Other Statuses

Committee on the Status of Endangered Wildlife in Canada (COSEWIC): Not at Risk (01Apr1989)
Comments on COSEWIC: Reason for Designation: Although the species may be declining in Lake Erie, and possibly extirpated from Lake Ontario, it is common throughout the rest of its widespread range in Canada.

Status History: Designated Not at Risk in April 1989. More recently (2015) considered a medium priority candidate for re-assessment

IUCN Red List Category: LC - Least concern

NatureServe Global Conservation Status Factors

Range Extent: >2,500,000 square km (greater than 1,000,000 square miles)
Range Extent Comments: Range includes the Great Lakes-St. Lawrence and Arctic basins from southern Quebec to the Mackenzie River drainage, Northwest Territories, Yukon, and northeastern British Columbia, south to Great Lakes and northern Montana; Milk River system, Missouri River drainage, southern Alberta (Page and Burr 2011).

Number of Occurrences: 81 to >300
Number of Occurrences Comments: This species is represented by a large number of occurrences (subpopulations).

Population Size: 100,000 to >1,000,000 individuals
Population Size Comments: Total adult population size is unknown but quite large. This species is common (Page and Burr 2011).

Overall Threat Impact Comments: No major threats are known in the vast majority of the range. Causes of the decline at the southern extreme of the range in the lower Great Lakes are unknown but might include pesticide and herbicide pollution, predation by or competition with alewife, habitat degradation due to siltation, chronic trace contaminant exposure, or shifts in species composition in the deepwater communities (Houston 1990).

Short-term Trend: Relatively Stable (<=10% change)
Short-term Trend Comments: Trend over the past 10 years or three generations is uncertain but likely relatively stable over the vast majority of the range. See Houston (1990) for information on status in Canada.

Long-term Trend:  
Long-term Trend Comments: This sculpin has disappeared from much of the southern extreme of the range in the lower Great Lakes region.

Reproduction Comments: Apparently spawns late summer or early fall (Becker 1983).
Habitat Type: Freshwater
Non-Migrant: N
Locally Migrant: N
Long Distance Migrant: N
Riverine Habitat(s): CREEK, MEDIUM RIVER
Lacustrine Habitat(s): Deep water, Shallow water
Special Habitat Factors: Benthic
Habitat Comments: Varied habitat includes swift creeks and small to medium rivers, and inshore shallows and deeper waters of lakes, to depths of 137 meters (Page and Burr 2011). Usually occurs at depths of 20-50 meters in Great Lakes, 15-20 meters and 4-8 C (rarely to 18 C) in eastern Ontario and western Quebec. Occasionally in brackish water.
Adult Food Habits: Invertivore
Immature Food Habits: Invertivore
Food Comments: One study found diet dominated by crustaceans (especially amphipods, Mysis, and copepods); also included insects, fish eggs, and other material (Becker 1983).
Length: 11 centimeters

Group Name: Freshwater Sculpins

Use Class: Not applicable
Minimum Criteria for an Occurrence: Occurrences are based on evidence of historical presence, or current and likely recurring presence, at a given location. Such evidence minimally includes collection or reliable observation and documentation of one or more individuals (including eggs and larvae) in appropriate habitat.
Separation Barriers: Dam lacking a suitable fishway; high waterfall; upland habitat.
Separation Distance for Unsuitable Habitat: 10 km
Separation Distance for Suitable Habitat: 10 km
Separation Justification: Data on dispersal and other movements generally are not available. Separation distances (in aquatic kilometers) are arbitrary. Separation distance reflects the likely low probability that two occupied locations separated by less than several kilometers of aquatic habitat would represent truly independent populations over the long term.

Because of the difficulty in defining suitable versus unsuitable habitat, especially with respect to dispersal, and to simplify the delineation of occurrences, a single separation distance is used regardless of habitat quality.
