Human digits came from fish, study says
Prehistoric 'finger' fins found in an Australian fish species led to the development of digits in humans, new research suggests.
Zerina Johanson, palaeontologist at London's Natural History Museum, said the small fin bones of Neoceratodus - also known as the Australian or Queensland lungfish - are much the same as fingers and toes in modern back-boned land animals.
"Where our fingers came from has been one of the biggest mysteries surrounding the move of our evolutionary ancestors from sea to land," Dr Johanson said.
The study, which also involved lungfish expert Jean Joss from Australia's Macquarie University, supports the findings of similar research into the evolution of fish fins into the limbs of tetrapods, or four-legged animals.
"How we got from a fish fin to a tetrapod hand, it seemed like a very substantial change," Dr Johanson told AAP.
"Now, with our research and the research of others, that gap is becoming narrower and narrower.
"There is not really that much of a difference between a fin and a limb anymore."
The development of fingers and toes in the embryos of land animals is closely linked to a particular gene, which acts in a distinctive pattern.
The study found an almost identical pattern in the fins of the Australian lungfish, suggesting digits are the equivalent of fin bones.
"We have a case of fish fingers in the Queensland lungfish," Dr Johanson said.
The Queensland lungfish is known as a living fossil because it has survived since first appearing on the fossil record more than 100 million years ago.
It is part of the lobe-fin group, which are the closest living relatives of land animals.
Australian lungfish occur naturally in just a few coastal river systems in south-east Queensland.
Earlier this month, Queensland Premier Anna Bligh announced a $35 million Freshwater Species Conservation Centre would be built near Gympie, aimed at ensuring the survival of the lungfish, Mary River cod and Mary River turtle.

Fishing ban lifted for SE lake
Fishing is to be allowed on Lake George in the south-east of South Australia for the first time in since 1999.
Fisheries Minister Rory McEwen says a moratorium will be lifted on Friday.
He says a survey found fish stocks had increased in the lake, north of Beachport.
In 1999, the water quality in the lake deteriorated, causing fish to die.
Large stocks of yellow-eye mullet were caught during a survey of fish numbers in Lake George back in August.

Novel fishing method finds rare fish
A novel way of catching fish - stunning them with an electric current - has helped Northern Territory researchers rediscover a rare species.
The Lorentz's Grunter (Pingalla lorentzi) was found again during a study into northern Australian freshwater fish in the Finnis River near Batchelor.
It had not been seen in the region for 14 years.
"The rediscovery of this particular fish is significant," Primary Industry and Fisheries Minister Chris Natt said.
"It helps to build an accurate picture of our ecosystems and assists in making science-based management decisions for our waterways."
The Grunter was also found by the researchers at another site on the Finnis River, more than 40km from the original site near Batchelor.
"It appears that this Grunter is more widespread than we initially thought," Mr Natt said.
The research is part of a three year analysis of the freshwater fish fauna of northern Australia.
Mr Natt said much of the success of the study was related to the NT government's $25,000 electrofisher, which works by supplying an electrical current to the water.
It temporarily stuns the fish, allowing researchers to capture and identify them unharmed.
"The project aims to look at freshwater fish in northern Australia and how we should manage our rivers and streams to maintain healthy fish populations," Mr Natt said.
"Fisheries researchers are also hoping to find new freshwater fish that we find to also expand our knowledge of what fish we have in the NT."
The project is coordinated by James Cook University and funded through the Natural Heritage Trust for $161,500.

Tuna fishermen told of albatross crisis
An international meeting of southern bluefin tuna fishing nations will be told on Tuesday that the annual bycatch of endangered albatrosses is an ecological disaster.
The Humane Society International (HSI) says 10,000 of the 13,500 seabirds estimated to die every year on longline fishing vessels targeting southern bluefin tuna are species of albatross.
The Commission for the Conservation of Southern Bluefin Tuna (CCSBT) is holding its annual meeting in Canberra this week, with countries like Australia, Japan, Korea, New Zealand and Taiwan attending.
HSI spokeswoman Nicola Beynon said the CCSBT management area coincides with the distribution of 17 of the world's 24 albatross species, the world's most endangered group of birds.
The conservation group has observer status at the meeting.
"HSI hopes to be able to address the commission to deliver a warning that they must clean up their fishing practices or end up being responsible for the extinction of some of these magnificent birds," Ms Beynon said in a statement.
"In the last 10 years they have not been able to agree to any new measures to prevent the capture of seabirds on the longlines most of these countries use to target SBT.
"Among other things, HSI will ask that the commission agrees to weight their lines so that their baited hooks sink quickly out of the reach of seabirds, or to set their lines at night."
Ms Beynon said longline fisheries targeting southern bluefin tuna were also suspected to be killing marine turtles and tens of thousands of sharks. The southern bluefin tuna is classified as a critically endangered species.

Sleeping with the (insomniac) fishes
FISH might not have eyelids, but they do sleep, and some suffer from insomnia, scientists reported today.
California scientists studying sleep disorders in humans found some zebrafish, a common aquarium pet, have a mutant gene that disrupts their sleep patterns in a way similar to insomnia in humans.
Zebrafish with the mutant gene slept 30 per cent less than fish without the mutation. When they finally drifted off, they remained asleep half as long as the normal fish, the researchers at the Stanford University School of Medicine said.
The mutant fish lacked a working receptor for hypocretin, a neuropeptide that is secreted in normal fish by neurons in the region of the brain that controls hunger, sex and other basic behaviours.
Zebrafish, also known as zebra danio, have become popular research subjects because they are cheaper to breed than mice and they have a backbone that better represents the human nervous system than fruit flies.
The researchers, led by Emmanuel Mignot, said they would look for fish with a mutation that causes them to oversleep or never sleep in the hope of discovering if sleep-regulating molecules and brain networks developed through evolution.
"Many people ask the questions, 'Why are we sleeping?' and, 'What is the function of sleep?'" Mr Mignot said.
"I think it is more important to figure out first how the brain produces and regulates sleep. This will likely give us important clues on how and maybe why sleep has been selected by natural evolution and is so universal."
The study was published in the Public Library of Science-Biology.

Woman fights off white pointer at Byron Bay
A WOMAN has survived an attack by a large white pointer shark at Byron Bay on the NSW far north coast.
The shark knocked the woman out of her surf ski but she fended it off and returned to shore with only an arm wound.
The woman was attacked mid-morning at a well-known surf break known as The Pass, a police spokesman said.
"The shark is described as being an eight to nine foot (about 2.5m) white pointer, and it has knocked her off her surf ski," he said.
"It has then come at her and she has been able to fend it off. At that stage it appears she suffered an injury to her right arm.
"She has been able to climb back into her surf ski and has made it back to shore."
She was taken to hospital and boats were looking for the shark.
People were advised not to go in the water.
Today's attack comes after a tourist was bitten by a shark in remote waters off Cairns
The bronze whaler sank its teeth into the 31-year-old man’s leg as he swam for a charter boat with a fish and his spear gun in his arms at Holmes Reef, about 240km east of Cairns, just before noon on Saturday. .

OMG Mark!!
That HAS to be the worst tale of woe roadtrip ever.
I am so sorry your whole family came down with the lurgy
right when you plan a weekend like that.
When I was reading your report, I felt I was watching one
of those NRMA Insurance ads where disaster unfolds before
your eyes.
I hope you can manage a quick fish, maybe after work to get back your mojo.
I hope work today is better than your weekend..It can't be worse.
Cheers,
Pete.

It will stand for a while I expect, until you get hold of
her grandmother.
Don't forget to enter the old girl in the FOTM.
Cheers and well done...a great holiday.

Penguins take fishing trips with their buddies
Penguins make bosom buddies and they like to team up with them when going on fishing expeditions.
Little penguins, the smallest penguin species, go on long fishing trips to feed their chicks. Like many other penguins they cross the beach in groups of five to 10 birds, as being in troops helps protect individuals from predators. The suggestion is that these groups fish cooperatively, in which case you might expect the birds to seek out good teammates rather than form groups at random.
To find out, researchers led by André Chiaradia of the Philip Island Nature Park in Victoria, Australia, recorded arrivals and departures of little penguins over four consecutive breeding seasons, identifying the birds by means of a microchip placed under their skin.
This showed that they did tend to team up with the same fishing partners, perhaps because it helps to buddy up with penguins that share knowledge of particular feeding sites, for instance. However, only middle-aged penguins did so, and then only when food was abundant and a large number of chicks had fledged that year.
In years when food was scarce the birds were less choosy, perhaps because they were fishing alone to avoid sharing scarce resources. Older and young penguins, both of which are likely to be less good fishers, were never picked to be part of a team.

Will, contact Darren @ Trailer Boat Hire and he will deliver a 4.2 quinnie to you or you can pick it up with a sounder.
You must have a boat license to drive these boats as they are quite powerfull and go well over the 10 knots .
Cheers Stewy
Will...Darren's boats also have a Scotty downrigger on them so you can chase some kings
around Pittwater too.
I've hired Darren's boats 4 times now and can vouch for the quality of his boats and the service (plus the generous Fishraider member discount).
Cheers,

Salmon fisherman takes on Donald Trump
US billionaire Donald Trump is a man who usually gets what he wants, but a Scottish salmon fisherman is standing firm against his plans to build a luxury golf course resort.
Trump wants to build two championship courses, a 450-bedroom hotel and 950 holiday homes on land near Balmedie, just north of the city of Aberdeen, in northeast Scotland.
But Michael Forbe's ramshackle farm lies slap bang in the middle of the proposed second hole and the site of a planned eight-storey five-star hotel – and the 55-year-old is refusing to be bought out.
The row has echoes of the cult 1983 film Local Hero, in which an astronomy-obsessed US oil billionaire earmarks a picturesque Scottish fishing village as the site of a new oil and gas development.
In the film, locals are happy to cash in, but a wily, beach-dwelling hermit refuses to sell. The boss's right-hand man, sent to seal the deal, falls in love with the village and eventually persuades him to set up a marine observatory instead.
Pennan, where the film was shot, is just up the coast from Balmedie.
A war of words has erupted between Trump and Mr Forbes, with the US developer reportedly accusing the ruddy-cheeked fisherman this week of keeping his 9.3-hectare smallholding in a state of "total disrepair".
The Aberdeen Press and Journal newspaper today reported that Trump said Mr Forbes was deliberately keeping the property in a state of wrack and ruin as a ploy to get more money.
Mr Forbes hit back, telling the newspaper the £350,000 ($A794,550) he was offered was well below the market value.
"It's mine and I'm keeping it. He's not used to people saying 'no' to him," said Mr Forbes, whose grandfather and uncles fished from the same spot on the North Sea coast.
Another potential stumbling block for Trump is an environmental campaign against any construction on "green belt" land – countryside areas – protected from development in law. A march is planned in Aberdeen on Saturday.
Trump's right-hand man George Sorial said Mr. Forbes was "playing a little game" to get more money, but said the farmer was entitled to stay.
"We're not going to hide the fact that we would like to purchase his land and have made offers, but we don't need his land."
