Spin fishing is an angling technique where a spinnerbait, a type of hybrid fishing lure with at least one freely rotating blade, is used to entice the fish to bite. When the line is reeled back, the spinnerbait blades will spin passively with the oncoming water flow, in turn stirring up a significant amount of turbulence and noise, which transmit through the water and provoke predatory fish to strike the lure out of their foraging as well as territorial instincts. Spin fishing is used in both freshwater and marine environments.
