If you are 13 years or older in Tennessee, you need a license to fish in the state's waters. Certain species, such as trout require an additional license. Also, special permits are required to fish in certain areas, such as the Agency Fishing Lakes, if you are within the bracket of 16-64 years old. You can buy your license online at the Go Outdoors Tennessee website or on the department's smartphone app.
