Louie-
Here's my 2 cents, for what it's worth. Florida is full of very tasty saltwater fish. Largemouth and peacock bass are decent to eat. In my opinion, at best, good frying fish. I would leave them for someone else or for you to catch another time. CPR - Catch, Photo, Release.
Additionally, I would be a little concerned about run-off in the canals. There's bound to be a fair amount of herbicides, pesticides and other chemicals. FWC may test these waters, since they have become a popular fishery, but I don't know for sure whether or not they do.
