No place like home: New theory for how salmon, sea turtles find their birthplace
How marine animals find their way back to their birthplace to reproduce after migrating across thousands of miles of open ocean has mystified scientists for more than a century. But marine biologists at the University of North Carolina at Chapel Hill think they might finally have unraveled the secret.  12/2/08

Parachuting allows krill to eat and run
Cell Press | EurekAlert!
Antarctic researchers have recorded a novel behavior in krill that may help regulate greenhouse gases. Antarctic krill, one of the largest animal resources on Earth, parachute into the deeper layers of the ocean many times a night and sequester large amounts of carbon in the process. 2/5/2006

'Biobullets' fight harmful mussels
American Chemical Society | EurekAlert!
British researchers have developed a "biobullet" that could help control an invasive mollusk that has ravaged U.S. waterways for nearly two decades. The microcapsules, which contain toxins that dissolve within a zebra mussel's digestive tract, offer a safe and cost-effective way of eliminating one of the world's "most important economic pests" without harming other aquatic life, according to a report in the Feb. 1 issue of the American Chemical Society's Environmental Science & Technology journal. 1/30/2006

Flap over fishes: Who's the smallest of them all?
University of Washington | EurekAlert!
The authors of a paper in this week's Proceedings of the Royal Society of London Section B, who say their 7.9 mm-long fish from a peat swamp in Southeast Asia is the smallest fish and vertebrate known, have failed to make note of work published last fall that describes sexually mature, male anglerfishes measuring 6.2 mm to 7.4 mm in length. 1/29/2006

Scientists find 'smallest fish'
Roland Pease | BBC News
Scientists discover the smallest fish on record in the peat swamps of the Indonesian island of Sumatra. 

Individuals of the Paedocypris genus can be just 7.9mm long at maturity, scientists write in a journal published by the UK's Royal Society.
But they warn long-term prospects for the fish are poor, because of rapid destruction of Indonesian peat swamps.

El Salvador studies mystery deaths of rare turtles
Reuters
SAN SALVADOR, El Salvador (Reuters) - More than 100 rare sea turtles have washed up dead on Pacific beaches in El Salvador this month, and scientists said on Monday they were struggling for an explanation.
A total of 119 dead turtles have been found at different points along El Salvador's coast since the start of the year. The turtles belong to the Olive Ridley, Hawksbill and Green turtle species.
"The final cause is still unknown," said Claudia Vega, a veterinarian with the El Salvador Zoological Foundation.

Lobsters Use Smell Test to ID Buddies, Bullies
John Roach | National Geographic News
Jelle Atema says when he first encountered lobsters as a young marine biologist in the 1970s, he was surprised at how peaceful the giant-clawed crustaceans behaved toward each other.
"I'd swim around and see lobsters meet each other, give a display, raise their claws. But there was not much fighting," the professor at Boston University's Marine Program in Woods Hole, Massachusetts, said. Now he understands that those lobsters already knew each other. A few swishes of their small antennae were all they needed to pick up the other's scent and recall their earlier battle that established who was dominant.

'Darwinian debt' may explain why fish stocks don't recover
Blackwell Publishing Ltd. | EurekAlert!
Why does it take so long for fish stocks to recover from over-fishing? This problem has been worrying both scientists and fishery managers who expect stocks to quickly rebound when fishing stops. Now published in Ecology Letters, a research team from Stony Brook University believes they have an answer: continually harvesting the largest and oldest fish (as fishing regulations typically require) alters not only size but also numerous other genetic characteristics that are harmful to the overall population. 1/10/2006

Fish flock to Christmas tree reefs in US lakes
Reuters
Stripped of tinsel and ornaments, thousands of Christmas trees across the United States are becoming reefs for fish in fresh-water lakes.
The U.S. Army Corps of Engineers collects discarded trees to create an underwater forest near fishing piers in man-made lakes that lack natural habitats.
"The little fish will go in there for cover and to feed and the big fish will follow them," said Eric Lemons, a park ranger at Wappapello Lake in southeast Missouri, which gets about 200 Christmas trees a year.   1/6/2006
