About Koaro fishing

The koaro is a native freshwater and amphidromous fish belonging to the family Galaxiidae, featuring an elongated, cylindrical, tube-like body covered in variable golden blotches and bands. Adults typically inhabit clear, fast-flowing, and deeply shaded streams as well as alpine lakes, staying near the bottom around rocks and logs. This generalized carnivore feeds on aquatic and terrestrial invertebrates, including insect larvae and amphipods. Young fish often migrate to marine environments before returning upstream, using specialized broad fins to climb vertical wet surfaces. Though not a major target for commercial sport fishing, it is occasionally encountered by anglers exploring upland headwaters.

How to catch Koaro

Tips for catching Koaro

Anglers targeting headwater streams and lakes can find success by presenting small artificial flies, nymphs, or natural baits near deep pools and rocky cover where these fish shelter from currents. Float fishing with terrestrial insects or small worms during warmer months yields good results, particularly around dusk and into the evening when the fish become more active. Light spinning tackle equipped with tiny micro-spoons or spinners can also entice strikes in clear runs. Because these fish inhabit steep, fast-flowing upland waters often inaccessible to introduced trout, precision casting and stealth are essential to avoid spooking them in shallow margins.

How Koaro migrates — Amphidromous

Moves between fresh and salt water during its life, but not specifically to spawn. Fish the estuary and the lower river.

How Koaro migrates — Amphidromous 1. Eggs: Spawned at sea or along the coast. 2. Larvae: Drift inshore with the currents. 3. Juveniles: Move into estuaries, lagoons and fresh water to feed and grow. 4. Adults: Return to the sea to mature and spawn.
