Muskellunge in North America

Distribution and Management of Muskellunge in North America: An Overview


This report has been prepared to document current muskellunge (Esox masquinongy) distribution in North America as well as summarize and compare management approaches used in various jurisdictions.

This is not the first survey, regarding muskellunge management activities in North America, to be conducted. A similar agency questionnaire was carried out by the North Dakota Game and Fish Department in 1985 (Ragan et al. 1986).

The Esocid Technical Committee, Northcentral Division, American Fisheries Society, compiled information on esocid research and management in 1992 (ETC 1992), esocid angling regulations in 1995 (ETC 1997a), and esocid stocking in 1996 (ETC 1997b). I am also aware of a mail survey conducted in 1981 (Miller 1983) but was unable to obtain results from that undertaking.

Information contained in this report was derived from a number of sources including a survey of state/provincial staff (conducted during the fall of 2010), an internet search of muskellunge regulations in various jurisdictions, and a review of published literature.

Completed surveys were received from 59 individuals (see Appendix 1) representing 56 different North American jurisdictions.

In most instances, a single response was received from an individual jurisdiction. In other cases, several responses were received and combined to form a provincial or state response. Survey responses were not received from Alabama, Delaware, Idaho, Massachusetts, New Jersey, and South Carolina.

Much of the outstanding information (e.g., number of muskellunge waters, number of fish stocked, etc.) for non-responding jurisdictions was obtained from agency websites.

Muskellunge Distribution in North America Native Range

The muskellunge (Esox masquinongy) is only found in North America. Muskellunge are indigenous to the Great Lakes region and upper Mississippi drainages of eastern North America (Hubbs and Lagler 1958, MacKay 1963, Berra 2001).

Muskellunge are found in all five of the Great Lakes (Superior, Michigan, Huron, Erie, and Ontario) and four connecting channels (St. Clair, Detroit, Niagara, and St. Lawrence rivers) (Scott and Crossman 1973).

In Michigan, muskellunge were originally present in the Great Lakes as well as several inland waters of the upper peninsula (Thomas et al. undated).

The original distribution of muskellunge in Wisconsin was believed to have been in the headwater basins of the Chippewa-Flambeau and Wisconsin River systems in the north-central portion of the state (Oehmcke et al. 1965).

There are more than one hundred muskellunge lakes, from all three drainage basins in the state of Minnesota (Wingate and Younk 2007).

Muskellunge were indigenous to the Ohio and Lake Erie drainages of Pennsylvania (Bean 1908, A. Woomer pers. comm.).

In New York state, muskellunge were found in the Allegheny drainage but have been introduced elsewhere (Smith 1985).

The native range of muskellunge in West Virginia was confined to the Ohio River drainage (Bean 1908, Miles 1978).

The presence of muskellunge in the Tennessee and Cumberland River drainages is among the southernmost in the United States (Parsons 1959). They are not a native species in the New England states (Warye 2002).

In Canada, the muskellunge’s original range was limited to the provinces of Ontario and Québec (Scott and Crossman 1973). In Québec, muskellunge were found in the Saint Lawrence River and southern Québec (north and south of the St. Lawrence River).

In Ontario, muskellunge are found in the Great Lakes as well as in southern and northwestern Ontario (OMNR 1987, Kerr 2001a). There have been some occurrences of muskellunge in the Winnipeg River in the extreme eastern part of Manitoba (Stewart and Watkinson 2004).

A total of 1,866 muskellunge waters in North America were identified during this survey (Table 1). Over 80% (1,527 waters) of these waters containing muskellunge are located in just five jurisdictions (Michigan, Minnesota, Ontario, West Virginia, and Wisconsin).

Muskellunge are absent from a number of North American jurisdictions including Alaska, Alberta, Arizona, British Columbia, California, Colorado, Connecticut, Delaware, Florida, Georgia, Hawaii, Idaho, Kansas, Louisiana, Mississippi, Montana, Nevada, Newfoundland, New Hampshire, New Mexico, Nova Scotia, Oklahoma, Prince Edward Island, Puerto Rico, Rhode Island, Saskatchewan, Utah, and Wyoming.

Although muskellunge are sometimes captured in the Manitoba waters of the Winnipeg River (downstream migrants from Lake of the Woods), there are no established muskellunge populations in the province of Manitoba (J. O’Connor pers. comm.).

Historic Declines in Abundance

Muskellunge abundance had declined in many jurisdictions by the late 1800s – early 1900s. Their decline was attributed largely to overexploitation and habitat destruction (Graff 1986).

Historical records indicate that muskellunge were indigenous to several lakes in northeastern Illinois but were extirpated by the early 1900s.

In Green Bay, Lake Michigan, muskellunge were decimated by the early portion of the 20th century. The decline was attributed to pollution, habitat destruction, and overexploitation (Anon. 2010).

Once abundant in Lake Simcoe, Ontario, muskellunge had disappeared by the 1930s. Their decline was attributed to habitat destruction, illegal harvest, and the increased abundance of northern pike (MacCrimmon and Skobe 1970).

In northwestern Minnesota, there was an abrupt decline in muskellunge catches in the late 1930s (Olson and Cunningham 1989). In Wisconsin, muskellunge declined following the growth of recreational angling after World War II.

Declines in muskellunge abundance were recorded in Ohio waters as early as 1850 (Buss 1960, Clark 1964). By 1950, muskellunge in the Ohio tributaries of Lake Erie was almost considered extirpated (Trautman 1957). Muskellunge had been extirpated from North Carolina by the 1950s (Clemmons 1977).

In Indiana, native muskellunge had all but disappeared by the 1960s (Jordan 2008). Native muskellunge were extirpated from four Kentucky streams as a result of habitat degradation from coal mining activities (Axon and Kornman 1986).

In the St. Lawrence River, the muskellunge fishery declined substantially during the late 1970s-1980s (Farrell et al. 2003).

Introductions and Range Extensions

Stocking has served to expand the distribution of muskellunge in a number of locations beyond its natural range. Forty-six percent (864 waters) of all North American muskellunge waters have resulted from introductions (Table 2).

There are records of non-native muskellunge introductions in 32 different states (Fuller 1999). These programs were intended either to re-introduce muskellunge to an area they once inhabited or to expand their range.

In some jurisdictions (e.g., Illinois, Iowa, Missouri), virtually all of the current muskellunge fisheries are the result of introductions (Esocid Technical Committee 1992).

Not all muskellunge introductions were planned. In the province of New Brunswick, muskellunge became established in the St. John River system during the 1970s as a result of downstream migration from a stocked headwater lake (Lac Frontiere) in Québec (Stocek et a. 1999).

This same Québec stocking also resulted in muskellunge becoming established in Maine waters of the St. John River watershed (Brautigam and Lucas 2008, J. Dembeck pers. comm.).

Muskellunge were not indigenous to South Carolina. In the early 1970s, North Carolina stocked muskellunge into Adger Lake in the Broad River system.

In 1984, the first muskellunge was captured at Lockhart, South Carolina, approximately 160 kilometers downstream of the original stocking site. Apparently, muskellunge had moved downstream over 5-6 dams during periods of high water (Creel 2004).

There are also several instances where deliberate introductions have failed to establish muskellunge populations. For example, muskellunge were introduced to Georgia waters in the 1950s but never developed a self-sustaining population (Dahlberg and Scott 1971, J. Biagi pers. comm.).

In Texas, muskellunge were introduced to nine new reservoirs in the mid-late 1970s. The introductions were intended to control forage fish and expand angling opportunities but no viable populations were established and the program was discontinued (D. Terre pers. comm.).

Similarly, in California, muskellunge (from Chautauqua Lake, New York) were stocked in Merced Lake, San Francisco County, during the 1890s in an attempt to control carp but they failed to become established (D. Lentz pers. comm.).

In Alabama, muskellunge were once stocked in the Tennessee and Tallapoosa river systems ( Muskellunge are no longer stocked in Alabama.

Finally, muskellunge were introduced into several lakes in Riding Mountain National Park and Duck Mountain Provincial Park in southwestern Manitoba but failed to establish self-sustaining populations.

Almost 73% of North America’s muskellunge waters are sustained by natural reproduction. Muskellunge populations in at least 493 waters are dependent on hatchery supplementation, however.

Few jurisdictions rely solely on natural reproduction to provide fisheries (Table 3). Exceptions include the provinces of Ontario and Québec where muskellunge fisheries are managed solely on the basis of self-sustaining stocks.

Muskellunge Management in North America

Various agencies differ in their management philosophy and in what goals and objectives they establish for muskellunge within their jurisdiction.

Muskellunge, for many, are a highly prized trophy fish (Figure 1). As a result, a common management objective for many North American jurisdictions is to provide trophy fisheries for muskellunge (Ragan et al. 1986, Table 4).

In Wisconsin, muskellunge management goals are: (i) to maintain an annual harvest of fish > 76 cm (30 inches) at a level not exceeding 27%, and (ii) to maintain a trophy muskellunge fishery (Simonson and Hewett 1999).

Minnesota identified a goal of improving opportunities for trophy muskellunge in its muskellunge management plan (Minnesota DNR 2008).

Providing trophy fisheries is often accomplished through stocking programs designed to supplement natural reproduction or provide artificial fisheries.

Pennsylvania’s muskellunge management goal is to maintain or create enhanced sport fisheries through judicious plantings of muskellunge and by implementing management approaches that increase the density of naturally produced and stocked muskellunge (Lorantus and Kristine 2005).

Conversely, managing for self-sustaining, rather than artificial trophy fisheries is a management goal in some other jurisdictions.

For example, the joint (Ontario-New York) management goal for the St. Lawrence River is to perpetuate the muskellunge as a viable, self-sustaining component of the river’s fish community as well as provide quality trophy angling opportunities (Panek 1980, Farrell et al. 2003, 2007).

Figure 1. One of the most common muskellunge management goals in North America is the provision of trophy muskellunge angling opportunities (Michael Butler photo).

Table 4. Muskellunge management objectives identified by various North American jurisdictions. Respondents could identify more than one objective.

Some management agencies have developed specific objectives of achieving muskellunge densities at a certain level while maintaining a desired rate of exploitation.

For example, Iowa has two clearly stated management objectives for muskellunge: (i) to achieve an adult density of 0.1 – 0.15 fish/acre, and (ii) to provide a catch rate of one fish for every 70 – 100 hours of angling effort (Christianson et al. 1988). Most anglers prefer larger flies and larger fly rods. Some even use a 12wt fly rod with the best budget fly reels for big fish.

Similarly, a key management objective in Missouri is to maintain a density and size structure of muskellunge populations that results in average angler catch rates of one muskellunge, at least 36 inches in length, for every 20 – 40 hours of angler effort (i.e., CUE of 0.025 – 0.050) (Boone 2007, Boone et al. 2007).

In Michigan, one of the stated objectives for muskellunge management is to maintain muskellunge densities of at least 0.3 fish/acre while maintaining exploitation rates below 5% annually.

The goals for the re-establishment of muskellunge in Green Bay, Lake Michigan, are to achieve adult densities ranging from 1–0.2 adult muskellunge/acre and a catch rate of 0.04 fish/angler hour of effort (Anonymous 2010).

The goals established in Michigan’s muskellunge management plan include the protection of habitat, maintenance of self-sustaining fisheries, provision of a diversity of trophy angling opportunities, and enhanced communications with anglers.

In several jurisdictions, muskellunge are managed as a non-native and/or invasive species.

In Maine, for instance, muskellunge are considered an exotic invasive species which could potentially threaten native fishes such as brook trout and landlocked salmon (Brautigam and Lucas 2008, Lucas 2008).

Their management goal is to limit distribution and abundance by allowing unlimited harvest during a year-round open season (Brautigam and Lucas 2008).

Similarly, the province of New Brunswick has liberal regulations (e.g., 5 fish per day catch limit, no size limit, etc.) to encourage removal and control of non-native muskellunge (C. Connell pers. comm.).

Finally, although muskellunge may be present, several jurisdictions do not have regulations or management programs for the species.

In Washington, D. C., for example, some muskellunge, migrants from further upstream, are found in the non-tidal portion of the Potomac River but there is no management program for the species in that state.

Muskellunge Stocking Programs

Stocking is a management tool that has been used extensively for muskellunge, particularly in the United States. Several jurisdictions have well-established stocking programs for muskellunge.

For example, New York commenced stocking activities in Chautauqua Lake in 1887 (Graff 1986).

Cultured muskellunge have been stocked in Wisconsin since 1899 (Nevin 1901, Oehmcke 1969, Margenau 1999).

Pennsylvania initiated a muskellunge stocking program in the 1890s which was eventually discontinued but initiated again in 1953 (Graff 1986). Muskellunge in Pennsylvania waters are currently maintained by stocking (Lorantus and Kristine 2005, A. Woomer pers. comm.).

Minnesota began the propagation and stocking of muskellunge in 1911 (Younk and Pereira 2003).

Ohio and Tennessee initiated muskellunge stocking programs in 1953 (Fetterolf 1957, Trautman 1957).

Muskellunge were first introduced to Nebraska (Lake Minatare) in 1958 (Morris et al. 1974). Since then, over 70 waters have been stocked with muskellunge but currently, only a few waters are managed for the species (Bauer 2007).

Iowa initiated a muskellunge management program in 1960 when a small number of fingerlings were introduced to Clear and West Okoboji lakes (Christianson et al. 1988).

The stocking program was expanded in the 1970s and eight lakes are now stocked to provide muskellunge angling opportunities (J. Meerbeek pers. comm.).

Muskellunge stocking in Virginia commenced in 1963 (Jenkins and Burkhead 1993). Muskellunge were introduced to Pomme de Terre Lake, Missouri, in 1966 (Pflieger 1997). Muskellunge are now present in four Missouri waterbodies and are maintained solely by stocking (ETC 1997b).

In North Carolina, muskellunge stocking commenced in 1970 in an attempt to re-establish the species (Monaghan 1985).

Indiana initiated a muskellunge stocking program in 1974 and muskellunge were first introduced to Illinois in the late 1970s (ETC 1997b).

Introductions of muskellunge in Wisconsin has served to expand its natural range to all three major drainage basins in the state (Simonson and Hewett 1999).

It has been estimated that approximately 25% of muskellunge populations in Wisconsin are the result of stocking (USGS 2009).

Stocking programs were initiated in 1989 to restore muskellunge in the Great Bay of Lake Michigan (Anon. 2010).

The first record of muskellunge being cultured in Canada was believed to be at Rice Lake, Ontario, in 1876 (Kerr 2006). From the 1920s to 1990, muskellunge stocking was conducted in over 260 Ontario waters (Kerr 2001b).

Stocking programs resulted in the establishment of muskellunge in 76 new waters. Muskellunge stocking in Ontario was discontinued when the Deer Lake fish culture station was closed in 1990.

More recently, stocking has been initiated to restore muskellunge in the Spanish River delta (Lebeau 1996) and to re-introduce muskellunge to Lake Simcoe (Buchanan and Lebeau 2000).

North American jurisdictions stocked almost one million muskellunge into 343 waters in 2010 (Table 5).

Although there is evidence that muskellunge stocked at older life stages (i.e, yearlings) survive better than younger life stages (Graff 1986, Margenau 1992, 1999, Kerr and Lasenby 2001), most stocking programs currently involve the use of fingerlings (Figure 2).

Overall, fingerlings accounted for 55% of muskellunge stocked in 2010. One notable exception is the state of Nebraska which only stocks age-1 (25-35 cm in length) muskellunge in the spring of the year (D. Bauer pers. comm.).

Illinois was the only jurisdiction that reported stocking muskellunge as fry in 2010.

Figure 2. Most muskellunge stocking programs in North America involve the use of fingerling-sized fish (MNR photo).

Six jurisdictions (Ontario, Michigan, Minnesota, New York, Vermont, and Wisconsin) indicated that they were stocking muskellunge for rehabilitative purposes in waters including Green Bay (Lake Michigan), Lake Champlain, and Lake Simcoe.

In some reservoirs, muskellunge are stocked with bio manipulation objectives of controlling coarse fish including gizzard shad, carp, redhorse, and stunted yellow perch.

Annual stocking is required to maintain muskellunge fisheries in several jurisdictions including Indiana, Kentucky, and Missouri.

In Nebraska, muskellunge are stocked on a rotational basis (i.e., every 2nd or 3rd year)(D. Bauer pers. comm.). Some jurisdictions (e.g., Georgia) indicated that they may consider muskellunge introductions in the future.

Several jurisdictions (Connecticut, Colorado, Idaho, Montana, Utah, and Washington) stock tiger muskellunge (Esox lucius x Esox masquinongy) to control coarse fish (e.g., carp, suckers, etc.) populations. They utilize only the sterile hybrid in order to prevent their establishment.

Muskellunge Regulations

Open Season

Many American jurisdictions have year-round open seasons for muskellunge.

In other areas, open and closed seasons are generally utilized to protect spawning adults and reduce the period available for exploitation.

Open season dates generally reflect seasonal differences based on geography (e.g., latitude).

In some larger jurisdictions, such as Michigan and Ontario, there is more than one standard season date to reflect various climatic regimes.

In several northern jurisdictions, muskellunge seasons are closed during the spring spawning period (Table 7). Some states and provinces also have winter closures.

While season closures can afford protection to muskellunge during their vulnerable spawning period, it is generally recognized that changes to season length have little effect on fishing effort or harvest (Hoff and Serns 1986, Simonson and Hewett 1999).

Catch and Possession Limits

Catch (bag) limits are commonly used to distribute and restrict the harvest of fish. Recognizing that muskellunge exist at relatively low densities, most jurisdictions have instituted low creel limits (e.g., one fish per day).

Catch limits appear to have remained consistently low (i.e., 1-2 fish) in most North American jurisdictions over the past 25 years.

Nineteen jurisdictions currently have a daily catch limit of one fish (Table 8). In Ontario, a daily catch limit of two fish has been in place since at least 1949 (Kerr 1998).

Provincially, the limit was reduced to one fish (two in possession) in 1988.

In some jurisdictions, such as New Brunswick, Maine, and Washington, where muskellunge are considered an exotic, invasive species, catch limits are much more liberal.

Size Limit Regulations

Size limit regulations are employed by fisheries managers for a number of reasons which include providing for maximum growth, protecting immature fish until they have had the opportunity to spawn, and restricting harvest until trophy size is reached (Wingate 1986).

In some instances, large minimum size limits are used to enhance opportunities for size-based fisheries.

Size limit regulations are generally considered to be a more effective means of regulating muskellunge harvest than catch limits and open seasons (Hoff and Serns 1986).

Minimum size limits are commonly used to manage muskellunge fisheries. One of the first muskellunge size limit regulations in North America was a minimum weight of 1.8 kg (4 lb.) instituted by the state of Wisconsin (Petrie et al. 1993).

Minnesota first implemented a minimum length limit of 76.2 cm (30 inches) in 1914 (ETC 1997a). Minimum size limit regulations for muskellunge in Ontario have been in place for well over sixty years (Kerr 1998).

The first size limit of 63.5 cm (25 inches) was placed on Tennessee muskellunge in 1954 in an effort to protect dwindling stocks (Parsons 1959).

Most North American jurisdictions have one standard minimum size limit for muskellunge (Table 9).

A different approach has been taken by Ontario and Wisconsin.

Ontario has established five benchmark values based on growth potential and management objectives (Casselman et al.1999, OMNR et al. 1999): 91.4 cm (36 inches) or 101.6 cm (40 inches) for high-density populations; 111.8 (44 inches) or 121.9 (48 inches) for enhanced size fisheries, and 137.2 cm (54 inches) for world-class fisheries.

Similarly, Wisconsin has designated five minimum size limit standards so that the appropriate regulation can be applied based on the characteristics of the waterbody and its muskellunge population.

Table 9. Muskellunge size limits in various North American jurisdictions including the Great Lakes and connecting channels (MSL – Minimum Size Limit; FL – Fork Length).

Wisconsin is currently reviewing minimum size limit regulations with the goal of increasing the statewide size limit.

Several studies have indicated a positive response to the imposition or increase in minimum size limits.

These include Lake St. Clair, Ontario (MacLennan 1996), Lake of the Woods, Ontario (Mosindy 1996), Bone Lake, Wisconsin (Cornelius and Margenau 1999), the New River, Virginia (Brenden et al. 2007), and the St. Lawrence River, New York/Ontario (Farrell et al. 2007).

Based on a 1985 survey of North American jurisdictions (Ragan et al. 1986), 76.2 cm (30 inches) was the minimum size limit standard in many areas.

Since that time, minimum size limits for muskellunge have progressively increased in northern jurisdictions (Kerr 1998, Simonson and Hewett 1999, Farrell et al. 2007, Younk and Pereira 2007, Thomas et al. undated).

The changes have been a reflection of an increase in the catch-and-release ethic, more interest in sustaining trophy fisheries, and an overall desire to protect large, productive female muskellunge.

Miscellaneous Regulations

Several other gear-related regulations were identified during this survey.

For example, the state of Vermont prohibits the use of live bait while fishing for muskellunge and restricts gear to the use of artificial lures and flies only.

New York prohibits the use of gaff hooks for landing muskellunge (ETC 1997a).

In 1985, Ragan et al. (1986) reported that spearfishing for muskellunge was allowed in four states.

The only jurisdiction which identified spearing in the 2010 survey was Michigan. Michigan currently allows spearing for muskellunge through the ice on several inland lakes from December 1 – March 15.

Record-Sized Muskellunge

Record muskellunge from various North American jurisdictions are summarized in Table.

There is currently considerable dispute over the world record muskellunge, however.

The original world record muskellunge (31.7 kg), angled from the St. Lawrence River by Art Lawton in 1957, was officially disqualified in 1992 by both the Freshwater Fishing Hall of Fame (FFHF) and the International Game Fish Association (IGFA).

That fish is still recognized by the State of New York as the state record.

In 2005, the next largest muskellunge, a 31.6 kg fish angled by Louis Spray in Chippewa Flowage, Wisconsin, in 1949, was disqualified by the IGFA.

This fish is, however, still recognized by the FFHF as the world record (FFHF 2010).

The IGFA currently recognizes the world record as a 30.6 kg muskellunge angled by Cal Johnson from Lake Court Oreilles, Wisconsin, in 1949 (IGFA 2010).

The largest muskellunge reported from Ontario was a 29.5 kg fish angled from Georgian Bay by Ken O’Brien in 1988.

    2. Different fish.
    3. World record fish recognized by IGFA.
    4. Still recognized as state record fish despite being disqualified by IGFA.

None of these fish are recognized as world records by the World Record Musky Alliance (WRMA) (Jerry Newman, pers. comm.).

The WRMA recognizes a muskellunge angled by Edward Walden in 1940 as the “honorary” record. They have established a new modern-day records program to accurately document muskellunge having a minimum weight of sixty pounds (27.2 kg).

Muskellunge Management Issues

Survey respondents were given the opportunity to identify the most pressing management issues they currently faced in their jurisdiction (Table 11).

Several individuals reported more than one management issue.

Table 11. Current muskellunge management issues identified by respondents during a 2010 survey of North American jurisdictions.

Some respondents identified more than one issue while other respondents did not identify any issues.

Habitat limitations and hatchery production capacity were issues that ranked high in both the 1985 and 2010 surveys.

Habitat issues have long been recognized as being increasingly important for muskellunge management (Nelson 1978, Dombeck 1986) (Figures 3 and 4).

Figures 3 and 4. In addition to the relative shortage or absence of suitable habitat, pollution and habitat destruction are widespread muskellunge management issues (MNR photos).

For the first time, diseases and pathogens were identified by several respondents as being a muskellunge management issue.

This is undoubtedly due to infections of muskellunge in the Great Lakes by musky pox and viral hemorrhagic septicemia (VHS) over the past decade.
