The fishing mini-game is an important part of Breath of Fire III. Not only are you required to take up fishing to progress in the story, it can also give you access to rare items, accessories, armour and weapons through the use of the Manillo Trading Shop.
To start fishing you will need to buy a rod and bait, which can be purchased in the first item store you find, located in the McNeil village. As you progress through the story, you can also find many different types of rods and bait that are spread throughout the game.
Once you have the necessary fishing equipment to start the fishing mini-game, you will need to find a fishing spot. There are many different fishing spot locations throughout the game where you can catch a wide variety of different fish. The fishing spot locations are easily identified by a fish jumping out of the water on the world map.
