识别要点

  • Deep, laterally compressed silver body with a distinctly red or orange belly in adults
  • Silvery flank marked by black speckles and a darker shoulder area
  • Powerful jaw with visible triangular, interlocking teeth and a blunt snout

栖息地

Warm, slow to moderate freshwater systems across the Amazon, Orinoco, Paraguay-Paraná and adjacent floodplains; common in backwaters, oxbow lakes, flooded forest edges, and vegetated margins.

饵料备注

Small strips of fish flesh, whole minnows, worms, shrimp, and chunks of oily baitfish can work well. Small spoons, flashy jigs, and bite-sized soft plastics also trigger strikes.

行为

Highly opportunistic and often schooling, especially juveniles; feeds on fish, fins, insects, crustaceans, seeds, and carrion, with activity often rising in low-light periods and during floods.

注意事项

Sharp teeth can cut fingers and light leaders; handle with forceps or gloves. Keep fingers away from the mouth and gill area. Regulations vary widely because it is an aquarium and invasive-species concern outside its native range.

钓法备注

Use stout light-tackle gear, wire or heavy fluorocarbon leaders, and keep lures or baits small. Fish near structure, cover, and schooling activity; chumming with fish scraps is used locally where legal.
