Hopefully someone will respond with better info than this but fishing along the Caribbean side of Placencia from shore wont be very good. You have about 20 ft of sand bottom then its all turtle grass in about 6 to 12 inches of water, the beach is very beautiful and if you could get out on a long dock things could be much better. Wading out could also be possible but Placencia is about 16 miles from the Barrier reef so you have waves and a bit of surf to deal with. Deep sea would be past the reff but plenty of ocean in front. The South end of the Village has a deep water channel but it is busy, I have snorkled it and never seen a fish, but night fishing could be good, just dont know. I would suggest getting a guide and a boat. Or staying on one of the Cayes for a few days of fishing. Most game fish are Barricuda, Tatrpin, Bonefish and Permit..snapper which I like the best because I just want good eating fish. Good Luck.
