More Than 800 Tons of Fish Die and Rot on Fish Farms South of Philippine Capital

The Government Bureau of Fisheries and Aquatic Resources are still investigating the cause of the fish kill. The damage of the fish, the most in-demand fishes in the country, is estimated at least 50 tons.
More than 800 tons of fish have died and rotted on fish farms in a lake near Taal volcano south of Manila, with authorities blaming it on a sudden temperature drop.

The massive fish deaths started late last week but have eased. Officials have banned the sale of the rotting fish, which are being buried by the truckload in Talisay and four other towns in Batangas province, Bureau of Fisheries and Aquatic Resources official Rose del Mundo said Sunday.

The deaths are unrelated to recent signs of restiveness in Taal volcano, which is surrounded by the lake where many villagers have grown milkfish and tilapia - staple food for many Filipinos, officials said. The volcano and lake are a popular tourist draw.

Talisay agricultural officer Zenaida Mendoza said an initial investigation showed the deaths may have been caused by the temperature change as the rainy season set in last week after a scorching summer, which also depleted the lake's oxygen levels.

Strange He-She Birds Present Gender-Bending Mystery

The unusual cardinal

A strange bird showed up in Larry Ammann's backyard on Jan. 14. Clearly a cardinal, it had the bright red plumage of a male on its left side and gray, female feathers on its right.

"I had no clue how on Earth something like that could happen," said Ammann, a professor of statistics and a wildlife photographer who lives in a suburb of Dallas. "It was a learning experience."

Ammann and the biologists he consulted concluded the bird was most likely part female, part male. Creatures with this condition are called gynandromorphs. They are genetic anomalies: Some cells in their bodies carry the genetic instructions for a male, some for a female. While this gender-bending also occurs among insects, spiders and crustaceans, birds like this cardinal have raised questions about how sex identity is determined among some animals.

As the breeding season began, other cardinals became more territorial, and the bird disappeared before it could be trapped and its feathers collected for genetic testing.

420 Whale Sharks Swarm Mexican Coastline

Up to 420 whale sharks gathered off the coast of the Yucatán Peninsula in Mexico, forming the world's largest known assembly of this species, according to a press release issued by the Smithsonian National Zoological Park.

The discovery counters the widely held belief that whale sharks, which can weigh more than 79,000 pounds, are solitary filter feeders that prefer to be alone in the open ocean. The impressive shark assembly proves they will gather for the right reasons. Food now appears to be the draw.

"Whale sharks are the largest species of fish in the world, yet they mostly feed on the smallest organisms in the ocean, such as zooplankton," Mike Maslanka, biologist at the Smithsonian Conservation Biology Institute and head of the Department of Nutrition Sciences, says in the press release. "Our research revealed that in this case, the hundreds of whale sharks had gathered to feed on dense patches of fish eggs."

Maslanka and his team identified the whale shark assembly using both surface and aerial surveys. Considering these sharks can grow to more than 40 feet long, the surface-level surveying must have been extraordinary.

U.S.: Thousands of Fish Wash up Dead in Ogeechee River

Thousands of fish wash up on Ogeechee River banks, and now people are being warned not to eat from or fish the popular river in five different counties.


"I just ride down here, and I sit and look. I've been doing that for years anyway. I just look at the rivers. Just something to see for me," Nelson Hales said.

Nelson Hales has a sentimental attachment to the Ogeechee River. He's been fishing on the river since he was a little boy and was baptized in the water.

Scotland: Pilot whales leave Loch Carnan following death

Image

A pod of more than 60 pilot whales, at risk of beaching, has again left a Hebridean loch after one of them died.

The animals had left the shallow waters of Loch Carnan in South Uist on Saturday, however returned during the night when the beaching took place.

A post-mortem examination suggested the young female died from a disease, not because it was stranded on rocks.

Another two dolphins were found dead on the beaches in Mamaia and Vama Veche, South East Romania in the last two days, news agency Agerpres reports. According to the executive director of the eco NGO Oceanic Club in Constanta, in the last two weeks the number of dead dolphins was over 15.

According to the director, just last week his organization was signalled regarding the presence of another 7 dead dolphins on the sea shore.

Scotland: Fear For Mass Stranding of Whales on South Uist

Pilot Whales

Marine animal experts are preparing for a potential mass stranding by up to 100 pilot whales in South Uist in the Western Isles.

The whales were spotted in Loch Carnan on Thursday afternoon and about 20 were said to have had cuts to their heads.

It is thought the injuries may have been caused by the whales' attempts to strand themselves on the rocky foreshore of the sea loch.

Sick and injured whales are known to beach themselves to die.

However, at times, dying whales have been followed to shore by healthy animals.

Conservationists have also suggested the whales may have got lost, or entered the loch following prey.

Rescuers said inflatable pontoons for refloating whales were on the way.

The pod had been moving back and forth from the shore and rescuers said the animals were "very vocal", which may be a sign of distress.

The whales, a deep water species, have since moved from the loch back to a nearby bay, where they were seen earlier on Thursday.

Members of the British Divers Marine Life Rescue (BDMLR) fear the whales could die in a massive beaching - which could be Scotland's largest stranding.

BDMLR Scottish organiser Alasdair Jack said preventing the mammals from stranding would cause unnecessary suffering and the animals would only move on to another shoreline.

Not Your Typical Invasive Species

Single-humped dromedary camels were brought to Australia mainly from India in the 19th century. They transported people and equipment in the outback, but when rail and roads came, the camels were let loose, "creating the world's only population of wild camels". It is now estimated that more than 1 million camels are spread over 3.3 million square kilometers (±1.3 million square miles), and they are causing a lot of damage to the local ecosystems.

U.S.: Dead sharks found in Redwood Shores were suffering from internal bleeding, necropsy shows

Officials have completed a necropsy on one of the dozens of leopard sharks found dead in Redwood Shores last month but aren't any closer to pinpointing the cause of the sudden die-off.

The necropsy performed by a California Department of Fish and Game pathologist found "inflammation, bleeding, and lesions in the brain, and hemorrhaging from the skin near vents." Bleeding was also detected around the female shark's internal organs.

Additional tests, such as a bacterial study and microscopic tissue analysis, may provide an answer, according to a statement released by Redwood City. Results could be available by the end of the week.

US: A Stroll on a Gulf Beach Yields a Dolphin Disposal

Image

Laurel Lockamy has seen her share of dead sea life washing up on the beaches of Mississippi. Like a few other residents, she's toted her camera along wherever she goes, documenting the dolphins, sea turtles, red fish and plethora of dead birds that seem to be washing in unusually high numbers.

That isn't stopping Gulf businesses from hoping for a better year than last, when beaches were soaked in oil and tourism vanished with the black tide. Now there are signs business is rebounding. Tourist industries in Florida panhandle report better than expected traffic this year. Some in Congress in fact are pushing for increased drilling in the Gulf, with fewer safety and environmental reviews of the process. It seems some lawmakers have short memories.

But not all is well in the Gulf. High numbers of endangered sea turtles and dolphins have washed into the beaches, although the number of fatalities is declining. Scientists still don't know what has caused this spike in deaths.


Comment: The scientists may claim they don't know what's caused the spike in deaths, but we think it's pretty obvious to everyone else. The BP oil spill is the greatest environmental disaster of its kind in our history. BP dumped two million gallons of toxic oil dispersants in the Gulf, and marine life continues to perish.


Comment: They will never say for sure because they are either paid by BP, or silenced by government agencies.
