Barracuda and Jack's are great fish for eating.
Today we took the small boat out for a quick trip and pretty close to shore we hooked small tunas, rainbow runners, Spanish mackerel and a very good size snapper, so you definitely have a chance for lots of different fish from shore, also for eating.
But it is fishing, not catching, so it all depends on the tide, the moon, the right or wrong lure, time of day and lots of luck
