Fish death reported on the Anglesea River.  EstuaryWatchers visited the estuary and reported about 15 dead fish from the mouth of the estuary to 100m upstream of the Great Ocean Road Bridge. Most of the dead fish were within 100m of the Great Ocean Road Bridge. The largest fish was around 400mm.

After talking to the tourism operaters and community members that regularly frequent the river it seems the fish death occurred 1-2 weeks before December 11.  Many of the smaller fish that died had either decomposed or been eaten by birds.
