Walpole Fish — A Field Guide to the Fish of Walpole-Nornalup, WA
Walpole-Nornalup · Western Australia

Where the Forest Meets the Sea.

A field guide to the fish of Walpole — from the tannin-stained rivers and shallow inlets to the surf gutters and offshore reefs of the Southern Ocean. With a few south-west endemics found nowhere else on Earth.

A mosaic of waters.

The Walpole-Nornalup Inlet system is one of the most diverse aquatic environments on the south coast — a shallow estuary, fed by two tannin-stained rivers, that opens narrowly to the Southern Ocean. The mixing of fresh, brackish and marine water sustains a remarkable range of fish.

The region is also home to several south-west endemic freshwater fish, including the salamanderfish — a tiny "living fossil" found nowhere else but a small radius around Walpole. Below, the fish you're likely to encounter, grouped by where they live.
