An infrared scanner captures a silhouette of each fish and triggers a camera.

The system logs fish moving upstream & downstream.

Reduced cost

Browns and rainbows spawn in the rivers entering Eucumbene and Jindabyne dams.

Generating data

In 2025, most movements into the Eucumbene began in May.

This matches the of rules for Trout Spawning Waters.

The main trout movement periods vary from year to year.

However, the data show good overlap with the closed season.

Fish length data provide insight into population structure.

Larger fish are offered extra protection during May each year.

Understanding trout movements helps assess impacts on the fishery and protect spawning.
