On the 29th December 2009 our news blog with over 2000 entries was taken down by blogger on suspicion of it being a `spamblog`. Whether this was as a result of malicious intent by persons unknown (well, we know perfectly well who they are, but you know what I mean), or as a result of over zealous spambots.

Kylie Minogue congratulates giant carp catcher on Twitter

Kylie Minogue praised hero angler Martin Locke after he caught a giant carp which weighed the same as the princess of pop.

Published: 4:04PM GMT 12 Jan 2010

Mr Locke braved sub-zero temperatures in just a T-shirt to break the world record for catching the biggest ever carp a 94 pound whopper.

The enormous mirror carp weighed the same as Minogue and beat the previous record by 3lbs.

Angling records and their celebrity equivalents

After reading about his feat on Telegraph.co.uk she Tweeted: "Hahaaaa congrats Mr Locke!!"

Brit Mr Locke jumped out of his lakeside tent at 6am in temperatures of -3C to net the monster fish that tipped the scales at 94lbs.

Angling records and their celebrity equivalents
Wearing only a T-shirt and trousers, he jumped in his boat and motored 200 yards out to the fish and began reeling it in.

At first he thought he had hooked a sunken tree trunk due to the weight of it but was gobsmacked when he heaved the carp to the surface.

Getting it in his landing net was like 'trying to land a small hippo with a tennis racket,' but after succeeding he towed it to the shore to weigh it.

Despite the early hour and freezing temperatures, many other anglers gathered round to celebrate with the new record holder.

Mr Locke, from South Darenth, Dartford, Kent, left the fish in the shallows until daylight when he photographed the aquatic beast before returning it to the lake in good health.

Fish 'acts like Lord Sugar when dealing with subordinates'

A species of fish exhibits traits similar to Lord Sugar when dealing with subordinates who fail in a task, new research has shown.

Published: 7:30AM GMT 08 Jan 2010

Cleaner wrasse, which live on reefs, provide a valuable service by feeding on the parasites of ''client'' fish.

Males are in charge in communities of cleaner wrasse and the new research shows they have much in common with their ''Lord Sugar'' style human counterparts.

Like the belligerent Amstrad founder and boss on the television show The Apprentice, male cleaner wrasse will not tolerate failure.

When the females fall down on the job by offending a client, they are chased aggressively by the angry males.

The behaviour is an unusual example of animals delivering a ''third-party punishment'' for misdeeds that do not directly affect them.

Although cleaner fish pick parasites off their larger reef-mates, they can get a bigger meal by taking a bite of the mucus on a client's skin. However this is seen as an offensive ''cheating'' act, and likely to drive the ''customer'' away.

Any female spotted committing such a flagrant breach of the rules provokes a sharp reaction from the boss.

The boss/employee relationship between male and female cleaner fish was investigated in the laboratory by scientists led by a team from the Zoological Society of London.

A plate full of ordinary food and more tempting prawns was offered to the fish, but removed whenever one of them ate a prawn.

Researchers quickly saw that males would chase females who could not resist the prawns, thereby causing the food plate to be lost. After being punished, the females were less likely to eat a prawn again.

The study, reported in the journal Science, shed light on what occurred between the fish and their ''clients'' in nature.

Dr Nichola Raihani, from the Zoological Society of London, said: ''Clients will leave if they are cheated at a cleaning station. That means the male's dinner leaves if the female cheats. By punishing cheating females, the males are not really sticking up for the clients but are making sure that they get a decent meal.''

Japanese fisherman catches 22-pound bass

By THE ASSOCIATED PRESS

DANIA BEACH, Fla. - A Japanese man is being credited with tying the 77-year-old world record for catching the biggest largemouth bass.

The International Game Fish Association announced Friday that it had confirmed the 22-pound, 4-ounce fish caught by Manabu Kurita. The Florida-based group said Kurita caught the fish July 2 on Lake Biwa, Japan's largest lake.

Kurita's fish tied the record of George Perry, who caught his bass on Georgia's Montgomery Lake on June 2, 1932.

Kurita used 25-pound test line and a live blue gill as bait.

Electric ray gives birth to 16 babies

A rare electric ray has given birth to 16 babies at a sealife centre.

Published: 8:00AM GMT 09 Jan 2010

It is believed to be the first time the marbled electric ray - which can give a shock almost as strong as mains power - has given birth in captivity in Britain.

The baby rays are in good health and feeding happily on slivers of squid in a nursery tank at Brighton Sealife Centre in Brighton, East Sussex.

The mother was delivered to the centre in September by a local fisherman who was surprised to find the ray among his catch.

Marbled electric rays, or Torpedo marmorata, are usually found in the Mediterranean.

Curator Alex Gerrard said: "She settled in well, but started to go off her food mid-way through December.

"We were worried she might be ill but realise now it was because she was ready to go into labour."

The mum is the size of a large dinner plate and her babies are each as big as the bottom of a coffee cup.

Man-Eater Shark Spines 'To Be Severed'

7:03am UK, Sunday January 10, 2010
Huw Borland, Sky News Online

Sharks that attack swimmers will be hunted down, shot in the head and sawed apart until their spines are severed, according to reports.

Perth's Sunday Times revealed the gruesome methods for dealing with man-eaters approved by the Government of Western Australia.

A shark that attacked a swimmer would be slaughtered if it continued to pose a threat to beachgoers, WA Department of Fisheries's Tina Thorne was quoted by the paper as saying.

But the kill order would only be given in "extreme circumstances", as a last resort where there was an immediate danger to the public.

Ms Thorne said fisheries officers would first use a baited drumline and put "attractant" in the water to try to hook the shark.

The creature would then be hauled aboard a boat where officers would "have to use a large firearm to dispatch the animal".

"That is not an easy task, as sharks have very small brains," she said.

Once shot through the head, officers would ensure the creature was dead by "severing the spinal cord and bleeding it out".

"Even if you hook it, you can't just fly over in a chopper and shoot it because of refraction (of the bullets) in the water," Ms Thorne said.

But great whites - the species responsible for most fatal attacks - are protected and a special exemption from the law is required to kill one.

Six people have been killed by sharks in Western Australia in the past 20 years, the paper added.

The giant Amazon arapaima fish is 'under threat'

By Matt Walker
Editor, Earth News

The arapaima, a giant species of fish that lurks in the Amazon river, may be threatened by overfishing.

Studies reveal that errors in the classification of the species could mean that it is being pushed closer to the edge of extinction than thought.

The arapaima is the largest freshwater fish with scales in the world.

But there may actually be four species rather than one, say scientists, and a lack of research and management may allow some to be fished to extinction.

The threat to the future of these fish has been revealed in research conducted by Dr Leandro Castello of the Woods Hole Research Center in Falmouth, Massachusetts, US, and Professor Donald Stewart of the State University of New York in Syracuse, US.

They have reviewed what is known about populations of the arapaima, and conducted detailed investigations into the status of the fish in the wild.

Previously, it was thought there was one species of arapaima (Arapaima gigas), which also goes by the common names pirarucu or paiche.

This perspective is based on a taxonomic review done over 160 years ago.

Adults grow to almost 3m in length and can weigh more than 200kg, making the fish the largest with scales living in freshwater anywhere in the world.

They are also air-breathers, coming to the surface every 5 to 15 minutes to gulp air, a behaviour which allows them to colonise muddy oxygen-poor rivers and lakes within the Amazonian basin and prey on other fish that find it difficult to move in such conditions.

However, in an ongoing study, Prof Stewart has analysed nearly all preserved specimens of supposed arapaima available in museums in the world.

So far he has only found one specimen of Arapaima gigas.

The others are suspected to be closely related species, including some as yet unreported.

"Our new analyses indicate that there are at least four species of arapaima," says Dr Castello.

"So, until further field surveys of appropriate areas are completed, we will not know if Arapaima gigas is extinct or still swimming about."

Concern about the fish's numbers comes from other work done by Dr Castello and Prof Stewart.

That suggests that arapaima sexually mature relatively late, and need very specific habitats to both live and reproduce.

Their research also shows that populations of the fish are being put under severe pressure by fishermen.

Because of the fish's huge size and habit of coming to the surface, it has long been a favoured fish to catch, with fisherman using harpoons and gill nets to land their prey.

"They have the curse of being tasty and of having to breathe air," says Dr Castello.

Fishermen have been catching large numbers of arapaima in this way since the 1800s.

But now, while a few populations are increasing, others are being overfished, say the researchers, who have published a paper warning of the fish's fate in the Journal of Applied Ichthyology.

And while Brazil implemented regulations to manage arapaima fisheries some 20 years ago, most fishermen do not follow the regulations, say the authors.

"Arapaima can be viewed as badly overexploited and under some level of threat of extinction," says Dr Castello.

One solution, they say, is to encourage community-based schemes for fisheries, and there is much need for additional action on the part of the government.

For example, their research shows that fishermen who specialise in hunting arapaima with harpoons can accurately count the fish, due to the fish's habit of breaching the surface for air.

The fishermen can then select a sustainable proportion of the population to hunt.

"Populations of arapaima managed with this system increased about 50% annually, while yielding increasing catches and hence economic profits to the fishermen," says Dr Castello.

Around 100 such community schemes are in place, and some previously overexploited populations have recovered.

"Such results are extremely rare in wildlife conservation, especially in tropical countries where wildlife conservation challenges are greater than elsewhere," says Dr Castello.

But much more needs to be done to research these fish in more detail and prevent overfishing, the scientists warn.

In particular, "the present situation may be one in which one species of arapaima is recovering in certain areas, while unrecognised species are going extinct," they say.

Sharks need friends

By danielclark, YourNews contributor
Posted January 4, 2010

SEBASTIAN — Sharks - demons of the sea - or a diverse group of animals that deserves an image makeover?

Marine biologist Hannah Mead will change your perception of them in "Even Sharks Need Friends," a presentation of the Turtle Coast Sierra Club at the Library in Sebastian on Jan. 19, at 7 p.m.

Mead will show you what makes a shark a shark, and how those traits make them susceptible to overfishing. Emerging evidence suggests that the use of unsustainable fishing practices, like long lining and a profitable market for shark fins, are causing the depletion of local and global shark populations.

Mead earned dual degrees in Marine Biology and Ecology from Florida Tech. She recently returned from living in South Africa, where she earned a Master's degree in Zoology from the Marine Biology Research Institute at the University of Cape Town. All of her free time was spent at sea with white sharks, either tagging/observing them for governmental and PhD projects, or as an onboard scientist for a commercial cage diving company, promoting education and conservation among the clients.

Her free time was also spent catching shy sharks for research or cruising with the cow sharks off the Cape peninsula and the whale sharks of Mozambique. Being immersed in such a "sharky" community solidified her commitment to research, and their conservation.

Admission to this program is free and open to the public. A social hour with refreshments begins at 6:30 p.m. The North Indian River County Library is located three miles west of U.S. 1 on Sebastian Boulevard. Call (772) 589-1355 for more information.

Weymouth Sea Life 'dragons' fall for mistletoe

9:40am Tuesday 29th December 2009
By Martin Lea

MISTLETOE has tricked leafy seadragon creatures at the Sea Life Park in Weymouth into a mating frenzy after they confused the Christmas plant for a love-rival.

The odd-looking marine creatures bear a striking resemblance to the Christmas kissing plant.

So when the males were a little slow in getting to know the female seadragons at an aquarium, staff decided to decorate their tank with sprigs of mistletoe.

And it had the desired effect as it apparently sparked jealousy in the male seadragons who now see the plant as a love rival.

Fiona Smith, display supervisor at the Sea Life Park, said: “The males have suddenly started engaging in heated courtship with the females.

“It seems the males view the Christmas decorations as potential rivals and they are making sure they don’t lose out.

“We knew the seadragons looked like mistletoe and at first we decorated the tank as a bit of fun but it has had the desired effect.

“It looks like mistletoe can fire underwater passions so we may keep it in the tank year round.

”The Sea Life Park hopes to be the first place in Europe to breed the animals that are usually found around Australia.

The attraction has only recently taken delivery of the creatures, but were not encouraged with their initial lack of courtship.

Seadragons – phycodurus eques in Latin – are close relatives of seahorses and like them, it is the male that looks after the eggs by carrying them in a clump on his belly.

The Sea Life Park is one of the world’s most successful seahorse breeding facilities and its marine experts hope their expertise will guide them to similar success with the seadragons.

Lifeguards to get texts from approaching sharks

December 31, 2009 7:52 AM

Australian lifeguards will soon get text messages when Great White sharks swim near the beaches they are patrolling.

Researchers are electronically tagging the man-eating predators with GPS units which will constantly monitor their movements.

If the sharks then get too near to a beach a satellite receiver will automatically send out emails and text messages to wildlife officials and lifeguards.

Currently 74 white sharks have been tagged and there are 20 communications-equipped monitoring stations have been installed off the Perth coast.

Bosses say they hope the network will "provide timely alerts of tagged sharks' presence close to beaches" -- obviously this is unless the lifeguard is busy playing a game on his phone at the time. Australian Department of Fisheries’ Senior Research Scientist Dr Rory McAuley said: "With more monitors installed we have improved chances of hearing from tagged sharks, when they are around.

"Although sharks are being tagged to improve our understanding of the risk of attacks, it is also important that beachgoers are advised of detections."
