RECREATIONAL and commercial anglers will not know where to drop anchor to get their catch with new predictions climate change will impact on fish stocks.

Scientists have found that warming oceans are impacting on the breeding patterns and habitat of marine life, effectively rearranging the marine landscape as species shift towards cooler regions.

These include species such as coral trout, snapper and yellowtail kingfish.

Some recreational and commercial species are likely to decline, while others not previously in certain areas, could provide new fishing opportunities.

Researchers led by the CSIRO and University of Queensland marine ecologists Elvira Poloczanska and Anthony Richardson, have found that warming oceans are impacting on the breeding patterns and habitat of marine life.

They have recorded more than 1700 changes, including 222 in Australia, in a study published in the Nature Climate Change journal.

In 2010 Australian National Fish Collection curator Peter Last recorded Queensland groper, tiger sharks and even fish like coral trout as far south as Tasmania.

Dr Last found that yellowtail kingfish and snapper also had headed south, while north Queensland barramundi and threadfin salmon were being caught in Moreton Bay off Brisbane and on the Gold Coast.

Other fish on the move included temperate surf species such as silver drummer, rock blackfish and rock flathead and warm-water tuna and billfishes.

Dr Poloczanska said as water warmed, these species might be able to stay in southern parts over winter.

Marine species were shifting their geographic distribution towards cooler regions and doing so much faster than land-based counterparts.

Despite the ocean having absorbed 80 per cent of the heat added to the global climate system, the ocean's thermal capacity had led to surface waters warming three times more slowly than air temperatures on land.

"The leading edge or front line of a marine species distribution is moving towards the poles at the average rate of 72km per decade, which is considerably faster than terrestrial species moving pole-ward at an average of 6km per decade," Dr Poloczanska said.

Winter and spring temperatures were warming fastest.

In addition, anthropogenic carbon dioxide uptake by the oceans was altering seawater carbonate chemistry, which could impact on some marine organisms.

Associate Professor Richardson said although the study reported global impacts, there was strong evidence of change in the Australian marine environment.

Dr Poloczanska said subtropical species of fish, molluscs and plankton were shifting south through the Tasman Sea.

Dr Last found that a downside was that Tasmanian coastal species had nowhere to migrate to and were at risk of being wiped out.

The team included 19 researchers from Australia, USA, Canada, UK, Europe and South Africa.

Press release from DAFF
The Queensland Boating and Fisheries Patrol (QBFP) and commercial fishers are meeting throughout the state to join forces to tackle the key compliance issues facing the industry.

QBFP Manager Ian Fricke said the meetings would help target the patrol's efforts in protecting Queensland's fisheries.

"So far meetings have been held in Brisbane, the Burdekin and Mooloolaba with line, net, crab and trawl fishers," said Mr Fricke.

"QBFP addresses a range of fishing issues on a day-to-day basis, but with industry's input we can prioritise where they need our assistance.

"Key issues facing commercial fishing vary between sectors and areas, but they uniformly battle public misconceptions about the sustainability of their practices.

"QBFP often receive calls from people concerned about commercial fishers operating in certain areas, but they are usually legally allowed to fish there under their licence.

"Commercial fishers use a range of practices to ensure they fish sustainably, such as bycatch reduction devices to reduce capture of non-target species, catch limits and seasonal closures for spawning."

Mr Fricke said commercial fishers also struggle with illegal practices that affect their bottom line.

"Black marketing of seafood by unlicensed individuals, and theft and interference with crab pots, undermines a commercial fisher’s ability to supply product throughout the state," he said.

"QBFP routinely undertake surveillance operations to catch black marketers and illegal fishing, but we rely on tip offs from the public.

"The community can help by doing the right thing and reporting suspected illegal fishing to the Fishwatch hotline on 1800 017 116.

"By working together, we can help safeguard our fisheries resources and continue to enjoy local seafood on our dinner plates."

Commercial fishers can contact their local QBFP office for details on when the next meeting for their fishery will be held.

Original story by , The Guardian

Angling used to be about mystery and tranquillity. Now it's about landing the biggest river monster you can battle from the depths, and it's becoming a big global business, too.

Jeremy Wade, the authentically grizzled British biology teacher turned fisher-king, who is now a big star on US TV

Jeremy Wade, the authentically grizzled British biology teacher turned fisher-king, who is now a big star on US TV

"At times," says pub landlord Kevin Gardner, "it can be like standing under a cold shower ripping up £50 notes. But when you get that bite, it's just explosive – everyone on the boat is screaming and shouting, the fish is jumping, it's mayhem. It's fantastic. You can't explain it until you've done it."

The pumped-up pleasures of catching a monster of the deep were etched in Vladimir Putin's features this week after the Russian president was photographed with a humungous pike he had apparently hooked on a fishing excursion to Siberia. Not to be outdone, his counterpart in Belarus, Alexander Lukashenko, then boasted about reeling in a 126lb catfish. It is no longer enough to spend a tranquil day questing for a 2lb perch; fishing must now be an extreme adrenalin sport, travelling to the ends of the earth to land rare or gigantic leviathans. Robson Green's Extreme Fishing programmes have enjoyed huge success on Channel 5, while fishing's latest figurehead is Jeremy Wade, an authentically grizzled British biology teacher turned fisher-king who spent decades pursuing elusive underwater prizes before finding TV stardom with Discovery'sRiver Monsters. The Animal Planet series has won the channel's best-ever audience figures in the US; Wade is now feted on US talk shows and idolised by small boys.

If Putin's 46lb pike is the high-water mark of extreme fishing, it may also be the moment the Russian president jumped the shark. His latest PR stunt was greeted with incredulity by social media mockers, who doubted the size of the pike and whether he really landed it. Recreational fishing has always been riddled with disputes over gargantuan catches, but many anglers are more profoundly troubled by the ethics and iffy image of "extreme fishing".

Captain Ahab, the whale-ship captain who so obsessively hunted down Moby Dick, was literature's first extreme fisherman, but the romance of pursuing big fish was popularised by Ernest Hemingway in The Old Man and the Sea. The novel that brought Hemingway international fame – as well as a Pulitzer and a Nobel prize – tells the epic struggle of a luckless old fisherman whose line is finally nibbled by a mighty marlin after 84 days of catching nothing.

"The line rose slowly and steadily and then the surface of the ocean bulged ahead of the boat and the fish came out," wrote Hemingway. "He came out unendingly and water poured from his sides. He was bright in the sun and his head and back were dark purple and in the sun the stripes on his sides showed wide and a light lavender. His sword was as long as a baseball bat and tapered like a rapier … "

Inspired by Hemingway and made possible by motor boats and aeroplanes, extreme fishing is now a big business. Like surfers on a pilgrimage to find mystically mammoth waves, extreme anglers journey to obscure and dangerous waters to find secretive subterranean behemoths. The less intrepid visit resorts in Thailand stocked with huge (and critically endangered) freshwater species from around the world – 400lb arapaima, 300lb Mekong catfish and 200lb freshwater stingray.

Justin Maxwell Stuart, who arranges global fly-fishing experiences, was inspired to create Where Wise Men Fish after watching angler John Wilson on TV in the 1990s. "At the end of one series he was seen disappearing down an Indian river in a little coracle attached to a 60lb fish. That was a very cool thing to do," he says. Maxwell Stuart, who typically sets up high-end saltwater fly-fishing in the Bahamas for $4,000 per person per week (alcohol included), says it is a misconception that big-game fishermen (and it is mostly men, although Maxwell Stuart gets scolded by the occasional woman angler who takes offence at his company name) have more money than sense. Many extreme fishermen are "working-class guys – butchers, carpenters – who just love fishing", he says.

Kevin Gardner agrees. His extreme angling friends are ordinary blokes. "None of us are rich, we live in modest homes. This is what we do." Gardner's 25-year love affair with marlin began when, aged 24, he pitched up in Cairns, Australia, to seek out black marlin, having sold his home to fund the trip. Saving for a trip once every two years, his Hemingway moment arrived off Ascension Island in February this year: his line tweaked with a 1,320lb blue marlin and he fought for three hours to reel it in.

"You need to be a decent angler and know when to let go and when to crank up the pressure," says Gardner of the art of extreme fishing. It also requires brute strength. Strapped to his rod, Gardner felt a great burning in his legs as he strained against the power of the marlin. Some anglers who hunt them are pulled over the side of their boat; others suffer heart attacks. In this case, however, it was the fish that died before it could be returned to the water, and so it was brought to land and photographed, its sword-like bill cut off for a trophy.

For some critics, this is as unsavoury as big game hunting on land – a cruel, macho hobby that traduces fishing's tranquil traditions. Having a big fish on your line may be exciting, says Jim Masters of the Marine Conservation Society (MCS), but that is because the animal thinks it is going to die. Like Gardner's marlin, many fish die in these epic struggles, exhausted after hours of fighting on a line or pulling a boat through the water (as Hemingway's marlin did).

Like many people, Masters became interested in conservation through his passion for fishing, and believes the sport – and its TV incarnations – can educate and inspire others to do the same. "I really like fish. I really respect them. I'm still happy to catch them, but I want to know they came from a healthy marine environment and I am not endangering their stocks in any way," he says. The MCS is particularly concerned about the welfare of big fish, and the hunting of endangered or slow-growing, deep-water species (such as the Greenland shark caught by Jeremy Wade in a memorably preposterous River Monsters episode in which he sought out the Loch Ness Monster). Masters wishes extreme fishing's television stars would discuss conservation more explicitly. "I don't want to see people wrestling with a marlin for their own satisfaction, just to make themselves look big and tough – I don't think that serves any conservation purpose – but if they can weave in stronger conservation messages, we'd welcome that."

Mark Lloyd, chief executive of the Angling Trust, welcomes the airtime given to fishing but says the extreme shows don't reflect the real wonder of fishing. "In the past, Robson Green has used techniques, such as shooting fish with a bow and arrows, that are abhorrent to most anglers, for whom the welfare of the fish is paramount," he says.

The angling author and broadcaster John Bailey – like Wade, a former teacher – has fished in 64 countries, caught enormous fish and lost even larger ones, including a Beluga sturgeon estimated to have weighed 1,800lbs. "I feel a little bit hypocritical saying the Robson Green, Jeremy Wade thing is a bit bollocks … but it is a bit bollocks," says Bailey, who knows and respects Wade. "I don't like this idea of gung-ho blokes travelling around the world ignoring their carbon footprint and smashing big fish all over the place. I don't think it's doing fishing any good."

When Bailey pursued his sturgeon it was "a six-hour ordeal for both of us," he says. "I remember thinking that did me no good, and it certainly didn't do the fish any good." Catching a fish that weighs more than a man is "much more stressful" for that fish than, say, reeling in a 5lb carp because of the disparity in body weight, reasons Bailey. "Whatever fish you catch may be going through the same process, whether it's a a 10lb carp or a two-ounce roach," argues Gardner. "If you feel that way about fish, you shouldn't be fishing."

Bailey, who prefers guiding enthusiasts to secret spots in Norfolk these days, is increasingly concerned with conserving fish in Britain. "To give the debate over to Robson Green trying to catch some man-eating turtle fish in Ethiopia is ignoring a massive situation on our own doorstep," says Bailey. "I genuinely think that the only people who care about fish are fishermen. Without us, our waters would be in a very difficult position. It's all about education, conservation and respect – and realising that fish have a huge amount of dignity and beauty."

Chris Yates is one of the most beautiful of writers on fishing, an angling legend who caught the first 50lb-plus carp in Britain and presented A Passion for Angling, which celebrates its 20th anniversary next month, and is still considered the best-ever television programme about fishing. Part of the problem with extreme fishing shows is the nature of modern television, thinks Yates. "They are tearing apart whatever the beauty of the subject is and showing one populist image," he says. His series took four-and-a-half years to film. "No one in their right mind would make a TV film about fishing. I was insane to agree to do it. Fishing doesn't translate into TV, unless you can somehow convey the sense of tranquility and mystery, as [A Passion for Angling's filmmaker] Hugh Miles managed to do. There's this mystery about why you are doing it and there's this unknown world happening below the surface of the water, and your line is connecting you to it."

Yates says the way people travel the world targeting huge fish "misses the point entirely". Then again, at some point all anglers, he suspects, succumb to an "Ahab complex", like the whaling captain who obsesses over Moby Dick. "Every fisherman dreams of getting that monster fish," he says, "even the ones who really do appreciate that you can fish yourself into a parallel universe."

The previous night, a warm, calm summer's evening, Yates stepped out of his home in Dorset and sat with his rod by a pool until gone 2am. "When the line moved, there was a little blister on the surface of the water, lit by the moon. You think, 'What is that?' and it can be completely terrifying. Even after 50 years of fishing, that makes my heart stop. That's my extreme fishing – getting into an intimacy with this unknown world and not knowing where it's going to lead, and what apparition you will behold."

Daily MercuryA SURVEY of recreational fishers in the Mackay region has revealed many hold serious concerns for fish numbers if the proposed Dudgeon Point Coal Terminal goes ahead.

Environment group Communities Protecting Our Region surveyed 264 recreational fishers during the months of May and June.

The survey found 83% thought dredging would have an impact on recreational fishing, 87% thought dredging would impact water quality and 81% thought increased coal ships would adversely affect the reef and fish.

While Dudgeon Point's environmental impact statement is yet to be released, dredging of 13-15 million cubic metres of sediment has been proposed for the project.

Mackay Recreational Fishing Alliance president Lance Murray said his main concern was the exclusion zone that would be established if Dudgeon Point went ahead. "It's a compounding situation where it forces more people into a funnel, fishing in closer proximity to one another," he said.

A spokesperson for North Queensland Bulk Ports, the proponent of the Dudgeon Point project, has shot holes through the report, saying the survey was based on people's perceptions, not fact.

The survey predicted once Dudgeon Point was operational, shipping numbers at Hay Point would increase to more than 4250 per annum.

NQBP Regional Relationship Practitioner Simon Eldridge said this was wrong. "The Port of Hay Point has handled up to 1100 ships in a year," he said.

"Under the expected moderate growth scenario for the Dudgeon Point project, shipping into Hay Point is expected to reach 1530 ships by 2020, but actual numbers will depend upon market demand.

"This is far less than the inflated number of 4250."

Original story by AAP at The Australian

A FINAL report on sick fish in Gladstone Harbour says flooding - not dredging - was the main cause of the problem.

The report says flooding, combined with large numbers of fish being washed over the Awoonga dam, stressed the ecosystem in the central Queensland city's harbour and adjacent waterways.

"This study cannot rule out the possibility that the activity of dredging and associated turbidity provided additional stress to the ecosystem, but it was not the primary stressor," says the report, released on Friday.

The report was the work of an independent panel of investigators appointed by the government to investigate concerns about sick fish in the waterway.

It said the first reports of abnormalities in fish were received months after a major flood in Gladstone from December 2010 until early 2011.

"The flood event caused a dramatic influx of large barramundi (estimated 30,000), as well as other species from Lake Awoonga into the Boyne River when the Awoonga Dam spilled over," it said.

"The dam had not spilled over since the 1990s, well before the dam wall was raised in 2002.

"Many of these fish were injured (some fatally) from the force of the impact when passing over the spillway."

It said the health of fish in Gladstone Harbour returned to a more normal situation in 2012.

"All industrial activities in Gladstone that were operating in Gladstone in 2011 have continued to operate, including dredging," the report notes.

"The only factor different in 2011 compared to previous years was the significant rainfall, the subsequent flooding and the introduction of a significant biomass of fish from Lake Awoonga."

The report said flooding had also occurred in 2012 and this year.

But other than continuing reports of barramundi showing damage as a result of being washed over the spillway, there have been no reports of any recurrence of sick fish.

"The most likely cause of the abnormalities observed during this investigation is the sudden introduction of barramundi and other fish from Lake Awoonga during December 2010 to early 2011," the report says.

"Although barramundi are naturally able to move between fresh and salt water environments, it appears that these fish were overcrowded and unable to feed normally after they were suddenly re-located from Lake Awoonga into the Boyne River.

"The stress preceded parasitic infestation during the colder winter water temperatures in 2011."

That infestation subsided as the water temperature increased and fish density reduced, as shown by improving fish health in late 2011 and 2012, the report said.

Significantly higher arsenic, cadmium, iron and zinc concentrations were found in barramundi livers in the Gladstone area, the report said.

That indicated the fish had greater exposure to metals and metalloids.

But no elevated levels of these metals were found in the tissues of diseased barramundi compared to healthy ones.

The report concluded metals and metalloids were unlikely associated to the fish health in the harbour.

Metal concentrations in crabs were found to be similar to crabs along the east coast.

"Overall, there is no strong evidence of a link between fish health at the time of sampling and tissue residue concentrations," it said.

YABBY farming is just like any other farming sector, according to yabby producer Trevor Domaschenz.

You have good years, you have bad years and you’re always at the mercy of the elements.

Yabby producer Trevor Domaschenz

Yabby producer Trevor Domaschenz

Prior to the breakdown of the Victorian yabby industry in 2004, Mr Domaschenz said he could grow up to four tonnes of yabbies a year, sold for a live weight of $10 a kilogram on farm or up to $15/kg in Melbourne during times of peak demand.

In the past most of his yabbies went overseas, some ended up in markets in Melbourne, with some going direct to restaurants.

“It’s different to other commodities, you’ve got to have the yabbies for the markets and consistently supply a good live product. You can never fill the market," he said.

This year, in his first year back in the human consumption market for some years with a more viable licence, Mr Domaschenz has much humbler ambitions.

“We just want to try to re-establish the yabby industry - ruined by regulations that make no sense - and hopefully sell a few this Christmas."

Central to a good season is getting sufficient rainfall to fill the turkey nest yabby ponds that cover around 25 hectares across his Patyah property.

"We are mainly sheep and grain farmers but yabbies can be very important to us in the wetter years that ruin our crops," he said.

“This one is shaping that way, we are the wettest we have been in the middle of July since 1996."

If the ponds have water, the yabbies will come up and breed. Once they have had time to grow out, Mr Domaschenz then catches them from boats in opera house nets.

“It’s the same as filling your household dam, we’re looking for good rain over the winter and spring to get enough water to fill the ponds.”

Once the yabbies are caught, they are taken into a storage shed for a period of purging - a requirement not necessary in other states.

“If we had our way, we’d store the yabbies in a holding dam in a large sock net, which is what they do elsewhere and is by far the best option for the yabbies themselves.

“Storing in a shed in summer is a backward step.”

Mr Domaschenz said getting involved in aquaculture had meant a steep learning curve .

“We initially got into it as a means of diversification and making use of our water in the late 80s.”

He said there had been a lot of work going into the location of the yabby ponds.

“We were always mystified as to why one swamp would be chock full of yabbies and one just down the road would have hardly any, and we think its because of soil type.

“They need free calcium for their shells they are very fussy about the conditions.”

Generally, there will be enough natural food for the yabbies, especially when the ponds are rotated over the seasons to allow the natural food sources to re-establish, but if feeding is required, Mr Domaschenz said lupins would be the preferred feed stock.

“If they didn’t eat them all, after a few days they float to the edge and don’t contaminate the water.”

There is still a lot to be learnt in terms of the humble yabby, Mr Domaschenz said.

“The trick is to get them to moult. Unlike fish, yabbies have to moult into a new shell.

“They absorb the calcium from their shell into little buttons in their head. Then they then grow a new shell, pump it full of water to the size they want and gradually replace the water with meat - during this stage they can nearly double in size.

“They then harden the shell from the button.”

Mr Domaschenz said a lot of research has been done into yabbies, but not many dams are suitable commercially - although the conditions found in his local West Wimmera shire were near ideal for yabbies.

“We reckon it’s the home of the yabby.”

Lobsters in Maine are bigger and there are more of them, the result of the last decade being the warmest ever on record in the Gulf of Maine. But a surfeit of good-sized lobsters has had unforeseen results. Not only are lobstermen seeing their profits decline as prices fall to levels last seen in the Great Depression, but lobsters are eating each other.

A Maine LobsterNoah Oppenheim, a graduate student in marine biology at the University of Maine, made the grisly discovery after sending down juvenile lobsters in traps outfitted with waterproof infrared cameras. Similar experiments conducted in the 1990s had found that, along with lobster traps, the main cause of lobster deaths was fish feeding on them. Cod and other bottom-dwelling fish (flounder and eels), crabs and seals all eat lobsters.

After Oppenheim’s recent experiments found that, 90 percent of the time, adult lobsters were eating the juvenile ones, a phenomenon not previously documented in the wild.

Lobsters can be said to be “opportunists” who will also eat another lobster if given the chance. They have been known to eat each other in captivity; the practice of putting rubber bands on their claws is more to protect them from each other. According to Oppenheim, this amount of lobster cannibalism he has recorded is unprecedented among lobsters in the wild.

A sort of perfect storm of events has created this situation. While the century average for gulf water temperatures was 47.6 degrees Fahrenheit, it has now risen to 50.7 degrees in just a few decades.  As Oppenheim explains to James West of Climate Desk, the warmer water has led to lobsters reproducing more quickly, having larger broods and growing more rapidly.

At the same time, cod, who are the natural predators of lobsters, have virtually disappeared from the Gulf of Maine, the result of overfishing; the cod population is at only 18 percent of the level that scientists estimate is needed to be healthy. Meanwhile, there is also an abundance of bait (fish such as herring) left in the thousands of lobster traps that smaller lobsters are able to escape from.

Ironically, the abundance of lobsters has not been a boon to those fishing the Gulf of Maine’s waters.  While as recently as 1987 lobsters only comprised 8.6 percent of Maine’s seafood catch, they now make up 40 percent of it — that is, the state’s fishing industry has become increasingly dependent on lobsters. At the same time, lobstermen are seeing their profits shrink dangerously as the abundance of lobsters drives down prices. As a result of climate change heating up Maine’s waters and the overfishing to meet rising demand for seafood, Maine’s fishing industry can be said to be cannibalizing itself.

Cannibalism has also been found among other animals as a result of the the recent rapid changes in global temperatures. Reports of adult polar bears killing and eating cubs in Canada have been said to be occurring more due to changes in the food supply. As a result of the melting of the sea ice, polar bears are spending more time on land and less on the ice where they can hunt seals; they are therefore turning to other sources of foodd.

Along with reports that endangered species may be turning to mating with siblings as their numbers have declined drastically due to habitat loss, the rise in lobster cannibalism that Oppenheim has found is yet another example of how nature is being transformed — too often in some highly worrisome ways — as a result of human activity. Genetically modified wheat and other plants have been called “Frankenfruit,” but they are hardly the only monstrosities resulting from climate change.

THE time to crack down on crab pot theft is now.

Professional Sarina Beach crabber Greg Sichter hopes to team up with Member for Mirani Ted Malone in a bid to install signs at boat ramps to alert fishers to the consequences of raiding pots.

"The signs will tell people there are surveillance cameras being used, and state what the fines are," Mr Sichter said.

The Daily Mercury reported Mr Sichter's business was being devastated, as his crab pots were being consistently raided, stolen or destroyed.

Mr Sichter eventually took matters into his own hands and set up surveillance cameras near his pots.

The cameras were successful in capturing two images of people raiding pots.

Sarina Police senior constable John Black said all of the adults in the photo had been identified.

"We are at the interviewing stages at this point of the investigation," he said.

"But all of the persons of interest have been contacted... I am confident charges will be laid and we will get an outcome."

Interfering with crabbing apparatus which is not your own is a serious offence and can incur fines of up to $55,000 or an on-the-spot fine of $1100. Mr Sichter said media attention had improved the situation for crabbers.

"I was just so stoked... I had gone back to crabbing a spot which I had avoided for years because it was hot for getting raided and nothing had been touched," he said.

"But when I was back at the spot I had the camera set up... someone had taken my crab pot and float," he said.

"That came as a kick in the guts."

AFTER nine years struggling to win accreditation to operate his yabby farm, Patyah farmer Trevor Domaschenz is angry with the lengths he had to go to be able to operate his business.

A Yabby“I’ve had two years in court to get what this Coalition government promised upon election then reneged on,” he said.

Mr Domaschenz has finally gained a licence to operate his farm and sell the yabbies for human consumption – but he is still upset, claiming industry regulator PrimeSafe and the Victorian Department of Environment and Primary Industries (DEPI) spectacularly mismanaged the situation, all but shutting down what was a lucrative business.

“According to CSIRO projections, we should have a $6 million per annum yabby industry in Victoria, but there’s only the shell of an industry left.”

Earlier this month Mr Domaschenz and Bellbrae farmer Stephen Chara won a case with the Victorian Civil and Administrative Tribunal (VCAT).

VCAT overturned a previous decision by industry regulator PrimeSafe not to grant the pair licences.

Mr Domaschenz, who farms near Edenhope in the west Wimmera, said Victoria was the only state to require licencing for the sale of live yabbies destined for human consumption markets.

He said the decision was the culmination of a fight that began in 2004 when PrimeSafe brought in a series of onerous regulations.

“We’ve had some rules in relation to purging of the live yabbies that no other yabby farmer in Australia has to adhere to.”

Mr Domaschenz also said current PrimeSafe requirements included out of date best management practices for the purging and storing of yabbies.

“They want us to purge the yabbies in a tub, rather than have them stored in prawn trays under fresh running water, which has been best practice for over 20 years.

“We would rather not purge at all - it is simply starvation.”

Aside from that, he said lines of communication had not been open with the regulator.

“When I was refused my licence by PrimeSafe I wasn’t told why, there was no explanation – I’d agreed to meet the standards they’d outlined in a meeting with them in Melbourne. The refusal was bizarre at best.”

Mr Domaschenz is so incensed by the performance of PrimeSafe and DEPI over the matter he is calling for a Royal Commission into its operation.

He is also running for an Upper House seat at next year’s State election as an independent, focusing on cutting unnecessary red tape.

“I’m not against rules and regulations, but there just hasn’t been any logical rationale behind what’s happening at PrimeSafe.”

For its part, PrimeSafe acknowledged VCAT’s decision.

“In relation to Mr Domachenz, VCAT set down conditions Mr Domaschenz was required to fulfill to be granted a Prime Safe licence, and Mr Domaschenz has fulfilled the VCAT conditions and is now licenced,” said acting PrimeSafe chief executive Brendan Ryan.

Mr Domaschenz said Mr Ryan’s interpretation obscured VCAT’s decision, saying VCAT had not set out any new conditions and had in fact thrown out PrimeSafe's astonishing conditions.

“VCAT granted me the license PrimeSafe had refused me, they ordered PrimeSafe to issue a licence to me with the same conditions I applied for and that they refused previously.

“They said PrimeSafe could not refuse the licence if I applied the same way I had before.”

For its part, VCAT questioned PrimeSafe’s purging regulations and questioned why it had never sought independent advice on food safety standards.

Mr Domaschenz said the victory was somewhat hollow, as all other yabby farmers had been forced to exit the industry since the PrimeSafe regulations came into effect.

“There were over 60 licences across Victoria selling yabbies for food plus another 150 odd supplying those licences - now there is only me."

Mr Domaschenz said he was also disappointed the VCAT ruling did not constitute a legal precedent for others going for a licence to sell yabbies for human consumption.

“It’s a been a long road, literally, I’ve had two years of trips up and down to Melbourne.

"And even though we’ve got there (in the end), why did I have to go to Melbourne eight times to get less than what the minister for ag promised me two years ago?"

Looking at the positives, Mr Domaschenz said he was pleased to have the certainty to take orders for the busy Christmas period.

“We’ll have yabbies to sell by the end of the year.”

AN Australian scientific breakthrough is being heralded as delivering the unprecedented double benefit of preserving depleted wild fish stocks in the world's seas while also making prawn farming more profitable and environmentally sustainable.

CSIRO marine scientists at Queensland's Bribie Island aquaculture research station have discovered that prawns - and potentially farmed fish such as salmon and barramundi - can be grown without a diet of which one-third is based on eating krill, fish oil and other wild fish species from the ocean.

Instead, CSIRO has pioneered a natural way of growing large quantities of tiny marine microbes commercially in large salt-water ponds, and using these naturally occurring ocean microbes together with a mix of soybean, other plant proteins and trace minerals to raise the farmed prawns.

Besides saving dwindling wild fish stocks at the bottom of the natural ocean food chain that should be consumed by whales and sharks, the natural marine microbes traditionally eaten by wild prawns also contain an active ingredient that sparks farmed prawns to grow 30 per cent faster.

Head of the CSIRO Food Futures flagship, marine biologist Nigel Preston, said the 10-year discovery and development of how to produce the new aquaculture feed would help a commercial industry and the environment make a quantum leap forward.

"I've been in this game for 30 years and there is no doubt in my mind this is the most important discovery we have made, and it is Australian knowledge that will have a major global impact," Dr Preston said.

He predicts the non-fish-based feed system is so advantageous that the new pellets containing the secret marine microbial ingredient novacq (short for novel aquaculture feed) will be in wide use in Australia's $75 million prawn farming industry within two years.

Dr Preston said the world-first discovery, which will be unveiled this morning at the Australian Prawn Farmers Association conference in North Queensland, also gives prawn-loving consumers access to more sustainably produced prawns that still have the same high quality and taste.

"This is a game changer for the industry and consumers," Dr Preston said. "We fed pellets containing novacq to farmed black tiger prawns, and it made them grow and taste even better for consumers, the environment and prawn farmers."

Until now, about one third of the 90 million tonnes of seafood caught from the world's oceans annually is estimated to have been used to feed farmed fish and prawns.

Australian company Ridley AgriProducts has bought the patent to grow the novacq microbes and produce the non-fish pellets in Australia and Southeast Asia.
