A method for a dual-bearing reel includes detecting a rotational speed of a spool rotatably mounted to a reel unit, a fishing line to be wound about the spool, controlling a spool brake to brake the spool with a first braking force when a detected tension that acts on the fishing line is equal to a reference tension, controlling the spool brake to brake the spool with a braking force obtained by correcting the first braking force based on a second braking force when the detected tension and the reference tension are different from each other, the second braking force positively or negatively correcting the first braking force by increasing or decreasing the first braking force, and performing a decrease processing of decreasing the second braking force with the elapse of time when the second braking force has been determined to fluctuate with a predetermined amplitude or greater.
