The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Esox lucius x E. masquinongy

Common name: tiger muskellunge

Synonyms and Other Names: tiger musky

Identification: See the account for Esox lucius in Page and Burr (1991); characteristics and photographs of this hybrid were given in Crossman and Buss (1965) and in Buss and Miller (1967).

Size: 16.1 kg

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.).

* HUCs are not listed for states where the observation(s) cannot be approximated to a HUC (e.g. state centroids or Canadian provinces).


Means of Introduction: Intentionally stocked for sport fishing in most locations. In some areas the hybrid occurs "naturally" after stocking northern pike in native muskellunge waters (Becker 1983). Although the male tiger muskellunge are sterile, females are often fertile and are capable of backcrossing (Becker 1983). Hartel et al. (1996) suggested individuals collected in Massachusetts were a result of stock contamination.

Status: Maintained by stocking in most cases. In some areas, such as many lakes in Wisconsin, the population is maintained by natural hybridization when northern pike are stocked in native muskellunge waters (Becker 1983). Hartel et al. (1996) report only one or two individuals collected in Massachusetts.

Impact of Introduction: This hybrid probably affects smaller fish species through predation. It also is capable of backcrossing. Male tiger muskellunge are always sterile, but females are often fertile (Becker 1983).

Remarks: Tiger muskellunge have not been stocked in Oklahoma (Pigg, personal communication) or Tennessee (T. Churchill, personal communication). Koenig et al. (2015) examined the ability of stocked Tiger Muskellunge to reduce or eradicate Brook Trout (Salvelinus fontinalis) populations in high alpine lakes in Idaho, finding >90% reduction in brook trout catch per unit effort in tiger muskellunge-stocked lakes with 0-1 inlets or outlets.
