The fishermen state that it is the first time that there is massive death of mussels, clams, cúriles and the so-called donkey hooves.

The artisanal fishermen of the coastal communities of the municipalities of La Unión and Conchagua are alarmed at the massive death of mollusks .

The fact, which began about ten days ago and has been increasing, has caused estimated losses of more than $ 25,000 for those who live from the commercialization of these marine products.

This is the first time that a mass death of mollusks has occurred on the coast, said the residents of the Huisquil canton of Conchagua.

Those affected estimate the death of more than one million mollusks scattered over an area of ​​approximately seven kilometers of coasts in the department of La Unión.

The fishermen said that, after the appearance of millions of clams, mussels, curiles and dead donkey hulls, they perceived a strong smell of fuel, in addition to water with mixtures of fat.

Millions of dead shellfish wash up in Waihi Beach, New Zealand

Locals walking on the beach were saddened to find the shellfish on the north end of the beach on Tuesday.
 
The Bay of Plenty Regional Council said in a statement this afternoon the rain last week was the likely caused the pipi to go to higher ground.
 
Staff from the council and University of Waikato collected samples of the shellfish yesterday afternoon and will be analysing these for the presence of toxins. 
 
Samples have also been sent to the Ministry for Primary Industries to rule out any disease cause.
 
The Regional Council funds a Chair in Coastal Science role to provide additional science support for issues like this. 
 
Professor Chris Battershill, the current Chair in Coastal Science, said it is likely a number of factors contributed to this shellfish die-off.
 
“Apart from the weather bomb that hit the area last week, higher ocean temperatures are being recorded in this area and there have been some large sea swells,” he said. 
 
“It is also possible that this is a natural die-off due to stress from overcrowding as there is a very large population of shellfish densely packed just off the beach in this area,” he added.
 
“Although most of the shellfish appeared to be dead we did observe many live shellfish within the wave zone,” Professor Battershill said.
 
The council says it expects to have some results back within three to four weeks.
 
Jeanette McCallum said she was walking with a friend at the northern end of the beach  on Tuesday when they came across the “shocking” sight of the pipi.
 
“We just couldn’t believe it,” she said. “We were crunching on the shells – they were thick, probably about 20cm thick.
 
“It was as far as the eye can see … we were quite shocked and sad.”
 
Most of the pipi have now been washed out to sea by the tide.

Millions of shellfish and other marine creatures wash up on a beach in Hook of Holland, Netherlands

Tussen de massaal aangespoelde tweekleppige schelpdieren werden ook grote aantallen andere soorten zeedieren aangetroffen (foto: Ingrid Mulder)
Saturday 25 July 2015 many people will remember that when in Netherlands stayed still long. A heavy storm with heavy wind pulled over our country and especially the coastal provinces for this storm were the target. A lot of storm damage, and there were several injuries and even a fatal victim to regret. However, this storm for beachcombers with an interest in marine biodiversity a goldmine on. the day after the storm lay the North Sea Beach dotted with innumerable washed up shells and other sea creatures.
 
The day after the exceptional heavy summer storm of Saturday 25 July pulled members of the Dutch Malacological Association (NMV) to the North Sea Beach of Hoek van Holland. Here they went searching for washed up shellfish and other sea creatures that were deposited by the storm on the beach. That beach and then especially the part right next to the breakwater always delivers fun finds on. And after such a severe storm should you expect the number of only larger than normal.
 
What they found, however, exceeded all expectations. It was a huge treasure Chamber with unimaginable numbers washed up shells and other sea creatures. When they approached the beach they saw immediately that there hundreds or potentially thousands of gulls on the beach foerageerden. On the beach arrived they were surprised by the in some places even in mountains of 20 to 30 centimetres high piled shellfish and other marine life. Many of the shells were fresh copies with the meat there are still in. Washed up with the inspection of the material were the screeching gulls briefly at their lunch disturbed.
 
The first thing noticed were the large numbers of American sword schedes (Ensis directus) and Otter shells (Lutraria lutraria). It there were so much not to indicate whether the ten-or certainly hundreds of thousands and perhaps millions of copies were at the American sword sheath. The beach was local completely covered with shells. Between these shells were also massively Halfgeknotte Beach shells (Spisula subtruncata), Clams (Macoma balthica) and white dunschalen (Abra alba). Almost all copies were still alive or contain fresh meat remains.

It is a fact that severe storms cause lots of damage and human suffering. But they also deposit always a real treasure room with lots of fresh and of a great number and many kinds of sea animals on the beach. For lovers and those interested in marine biodiversity is it after a heavy storm, always a pleasure to instantly after a storm the North Sea Beach to wander around looking for beautiful beach finds.

Masses of dead fish and shellfish wash ashore on beaches in Comacchio, Italy

Fish Kill Alert

n the coast the last few hours, Comacchio and Goro days ago, you are seeing a phenomenon that is causing a die-off of fish and shellfish. Technicians are already working.
 
Canolicchi, but also dead fish in riva dei lidi di Pomposa and chess. A similar die-off since days is registering with clams in Goro. It is the phenomenon that is happening on the coast, which Comacchio caused by lack of oxygen in the water.
 
The scorching these days would be warming up the Adriatic Sea, very calm and warm, and anoxia, lack of oxygen, causing mass deaths of fish and clams. There would then pollution. Explain it is Arpa Emilia-Romagna, which monitors the situation.
 
About lidos also tourists and viewers of Telestense have reported die-offs of fish and shellfish, especially razor clams, in addition to blooms of algae that stain red-brown waters. The algae occur mostly in that part of the coast near the Po, then decreased further South.
 
The stranding was due to a lack of oxygen in the water, a ‘ oxygen ‘ crisis caused by the scorching heat of recent days, which resulted in increased water temperature, with peaks above 35 degrees. The calm sea, with the consequent stagnation of water, has helped to aggravate the problem. The phenomenon, already happened in the past, “says harp, not derived from pollutants.
 
It was in fact already happened on the Comacchio beaches in 2013 and now affects especially Pomposa and the Sacca di Goro (in which to be affected are the clams). The harp and the Daphne Institute of Cesenatico are already proceeding to inspections and taking samples constantly monitoring the situation.

Masses of shellfish found dead ‘is a mystery’ on the coast of Ngunguru, New Zealand

A horrible stench set off an investigation into a mysterious mass shellfish death at Ngunguru Sandspit in Northland.
 
Aaron Franklin, who was visiting his parents in the area, alerted authorities to the deaths on Thursday May 21. The engineer estimates there were well over a million dead cockles, tuatua and pipi on the seaward beach and near the mouth of the estuary, with more on the seabed.
 
Franklin returned to the area the next day where representatives from Northland Regional Council were gathering samples. He says the area “reeked of rotting shellfish”.
 
Northland District Health Board is recommending people do not take or consume shellfish from the area until the cause of the deaths is known. Signs advising the public of the incident went up on May 27.
 
Franklin, a member of the grassroots Arctic Methane Emergency Group, says increased levels of carbon dioxide and decreased levels of oxygen in the ocean are one possible cause of the deaths.
 
He says incidences of hypoxia – where oxygen levels drop so low that sealife is killed on mass in a short period of time – have increased rapidly. Ocean currents can cause carbon-dioxide rich water to move to areas with high concentrations of shellfish, where they die as they cannot expel carbon dioxide from their shells, Franklin says.
 
Ministry for Primary Industries (MPI) is leading the investigation into what happened at Ngunguru and says it is testing samples to try and rule out any biosecurity risk. In a statement they say that “investigations like this can require complex testing and it is currently too early to say how long this might take”.
 
A Northland Regional Council spokesman says there is no evidence to back up any particular theory at this stage.
 
“Our guys have to be bound by the science,” he says.

Thousands of TONS of shellfish have died off during past few years in Whangarei Harbour, New Zealand

A massive pipi bed in Whangarei harbour is dying and there are fears the change could destabilise the harbour – and Marsden Point itself, Radio NZ reports.
 
The volume of pipis on Mair Bank has slumped from 10,000 tonnes to less than 100 tonnes, sparking fears the massive sandbank, which protects the harbour entrance, will disappear.
 
The sandbank, shaped similar to a shark’s tooth, lies just off Marsden Point. Locals previously waded out at low tide to scoop up the daily limit of 150 of the shellfish in a couple of minutes. But no more.
 
NIWA fisheries scientist, James Williams, said the decline had been drastic. Over the last four to five years the pipi population has collapsed.
 
He said the bank had been eroding from the south and gaining height; coinciding with an apparent absence of juvenile pipi.
 
“There was a huge biomass there of pipi, everywhere pretty much on the bank and sub-tidally of about 10,000 tonnes and that’s been reduced to less than 100 tonnes from the 2014 survey,” he said.
 
 
“So, less than one per cent of what there was in 2005.”
 
Dr Williams said pollution had not been a problem. Regular testing shows the water quality is very good, despite the presence of the oil refinery and the timber port next door.
 
Mair Bank was closed to pipi pickers last year but Dr Williams said the volume of shellfish being taken, including a commercial catch, was miniscule compared to the vast quantity available.
 
He said it might be worth testing the water to rule out pollution by terpenes — compounds found in pine logs. Dr Williams said it was not known what impact the compounds might have on pipi, but they could act as pesticides on some species.
 
However, Northport chief executive Jon Moore said run-off from the port’s log storage area drained to a big settlement pond.
 
“It can pump to the harbour if it reaches a high level, so if you have a storm event, obviously the last thing you want is all of that overflowing so there’s a pipeline back to the harbour,” he said.
 
“It pumps on those high rain events, but at that point when you’ve got a heavy rainfall, most of the water that’s coming through there is pretty damn clean anyway.”
 
Radio NZ reports the refinery and Northport are worried the loss of millions of shellfish could destabilise Mair Bank.
 
The New Zealand Refining Company’s environmental manager, Riann Elliot, said if the bank goes, there would be knock-on effects for the harbour and the foreshore.
 
He said the channel was “self-dredging”.
 
“There’s no maintenance dredging required here – that could be jeopardised, so the entry to the harbour could be jeopardised.”
 
“Erosion along the foreshore along Marsden Point could change drastically. We’ve currently got a bit of an erosion problem and there’s evidence to suggest that could accelerate.”
 
New Zealand Refining chief executive Sjoerd Post said any increase in erosion had to be a concern for the refinery.
 
“Our site is very close to the sea perimeter, so the pipis dying out may cause instability in the bank which may lead to bigger consequences for us,” said Mr Post.
 
“But first and foremost, we are really concerned around the fact that sort of an entire species seems to be dying out all of a sudden.”
 
Mr Post said it was tangata whenua, Patu Harakeke, who first raised the alarm about the Mair Bank pipi beds.
 
New Zealand Refining and Northport back their call for urgent research into the problem.

Thousands of fish, plus birds, otters and turtles dead due to Kerosene leak in Rome, Italy

A lightning flash, a small electric light dives into the water and fishing. Goes back on the perch, around dozens of fish move their tails on the water surface, bent on one side, with gills that are struggling to find the strength to oxygenate the body. Our skilled fisherman is back there, on the branch, but soon begins to have the first symptoms of intoxication. The plumage is switched off, the kerosene gobbled begins to burn the internal organs: after a while, it falls on the edge of the channel and dies. He was a kingfisher, a small colorful bird that lives in marshy places healthier and is the symbol of an environmental tragedy announced: that of Maccarese . It is the emblem of how there are no guarantees for the environment, for the citizens, for biodiversity, where there insist potentially polluting infrastructure like pipelines national.

We are only a few dozen kilometers north of Rome. Here the Venetians in the 20 reclaimed a vast marshy area, place of migrating birds. Today in this campaign will produce large quantities of fruit and vegetables intended for the markets of central and northern Italy. All around a network of canals that encourages resting, feeding and reproduction of many animals that resemble those territories as places historically dedicated to the journey, moving from Europe to Africa and vice versa. Upstream of this rich agricultural biodiversity and the environment is positioned a pipeline, from 2 meters in diameter, of hydrocarbons traveling for a length of 80 km, from Civitavecchia to Fiumicino . A tube bridge to allow planes of the international airport to fill their tanks of thousands of liters of kerosene.

November 9, there were two incidents, one in Palidoro and one in Maccarese , which caused huge spill of fuel. Probably more than 30,000 liters are finished in rio Three spouts. The alarm party late caused the poisoning of miles of canals that join with the river Arrochar to its mouth. We are in the natural state of the Roman coastline; Nearby complement the ecological corridor three oases in management to WWF. And it was the head of the environmentalist to ask for help to us of Lipu because the situation was precipitated. Volunteers needed immediately for groped to recover and rescue some animals still alive.

We arrived last Sunday: Saturday already were collected corpses of birds and mammals “burned” by kerosene , and we realized the gravity of what happened. Thousands of dead fish, mallards, moorhens, cormorants, herons, otters, turtles, shellfish, even a frog, all dead, impregnated with hydrocarbons. A nauseating smell that we took the head. Volunteers Lipu with courage and passion have followed prior to the north and then south to the main channel leading, after working hours, the dead animals for identification and seizure of ritual. The “angels” of Lipu came from Ostia, Civitavecchia, Rome. There were also experts in the wildlife rescue center Lipu of Rome.

Eni said that he had undergone an attempted theft of kerosene by unknown assailants . For now we have to believe it, but a petition signed by me and the president of the WWF will give more force to the prosecutor’s office which is investigating. Now it is necessary that the reclamation is done in a very short time and that Eni endeavors to damages to the town of Fiumicino to restore the ecological balance that was before the accident. The mayor of Fiumicino , after discontinuing hunting and Fishing in the municipal area and have banned the irrigation of fields with water from the drainage canals, is deploying all its institutional powers to defend his territory and we will be at his side to provide the most appropriate scientific expertise and professional .

Now we wait for the operator of the pipeline complete the removal of the kerosene before the bad weather aggravates the situation. Will start immediately after the claim for damages. In this case I hope that common sense triumphs and to avoid going to the civil court, where we know that a cause can last ten years. But Maccarese needs to start now, we can not wait that long. Meanwhile, today we are still in the field to look for injured animals. Yesterday a mallard and a small otter survived intoxication. A sign of hope for this nature too offended by us men.

Tons of fish, shellfish and birds found dead in lake in Drava National Park, Hungary

alert-now.gif

The incident is just 20-30 with the first discovery of the body count, but now there are more than four tons of fish, shellfish and protected birds died, and estimates there are a lot of dead bodies sink to the bottom.

Environmental Protection Agency, Water Authority, food chain safety bureau, Disaster Management Authority and the Danube – Drava National Park staff several times in the past week extracted from the sample questions lake, although the analysis is still in progress, But experts believe that the reason for this incident but the rain many times in the past few weeks has led to waterlogging and Delaware Canal and how waves (Dombó-csatorna) Multi-level rise occurs, make certain toxic substances into the ponds being.

Somogyudvarhely total of 7.7 hectares belong water Fishing Association, the area is a municipal road is divided into two separate artificial lake, the fish deaths occurred in only where a. Mitigation and relief work currently being carried out by volunteers who work together with, Water Authority and Kaposvar’s “rope associations” volunteers who are trying to save, and Fishing Association has also requested the support of local government. It is understood that the Delaware River and what is yet to come in waves canals contaminated fish died.

The incident did not cause casualties, but more than four tons of animal carcasses classified as dangerous goods to be transported by the Fishing Association is responsible to pay the prescribed places, it will be no small expense. More serious than the loss of material is a direct result of this incident in the past 30 years Fishing Association’s efforts in vain, and the local tourist attraction will be greatly reduced.

The pollution caused by a large number of carp, carp, perch, pike and bream death, many of them for up to one meter, weighing 30-40 kg of fish.

The local government said the size of the problem has more than a small fishing associations and local governments within its power range, so they issued a rescue request to the State Government.
