Western Blacknose Dace
Rhinichthys obtusus
Western Blacknose Dace (Rhinichthys obtusus) is a small North American cyprinid found in clear, cool streams. It lives near the bottom in riffles and runs, where it feeds on tiny aquatic and terrestrial invertebrates.
Identification points
- Distinct dark snout stripe or blackish nose patch
- Slender, silvery body with a small terminal mouth
- Dorsal side dusky olive to brown, plain fins without bold markings
Habitat
Clear, cool headwaters and small to medium streams with gravel, cobble, and sand bottoms; often in riffles, runs, and along current seams near cover.
Bait notes
Rarely a targeted game fish. Tiny pieces of worm, maggots, or bread under a light float can take it; micro jigs or small bead-head nymphs also work for observation or bait collection.
Behavior
A bottom-oriented minnow that forages in daylight by picking insect larvae, small crustaceans, and drifting bits from the substrate; often stays in tight schools and hugs current breaks.
Caution
None notable; it is a small baitfish/minnow with no known species-specific human safety concerns.
Fishing notes
Use ultra-light tackle, a #18–#24 hook, and minimal split shot or a small float. Drift baits close to the bottom in riffles and seams; avoid heavy line and noisy presentations.
