Rosy Bitterling
Rhodeus ocellatus
The rosy bitterling is a small East Asian cyprinid known for the male’s rosy breeding colors and a dark spot at the base of the dorsal fin. It is closely tied to freshwater mussels for spawning and is best known as an aquarium and conservation species rather than a sport fish.

识别要点
- Small, deep-bodied bitterling with silvery-gold flanks and a rosy blush in breeding males
- Distinct dark ocellus at the front base of the dorsal fin
- Short dorsal fin and small mouth; females show a slender ovipositor in breeding season
栖息地
Slow-flowing or still freshwater such as ponds, canals, ditches, rice paddies, and vegetated lowland streams, especially where unionid mussels are present for spawning.
饵料备注
Not a common angling target. If encountered, tiny bread crumbs, small worms, bloodworms, daphnia-sized baits, or micro jigs/maggots are more appropriate than large lures.
行为
Feeds mainly on small invertebrates, algae, and plant material. In breeding season males become colorful and territorial, and females lay eggs in live mussels using a long ovipositor.
注意事项
Do not disturb or remove freshwater mussels during spawning; the species depends on them and may be protected or restricted in parts of its introduced range. Avoid releasing aquarium fish into the wild.
钓法备注
Best approached with ultra-light tackle, small hooks, and fine line in calm shallow water near weeds or mussel beds. Most captures are incidental; catch-and-release is preferable where native or protected.
