It is probably later than you think,,, even today. But an answer may be as simple as discouraging the tourist inshore bait fishers from taking more fish than can be eaten at one meal,,, ask all the flats guides to promote catch and release,,, and promote some incentive for fly fisher to visit the island... They don't keep or kill fish. They prefer, instead, to drink Bilikins and smoke Cuban cigars.

I'll be happy to discuss my avatar with anyone who knows what it is.
