Luderick

Girella tricuspidata

Luderick (Girella tricuspidata) is a coastal herbivorous fish common around southern and eastern Australian estuaries, rocky shores, and breakwalls. It grazes on algae and sea lettuce, and is a popular light-tackle target where weed beds and current seams hold fish.

Identification points

  • Deep, oval body with a small mouth suited to grazing
  • Dark greenish to brown back with silvery sides
  • Three distinct tricuspid teeth on each side of the jaws give the species name

Habitat

Rocky reefs, jetties, estuary mouths, breakwalls, wharf pylons, and weed-covered shallow bays; often around kelp, green weed, and current lines in sheltered coastal water.

Bait notes

Best baits are green weed, cabbage weed, sea lettuce, or nori tied on a small hook. Small pieces of peeled prawn, bread, and weed flies can work when fish are feeding cautiously.

Behavior

Mostly feeds by grazing on algae and marine weeds, especially on tide movement and around submerged structure. It schools in estuaries and along open coast reefs, and can be wary and line-shy.

Caution

Edible and generally safe to eat, though fish taken from polluted estuaries may reflect local contamination advisories. Check local regulations and any water-quality warnings before keeping fish.

Fishing notes

Use light line, small hooks, minimal sinker weight, and present baits naturally under float or just off the bottom. Target tide changes, wash zones, and shaded structure; berley with chopped weed if allowed.
