Wildlife conservationists are concerned after several aquatic animals were found dead on the bank of Timbi lake on the outskirts of Vadodara on Sunday morning.
A group of students from the Department of Zoology of M S University noticed dead turtles, snakes and fishes on the bank of lake when they had gone to the wetland on Waghodiya Road.
“We found six bodies of turtles, four snakes and one fish on the bank of the lake,” said Vikrant Vyas, a second-year student, who along with other students Ravin Kadu and Sujit Gohil noticed the dead aquatic animals.

Tourists come here from around the world to watch whales. It’s common to see humpbacks leaping out of the water and fin whales slapping the waves with their flukes. If you’re lucky, you’ll catch a gray whale poking its head out of the water to scope out the surroundings. And if you’re really lucky, you’ll see a blue whale — at up to 165 tons, the largest animal on earth.
But all is not well here this year. Gray whales are dying in large numbers. Since January, at least 167 North Pacific gray whales have washed ashore dead from Mexico to Alaska. That’s probably just a fraction of the number that have actually died. Most will have sunk to the sea floor; scientists call these carcasses “whale falls.” But the number of known deaths is high enough that the National Oceanic and Atmospheric Administration has declared an “unusual mortality event” — a pronouncement that has sent scientists scrambling to figure out what’s going on.
Events like this are often the first warning sign that something may be seriously amiss below the waves. Particularly striking is that many of the whales washed ashore have been emaciated.

On Saturday (June 22), Taiwan’s Bureau of Animal and Plant Health Inspection and Quarantine (農委會防檢局) announced that a poultry farm in Changhua County’s Fangyuan Township (芳苑鄉) was discovered to be infected with the H5N2 strain of the avian flu.
Out of concern for public welfare and to help safeguard other poultry operations nearby, the bureau ordered and carried out a culling of 27,960 nine week old chickens, on Saturday reports CNA.
This is the 26th confirmed case of a bird flu infected site in 2019 according to the report. In 2018, there were a total of 62 cases recorded.
The largest culling operation so far in 2019 also took place in Changhua, when 32,500 chickens were killed in February.
According to CNA, the owner of the poultry farm voluntarily alerted authorities of the presence of the disease among the livestock. As is standard procedure, officials from the bureau confirmed the presence and variety of the disease, before immediately ordering the chicken’s culled and the site disinfected.

Laos has reported its first cases of African swine fever (ASF), confirming outbreaks in the southern province of Saravane, the Paris-based World Organisation for Animal Health (OIE) said on Thursday.
The southeast Asian country reported seven outbreaks of ASF in villages in Saravane, which led to the deaths of 973 animals, the OIE said on its website, citing information from Laos’ agriculture ministry.
The disease, which is incurable in pigs but harmless to humans, has spread rapidly across China since last August and also spread this year in Vietnam.
China, home to the world’s largest pig herd, has so far reported over 120 outbreaks of ASF.

The death of several fish species off the coast of São Luís has worried experts. Biologists believe that the reproduction of some species in shallow coastal waters may be a possible cause of the death of fish found in beach sand.
Last week, large and small species of fish appeared dead in the sand of São Marcos beach. What caught the most attention was a mere one meter long, which is in danger of extinction. In adulthood, this animal can measure up to 2.5 meters and weigh 350 kg.
“A mere is hard to find. On the shore people are curious. I knew there was a mere, but personally had never seen,” said waiter Josivaldo Viana, who also saw the fish.

Scientists are puzzled by a disturbing trend in the waters along four Gulf Coast states: almost 300 dead and dying dolphins have washed ashore since February, about three times the usual number.
From Louisiana to the Florida Panhandle, coastline residents keep seeing a dolphin die-off. They’re all bottlenose dolphins, which live closest to shore, and many were adults. The single-day record is nine.
“I would say it’s concerning, and bordering on alarming, primarily because it’s a group of dolphins that have been impacted because of other unusual mortality events,” said Erin Fougeres, who oversees the NOAA’s Marine Mammal Stranding Program. Fougeres pointed out that this is the same area that was impacted by the Deepwater Horizon spill, the 2010 explosion on an oil rig that killed 11 people and carried oil hundreds of miles from the well.
Scientists are exploring several possible causes, from the lingering effects of the oil spill to skin lesions on many recovered dolphins that indicate freshwater exposure. It could also be chemicals, pollutants, or a combination.
“It’s an area where dolphins have been previously exposed to oil, they have compromised health. They have lingering health issues and so they are more susceptible to any additional stressor,” Fougeres said, adding “anything could tip them potentially over the edge.”
There’s a lot of work to do. “Even if the numbers stopped right now, we still have a long way to go, so the work isn’t gonna end,” she said, adding “We’ll be figuring out which tests and which analyses we need to conduct and we’re going to move forward with that.”
Whatever’s happening, there is no known threat to people.

In recent weeks hundreds of fish have appeared dead on the beaches of the municipality of Timbiquí, department of Cauca, as reported by Mayor Edison Castro who does not know the causes of the situation.
The Regional Autonomous Corporation of Cauca is responsible for conducting the investigation to determine what is causing “one of the most complex environmental emergencies that have occurred in the municipality,” according to the local president.
According to the complaint, this situation has been presented for 20 days, but it has become encruced in the last week.
In addition, the mayor said that at the moment it has not been ordered to stop the consumption of fish in the region, despite this the inhabitants fear that the animals are contaminated with mercury due to illegal mining in the area.
At the moment the results of the investigations are waiting to determine what to do about it.

For nearly a week, Da Nang Drainage and Sewerage Company collected nearly 2 tons of dead fish at Thac Gian Lake, Hai Chau District, Da Nang.
Dead fish began to appear from the last 12.6 days. Until now, fish still float around the lake. Pollution is very heavy.
Mr. Mai Ma – Director of Da Nang Sewerage and Sewerage Company said that the cause of the dead fish situation is due to the harsh hot weather, the rare mud in the lake is reversed, causing the fish to lack oxygen.
It is known that for many years at Thac Gian Lake, it has used the aquatic method with rafts to clean the water. However, Mr. Ma said that this method only helps to handle a certain part but cannot thoroughly filter water.
Meanwhile, in March 2011, Mr. Huynh Uy Dung or Dung, known as Dung “lime kiln”, expressed his desire to help Da Nang treat water at Thac Gian lake and Vinh Trung lake by microbiological method.
Da Nang leaders initially agreed but then proposed that enterprises move to trial treatment in the park lake 29/3 (Thanh Khe district). Mr. Dung’s side did not agree and withdraw the project.

A record number of sea turtles are stranded along the Texas coastline at the height of sea turtle nesting season, a marine wildlife advocacy group says.
A total of 159 stranded sea turtles were recorded in April — the highest number of strandings in one month since monitoring began in 1980, according to Turtle Island Restoration Network. Strandings have continued at a rapid pace, with 186 turtles stranded through May 21. Most of the turtles were dead when they were discovered.
Among the dead were 68 Kemp’s ridley sea turtles, the Texas state sea turtle and the world’s most endangered sea turtle, the group said.
A stranded sea turtle is one found alive on land, or in the water that is dead, injured or exhibits any indication of ill health or abnormal behavior. According to Turtle Island Restoration Network, it is often difficult to determine why a turtle become stranded. In some cases, turtles have interacted with fishing vessels and are found with gill net wrapped around their flippers.
