License & Permit Information

Citizens from outside Pennsylvania should consult with the appropriate state agency for permit requirements.

Pennsylvania law requires anyone 16 years of age or older collecting aquatic organisms for any reason to have a valid fishing license and follow current PA Fish and Boat Commission regulations. High school and undergraduate college students are exempt from the license requirement if their teacher/educator applies for and is issued an Educational Aquatic Field Study Permit. For more information, visit the PA Fish & Boat commission website
