Largescale Stoneroller
Campostoma oligolepis
Largescale Stoneroller is a small North American minnow that grazes algae and organic films in clear, shallow streams. It is not a common sport fish; anglers usually catch it incidentally while fishing creeks and small rivers.
Titik pengenalan
- Large, obvious dark-edged scales that give a rough-looking body
- Small subterminal scraping mouth with thick, hornlike lips
- Olive to brown back with a paler belly and a streamlined minnow shape
Habitat
Clear to slightly turbid warmwater streams and small rivers with riffles, runs, and cobble or gravel bottoms where algae grows on stones; also occurs in pools and margins of moderate-current channels.
Nota umpan
Not usually targeted. Small pieces of worm, maggots, or tiny dough/crumb baits will take them; ultra-small jigs or bits of soft plastic can work, but they more often bite while sampling algae-coated cover than chasing lures.
Tingkah laku
A benthic herbivore that scrapes algae and diatoms from rocks with a specialized mouth. It schools in shallow current and is most active where rock surfaces are sunlit and productive; it spawns in spring over gravelly riffles.
Berhati-hati
none notable
Nota memancing
Use light line and tiny hooks in shallow riffles, behind rocks, and along current seams. Present baits naturally near the bottom with little weight; they often peck rather than strike hard. Handle gently and release promptly if caught incidentally.
