EDMONTON – The discovery of dinner plate-sized goldfish and the ongoing threat of a zebra mussel infestation has the Alberta government ramping up awareness of invasive aquatic species in provincial water bodies.
The zebra mussel, which multiplies prodigiously and can clog water pipes, has been the “poster child” for invasive aquatic species. But seemingly mundane creatures can cause problems, too.
LOS ANGELES — A 4.2-metre-oarfish that washed ashore in Southern California last week was carrying hundreds of thousands of eggs nearly ready to be released.
The serpent-like fish — one of two discovered along the coast last week — was dissected Monday and marine biologists found that the healthy female had 1.8-metre-long ovaries and was ripe to spawn, H.J. Walker of the Scripps Institution of Oceanography said Tuesday.
It wasn’t a tsunami but it had the same effect: A huge cluster of jellyfish forced one of the world’s largest nuclear reactors to shut down — a phenomenon that marine biologists say could become more common.
Operators of the Oskarshamn nuclear plant in southeastern Sweden had to scramble reactor number three on Sunday after tons of jellyfish clogged the pipes that bring in cool water to the plant’s turbines.
Drugs to treat anxiety in people may alter the behaviour of fish when the chemicals are flushed into rivers, according to scientists. Swedish researchers found that European perch exposed to tiny concentrations of a drug became less sociable, ate more and became more adventurous – all changes in behaviour that could have unexpected ecological impacts on fish populations.
WELLINGTON, New Zealand — It was a calm morning in Antarctica’s remote Ross Sea, during the season when the sun never sets, when Capt. John Bennett and his crew hauled up a creature with tentacles like fire hoses and eyes like dinner plates from a mile below the surface.
A colossal squid: 350 kilograms, as long as a minibus and one of the sea’s most elusive species. It had been frozen for eight months until Tuesday, when scientists in New Zealand got a long-anticipated chance to thaw out the animal and inspect it — once they used a forklift to manoeuvre it into a tank.
In a common sense ruling sure to have union advocates howling, a Federal judge says San Bernardino, California eligible for bankruptcy
Judge Meredith Jury of the U.S. Bankruptcy Court for the Central District of California, said the city of 210,000, located 60 miles east of Los Angeles, was eligible for bankruptcy protection "as a matter of law based on incontrovertible facts."
