Fortunately Alaska's fishing license regulations are clear and easy to comply with.
The main factor that affects the price of your non-resident sport fishing license in Alaska is the number of consecutive days that you plan to go fishing:
1 day = $25
3 days = $45
7 days = $70
14 days = $105
Calendar year = $145
You can purchase your license once you arrive in Alaska, or you can buy it online in advance here: https://www.adfg.alaska.gov/Store/
