Private pond owners who have 10-year-old fish-stocking permits must renew them by Feb. 28, 2010. Montana law requires fish-stocking permits to be renewed every 10 years. Montana Fish, Wildlife & Parks administers pond fish-stocking permits and sends renewal notices to affected pond owners. Permits that are not renewed become inactive. Renewals cost $10. Those with pond-stocking permits who do not receive a renewal form in the mail should contact Nancy Podolinsky at 406-444-7319, or by email at npodolinsky@mt.gov . Completed fish-stocking permit renewal forms must be returned to the appropriate FWP regional office.
