The Fisheries Research and Development Corporation’s (FRDC) annual Status of Australian Fish Stocks 2018 (SAFS) report is out this month. The report covers 120 species made up of 406 stocks across finfish, crustaceans, molluscs and sharks and rays – an increase of 37 species on the previous report released in 2016.

Key facts from the report:

  • Majority of Australia’s assessed fish stocks are sustainable.
  • Largest assessment of fish stocks ever undertaken in Australia.
  • 120 species and 406 stocks assessed.
  • Southern Bluefin Tuna now rated as recovering.
  • Pacific stock of Bigeye Tuna goes from depleted to sustainable.

Overall, almost 80% of the 406 stocks were able to be assessed.  Of those assessed, almost 85% were sustainable or recovering.

The report brings together the best available information to determine the status of Australia’s key wild fish stocks against an agreed national reporting framework. The framework provides transparency and consistency in stock status reporting across jurisdictions.

To read the full reports, visit or access through a new smartphone app SAFS – Sustainable Fish Stocks available through both the app store and Google Play.

Aquaculture fish farming may be more important now than ever.

We need to start taking the pressure off our oceans and start aquaculture fish farming more and varied fish species to help feed the masses, and let our oceans rebuild their stocks.

Working with companies such as Pure Aquatics, you can learn, design and set up a professional aquaculture farm from the get go. Couple that with Toyesi’s Farm Fresh Trident reverse cycle heat pumps/chillers you can now control ideal water temperatures.

The benefits of this is to provide ideal growth conditions from hatchery through to grow out. This will increase the speed to market capability of your aquaculture venture, but also allow you to control seasonal temperature ranges outside normal environmental conditions, giving you extra breading cycles throughout the year for brood-stock.
