Etymology: Percina: Latin, diminutive of perch = perch (Ref. 45335); caprodes: Percina=a small perch; caprodes, Greek for resembling a pig (referring to the snout) (Ref. 79012). More on author: Rafinesque.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Temperate; 60°N - 30°N
North America: St. Lawrence-Great Lakes, Hudson Bay and Mississippi River basins from Quebec to Saskatchewan in Canada south to Gulf of Mexico; and Atlantic and Gulf Slope drainages in the USA.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 5723); common length : 12.5 cm TL male/unsexed; (Ref. 12193); max. reported age: 3.00 years (Ref. 12193)
Most common over gravel and sand in medium-sized rivers but can be found almost anywhere from small, fast-flowing rock-bottomed streams to vegetated lakes (Ref. 5723, 10294). Adults feed on larvae of midges, mayflies, caddisflies (especially hydropsychids), riffle beetles, stoneflies, limpets, and fish eggs (Ref. 10294). Eggs are found buried in the substrate (Ref. 7043).
Spawns in running water on sand or fine roots over sand (Ref. 7471). Eggs are found buried in the substrate (Ref. 7043).
