Individuals can purchase a fishing license at a license issuing agent location, online, or over the phone. Those 16 years of age and older will need to obtain a fishing license for catching freshwater fish species by “angling, spearing, hooking, longbow, and tip-ups," and if they are catching frogs and baitfish in any particular manner. Fees for licenses depend on the type (annual, seven day, one day) and whether or not you are a resident. Fees are reduced for active duty military, veterans, senior citizens, legally blind individuals, and non-resident students attending a New York State college or university full-time.
