Citizen science group conducts survey for aquatic life on the Upper Karuah River.

The Upper Karuah River located west of Stroud, NSW, is the furthest reach of the proposed Worimi World Heritage Estuary. This stream provides an important fish and wildlife migration corridor from Barrington Tops National Park, down the Karuah River mainstem, through Port Stephens, and out to the open sea.

On February 18th and 19th, 2018, ten members of the Australia/New Guinea Fish Association (ANGFA), traveled to the headwaters of the Karuah River to conduct an aquatic “bio-blitz.” The amount of fish and aquatic life biodiversity that these experts discovered was outstanding. Most importantly, they found no introduced or pest fish (such as Gambusia) in these pristine headwaters.
