Up to 20 dead stingrays found on a beach in Dubai, United Arab Emirates

17.12.18 Dead Stingrays In Dubai

One of the stingrays found on Monday morning at Sunset Beach in Dubai. The animals were believed to have been caught up in illegal fishing nets.

Up to 20 stingrays have been found dead on a beach in Dubai.

Marine experts called to the scene at Sunset Beach on Monday said the fish were most likely dumped by fishermen who were after a different species.

Beachgoers discovered the adult and baby rays, some of which were still alive, while on their early morning walks.

Many of the fish had marks on their necks suggesting they may have been caught in nets prior to being dumped.

Natalie Banks, managing director of Dubai-based marine conservation organisation Azraq, said she spoke to people near the beach beside the Burj Al Arab.

“They told me that this has been going on for years and the authorities need to take action,” said Ms Banks.

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.

Dozens of Stingrays found dead, ‘very rare phenomenon’ on a beach in Vitoria, Brazil

Nobody knows for sure what were the causes of the fact. According to the Director of the Orca, Lupércio Aguilar, one of the possible causes can be a mass stranding
Dozens of stingrays were found dead on the edge of Camburi Beach in Victoria, on Tuesday morning (21). The Civil Police should investigate the fact to know if the reason of dead animals was natural or criminal order.
 
Nobody knows for sure what were the causes of the fact. According to the Director of the Orca, Lupércio Aguilar, one of the possible causes can be a mass stranding.
 
“As far as I can see this is a very rare phenomenon. I think a mass stranding of Manta Rays, whales and dolphins. With stingrays, the phenomenon is very rare and you only get news from a hit in Israel, in 2003, “says Aguilar.
 
Lupércio does not believe in the possibility of foul play. “I don’t think it was a crime, because the rays are worth money, and if they were handles in fishing nets they wouldn’t leave it like this, especially with that number so big”, he adds.
 
From the screenshots, it is not possible to have a certainty about what is the species of the animal, but it is believed that the animals are stingrays-nail (Dasyatis Americana), common species in the Bay of the Holy Spirit.
 
For oceanographer Bruno Berger rabbit, however, the motive of the animals can be an illegal practice commonly committed by fishermen at night in Cambridge.

“What happens is something very serious, are fishing trawlers from Cameroon, which is illegal, that’s been going on forever in Cambridge. On many nights this happens and we always informs the police and also with the municipality, for at least the fact, “he says.
 
In a statement, the Environmental military police (PMA) reported that a team will place this Tuesday (21) to verify the situation and report the facts in a case that will be presented at the station of Environmental Crimes, so that the Civil Police investigate the case.
 
The note stresses that environmental crimes are monitored in partnership between the environmental police with the municipal environmental agencies, in addition to the Instituto Estadual de Meio Ambiente e Recursos Hídricos (Iema) and the Institute of Agricultural and forest Defense of the Holy Spirit (Idaf).
 
Also note, the Iema reported that also sent a team to investigate the complaint of pollution in the case of stingrays.

Hundreds Of Stingrays Wash Ashore Dead In Campeche, Mexico

Tons Of Fish And Dozens Of Stingrays (Plus Other Sea Creatures) Turn Beach Into Mass Grave In Mumbai, India

Tons of dead fish and other sea creatures were washed ashore on the long stretch of the otherwise picturesque Juhu beach on Saturday morning, sending local residents and ecological experts into a tizzy. Rumour mills began doing the rounds about an impending ecological disaster.

When SUNDAY MiD DAY visited the site yesterday, among the dead marine life was a nine feet-long eel, a large (over five feet-long) octopus and dozens of stingrays. The entire stretch of the beach was full of dead sea creatures.

Complaining about his dead catch, 50-year-old fisherman Suresh Dandekar said he was anticipating a big catch of fresh fish, when he docked his boat at dawn. “Finding dead fish is nothing new for people like me, who have spent their entire life at sea. But what we have witnessed today is terrible. Not a single fish in the entire catch is fit for human consumption,” said Dandekar.

Trying his best to clear up the mess, China Tambi, a BMC cleanup marshall, said it was not possible for even a large team of workers to collect and dispose the dead fish. “Since morning, I have been witnessing fishermen emptying their catch of dead fish on the beach, as it cannot be sold in the market. How so many fish are dying is a mystery and can only be answered by an expert,” she said.

Official speak
SMD contacted Shankar Gajbaje, marine biologist and officer-in-charge of the National Institute of Oceanography (NIO), an autonomous research organisation. Based on the information given by this newspaper, he said his team of scientists was at the beach to collect samples, which would be analysed in their lab and ascertain cause of the mass death.

He added that a probable cause could be massive dumping by commercial trawlers in deeper waters. “Such dumpers are known to discard fish which do not have commercial value, or if they experience torn fishing nets.”

Promising quick action, Raju Vasave, regional officer, Maharashtra Pollution Control Board said he would dispatch his team of officers to investigate the matter. “There is no source of industrial waste in the vicinity of Juhu beach, so we can only plot the future course of action once the site is inspected and samples are collected for further analysis,” he said.

Investigations on
A three-member team from the NIO returned with samples later in the day. Amit Patil, one of the scientists, said the incoming high tide was making their efforts difficult, but they had managed to collect over 20 species of dead fish and crabs for lab analysis. “Prima facie, the samples are found only in deeper waters and finding them dead on the coast is a cause of concern. We have also collected water samples for our lab analysis,” said Patil.
