Stocking history

Year	Species	Size	Number	Pounds
2024	Muskellunge	fingerlings	764	267.7
2022	Muskellunge	fingerlings	756	175.3
2019	Muskellunge	fingerlings	750	174.4
2018	Muskellunge	fingerlings	756	77.1
2016	Muskellunge	fingerlings	765	102.0

Field note · Minnesota stocks by year, not by truck day: walleye fry go in within weeks of ice-out, fingerlings and yearlings mostly in fall, and stream trout in spring and fall. A row here means the fish went in during that year; DNR adds the year's rows after the fact, so the current year can look empty until winter.

DNR fish survey, 2025

Species	Gear	Catch per net	Total catch	Avg lb
Muskellunge	Open-water angling	1.00	14	23.79
Muskellunge	Musky trap nets	0.32	59	18.24

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.

The 2025 target survey consisted of spring trap netting to examine Muskellunge for passive integrated transponder so a population estimate can be made Muskellunge.
