This species is represented by a large number of occurrences (subpopulations).
Total adult population size is unknown but very large.
Trend over the past 10 years or three generations is uncertain but likely relatively stable.
|Habitat and Ecology:||This fish usually occurs in clear small lakes, shallow vegetated areas of larger lakes, marshes, creeks, and small to large rivers. It moves to deeper cooler water in summer. Spawning occurs in shallow flooded marshes associated with lakes, inlet streams to those lakes (or flooded terrestrial vegetation at reservoir edge), or rivers; spawning habitat is basically a flooded area with emergent vegetation (optimally over short grasses or sedges). Young remain in spawning habitat for several weeks after hatching.|
|Major Threat(s):||No major threats are known.|
|Conservation Actions:||Currently, this species is of relatively low conservation concern and does not require significant additional protection or major management, monitoring, or research action.|
