Marine animals | Hunting AC IV: Black Flag Guide

Each one of the five big fishes is to be encountered in two spots in the Caribbean. The exception is the Bull Shark that can be found in four of them. This is how many times you need to hunt for each of the fishes to be able to craft all of the upgrades that require the trophies which you won on them. The map gives you spots where you can find each fish, right at the beginning. After the first hunting, the fish changes its location. The new spot where you need to hunt for it is near the previous one. This way, the fish cannot leave the area assigned to it. In other words, there is no such situation in which the Great White Shark from the South of the map moves over to the North, after several hunts.
