Once you have reached the correct fishing spot, you will see the fishing icon on the top right of the screen. Press the fishing button (O/B) and select your bait of choice. You can refer to the above table for the required bait. A line is automatically cast once the bait is selected.
Wait for the fish to bite. You observer some smaller bites initially. When the rod bends significantly, (observed normally at 3rd bite), press O/B to hook the fish. After that, pull back the left stick opposite to the direction of the fish movement.
