The price of a fishing license varies from state to state. For example, a fishing license costs $25 for adult residents of Arizona to purchase an annual fishing license. In Ohio, adult residents pay $19.
Call ahead of time to ensure that the prices haven't changed. Prices are typically different for non-residents, children 16 to 17 years of age and senior citizens. In the state of California, people 70 or older, disabled veterans and former POWs are required to have a license, but can obtain one for free. The same rules apply to residents of state and county institutions, as well as those who are physically disabled.
