LONDON After nearly quarter century camping out by the banks of Scotland's Loch Ness hoping to glimpse "Nessie", the most dedicated hunter of the legendary monster has given up, concluding it is just a very big catfish. 
  
 Steve Feltham, who gave up his girlfriend, house and job in southwest England in 1991 to spend his life looking for the Loch Ness monster, believes he has solved the mystery behind its many sightings, the Times newspaper reported on Thursday. 
  
 Rather than being a primeval beast, he suspects it is a Wels catfish, a native European catfish that the paper said could grow up to 13 ft (4 meters) long. Victorians introduced the fish to the dark waters of the loch to provide sport. 
  
 "I have to be honest. I just don't think that Nessie is a prehistoric monster," Feltham was quoted as saying. "What a lot of people have reported seeing would fit in with the description of the catfish with its long curved back." 
  
 His conclusions are unlikely to deter the thousands of tourists who visit the site and believe a monster does still lurk in the dark waters of the deep Scottish lake. 
  
 The first written record of the monster relates to the Irish monk St Columba, who is fabled to have banished a "water beast" to the depths of the River Ness in the sixth century, long before the introduction of the catfish to the loch. 
  
 There have been countless fruitless attempts to track down the monster in the years since. In 2003, the BBC funded an extensive scientific search that used 600 sonar beams and satellite tracking to sweep the full length of the loch. It concluded there was probably nothing there. 
  
 The most famous picture of "Nessie", known as the "surgeon's photo", was taken in 1934 and showed a head popping out of the water. It was revealed 60 years later to be a hoax that used a sea monster model attached to a toy submarine. 
  
 "The monster mystery will last for ever and will continue to attract people here, monster or not," Feltham said. "I certainly don't regret the last 24 years."

 But now Steve Feltham, who is recognised by the Guinness Book of Records for the longest continuous monster hunting vigil of the loch, believes Nessie is no plesiosaur but a giant catfish first introduced by Victorians. 
  
 And what is more, there may be only one ‘Nessie’ left. 
  
 Mr Feltham’s “Nessie no more” verdict - which he said had been “a long journey” of realisation - could be devastating to the Loch Ness Monster tourism industry, which is said to be worth around 25 million-a-year to the area. 
  
 More than 85 per cent of the estimated one million visitors are attracted by the phenomenon of the Loch Ness monster - many to visit Mr Feltham - and Nessie has her celebrity fans too. 
  
 Two years ago Hollywood hellraiser Charlie Sheen even went to look for Nessie - allegedly armed with a leg of lamb and a large hook - and promised to return with American ex chat show host Jay Leno.

 But Mr Feltham, 52, said he was now convinced that Nessie was a Wels catfish - a giant fearsome fish that can grow as long as 13ft and up to 62 stone. 
  
 “It is known they were introduced into English lakes by the Victorians for sport. They are very long lived and it is entirely possible they were introduced by Victorians to the loch - which would explain why the main sightings of Nessie really started in the 1930s - just as the animals were reaching maturity,” said Mr Feltham, who gave up his girlfriend and home in Dorset to hunt for Nessie. 
  
 “There was a viable breeding population but I think the numbers have declined to the extent that there are now just one or two left. They also eat other catfish and may have eaten breeding females over time. Nessie is destined to be no more, I’m afraid. 
  
 “I’ve had to change my mind slowly over time, but what a lot of people have reported seeing would fit in with the description of the catfish with its long curved back.

 “Its natural decline in numbers over time would also explain the tail off in sightings in recent years. I have to be honest. I just don’t think that Nessie is a prehistoric monster. However the monster mystery will last forever and will continue to attract people here - monster or not. I certainly don’t regret the last 24 years.” 
  
 The legend of the Loch Ness Monster has been around since the sixth century, when Irish monk Saint Columba witnessed locals burying a man who had been attacked by a ‘water beast.’ 
  
 Sightings were scarce until the first modern newspaper report of a monster in the Northern Chronicle of 27 August 1930 which told of fishermen in a boat on Loch Ness being “disturbed” by a 18 feet long creature. 
  
 But it was the famous sighting in 1933, when George Spicer and his wife claimed they saw ‘a most extraordinary form of animal’ which was 4ft high and 25ft long crossing the road near the loch, that started Nessie mania.

 The following year, Dr Robert Kenneth Wilson took a picture - the most famous picture of the monster - although it was later revealed to be a hoax made with a toy from Woolworth’s. 
  
 And in 1935, renowned big game hunter Marmaduke Wetherell found a footprint he said was the monster’s. It was later revealed to have been made by him using a dried hippo’s foot of the type used as umbrella stands at the time. 
  
 Nessie has also spawned countless books and films - among them Loch Ness, starring Ted Danson and Joely Richardson. 
  
 Mr Feltham, who has spent nearly quarter of a century looking for the elusive beast, has had few encounters himself. He said it showed up on the one day he didn’t have his camera on him. 
  
 Mr Feltham left his job fitting security cameras and his home in Dorset to move to the banks of Loch Ness and devote his time to searching for the legendary monster in 1991. 
  
 After two years of patiently scanning the loch, Mr Feltham said he finally caught a glimpse of Nessie, but he didn’t have his camera to hand.

 Since then, he has kept a careful watch on the waters of the loch, but she has not shown herself again. However, he is now convinced Nessie is a giant catfish. 
  
 The Wels catfish, also called sheatfish, is native to wide areas of central, southern, and eastern Europe, and near the Baltic and Caspian Seas. It has been introduced to Western Europe and is now found from the UK all the way east to Kazakhstan and south to Greece. It is a scaleless fresh and brackish water fish recognizable by its broad, flat head and wide mouth. Wels catfish can live for at least 30 years and have very good hearing. 
  
 Their wide diet even includes other catfishes. The larger ones also eat frogs, mice, rats, and aquatic birds like ducks. They have also been observed lunging out of the water to grab pigeons on land. 
  
 Exceptionally large specimens are rumored to attack humans in rare instances, a claim investigated by extreme angler Jeremy Wade in an episode of the Animal Planet television series River Monsters following his capture of three fish, two of about 145lb and one of about 160lb, of which two attempted to attack him following their release. 
  
 A Wels catfish was reported in 2009 dragging a fisherman near Gyr, Hungary, under water by his right leg after the man attempted to grab the fish in a hold. He barely escaped with his life from the fish, which must have weighed over 220lb, according to the fisherman 
  
 Last year a fisherman has caught a giant 8ft 9in long catfish weighing 19 stone - which could be the biggest ever caught with the humble rod and line. 
  
 Dino Ferrari hooked the huge Wels catfish in the Po Delta in Italy. 
  
 Sightings of Nessie have become scarcer, but so far there have been three this year. 
  
 The last one logged on the official Loch Ness Monster Sightings Register was on April 25. Dee Bruce of Elgin was driving to Skye with her partner Les Stuart when she saw a black creature come about three feet out of the water near the north end of the loch. It happened so quickly, she was unable to get a camera out to take pictures. 
  
 Two days earlier, a couple on visiting Urquhart Castle - above Nessie’s rumoured lair - reported seeing a large dolphin sized shape emerging from the waters. 
  
 Mr Feltham, who said he became obsessed with the legend of Nessie after a family holiday to the Highlands when he was seven, lives in a converted mobile library which is parked in a pub car park near the loch at Dores. 
  
 “At least my search for Nessie has given me the best view of the world,” said Mr Feltham, who makes money by creating models of the Loch Ness Monster and selling them to tourists. 
  
 Mr Feltham has become such a feature of the loch that he is even a member of the local community council. 
  
 “Film crews and journalists from all over the world turn up on a regular basis, and I answer all their questions, but they are invariably focused on one subject: is there a monster, or isn’t there? Which is perfectly understandable, but it frustrates me that I never have the chance to get an equally important point across: that if you have a dream, no matter how harebrained others think it is, then it is worth trying to make it come true. I’m living proof that it might just work,” he says on his website. 
  
 “Have I ever regretted my decision? Never, not for one second.” 
  
 • Have you visited our new Scottish food and drink site? ||||| The Loch Ness monster is most likely a large catfish, according to an expert who has spent 24 years searching for Nessie. 
  
 Steve Feltham, 52, gave up his home, his job and his girlfriend to move nearer the Scottish loch in pursuit of the legend. 
  
 Speaking to Sky News, Mr Feltham did not claim he had solved the mystery of Nessie. 
  
 But he said: "Looking at all the evidence, speaking to eyewitnesses, the most likely solution is a Wels catfish." 
  
 The fish can grow up to four metres (13ft) long and weigh over 400kg (880lb). 
  
 There have been various photographs over the decades of a strange object in the water, leading to claims of a monster there.

 One infamous black and white picture of a head and neck peering out of the water in 1934 was later revealed as a hoax by one of the people who staged it. 
  
 Mr Feltham claimed that sonar contact had picked up objects in the loch that were the size of an estate car. 
  
 This was even though the biggest creatures known in the loch were salmon and seals that sometimes chase them. 
  
 "We get sonar contacts with things that are far bigger than any fish that should live in this body of water," he said. 
  
 And he admitted: "We only get one or two decent sightings a year." 
  
 This photo of Nessie was later revealed as a hoax 
  
 Mr Feltham said he had no regrets about dedicating nearly a quarter of a century of his life to try to solve "one of the world's greatest mysteries". 
  
 "I'm in my utopia living here on the shores of the loch," he said. 
  
 He holds the record for the longest continuous vigil hunting for the Loch Ness monster and he predicted he could continue his search for another decade. 
  
 He said: "I'm not saying the mystery's solved. I'm still looking for a better explanation than that (Wels catfish). 
  
 "This is an explainable phenomena. There is something to be explained in Loch Ness." ||||| Fishermen are known for their tall tales of big catches. Turns out, this one has a lot of truth to it: Italian fisherman Dino Ferrari caught this monstrous 280-pound catfish on the Po River. 
  
 Catfishes range in size from a few inches to a few feet. The one Ferrari caught is reportedly a wels catfish, which can get up to 15 feet long, making this 8.75-foot long catfish barely above average. We're seeing reports that the biggest wels could be anywhere from more than 300 pounds up to 660. 
  
 Still, it’s not every week you see such big creatures or hear a cool fish tale. CNN reports that (after a flurry of photos to prove it was real) Ferrari released the fish back into the water. The wels catfish can live for decades, though, so maybe we’ll see the same one resurface at a record-breaking size. |||||
In 1991, Steve Feltham said sayonara to his girlfriend, home, and job in England to hunt for the Loch Ness monster in Scotland. His big revelation after 24 years of searching: The beast is probably a catfish—though a big one, obviously. Feltman, 52, has spent much of the last quarter century living in a converted "mobile library" in a carpark near Loch Ness in the hope of catching a glimpse of the alleged creature, report Reuters and the Scotsman. His efforts have now led him to conclude that various sightings of said monster were probably of a Wels catfish. The fish were introduced into the loch in the Victorian era and can grow up to 13 feet long. "I just don't think that Nessie is a prehistoric monster," says Feltham, who holds a Guinness World Record for the longest continuous monster watch on the loch. "What a lot of people have reported seeing would fit in with the description of the catfish with its long curved back." Feltman says his theory explains why Nessie sightings picked up in the 1930s. Of course, the mystery began well before then. In the 6th century, Irish monk St. Columba was said to have exiled a "water beast" to the River Ness. What of the famous 1934 surgeon's photo apparently showing a beast's head sticking out of the water? It actually shows a fake monster head fixed to a toy submarine, as disappointed hunters discovered 60 years later. So does Feltham feel like the last 24 years of his life were wasted? "Never, not for one second," he says. "I'm in my utopia living here on the shores of the loch," he tells Sky News. And he may spend another 10 years probing the case. "I'm not saying the mystery's solved ... I'm still looking for a better explanation." (Read about another secret of Loch Ness.)
