    Some GOOD News !!

    German-born, Port Lincoln fishing baron, Hagen Stehr's success at breeding southern bluefin tuna in captivity has been declared Time magazine's second best invention of 2009.

    The magazine named the 'Clean Seas' breakthrough as second only to NASA's Ares 1 rocket, in its list of the 50 Best Inventions of 2009.

    The Clean Seas' concept of breeding southern bluefin tuna at its Arno Bay hatchery on Eyre Peninsula came in ahead of inventions and innovation, including the AIDS vaccine.

    'At 8.47am on March 12, fish history happened in Port Lincoln, Australia,' the magazine said. 'A tankful of southern bluefin tuna began to spawn, and they didn't stop for more than a month.'

    A delighted Mr Stehr said: 'By coaxing the notoriously fussy southern bluefin to breed in landlocked tanks, Clean Seas may finally have given the future of bluefin aquaculture legs (or at least a tail).'

    'We are excited by its commercial potential and the potential to provide a sustainable source of quality seafood for a protein hungry world - particularly at a time when wild tuna stocks are under threat from over-fishing,' he said. The Commission for the Conservation of Southern Bluefin Tuna last month cut Australia's share of the world quota from 5265 tonnes to 4015 tonnes.

    Clean Seas is due to start commercially breeding southern bluefin tuna by Christmas.

    As long as they are ABSOLUTELY land locked tanks, I think I like this. Scary, tho. Think of the disaster that is salmon farming. I wonder what they are feeding them.

    I agree
    the only way fish farming works is if the tanks are completely isolated from the ocean environment and only if you are not trawling or otherwise degrading the ocean environment in order to feed them. Basically if Tilapia from say the Salton sea would work them feed them those things, they taste like crap anyway and the Tuna would probably love em besides. they die off by the millions every year.

    cheers

    I would put the captain of the Ady Gil in jail.
    I don't like whales hunting, but that kind of manoeuvres breaking the COLREGS are absolutely unacceptable.

    Cheers.

    The more I thought about this link being just a newspaper article, the more I thought this link would be worthless in a couple of weeks, so here is that article:

    It was easy to wake up in the morning, when he first began crossing the world in sailboats 17 years ago, says Derek Hatfield.

    “There was the sound of porpoises and dolphins that had come to play. They were always there in the morning,” said the former RCMP officer, who has just finished third in the Velux 5 Oceans race.

    A round-the-world race – 30,000 nautical miles and 3,000 hours at sea alone – is promoted by marketers as a sailor’s ultimate challenge. But it provided the ultimate shock for the former Canadian sailor of the year.

    The ocean may be vast but not boundless. Hatfield fears that the once-lauded bounty of fish could run out. “The demand for fish is going up but the supply is going down,” he said.

    He saw an estimated thousand fishing boats harvesting fish off Argentina, and more boats whaling in once fish-rich waters off the Grand Banks of Newfoundland.

    “And countries are using ‘scientific research’ as a ploy for killing whales,” said Hatfield. There’d been hundreds of humpback whales when he first went to sea, but the number has dwindled.

    He’s now greeted by silence in the morning instead of dolphin chatter. Hatfield, of Mahone Bay, N.S., looked out over the bow of his 60-foot ECO yacht, day after day, and saw the evidence that between overfishing and pollution, the numbers of dolphins and whales has diminished startlingly. In the past year, he saw no whales and only three dolphins is his last transatlantic crossing.

    “I’ve made 17 or 18 transatlantic crossings and it’s definitely waning,” he said yesterday at the offices of Velux Canada Inc., where he made a debriefing appearance. “I’m not a scientist and I don’t know what happened to them, but it’s definitely reduced from before,” said Hatfield. “I can only assume overfishing and pollution.”

    He said he consumed about 5,000 to 6,000 calories a day – from freeze-dried packets and containers of protein drink – and likened the sailing to training for a marathon 5-6 hours a day. He ‘showered’ using packaged wet napkins.

    Hatfield finished third overall behind American Brad Van Liew and Britain’s Chris Stanmore-Major, but the more important numbers he discovered “were in the **** and pillage of the oceans... There should be more disdain,” he said at the construction engineering company which is making an effort to be environmentally sensitive with specialized windows and doors.

    “My former career was as an RCMP officer, and I was a trained observer. To me, it’s a travesty what’s happening with our oceans. They may look huge, but the world is finite if I can sail around the world in 87 days.”

    Hatfield, 57, is the lone Canadian to twice complete solo circumnavigations of the world. He finished the final leg from Charleston, N.C., to France in fourth spot but was third overall, beating Poland’s Zbigniew Gutkowski to the podium. Hatfield is one of about 125 helmsmen who have made two solo sails around the world.

    “My goal was to have the best Canadian finish going around alone (he did that) but the best moment was getting around Cape Horn (the tip of South America) where I’d been stopped before. For a sailor, it’s like getting to the top of Mt. Everest: there’s still a long way to get down to safety, but this is the place where I’ve got stopped before – capsized or had to put in for repairs at Argentina. It’s treacherous. There’s only 20 to 30 days of good sailing around Cape Horn, and luckily we hit one of them,” Hatfield said.

    He said he will take on the round-the-world challenge again, although he’d prefer to mentor a young Canadian sailor.

    Hatfield sailed in a 60-footer called Spirit of Canada – an Eco Class 60 signed by supporters and sponsored by Active House, which is a consortium of companies involved with Better Living environments – against five solo sailors from Britain, Poland, Australia, Belgium and the United States. The boats relied on wind, electricity and solar energy for fuel

    Bottlemania

    Bottled-water companies haul in $11 billion a year in the U.S., with the help of marketing campaigns that describe the stuff as pristine and natural-that is, better than tap water. Yet 4? percent of the bottled water produced here comes from the same municipal sources as tap, and 85 percent of the 30 to �0 billion plastic water bottles sold end up in landfills. Or consider that shipping one million gallons of "untouched-by-man" Fiji water to New York City dumps 190 tons of carbon dioxide into the atmosphere, nearly 1 0 times as much as the average American produces in 3 year. In Bottlemania, Elizabeth Royte reveals these truths and more, as she examines the evolving debate over who owns water: the corporations that pump millions of gallons from springs and aquifers for pennies, or the locals who see little of the cash but must deal with environmental side effects and sputtering spigots.

    ...and you have to wonder where a LOT of those empty plastic bottles end up :eek:

    Then the thing to do seems to be to convince our elected leaders to ensure that our tap water in our homes is of the highest quality! Drink that instead of the bottled stuff and tell all your friends!

    When I wash the boat in Malaysia I get so thirsty I just stick the hose pipe in my mouth and see how long I can drink the water without spilling any. I can probably take about a gallon before my cheeks blow up and my stomach hurts.

    Its Uk regulated to 60psi and has got fluoride in it. I would'nt drink American water.

    The results, Moore said, “suggest that dolphins are possibly managing bubbles routinely to avoid decompression sickness, also known as the bends. Humans likewise manage 'silent bubbles.’” Only a minority of human divers that get bubbles, he added, get the bends.

    Moore said it was the observation of bubbles in deceased beaked whales that led to the current study. “In routine decompression, the animal exhibits normal physiology and experiences few bubbles,” he said. “But acoustic stressors, such as sonar, seem to change normal bubble management.”

    “Beaked whales are stranding atypically when exposed to sonar,” Moore said. “The beaked whale mortality events have led the current generation of marine mammal physiologists to revisit the question of how marine mammals manage the issue of lung gas being compressed as they dive deeper,” he said. “Above the depth of alveolar collapse, a depth at which the gas-exchange surface of the lung is no longer inflated, increasing pressure with depth can cause gases to dissolve in the body; the gases then come back out of solution as they resurface. If this decompression is uncontrolled, bubbles can form. In humans such bubbles can cause joint pain that is relieved by 'bending' limb joints - hence the popular name. It was thought that marine mammals were immune to such problems, but the beaked whale cases reopened this assumption to fresh scrutiny.”

    That's an odd comment; most of the US has good tap water. I wouldn't hesitate to drink out of the hose anywhere I've ever lived.
