Scientists are building a three dimensional computer model to test the bite force of the Great White shark using data from a shark caught in beach nets off the NSW Central Coast. The 2.4 metre long Great White shark was stored at the NSW Department of Primary Industries Cronulla Fisheries Research Centre of Excellence until researchers were ready to analyse its jaw and facial muscles.
Marine scientists are offering a reward for the return of a £3,000 shark tag which has been tracked across Scotland's central belt. The device is believed to have come off a basking shark in the Firth of Clyde.
A large 4.5 meters long shark was caught by fishermen in Rizhao, in eastern China's Shandong province on Monday morning, May 7, 2007. The shark measures 2.6 meters round and weighs 630 kilograms.
A shark weighing 113kg has been caught in the North Sea three miles off the coast of Sunderland, UK.
The fish, measuring 2½m, was a large porbeagle shark that is also found in the Mediterranean, Atlantic and South Pacific. It is the biggest such shark caught in the area. It got caught in a trawler’s nets and died. Earlier this week, a swordfish was caught farther up the coast off Northumberland. Rising water temperatures are thought to be behind the discoveries.
Experts have clashed over the existence of Great White Sharks off the UK coast.
Speculation is mounting amid a series of claimed sightings by holidaymakers and fishermen and a new documentary on BBC One on Sunday. Marine biologist Douglas Herdson, from the National Marine Aquarium in Plymouth, rejected claims of sightings. But shark conservationist Richard Peirce says the weight of anecdotal evidence convinces him that Great Whites are in UK waters.
"Temperature and conditions here are all fine, and I'm sure they have been here in the last 3-4,000 years, but they are now so rare it is very unlikely. Shark populations such as blue sharks in the North Atlantic have crashed over the past few years. All the intensive fishing in the Bay of Biscay, catching hundreds of thousands of sharks including one Great White 40 years ago, means I very much doubt they are here now" - Douglas Herdson.
Sharks: Great Whites in Great Britain is showing on BBC One this Sunday at 1900 BST.
