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.

Gull Lake is normally stocked annually with Walleye fry at the rate of 1,000 per littoral acre (2,825,000 fry). Fingerlings are stocked on a contingency basis if fall electrofishing results are less than 30 young-of-the-year (YOY) Walleye per hour for two consecutive years; fingerlings were last stocked in the fall of 2020 with the balance of that stocking completed in the spring of 2021. In 2024 the fry stocking rate was cut in half and only 1,412,500 fry were stocked to see if a reduced stocking rate could still produce a strong year class. The reduced stocking rate produced the second highest catch rate ever of YOY Walleye (196.5 per hour) since annual fall electrofishing began in 1994. In 2025, Walleye fry were stocked at the same half rate as they were in 2024. Night electrofishing was conducted on September 23rd, 2025, to monitor the abundance of YOY Walleyes. Total sample time was 2 hours, which resulted in a YOY Walleye catch rate of 107 per hour. This was the second highest catch rate in 14 years, with only 2024 having higher catch rates. YOY Walleye ranged in size from 4.8 to 6.9 inches, with a mean length of 5.7 inches. Previous catch rates ranged from zero to 271.9 per hour. Age 1 and older Walleyes were captured at the rate of 52 per hour. These fish ranged in size from 7.9 to 20.9 inches.
