They found 14 dead dolphins in the coastal party beaches; It’s cetacean species Pontoporia blainvillei, better known as Franciscan or the silver dolphins, at risk of extinction in the South Atlantic. It is the second find in the last 3 months.
The specimens, which arrived to the beaches by the sudestada from last week, were in advanced state of decomposition and therefore may not perform necropsies to learn the causes of death. It is believed that may appear more dolphins killed in the next few days.
Marine World Foundation experts say that these specimens are several days without life at sea and who came to the shore after the sudestada from a week ago, although they do not rule out that they may find more. In addition, warned tourists who are on holiday in the area, in case of finding any animals died, do not approach or touch them, since they can have a high bacterial load and pose a hazard to the health of the people.
It is the second find of these dead animals in the last 90 days in the coastal party; last November, they found 4 Franciscan dolphins in the towns of Santa Teresita, San Bernardo, Mar de Ajó and Las Toninas. Two of them were dead, while the others died after the rescue; one had consumed plastic.
In addition, in February 2016 already had released a copy of this Franciscan species in Santa Teresita; a case that is viralizó through the images of hundreds of tourists photographing with the cetacean that appeared on the shore.
It’s a kind of Dolphin considered vulnerable for the International Union for the conservation of nature; It is one of the smallest in the world and is distributed along the Atlantic coast of South America, especially in the Río de La Plata Southeast. It is the only member of the river dolphin group, but which it does not live exclusively in freshwater, but which does so also in salt water in oceans, and estuaries.
The marine world Foundation works to conserve the species, which in 2003 it was estimated that in the South-West Atlantic they died between 2000 and 3000 a year and could disappear in less than 30 years.

Thousands of blue penguins are dying on New Zealand’s east coast, including in Northland. (Photo / NZ Herald)
Rough seas and strong easterlies – and a successful breeding season – could be behind the deaths of possibly thousands of little blue penguins on Northland’s east coast.
Many east coast beaches have been strewn with bodies of the world’s smallest penguin species, in Maori called korora, along with shearwaters, petrels and other seabirds.
Although the sight has shocked some visitors to the region, even locals used to seeing dead seabirds are concerned at the number of birds in trouble and carcasses, Whangarei birdman Robert Webb said.
The Whangarei Bird Recovery Centre which he manages is caring for dozens of injured or exhausted seabirds brought in this week.
”The birds are copping it for sure in this weather. We’ve been inundated by them,” Mr Webb said.
Yesterday he also dropped off a dozen or so blue penguin carcasses to the Department of Conservation in Whangarei which had been brought into the centre.
While the weather pattern is hammering the east coast, if it were on the west coast the centre would be caring for albatrosses and other big birds, as well as large numbers of penguins and small seabirds, he said.
As for the weak birds, people could help save some by lifting them from the water’s edge if possible and putting them in dunes or grass banks where there was more shelter and they were away from high tide sweeps, Mr Webb said.
”Those that can’t be saved will die anyway. Those with some chance might get a bit of strength back if they’ve got some protection from the elements.”
Other reasons for the deaths included penguins could be in their moult stage — when juvenile feathers are replaced, they are not waterproof and can’t swim. Others could be youngsters whose parents have stopped feeding them, or old ones coming ashore anyway to die, as is usual for penguins.
Graeme Taylor, Department of Conservation’s principal science adviser for marine species, said there’s a strong correlation between El Nino and La Nina seasons and penguin deaths.
In El Nino years, with mainly westerly and southerly winds, seabirds that die at sea tend to wash up on west coast beaches. In La Nina years, with more northerly and easterly winds, seabirds get washed on to east coast beaches in summer and autumn.
”In northern New Zealand, blue penguins breed well in years with El Nino conditions — cooler, well oxygenated and productive seas,” Mr Taylor said.
”We have recently had a big El Nino event and conditions have turned to La Nina this spring and summer with warmer than average seas. The productivity in the ocean has been good, producing lots of penguin chicks.”
It is likely lots of young chicks that left their nests earlier in the summer are now struggling to find food while they learn to fend for themselves at sea, he said.

The total number of olive ridley turtle deaths within just three weeks of its nesting season has reached alarming numbers. Activists tell TNM that 193 dead turtles have been washed ashore as of Friday and the numbers are expected to increase further.
Conservationists who have been monitoring the nesting of the endangered olive ridleys for years now are shocked by the death toll this year. In 2017, the entire nesting season saw 217 deaths. But now, with over three months left for the season to end, the numbers have observers worried.
“Only 24 nests have been sighted by our volunteers so far and if the turtle population goes down, it could have terrible effects on the marine environment. These turtles eat jellyfish that in turn eat fish eggs. So a reduction in turtle population would mean a drop in the fish population as well,” explains Shravan Krishnan of the Students Sea Turtle Conservation Network (SSTCN).
The endangered olive ridley turtles, well-known for their coordinated nesting in large numbers, mostly breed between January and March in southern India. After nesting, the female turtles swim ashore to lay eggs by digging pits in the sand. The hatchlings emerge 45 to 50 days after nesting. The female turtles, however, do not wait to see their eggs hatch and return to the sea.
A forest officer on the condition of anonymity told TNM that one of the main reasons for turtle deaths is the use of gill nets by fishermen.
“The turtles get caught in the net and are suffocated to death. It is the Fisheries department that needs to take immediate action here,” says the officer.
The Fisheries department, however, says it has done its part by banning bottom trawling, purse seine and pair nets.
The department director VP Thandapani told ToI that the government has introduced the turtle excluding device (TED) to ensure turtles are not harmed during fishing.
“When this device is used along with the net, a good portion of the fish that are caught escape through the gap along with the turtles, complain fishermen. So we have asked the Forest department whether it is possible to add a pouch in the device so that the fish can stay, when the turtles escape,” he said.
The director, however, alleges that fishermen have failed to use the device as instructed.
But the city’s fisherfolk claim that the blame for the turtle deaths cannot fall squarely on their shoulders.
“Mechanised boats have hardly gone out into the sea in the last month because the weather is not accommodative. So the Fisheries department needs to stop blaming us,” says K Bharathi, president of the South Indian Fishermen Welfare Association.
“We have complained about the challenges we face with TED several times and nothing has been done about that. There are also other factors, such as degradation of the environment after the oil spill and increasing development work on beaches. The government just finds it easy to blame us,” he adds.

The Christchurch public has been warned to avoid touching dead birds with their bare hands after 300 ducks were found dead due to avian botulism.
The birds may have caught the disease by eating maggots off dead bird carcasses.
Christchurch City Council has issued a warning about the birds and says they will be working to safely remove the carcasses as soon as possible. Avian botulism cannot be transferred to humans.
The council says the toxin which leads to the poisoning, clostridium botulinum, naturally occurs in soils found in ponds and wetlands and it can be harmless until the right environmental factors occur.
The birds, mostly paradise shelducks and some mallards, were found around the Bromley oxidation ponds.
The council says outbreaks of avian botulism are not uncommon worldwide and have occurred in Christchurch previously.
A similar outbreak recently killed at least 50 birds in Te Aroha.

MORE than 100 Sulphur-crested cockatoos have been found dead in Victoria’s north-east, sparking an investigation.
The Department of Environment, Land, Water and Planning says the birds’ bodies were collected by wildlife officers near the Tatong township, close to Benalla, on Thursday.
A number of the birds — from a protected species — will be tested in hopes of determining their cause of death.
The department has also appealed for public information and warned Tatong residents they may come across even more dead birds over the Australia Day long weekend.
“It’s highly likely that the number of birds impacted by this incident will increase over the coming days,” the department’s Greg Chant said. Anyone found to have hunted, taken or destroyed protected wildlife can face “significant penalties”, including jail time, he added.
“Illegally destroying protected native wildlife is a serious environmental crime,” Mr Chant said.
