Fishing for conservation

On an unnamed tributary, Fish & Game field officer Allen Stancliff and ecologist Bart Jansma survey Waiwhakaiho tributary with an electrofishing rig.

The pulse of the current stuns the fish momentarily, allowing Allen to scoop them up with a sieve.

It’s a reliable method for monitoring fish life in the tributary, abundance data that will contribute to scientists’ understanding of the health of the waterway and the welfare of the fragile ecology within it. They find a juvenile trout, and a handful of native kōaro which migrated upstream as whitebait.
