COSEWIC assessment and status report on the northern sunfish, Lepomis peltastes, Saskatchewan - Nelson River populations, Great Lakes - Upper St. Lawrence populations, in Canada . : CW69-14/732-2016E-PDF
"This is a small-bodied member of the sunfish family that inhabits shallow vegetated areas of warm lakes, ponds, and slowflowing rivers. Its spatial distribution is relatively small and likely patchy. It is suspected that the index of area of occupancy and abundance of the species has declined. Threats are variable across its range with some areas of declining habitat quality and other areas with improving habitat quality. Overall, the threats of siltation, contaminants, and invasive species were assessed as high. The species is likely to become Threatened unless these threats are effectively ameliorated"--Reason for designation (Ontario, Quebec), p. iii.
