Angler AIS Prevention Pass

The Angler AIS Prevention Pass (AISPP) is required for all individuals who fish in Montana. This program was initiated by the 2017 Montana Legislature to help fund the fight against aquatic invasive species in Montana.

The Angler AISPP is $2 for residents and $7.50 for nonresidents and is required with your purchase of a fishing license. There is no fee for youth 15 and younger. Individuals who don’t fish but would like to help in the fight against aquatic invasive species may also purchase the AISPP.

AISPPs may be purchased at the Online Licenses Service along with your fishing license, or visit a License Provider location.
