So with the controversy over FQ Spanish mackerel stock assessment a couple of points I don’t believe have been addressed:
- how can you conduct a real stock assessment when approximately 1/3 of the 334,000 square KM GBRMP is green zone ( approximately 113,333 square KM) then on top of this you have yellow zones a large portion of the remaining area where commercial operators are only allowed 1 line ( restricted process efficiency !! ) How is this area possible allowed for with in this current stock assessment model.
- why would FQ not be willing to tell stakeholders whom conducted a peer review on this current stock assessment as per Shane Snow’s question! If they don’t release the name and date this stock assessment was peer reviewed therefore it couldn’t possibly be genuinely reviewed
- what is the real impact of the increase from 40% to 60% virgin stock biomass at the backend of the stock assessment
- how after many years of drought has the stock assessing model allowed for a recruitment pulse
This new model for stock assessments needs a lot of scrutiny/ questions asked of FQ data analysts. There’s still a massive amount of questions to ask and answer. The majority of industry that I have spoken to feels the fishery is in good shape and from the video it certainly seems like it.
When FQ claims a 17% stock biomass you can’t blame fishermen for mocking them.
The dead(ish) reef flats. This is Lodestone Reef off Townsville and it is absolutely fabulous. But a lot of coral has been lost - in the last 3000 years. Most people don’t know that the sea-level has fallen by about 1 meter in this time, so the coral that was close to the water surface back then is now exposed to the air during many low tides. Corals don’t like air exposure. In this picture the “reef-flat” is relatively less live coral compared to the coral that can be seen in the blue water at the front of the reef. Behind the reef flat the white coral sand is interspersed with patches of coral. If the sea-level rises, as is often claimed due to climate change, there will be an explosion of coral on the reef flat.
This is one of the 3000 reefs of the GBR. There is no other reef system that comes close to the scale or magnitude of the GBR or is as pristine and well protected.
BTW, if you have family and friends in the city, please recommend these posts. It is important that city folk get a good idea of how the GBR works and that it is in good condition.

Get out a magnifying glass if you would like to see Australia’s fisheries harvest rate per kilogram per square kilometre in this table.
Meanwhile Aussie fishing families that have been providing sustainable seafood for decades, centuries and generations face a constant battle against fishing closures, restrictions, marine parks and many other obstacles.
