Have you observed Red Spot Disease?

OzFish would like to know about it.

In the recent devastation of drought and widespread bushfire, with the subsequent rainfall, some of Australia’s key waterways have been destroyed.

OzFish volunteer Chapters can help gather information to understand the impact on their local waterway and fish.

Part of this is recognising when and where Red Spot Disease is occurring.

OzFish is encouraging fishers to report basic information using our online form and to submit this with any photos you might have.

Record sighting of Red Spot to OzFish

REPORT RED SPOT

What to look for?

Fishers should be on the lookout for any:

  • red sores,
  • red ulcers or
  • red lesions on their fish.

These are caused by a fungus and can develop into secondary infections. The sores begin as small red spots on a single fish scale and can grow until scales are lost and muscle tissue becomes exposed, presenting as a severely ulcerated fish that should not be eaten.

More information can be found on the DPI’s website.

24 MAY 2021 | Recreational Fishers Taking The Lead On Improving Richmond River’s Water Quality

After 50 years of problems and three years of research, plans to improve the Tuckean Swamp, the single largest contributor of poor water quality in the Richmond River, are about to be released. The latest research has recommended limiting drainage of the floodplain’s lowest lying areas, those less than 1m above sea level, that are regularly inundated. These low-lying areas are known to be responsible for the majority of low oxygen (blackwater) and acidic water conditions. This poor water has effectively nullified the fish and prawn habitat nursery in the area. The next steps, will be understanding the costs and benefits of any actions and this work will commence next month. OzFish Unlimited, Australia’s national recreational fishing conservation charity are spearheading the project, working with Councils, State Government agencies, indigenous groups and The Nature Conservancy to pave the way to secure the improvements.
