Species Information

This is a small, plain fish, with a snout that slightly overhangs the lower jaw: the dorsal fin originates in front of the pelvic fin, the mouth is small and the scales are large (37-40 along the lateral line). It lacks maxillary barbels. For further information, refer to McPhail (2008).

Identification and Subspecies Information

The British Columbia Conservation Data Center recognizes two blue-listed populations of this species:

1) Hybognathus hankinsoni - Pacific group
2) Hybognathus hankinsoni - western Arctic group

Biology

Species Biology

Adults occur in cool pools of sluggish, clear creeks and small rivers, usually over sand or gravel; more abundant in cool acid waters of silt-bottomed bog ponds (Ref. 1998). Probably feed on phytoplankton and other algae, zooplankton, and aquatic insects (Ref. 1998). Oviparous, open substratum spawners (Ref. 205, 52559). Probably spawn in May or June over silty bottoms of calm waters (Ref. 1998). Predators may include brook trout, kingfishers, and mergansers (Ref. 1998).

Distribution

BC Distribution and Notes

The biology of this little fish is a mystery. It is especially abundant in the lower Fraser Valley and headwater ponds and small lakes in the Prince George area. In between it is exceedingly rare. In the lower Fraser Valley it appears to migrate to and from the main river; however, its movements are largely uncharted. All we know is that, seasonally, it turns up in large numbers at some sites and then disappears. The populations in the Esker Provincial Park appear to be extinct. Probably victims of an exotic species (brook trout) introduced to create a recreational fishery.

Global Distribution

North America: upper St. Lawrence River and Lake Champlain drainages in Quebec, Canada and New York, USA; across Great Lakes, Hudson Bay and Missouri-upper Mississippi River basins of southern Canada and northern USA south to Kansas; Peace River (Ref. 1998) and Fraser River system (Pacific Slope) in Alberta and British Columbia, Canada.
