Mass Fish Kill - New South Wales, Australia
Hundreds of thousands of fish have asked up alongs beaches and river banks along the New South Wales north coast as a result of the floods that have recently hit the area.
The reason behind the widespread fish kills across the catchment — already one of the most polluted in the country — is the lack of oxygen in the water. After a flood, accumulated detritus in the wetlands decomposes and chews up all the oxygen in the water.
The area has a flood plain that drains very quickly which leaves the fish unprepared for the massive oxygen debt in the water. All sorts of fish have been affected: juvenile fish, big fish, all the major species. Sea mullet, bream, flathead, whiting, and then all the small fish, even toadfish.
