Does a 13 year old need a fishing license?
Check state regs. Most states require one at 16.
In the UK a person over twelve years of age requires an environment agency licence to fish for coarse and game fish.
There is currently no licence requirement for sea angling in the UK.
In USA, it depends on which state you live in. Lots of states have different ages to require their license. Also, if you are planning on fishing in a different state than your residence, you will probably need to get a visitor's license. The age is normally 14 for the visitors. In the UK, you need a license at 12 years of age for freshwater fishing, sea fishing does not require any license.
