More than 90 per cent of Australia’s fisheries are at risk of going extinct, and the industry is in crisis, says a report.
It says Australia’s population is expected to double by 2050, and that there will be more than 3 million jobs lost as a result.
A report from the University of Queensland and the Australia Institute says the loss of fisheries jobs is linked to pollution, habitat loss, climate change and globalisation.
The report is published today by the University’s Institute for Fisheries Studies.
“We know that we’re going to lose about 90 per [per cent] of the world’s fisheries,” says Dr Paul Cripps, lead author of the report.
“So we know that it’s very difficult to sustain a healthy population of fish.
We know that there’s an enormous amount of pressure on the fishery.”
He says the report is part of a global push to find ways to sustain the global fisheries.
“It’s not about trying to kill fish.
It’s about trying do something about it, and then try to do something with it,” he says.
The study uses a mathematical model of the global fish economy.
It finds the fishers are already suffering from an unsustainable, loss of catch, as a consequence of global warming.
“The fishery’s got to be a huge, vast, massive thing to sustain, and if you don’t have a huge fishery, you’re going kill fish,” he said.
He says most of the population in the world today is fishing for fish.
“And that’s where we’ve lost the most species, and we’ve also lost a lot of species that would otherwise be able to go on to reproduce, because they’ve become too dependent on the system to reproduce.”
“It is not that we’ve got a lack of species in the fisheries, it is that the systems are not working.”
Crippson says there are more than 100 species of fish currently being caught around the world.
“But most of them are not being exploited,” he added.
He said there were many reasons for that, including poor management of fish stocks, overfishing, and a lack “of understanding of the impact of these fisheries on the ocean ecosystem”.
In the past, there has been a shift in focus towards environmental issues, he said, with “the focus shifted away from the economic side”.
“We’ve also seen a shift from the concern about the economy to the ecological side,” he explained.
But the report points out that in some countries, particularly in Asia, there are plans to tackle pollution and habitat loss. “
There are a lot more people that are getting sick, there’s a lot less habitat to move around in.”

It recommends more emphasis on sustainable fisheries management.
The paper concludes: “While there are many different ways to address the sustainability of fisheries, they all have some common characteristics, such as the need to preserve marine ecosystems, promote biodiversity, and support fisheries for future generations.”
“The fisheries are a part of Australia,” said Professor Paul Sibley from the Australian National University.
He said the report showed Australia could still do more to conserve the world fish stocks. “
If we don’t get this right, then there will not be enough fish left in the ocean to feed people, or to feed the ocean for future people.”
He said the report showed Australia could still do more to conserve the world fish stocks.
“Australia has an incredible opportunity to save these fish stocks,” he told ABC Radio.
We’re not investing enough to get these stocks back in balance.””
Unfortunately we are failing to manage them properly.
