Aim for specific locations around the fishing area, where you can earn bonus experience points or have the chance to catch a rare fish. If you already have an idea about a good spot to fish, grind that location. Reel in very slowly until you get a bite. Then, begin reeling in quickly while watching the tension bar to keep your line from snapping. You need to lower the tension if it turns yellow and orange. Swipe up and down rapidly on the reel to reel in faster, instead of spinning your finger around the reel. This may help catch some of the more difficult fish, but also makes it easier to snap your line. Keep the "Set the Hook" meter filled to get free reel time on a fish without any tension. This is useful when trying to reel in high-ranking fish. Fill the meter against smaller and low-ranked fish by getting the tension meter almost full, and keep it there. Once "Set the hook" is available, it is retained between levels and will be ready when you are going after a big fish.
