Occasionally a good size monster. Line fishing is good for snapper at the river. I spend from 3 to 5 hrs per day snorkeling. This is just scouting the area. I see simply incredible things this way.
Sleep is irregular as one gets up twice per night to check the nets and fishes all day.
I'd like to mention Moray Eels. They resemble a huge snake with the head of a barracuda. They are vicious when approached improperly. Pretty useless for spearing fish. But great for poking around.
