SARA Status: Threatened

Several horizontal sections on this infographic show the following:

An illustration of the Plains Minnow (Hybognathus placitus), © Joseph R. Tomelleri, with the following aspects labelled:

• small eyes positioned just above the midline of the head
• short, triangular head with a blunt snout and a subterminal mouth
• silvery minnow
• adults range between 50-90 mm in length, maximum 125-130 mm

The next section lists threats, including:

• contaminants
• habitat degradation
• invasive/introduced species/disease
• water level management

A further section notes that Canadian populations are highly restricted and have been found only in southwestern Saskatchewan, the northern limits of its distribution. This very limited area includes Rock Creek and Morgan Creek.

To the right of the infographic, a map of Saskatchewan shows, by an overlaying rectangle, where the related population is found. Another map on the left of the infographic shows a magnified view of where the population is found by use of splotch markings, with Saskatchewan and Montana (U.S.A.) labelled.

A final section on the infographic notes that activities in or near water can harm aquatic species, and lists what you can do:

• maintain unimpeded fish passage
• prevent contaminants from entering water
• do not clear aquatic vegetation
• report any invasive species sightings to DFO
• protect sensitive habitat; contact DFO before doing any in-water work
