Reefman...I am a bit further north of you but am looking to collect CUC and other items on the west coast...Sarasota to Ft. Myers or in the KeysAs SMSREEF said, saltwater fishing license and look over the regulations. The only really big reg for you maybe the total number of some species and total over all collection of 20 animals per day per person.
I'm with SMSREEF here as well. I've never tried the area. But since I have already driven several hours to get from my house (Cape Coral) to the east side of the state, I might as well drive a couple more hours to great snorkeling in the Keys. But if you find a spot, please, please, please let us know so we can advise others. Good luck.
