A small freshwater fish of the minnow family that uses the hard ridge on its lower jaw to scrape food, especially algae, from rocks.
Genus Campostoma, family Cyprinidae: several species, including the central stoneroller (C. anomalum) of the eastern and central US, and the Mexican stoneroller (C. ornatum) of the southwestern US and northern Mexico
Example sentencesExamples
As a species, stonerollers are fairly intolerant of silt and disappear from degraded streams.
As streams become more silt laden, gravel nesting sites become lost, and species like the stoneroller decline.
Typically, the central stoneroller lives in small streams in riffle areas (shallow water where the flow is broken by the stones and gravel on the streambed).
Found in both pools and riffles over a sand-gravel substrate, stonerollers require some current.
We netted lots of sunfish, and some stonerollers and blackspotted topminnows.
