India: Experts Clueless After ‘Alarming Number’ of Marine Deaths Off Konkan Coast

04/08/2012 Leave a comment

By Aakriti Vasudeva, The Indian Express – “The alarming number of marine deaths off the Konkan coast in the past few days, with two whales and several turtles found beached in separate incidents, could be natural or fishing-related, said experts.

A 35-foot whale identified as a Baleen whale was found beached at Priyadarshini Park at Napean Sea Road on Saturday. A similar whale was found dead at Uran on Thursday. Both were found in a highly decomposed state. There were unconfirmed reports of a third whale being beached off the Raigad coast on Monday. Meanwhile, many turtle deaths were reported over the last few days from the Raigad coast with 11 turtles found dead on the Shrivardhan coast on Saturday.

‘We have got queries from Mantralay and Fisheries department and have been trying to find out the cause of the whale deaths for the past two days, but have been unable to do so. We are studying the migrational routes of the whales along the Indian coast and gathering information on it,’ said Dr Vinay Deshmukh, principal scientist, Central Marine Fisheries Research Institute…

In case of the turtle deaths, the Roha forest department said about 24 dead turtles were found in a badly decomposed state from the Murud and Shrivardhan coast in the last month. 11 turtles were found dead at Shrivardhan on Sunday. ‘The vet we consulted said the turtles died of natural causes, but investigations are on ,’ said Deputy Conservator of Forests (Roha) Sarfaraz Khan.” Read more.

Gulf of Mexico: Thousands of Dolphins Dying in Massive Die-Off, Symptoms Consistent With Those Seen in Animals Exposed to Oil

04/08/2012 1 comment

By Tim Wall, Discovery News – “The dolphins in the Gulf of Mexico are in the midst of a massive die-off. The reasons why remain a complicated and mysterious mix of oil, bacteria and the unknown.

Normally an average of 74 dolphins are stranded on the northern shore of the Gulf of Mexico each year, especially during the spring birthing season. But between February 2010 and April 1, 2012, 714 dolphins and other cetaceans have been reported as washed up on the coast from the Louisiana/Texas border through Franklin County, Fla., reported the National Oceanic and Atmospheric Administration. Ninety-five percent of the mammals were dead.

Since many of the dead dolphins sink, decompose or are eaten by scavengers before washing up, NOAA believes that 714 may represent only a fraction of the actual death count. NOAA declared the die-off an ‘Unusual Mortality Event’ as per the Marine Mammal Protection Act of 1972.

Although the timing of the die-off largely coincides with BP’s Deepwater Horizon oil spill and its aftermath, the deaths actually started increasing about two months before the April 20, 2010, explosion, which started the monthslong oil spill.

Before the spill, 112 dolphins had already been reported stranded on the shore.

In the summer of 2011, NOAA tested 32 live dolphins in Barataria Bay, an area heavily impacted by the oil spill. The dolphins were underweight, anemic, and had low blood sugar and/or some symptoms of liver and lung disease. Nearly half had abnormally low levels of hormones that help with stress response, metabolism and immune function.

The symptoms are consistent with those seen in animals exposed to oil.” Read more.

Peru: Hundreds of Dead Dolphins Counted Along 90-Mile Stretch of Peru Beaches, Number of Dead Will Reach Into the Thousands

04/08/2012 Leave a comment

By Miguel Llanos, MSNBC – “Conservationists counted 615 dead dolphins along a 90-mile stretch of beaches in Peru, a wildlife group said Wednesday, and the leading suspect is acoustic testing offshore by oil companies.

‘If you can count 615 dead dolphins, you can be sure there are a great many more out at sea and the total will reach into the thousands,’ Hardy Jones, head of the conservation group BlueVoice.org, said in a statement after he and an expert with ORCA Peru walked the beaches.

Indeed, the head of a local fishermen’s association told Peru21.pe that he estimated more than 3,000 dolphins had died so far this year, based on what he saw in the water and on beaches.

BlueVoice.org stated that ‘initial tests … show evidence of acoustical impact from sonic blasts used in exploration for oil.’

The ORCA Peru expert, veterinarian Carlos Yaipen Llanos, said that while ‘we have no definitive evidence,’ he suspects acoustic testing created a ‘marine bubble’ — in essence a sonic blast that led to internal bleeding, loss of equilibrium and disorientation.

Another possibility is that the dolphins suffered from a disease outbreak, Yaipen Llanos said.” Read more.

Australia: Experts Investigate Death of Scores of Catfash Found in Boyne River

04/08/2012 Leave a comment

By Stephanie Fitzpatrick, ABC News – “The State Government is investigating the death of scores of catfish found in the Boyne River, south of Gladstone in central Queensland.

Staff from Queensland’s Department of Environment and Heritage Protection (DEHP) have been inspecting more than 100 dead catfish found at the mouth of the Boyne River earlier this week.

The cause of death is unknown.

Tannum Sands resident John Mikkelson says he has seen dozens of the fish washing up in the past week.

‘Some of the ones I’ve seen are very emaciated and have white ulceration on the sides, yet others appear quite healthy,’ he said.

Local seafood processor Ted Whittingham says he has counted almost 200 dead catfish near the river in the past few days.” Read more.

Texas: Hundreds of Fish Found Dead in Lake Hollow of Fort Worth’s Meadowbrook Hills

04/08/2012 Leave a comment

By Andrew Tanielian – “Frustrated homeowners in Fort Worth’s Meadowbrook hills are wondering what’s killing hundreds of fish in their backyard pond.

Neighbors started to notice the dead fish after Tuesday’s storms.

The pond known as Lake Hollow was once a relaxing escape for Michael Anderson and other homeowners who live in Meadowbrook Hills.

‘And we just sit down in the evenings on the landing and just revel in the beauty,’ said Anderson.

An unknown problem is bringing the anxiety of a wasteland.

‘Obviously this lake is going to turn into a health hazard the way things are going,’ said Anderson.

Hundreds of dead fish including perch and catfish floated to the top of the pond.

Neighbors immediately called the city for help.

Workers ruled out a sewage leak and are investigating what else could have caused this including testing water samples.” Read more.

Malaysia: Fishermen Worried After Unprecedented Fish Kill Litters River With Thousands of Mullets, Cat Fish and Other Species

04/08/2012 Leave a comment

“THE Department of Environment will investigate the cause behind the deaths of thousands of fishes at Parit Jawa here recently.

A team of officers will be sent to the fishing village to collect water and dead fish samples to ascertain what killed them.

Johor DOE director Mokthar Abd Majid said one of the possible causes was the lack of oxygen in the water due the changing tides.

‘Of course, water pollution is another possibility.

‘Until we examine the water and fish samples, we cannot tell what could have killed the fishes,’ he told Streets yesterday.

Among the thousands of dead fishes seen along the 130-metre long Parit Jawa were ikan belanak (mullet), senangin (thread fish), gelama (jew fish) and belukang (cat fish). Most of the dead fishes were ikan belanak.

Parit Jawa is a fishing village which is also famous for its asam pedas fish.

It is learnt that fishermen who were about to go to the sea at 4am spotted the dead fishes in the waterway.

This is the first time that such a huge number of fishes were found dead.

Within six hours, most of the dead fishes had drifted to the sea at high tide.

Azman Abdul Rahman, 54, a fisherman, said he found the fishes when he went to his boat at the river at 4am.

‘The river was literally littered with dead fishes, the first time I witnessed since I became a fisherman 40 years ago.'” Read more.

Alaska: Polar Bears Show Signs of Mysterious Illness

04/08/2012 Leave a comment

By Annie Feidt – “Biologists have found Polar Bears in the Beaufort Sea with hair loss and skin lesions. Those are the same symptoms that have sickened ice seals and walruses in the arctic since last summer and led the federal government to declare the incident an unusual mortality event. Scientists are just beginning an investigation into whether polar bears are suffering from the same thing.

“The first day we observed it was on March 21st and we had three captures and two of them had Alopecia, which is the skin loss and so it was like, ‘oh that’s interesting.’ Then we started picking it up on other animals in later march so it was like, this is more than normal.”

So far, the field scientists have found hair loss on nine of the 33 bears they’ve captured. The bears have skin lesions on their head, neck and ears. Degange says they have found polar bears with similar symptoms since 1999, but the number of effected bears makes this year unusual:

“The bears appear to be healthy otherwise. We haven’t seen any dead bears, so its not a mortality event as far as we know. But the fact that its occurring at the same time as this unexplained mortality event with seals certainly raises the interest level.”

The biologists collected blood and tissues from the affected bears to try to figure out if the symptoms are related to the mysterious illness that has been found in ice seals and walruses. Dozens of seals have died from the disease, but no walrus deaths are attributed to it. Scientists don’t know yet if the walrus and seals are suffering from the same thing. Although the veterinary pathologist who has done most of the necropsies on the animals say the lesions look very similar under the microscope. Julie Speegle is a spokesperson for the National Marine Fisheries Service. She says its been a difficult case:” Read more.

Minnesota: Thousands of Fish Found Dead Along Pelican River Near Orr

03/20/2012 Leave a comment

By Sam Cook – “Thousands of fish, including many game fish, have died in a fish kill on the Pelican River near Orr, said Kevin Peterson, Department of Natural Resources area fisheries supervisor at International Falls.

‘It was a substantial fish kill. It’s an unfortunate loss of our fisheries resource,’ Peterson said.

The kill, probably caused by low oxygen levels in the water, occurred in an approximately 2-mile stretch of the Pelican River from the dam at St. Louis County Highway 23 and downstream past U.S. Highway 53, Peterson said. The fish kill was first reported Thursday, March 15, Peterson said. A fisheries crew visited the site Monday and traveled the river by canoe to assess the extent of the kill.

‘They saw a lot of northern pike, one smallmouth bass, lots and lots and lots of black crappies – probably thousands from 3 inches and up,’ Peterson said. ‘They saw some larger bluegills up to 10 inches, lots of yellow perch and bullheads and suckers.’

Tom Burri, assistant area fisheries supervisor at International Falls, was part of the crew that checked out the kill.

‘Definitely, there were thousands of crappies and hundreds and hundreds of pike,’ Burri said.” Read more.

Singapore: Thousands of Dead Fish Seen Near Pasir Ris Park

03/20/2012 Leave a comment

“Thousands of small dead fish were found today along Sungei Api Api, which flows along an HDB estate and Pasir Ris Park.

Thousands more were also found along the banks of Pasir Ris Beach, reported The Straits Times.

National water agency PUB said the marine fish seems to have been washed in at the tide. According to the paper, it found out about the incident this morning.

Workers have already started cleaning up, and were seen scooping up the dead fish into black plastic bags for disposal.

The incident has no impact on Singapore’s drinking water, said a PUB spokesman, as the river is not part of Singapore’s drinking water supply.

The cause of the incident is being investigated by the NEA.” Source – Asia One News.

Canada: Over 400 Grey Seals Found Dead Off Cape Breton Coast, Baffled Officials Claim ‘No Reason For Alarm’

03/07/2012 Leave a comment

By Chris Shannon – “SYDNEY — The discovery of more than 400 dead grey seals off Cape Breton’s eastern coastline is no reason for alarm, the Department of Fisheries and Oceans said Sunday.

The seal carcasses, some without eyes from scavenging seagulls and other wildlife, are on the beaches of Hay Island, a short distance from Scatarie Island.

Federal fisheries department seal biologist Mike Hammill said the mammals showed no sign of physical trauma other than the wounds inflicted by predators after death.

‘They weren’t killed by people, so it’s something else that’s come along,’ he said from Charlottetown following a tour of the island Sunday.

‘The majority of them are weaned pups and they look in fairly good shape. They’re fat, didn’t seem to have any external markings on them.’

Parts of the seals were taken for testing to the Atlantic Veterinary College in Charlottetown. Hammill said it could be weeks before a possible cause of death is identified.

The group of DFO scientists counted about 100 to 200 live adults and about a dozen juvenile seals.

Hammill confirmed the approximate number of dead seals that was initially reported by Humane Society International/Canada on Friday.

In a release, the group’s executive director Rebecca Aldworth said she hadn’t seen ‘this kind of mortality’ in apparently healthy grey seals in her five trips to the island’s seal colony.” Read more.

Tennessee: Mysterious Horse and Cattle Deaths Baffle Detectives in Maury County

02/27/2012 Leave a comment

By Nick Beres – “MAURY COUNTY, Tenn. — Horses are dying and now cattle as well and detectives in Maury County have been at a loss to explain how or why it is happening.

First, seven seemingly healthy horses turned up dead last week at a Hampshire farm in Maury County. The state performed a necropsy and released the results.

‘They ruled that it’s undetermined. The cause of death cannot be determined at this time. It is a mystery. We don’t know what happened,’ said Detective Terry Chandler with the Maury County Sheriff’s Department.

Now Detective Chandler is investigating more deaths: Two dead cows at a farm across from the one where the seven horses were found. And he’s consulting with police looking into more mysterious horse deaths in Dickson and Giles county.

Chandler said there is no evidence anyone is intentionally harming the animals.

He said they have not ruled out the possibility the livestock died from eating contaminated hay or a poison plant. It’s possible the toxins were not detected by the state testing.” Source – NewsChannel5.com.

UK: Mystery Virus Killing Thousands of Lambs, Survival of Many British Farms Threatened

02/25/2012 Leave a comment

By Cole Moreton – “The Schmallenberg virus causes lambs to be born dead or with serious deformities such as fused limbs and twisted necks, which mean they cannot survive.

Scientists are urgently trying to find out how the disease, which also affects cattle, spreads and how to fight it, as the number of farms affected increases by the day.

So far, 74 farms across southern and eastern England have been hit by the virus, which arrived in this country in January.

A thousand farms in Europe have reported cases since the first signs of the virus were seen in the German town of Schmallenberg last summer.

The National Farmers Union has called it a potential ‘catastrophe’ and warned farmers to be vigilant. ‘This is a ticking time bomb,’ said Alastair Mackintosh, of the NFU. ‘We don’t yet know the extent of the disease. We only find out the damage when sheep and cows give birth, and by then it’s too late.’

It is unclear exactly how the disease arrived in Britain, but the leading theory is that midges carried the virus across the Channel or North Sea in the autumn. However, scientists cannot yet rule out transmission of the disease from animal to animal.

Infected ewes do not show any symptoms of the virus until they give birth, with horrific results. Farmers have described delivering the deformed and stillborn animals as heartbreaking.

The lambing season has only just begun, which means that the full impact of the disease will not be felt until the weather warms up and millions more animals are born.” Read more.
