Identification
- Muskies show dark spots or bars on a light background, the reverse of northern pike, and are silver, light green or light brown.[2]
What the source says
“Native muskies have darker markings (spots or bars) on a light background. That's the opposite of northern pike, which have light markings on a dark body. Muskies are silver, light green, or light brown.”
- Both the gill cover and the cheek are scaled only on their upper halves, and there are 6 to 9 pores along each side of the lower jaw.[1]
What the source says
“This species differs from other members of the pike family in having both the gill cover and cheek scaled only on their upper halves, and in having a row of 6 to 9 pores along each side of the lower jaw.”
- Minnesota DNR says the tiger muskie, a sterile pike-muskie hybrid, is told apart by its rounded tail fins; like a muskie, it has dark markings on a light background.[2]
What the source says
“Rounded tail fins identify the tiger muskie, a sterile hybrid of the northern pike and the muskie that is stocked in several heavily fished lakes in the Twin Cities. Like native muskie, this fish has dark markings on a light background with the key difference its tail fins.”
Habitat and range
- The native range covers the St. Lawrence-Great Lakes and Mississippi basins from Quebec to southeastern Manitoba, south in the Appalachians to Georgia and west to Iowa.[3]
What the source says
“Native Range: St. Lawrence River-Great Lakes and Mississippi River basins, from Quebec to southeastern Manitoba; south in the Appalachians to Georgia and in the west to Iowa (Page and Burr 1991).”
- USGS describes the tiger muskellunge as both a natural and a hatchery hybrid; it occurs naturally where pike and muskie ranges overlap in the northeastern and western Great Lakes regions.[4]
What the source says
“Native Range: A natural and artificial hybrid. Hybridization occurs in nature where the two species' ranges overlap, in the northeastern and western Great Lakes regions (Lee et al. 1980 et seq.).”
- Michigan DNR says muskies may move to slightly deeper, cooler water in peak summer heat, and can tolerate water up to 90 F if necessary.[5]
What the source says
“During summer's peak heat a muskie may move into slightly deeper, cooler waters but will still choose the protection of a drop-off or some underwater structure. If necessary, the muskie can withstand water temperatures up to 90 degrees F.”
Life history
- Muskies spawn in early spring shortly after ice-out, after pike, broadcasting eggs among plants in 15 to 20 inches of water at about 55 F.[5]
What the source says
“The muskie spawns in early spring shortly after the ice has melted, but after the spawning of the northern pike. Eggs are broadcast among vegetation, in water only 15 to 20 inches deep and with a temperature of about 55 degrees F.”
Status, protections and rules
Legal status and rules as the agency stated them on the date read. Rules change: check the current regulations for the water.
- Minnesota DNR rule: anglers cannot keep a muskie unless it is at least 54 inches long.[2]
What the source says
“Anglers can't keep a muskie unless it is at least 54 inches long.”
- Michigan no longer raises tiger muskellunge in state hatcheries; wild-produced tigers are rarely caught.[5]
What the source says
“Tiger muskellunge, a hybrid between northern pike and muskellunge, were once stocked in Michigan, but no longer are raised in state fish hatcheries. Naturally-produced tiger muskellunge are rarely caught, though they are more prevalent in lakes with high abundance of northern pike.”
Fishing for it: what the agencies say
What agencies and extension services say about catching it, with the source for each line.
- Minnesota DNR says muskies are hard to catch because there are few of them in a lake, not because they are crafty.[2]
What the source says
“Muskies may indeed be elusive. But it is their low numbers in a lake – not craftiness – that makes them hard to catch.”
- Muskies often follow lures to the boat and may strike with only a foot of line out.[1]
What the source says
“Another interesting habit of muskellunge is their tendency to follow lures to the boat, oftentimes hitting the lure with only a foot of line out.”
General advice (ours, not an agency's)
- Ask a local shop which flies are working on that lake or river this month.
- Check the state's size, possession and transport rules before you keep or move a fish.
Where to fish for muskellunge
None of our water pages has an agency species list that names muskellunge yet. Agencies publish species lists for only some waters; we never add a species from anywhere else.
