Previously, three samples were transferred to this center for analysis to find the active ingredient that can kill fish mass.
As a result, there are 17 basic indicators in seawater and 2 indicators of pesticides are in the standard. Particularly surfactant indicators (indicators not in standard 10-MT: 2015 / BTNMT) are higher than normal.
In addition to the above three water samples, Kien Giang DONRE collected 7 samples of water for analysis at the laboratory of the Monitoring Center under the Department.

Thousands of fish dead in a lake in Polk County, Florida, USA

Part of a once vibrant lake is now a deathbed for thousands of fish. Polk County has gotten several reports of a fish kill at Lake Hancock.
Kendall Thomas has been making a living off the fish he catches on the lake for decades. He said the water hasn’t been so low in years, and the mud his motor turns up as he drives his boat across the lake is evidence of that.
More proof sits on the other side of a dam on the lake. You smell it before you see it.
“Makes me sick,” Thomas said, looking at the thousands of dead fish in the water. “I made a living right there.”
Thomas said it’s Tilapia he’d normally be able to catch and sell. He blames the dry conditions and how much water is being released from the dam.
“Now I have to go somewhere else to catch fish and hope that I catch fish,” he said.
The water is about three feet lower than it was earlier this year, according to Thomas. Scientists with the county tell 10News the lack of rain and high temperatures mean there’s more algae than usual.
“So essentially the algae is stealing the oxygen out of the water, which then means it’s not available for the fish,” Tabitha Biehl, with Polk County Parks and Natural Resources, explained.
Whatever the cause, fishermen like Thomas are hoping for rain and hoping the water level on the lake gets back to normal. With no substantial rainfall in the forecast, it’s hard to say when that will be.

Hundreds of dead fish wash up in Navesink River in New Jersey, USA

State environmental officials are trying to determine what is causing a large amount of dead fish to wash up in the Navesink River.
The dead fish started appearing late last week, particularly in the waters off Marine Park in Red Bank, a popular spot for pedestrians as well as boaters.
The number of dead fish began multiplying this week, to the point that they were visible from almost every spot along the bulkhead at the park. They also surrounded several boats.
While doing routine algae sampling of the river at the park, staff from the Monmouth County Health Department noted stressed and dying mehanden, said Larry Hajna, a spokesman for the state Department of Environmental Protection.
Hajna said it could be the case of a predatory fish chasing a school of menhaden up the river where their large presence depleted them of oxygen.
DEP staff were on scene on Tuesday and a pathologist was scheduled to go to the site on Wednesday to collect some fish for analysis, Hajna said.
He said it appears to be relatively isolated situation with fish scattered in the area. Small groups of dead fish were pushed by the wind against bulkheads, he said.
He said it appears to be a result of bluefish and/or other predatory fish having chased the bunker into a confined part of the river with low salinity, where they consumed available dissolved oxygen and died.
The department has been studying the river to determine how to clean up its pollution, which studies have shown includes traces of human feces and animal waste.
The river is bordered by seven populous towns and its water quality has been downgraded several times since 2005.
Past studies have also shown pollution coming from leaking garbage Dumpsters and an overflowing water-oil separator.

Hundreds of dead fish found in a lake in Bengaluru, India

The gruesome sight and stench of hundreds of dead fish floating on Doddakallasandra lake on Monday morning shocked residents of a Bengaluru locality — an eerie resemblance to last year’s Ulsoor lake incident.
But residents of Konanakunte, Bengaluru had to wait over 24 hours surrounded by the rotting fish carcasses before authorities finally acted on their complaints and began cleaning the watery graveyard.
Residents say that the lake, divided by a sandbank, has two parts. In one part of the lake, untreated sewage water and construction waste is dumped rampantly. The other part, used for baths and domestic purposes, remains relatively clean.
Heavy rain on Monday resulted in the sandbank’s inundation and in the process, sewage and waste overflowed to the other half, residents said.
 Officials of the Bruhat Bengaluru Mahanagara Palike said they have deployed pumps to clean the lake.   
“It will take at least two weeks for the entire lake to be cleaned including filtering the water of the lake,” Krishna, a BBMP worker told TNM. BBMP workers also used coracles to clear out the foul-smelling fish remains.
Regional media attention of the incident also spurred the area’s corporator, Shoba Gowda, to travel to the site and overlook Doddakallasandra lake’s cleaning process.
“What I think happened was that the water has been polluted by the nearby construction sites. They have dumped their dirty water in our lake. This is why the fishes died. The rain made it worse because the sewage has now mixed with the cleaner water,” Dinesh, a resident, told The News Minute.
Although the lake’s deplorable condition is not new, residents said, they have never witnessed such a horrible scene.
Sayyed, a 70-year-old resident said, “The water was never that clean. It might have been earlier. This lake is used to rear fishes. It was not sparkling clean ever. It was less dirty but not totally clean but the fishes have not died before this time.”
Despite multiple attempts, the corporation could not be reached for a comment.
When the Ulsoor lake incident occurred in March 2016, experts attributed the death of thousands of fish to the depletion of oxygen due to highly poisonous pollutants that settle on the bed of the lake. The lack of oxygen leaves the organisms “gasping for breath,” one expert said.
Ramprasad, convenor of Friends of Lakes, an NGO involved in rejuvenation of lakes in the city said, “There can be two reasons for the oxygen depletion in the lake which resulted in the fish kill. The incident must have occurred between 2am-5am in the morning when the oxygen concentration is lowest.”
He said, “Apart from the sewage and chemical effluents, some supplement used by the fishermen could have also resulted in the oxygen depletion in the water.”
Authorities in Bengaluru have been called apathetic to activists’ protests to protect the city’s lakes. 
Even the National Green Tribunal recently asked the state authorities to make all city lakes free of pollutants within a month.
There have been multiple incidents of lakes catching fire or drying up due to pollution or encroachments.

100 TONS of fish die in lake Kunashak in Russia

Lake Kunashak is located 84 kilometers from Chelyabinsk, its area is 235 hectares. Representatives of the Mayak-57 Heritage organization reported on the ecological catastrophe on the pond. According to volunteer environmentalists, the culprit is a local tenant who poisoned the carp, carp and perch to populate the lake with larvae of more expensive and valuable species. The estimated volume of dead fish is about 100 tons.
For its part, the tenant shifts the blame on the road builders, who in the summer of 2016 built a bypass channel in the water protection zone. As a result, the water level in the pond fell to 1.5 meters, and in the winter the lake remained very shallow. In November, the air temperature dropped to -30-42 ° C, and the fish froze, and in the spring, when the ice melt, it surfaced.
The prosecutor’s office began to check the facts. To date, the Rosselkhoznadzor experts have determined that no poisonous substances have been found in the lake. From the surface of the lake the fish has already been harvested and will now be buried in the cattle graveyard on the territory of the Kunashak district.
