Farmed Salmon Decimating Wild Salmon Worldwide

The growing global appetite for cheap farmed salmon is imperiling wild fish populations across the planet, scientists warn.

The first worldwide assessment of the impact of cultivated salmon on wild stocks found that where native populations encounter salmon farms, the numbers of wild fish crash, on average, by more than 50 percent.

The farmed fish spread diseases and parasites to wild salmon. Some cultivated escapees also interbreed with the native fish, reducing the ability of their offspring to survive, researchers say.

"The overall trend, over and over again around the world, is that salmon farming seems to have a negative impact on wild salmon," said lead researcher Jennifer Ford of Dalhousie University, in Halifax, Nova Scotia.

'Bizarre' new mammal discovered.

'Bizarre' new mammal discovered.

By Rebecca Morelle

Science reporter, BBC News

A new species of mammal has been discovered in the mountains of Tanzania, scientists report.

The bizarre-looking creature, dubbed Rhynochocyon udzungwensis, is a type of giant elephant shrew, or sengi.

The cat-sized animal, which is reported in the Journal of Zoology, looks like a cross between a miniature antelope and a small anteater.

It has a grey face, a long, flexible snout, a bulky, amber body, a jet-black rump and it stands on spindly legs.

"This is one of the most exciting discoveries of my career," said Galen Rathbun, from the California Academy of Sciences, who helped to confirm the animal was new to science along with an international team of colleagues.

US judge reinstates sonar curbs

Planet EarthA judge has ruled that the US Navy must adhere to a curb on the use of strong sonar in waters off California, amid concerns about its effect on whales.

Judge Florence-Marie Cooper overturned an exemption granted last month by President George W Bush.

He had cited national security when he ordered the Navy's submarine detection exercises should go on.

Conservationists hailed the judge's ruling. It is the latest in a series of disputes over the Navy's use of sonar.

Environmental campaign groups led by the Natural Resources Defense Council (NRCD) say whale strandings and deaths are associated with sonar blasts, which are also thought to damage the brains and ears of marine mammals.

KODIAK -- After a brief vacation to the mainland where they have been fed, bathed, blow-dried and generally pampered, many of the eagles that made pigs of themselves in the back of an Ocean Beauty Seafoods truck filled with two feet of fish guts will spend Valentine's Day back in Kodiak with their mates.

Gary Wheeler, manager of the Kodiak National Wildlife Refuge Visitor Center, said he expects some of the eagles to return within the next couple of weeks to join the other estimated 500 eagles that reside in the city of Kodiak.

In anticipation of their return and release in Kodiak, volunteers at the Bird Treatment and Learning Center in Anchorage are taking the birds outside and getting them acclimated to the cold.

But one of those is unlikely to return to Kodiak.
