The term "мормышка" refers to a small fishing lure commonly used in ice fishing and freshwater angling. It is typically made of metal and designed to resemble small aquatic creatures, attracting fish such as perch and roach. The shape and weight of the мормышка allow it to sink quickly, making it effective in various water depths. Mormyshka fishing is popular in countries like Russia and Ukraine, where anglers often use it in combination with live bait or artificial flies. This technique requires skill and patience, as the angler must carefully manipulate the lure to entice fish to bite.
