Introduction

Where do fish go at times of low and high flows (floods) and how far do they travel?

Radio tracking devices were surgically inserted into trout and released into the Motupiko River. The fish were then tracked on a regular basis.Radio tagged trout were followed to see how far they moved throughout the catchment.

Research Approach

Radio tags were inserted into wild captured trout and then released. They were tracked using radio antennae on the ground and in fixed-wing aircraft.

Research Results

Some fish moved long distances while others stayed in particular reaches. The Good Friday Easter flood disrupted the study with a large number of trout killed in this event.

Detailed results of the study are available in:
