70 GIANT stingrays found dead in Mae Klong River, ‘scientists puzzled’, in Thailand

More than 70 giant freshwater stingrays—some of them nearly as large as cars—have been found dead in Thailand’s Mae Klong River over the past few weeks, according to National Geographic explorer Zeb Hogan, who is currently in the country studying the fish.
The die-off is alarming because so few of the river giants remain. Giant freshwater rays are listed as endangered by the International Union for the Conservation of Nature, and scientists say they need to learn more about their populations and biology.
Thai officials are currently studying the dead rays with the goal of figuring out what killed them. They have reported that the river is slightly more acidic than typical around where the dead rays were found, though it’s unclear if that is related yet.
Some Thai environmentalists have suspected a recent spill from an ethanol plant could have poisoned the rays. Others believe they may have been poisoned by cyanide, possibly intended to kill other more desirable fish. (See more photos of megafish.)
Freshwater rays are rarely targeted directly by fishermen because they are not considered good to eat. They are also so large and strong that they tend to break most fishing gear.
A ray recently found alive in the Mae Klong River was 7.9 feet across and 14 feet long and weighed an estimated 700 to 800 pounds, says Hogan, a professor of biology at the University of Nevada, Reno, and the host of the series Monster Fish on Nat Geo Wild.
Even though they’re not hunted, the rays are occasionally entangled and killed as bycatch. They are also threatened by pollution, oil spills, and dams that have fragmented their habitat (read more about the impact of dams in the region in the magazine).
“One thing is clear: a reduction of pollution from surrounding factories is needed to improve the health of the river and save the stingrays in the long term,” Hogan says.
Freshwater megafish, along with freshwater marine mammals, are among the most threatened species in the world, Hogan notes, thanks to pollution, overfishing, and heavy human activity along rivers, from shipping to dams.
“I am hoping that international coverage will encourage more measures to protect this incredible fish,” Hogan adds.

20,000+ cattle dead due to drought in the Chaco, Bolivia

Photographs Ref. Emergency. Producers and authorities worried about the lack of rain that causes the death of animals.
In spite of the rain that fell in the last days in the department, it did not reach all the regions where the drought is increasing sharply increasing the number of cattle. Jose Luis Vaca, president of the Federation of Cattle Ranchers of Santa Cruz (Fegazacruz), said according to the latest report that dead cattle amounted to more than 20 thousand, overcoming an economic loss of $ 8 million in the Chaco alone. “A few months ago the mortality of animals had not exceeded 5,000 in Santa Cruz, but as the deaths are increasing, they are much larger, we have a general data of the whole Chaco that is 20 thousand heads already dead, alone In the zone of Macharetí that corresponds to Chaco chuquisaqueño have died more than 10 animals, in the Chaco cruceño 9 thousand and in the Valleys are about 1,800 cattle, said Vaca
It does not rain in the Chaco. The president of Fegasacruz, said that in the Chaco has not rained for a long time and the drought is much harder. “Because it rains in the city and in some parts of the department, some people think that the water came to the Chaco but the reality is different,” he said, adding that the government is helping to help the producers who They need it most. On the other hand, he questioned the Government because the budget allocation committed in one of the decrees had not been reached.
The Valleys are also affected. Hernando Becerra, mayor of Saipina, said that the lack of water due to drought, caused the loss of at least 800 hectares of crops, the death of more than 100 cattle and 500 that are at risk, to this is added that The dam that provides the liquid element for irrigation is about to dry completely due to obstructions in the access roads.
The Government commits aid. Reymi Ferreira, Minister of Civil Defense, said that humanitarian assistance has been coordinated with the mayors of Comarapa and Saipina, respectively, so that next week they will receive food, water and later the seed will be made. “In the case of Saipina if it does not unlock the pipes that are blocked that dam that cost several million dollars will be unusable affecting a population that lives from agriculture and livestock,” said Ferreira.

Hundreds of dead fish washing up along a lake in Chennai, India

Fish Kill Alert
The Madipakkam lake, one of the few remaining large water bodies in the city, appears to be fast turning into   a graveyard for the fish it breeds.
For the past three days, hundreds of dead fish are being found on the shores of the lake due to depleting oxygen levels.
Krishna Kumar, a local resident, said he had seen the lake shrink over the years. The water body could well be Chennai’s ‘Vedanthangal’- a delight for bird watchers.
The tag which he gives to the lake, spread over 20 acres, is appropriate as numerous water birds, including spot-billed pelicans, can be seen throughout the day. “Besides birds, there were countless fish, but not anymore. The fish are dying thereby threatening the ecosystem. This shows the lake is in urgent need of rejuvenation,” he said.
It all began when residents of Ayyapa Nagar bordering the lake complained to the local civic authorities on Wednesday about fish dying in the lake. Corporation officials cleared the dead fish the next day. Five teams, each comprising two persons, were deputed for the task. Furthermore, acting in tandem with the fisheries department, health and sanitary officials of the corporation (ward 187) found that oxygen in the lake was well below the required level.  
Using the dissolved oxygen meter, they found that the oxygen level in the lake had dropped to three mg/L, when it should have been at least seven mg/L.
In certain areas of the lake, the oxygen level decreased to as low as one mg/L, which officials say explains the death of fish.
Another resident, T V Ramakrishnan, who had been living nearby for the past 28 years, said he had not seen any periodic maintenance work at the lake. “The smell of dead fish has permeated the locality. I have never seen this (dead fish) on such a large-scale in the past,” he said.
As an immediate measure, dissolvable oxygen granules were procured. “A boat was hired, using which the granules, weighing 10 kg, were sprinkled on the lake’s surface. This has helped partially improve the oxygen level so that the situation doesn’t turn worse,” S Ramaiah, health and sanitary inspector told Express.
He explained that the present situation was due to decreasing water quantity, diminishing oxygen levels and breeding of fish uncontrollably.
There as six inlet pipelines to the lake, which convey  domestic untreated waste water to the lake – no longer a drinking water source that it used
to be.
“There is a proposal on our side to construct a tank which would treat this inflow of waste water. However, it is the Public Works Department, that is responsible for maintaining the lake,” the official said.

Tens of thousands of birds being killed due to avian flu outbreak throughout Europe

Bird Flu
The H5N8 virus has also been found in Hungary, Poland, the Netherlands, Denmark and Croatia.
Germany, Switzerland and Austria reported new outbreaks of a severe strain of bird flu on Saturday in the latest in a series of cases across Europe.
The H5N8 virus has also been found in Hungary, Poland, the Netherlands, Denmark and Croatia.
In Germany, the state of Schleswig-Holstein reported one case of bird flu confirmed at a farm where 30,000 chickens would now be culled. The state’s agriculture ministry said an area of 3 square km (1.2 square miles) had been sealed off.
In Berlin, the federal agriculture minister, Christian Schmidt, said the government had set up a crisis management desk.
The Austrian Agency for Health and Food Safety confirmed a second outbreak at a chicken farm in its western Vorarlberg province close to the German and Swiss borders and said 4,000 would be culled.
An Austrian poultry farm close to the chicken farm had tested positive for H5N8 on Friday.
A protection zone with a radius of at least 3 km and a surveillance zone with a radius of at least 10 km around the infected holdings will be created to keep migrating birds from transmitting the disease to farm poultry.
Bird flu was also confirmed in dead birds along Lake Geneva in Switzerland on Saturday.
Austria and Switzerland earlier this week took steps to prevent the spread of the virus to domestic poultry after discovering the disease in wild ducks around Lake Constance.

Masses of wild salmon turning up dead, ‘a mystery’, along the Cedar River, USA

More sockeye salmon are dying before they spawn this year, and scientist want to know why.
Biologists with West Fork Environmental collect sockeye carcasses as they cover more than 20 miles of salmon habitat in the Cedar River each week.
So far this season, they’ve picked up 1,600 dead fish. They mark the GPS location of each carcass and tag the fish. This year, they’ve found more sockeye dying before they ever spawn.
“That’s been one of the biggest Eureka’s and surprises, but it’s not a good one, because there’s mystery around this disease or suite of diseases, and then problems with what we can do to counteract it,” Michelle Koehler, who works with Seattle Public Utilities on the carcass survey.
The heads of the salmon are dissected for the otolith, which is a piece of the inner ear that tells scientists whether the fish are hatchery or wild sockeye. It also tells age and provides clues about environmental conditions during the sockeye’s lifetime.
Scientists want to know how hatchery sockeye affect wild salmon. The collection also shows whether the hatchery fish are spawning around all parts of the river.
“That’s what these scientists have actually been able to verify,” said Michelle Koehler, who works with Seattle Public Utilities on the carcass survey.
The disease that is killing the salmon is likely caused by a parasite, but it could be more common with warming water temperatures. There is no human health risk associated with the disease, according to West Fork Environmental.

Thousands of dead fish found floating in a river in Norrkoping Sweden

Fish Kill Alert
The dead fish were discovered during the morning.
It is both salmon and walleye, pikeperch. We are looking at what caused it, and the fish will also be picked up by a contractor, says Louise Flygt, communications director at the municipality of Norrköping.
Pisces flows mainly between Iron Bridge and the area at Strömsholmen, reports
Norrkoping investigating the cause of fish death
The municipality is now investigating the cause of the incident.
We identify if there was no release, calling around to different agencies to gather information and will possibly take water, says Isabelle Brobeck, the environmental and health protection, told the newspaper.
“May have knockats”
According to the newspaper Gustav Palmkvist, a municipal, received information about the major changes in water level.
One theory could be that many fish stood upstream when the water released in full, which meant that they swept in and knockats of power. But it is still only speculation, he told the newspaper.
Neither the emergency services or the police in Norrköping say they have no information about the incident.

Hundreds of dead fish washing up on beaches of Reunion Island

Fish Kill Alert
Several hundred fish found dead in the lagoon: at the Ermitage, Trou d’Eau, Saint-Leu … 
At Trou d’Eau, at the Hermitage and at Saint-Leu this Wednesday morning, it is a spectacle of desolation on the beaches. Indeed, several hundred reef fish lie on the sand. 
Decimated Reef Fish 
It was in the commune of Saint-Leu that the first observations of dead fish were made, as of Tuesday, at around 14 hours. 
At the Hermitage, they are mostly reef / coral fish, which have been found: young ladies, balistes or canthigasters. 
As a precaution, the Marine Reserve teams invite the swimmers to get out of the water. 
A death that remains mysterious at the moment 
For now, the origin of these dead fish remains mysterious. At least two hypotheses would be advanced: either the track of a bacterium in the water, or a tide abnormally low the day before this discovery. The algae present in the lagoon will then consume oxygen in the remaining little water and can result in the death of the fish. 
A similar situation had occurred in 2014 
The last episode of mass death of marine fish dates back to 2014 in the west and south of the island. 
The prefecture advises not to touch the fish naked and not to consume them. In Saint-Leu, nautical activities are prohibited from the beach from the city center to the northern part of the coast until further notice.

Hundreds of Puffin birds washing up dead, ‘scientists alarmed’ on Pribilof Islands, Alaska, USA

The tufted puffins started washing ashore on St. Paul Island in mid-October—first a handful, then dozens, then so many that volunteers patrolling to collect dead birds began walking their four-wheelers rather than riding. It was easier than getting off every few feet.
The hundreds of dead, emaciated puffins showing up on this isolated, wind-swept scratch of land in the Pribilof Islands in the middle of the North Pacific suddenly has scientists worried—about the population of this white-masked, orange-beaked seabird, but also about what their deaths may portend for the normally productive Bering Sea.
A stretch of water that provides more seafood than any other in North America saw such record-warm temperatures earlier this year that scientists suspect the ocean food web there has shifted. That could spell big downturns for marine life, from seabirds and fur seals to salmon, crab and the $1 billion-a-year pollock fishing industry that provides flaky white filets for everything from McDonald’s fish sandwiches to frozen fish sticks.

55 TONS of dead fish have been removed from Longboat Key canals, Florida, USA

Fish Kill Alert
As in 55 tons of dead fish removed through Thursday from 91 canals and the shorelines surrounding the island, according to Mark Richardson, Longboat Key streets, facilities, parks and recreation manager.
Longboat Key started sending tons of dead fish to the landfill in September. Town Manager David Bullock said 16 more canals were cleaned Wednesday.
“This event just hasn’t ended,” said Bullock. “And it’s intermittent. It keeps coming back in.”
The Florida Wildlife Commission reported Wednesday the red tide presence is not gone entirely in Sarasota and Manatee counties. FWC reported low to medium concentrations of red tide in nine Manatee County samples and very low to high concentrations in 33 Sarasota County samples.
Red tide involves a higher than normal concentration of microscopic alga. In Florida, red tide is usually caused by the species Karenia brevis. It can be toxic to fish and water mammals and cause severe respiratory issues in humans.
