Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
North Long Lake is stocked annually with 3.9 million Walleye fry. Fingerling stocking is done on a contingency basis as needed or as surplus when fish are available and was last done in 2024. Night electrofishing was conducted on September 11th, 2025, to monitor the abundance of young-of-the-year (YOY) Walleyes. Total sample time was 2 hours and 10 minutes, which resulted in a YOY Walleye catch rate of 1.4 per hour. This was the first time since 2018 that YOY Walleye were sampled. They ranged in size from 5.4 to 6.4 inches, with a mean length of 6.0 inches. Previous catches ranged from 0 to 53.3 per hour. Age 1 and older Walleyes were captured at a rate of 6.5 per hour. They ranged in length from 7.5 to 25.8 inches and had a mean length of 12.4 inches.
