular stingray could die from the stress of being re-introduced to the ocean, but I doubt it and it would absolutely not affect it's environment in the gulf. Releasing a native fish back into it's environment would have no adverse effect. I'm not advocating it, but the danger is to the specimen in question not it's natural environment.
The danger is releasing non-native fish, and not because of a mystery virus that kills everything. The danger is those fish not only survive, but thrive and change the balance of the ecosystem. There are presently at least 16 non-native fish species thriving off the FL coast, including yellow tangs. This is currently being studied to see whether this will have an adverse affect or not.
