“Rook is teaming with freshwater river fish. Some are tastier than others, but you can eat pretty much all of them. My father always told me, 'Give a man a fish and he eats for a day, teach a man to fish and he eats forever.' Or maybe it was, 'Stay in the corner or I'm coming over there again.' Anyway, something like that.”

River Fish are animals that populate the rivers of the Rook Islands in Far Cry 3. They are harmless to the player. Killing a River Fish will reward Jason with a handbook entry about the River Fish. Being hard to spot in the rivers, an easy way to kill them is to toss an explosive weapon into the river and explode it.
