Taiwan Torrent Carp
Acrossocheilus paradoxus
Taiwan Torrent Carp (Acrossocheilus paradoxus) is a stream-dwelling cyprinid endemic to Taiwan. It lives in clear, fast-flowing mountain rivers where it grazes algae and small invertebrates from rocks.

Identification points
- Deep, laterally compressed cyprinid body with a blunt head
- Subterminal mouth suited for grazing on rocks
- Dark body with lighter longitudinal markings/reticulation typical of Acrossocheilus
Habitat
Cool, clear, fast-moving mountain streams and upper river reaches in Taiwan, especially riffles, runs, and shallow pools with cobble, boulders, and strong current.
Bait notes
Small worms, insect larvae, and tiny dough or bread baits can take fish where allowed; small nymphs, bead-head wet flies, and tiny spinners are practical artificials.
Behavior
Primarily a benthic grazer that scrapes algae and biofilm from rocks and also picks small aquatic invertebrates; usually holds close to current breaks and rock edges.
Caution
Freshwater species with no notable species-specific consumption hazard known; check local regulations because stream fishes in Taiwan may have site-specific harvest restrictions.
Fishing notes
Fish light line and small hooks or micro-lures, drifting naturally along riffles, seams, and behind rocks. Present baits tight to the bottom and keep retrieves slow in current.
