Thousands of fish have died in the Jufeng Reservoir in Rizhao city in east China’s Shandong Province, due to heavy rains that had led to a sudden drop in temperatures in the reservoir.
Wang Yunying, a contractor working on the clean-up effort at the reservoir says that the area had experienced a sudden bout of heavy rain on September 11.
This had resulted in a rapid change in water temperatures leading to the death of thousands of fish, mainly silver carp and spotted silver carp.
According to Wang, the area had been affected by a long dry spell earlier. The reservoir’s water line had dropped steadily and the excessive amount of fish had led to oxygen deficiency in the reservoir.
But this issue was aggravated by the heavy rains, because as the cold rain water mixed with the warm water in the reservoir and affected the flow of oxygen to shawls of fish.
The reservoir management started to remove piles of dead fish that were giving out a foul stench since September 13.
It is estimated that the cleanup efforts will cost around 600,000 yuan, or around 94,200 US dollars.

Hundreds (maybe thousands) of dead fish found floating on a lake in Missouri, USA
A fish kill in Benton County left hundreds of fish dead. Nathan Manning was feeding his cows one day when he noticed dead fish floating in his fish pond.
“Oh, there’s thousands,” Manning said on Thursday. “I saw all the fish on the top of the water and some of them were dead and there were some still kind of swimming on their side and stuff.”
He contacted the Department of Natural Resources and the Department of Conservation but he says they couldn’t tell him what killed the fish.
“They said they didn’t really now what caused it for sure. They thought it was low oxygen level but I don’t think they test for a lot of different things,” said Manning.
Manning’s pond covers about six or seven acres and was once home to hundreds, but now most of those fish, both big and small, are dead.
“There’s bluegill and catfish and bass; I found a lot of them and I found some goldfish, too — somebody must have turned them in there at one point — but they were dead as well,” said Manning.
Now Manning and his family hope they can get some answers and save some of his fish.
The City of Lincoln says its water quality is checked every two weeks at its waste water lagoon that sits on an adjacent property to Manning’s land, and it tested safe, but Manning is still waiting to hear the results of the Department of Conservation’s water quality test.

Dozens of TONS of fish have died in fish farms in Vung Tau, Vietnam

Before that, starting from Jan. 6/9, fish birds, fish bớp in hundreds of cages of 16 households on the grinding and (Long Painted) surface and then die, estimated tens of tons, about 10 billion in damage.
That causes the dead fish is due to the seafood processing factory in Binhai wastewater River Township, 7/9 tens of households already pulling the regarding PPC headquarters of BA RIA-Vung Tau asked to solve, and households have taken dead fish dumped in front of a number of seafood processing plants as a form of protest.
Mrs. Truong Thi Huong, Vice Chairman of PEOPLE’S COMMITTEE of HO CHI MINH CITY Vung Tau, said the 2014, Long son fisherman’s friends fish have died many times with total damage amounting to more than $ 100 billion. But fish farming dies constantly for years but until now has not had an agency would identify specific responsibilities.

Tens of Thousands of dead fish wash up in a lake in Baytown, Texas, USA

Thousands of dead fish are washing up in one Baytown neighborhood, leaving behind a stink of a mess.
The fish are in the canals that fork off Burnet Bay. Eyewitness News found tens of thousands of in the canals behind the homes on Yaupon and Rue Oleans in the Lakewood subdivision.
A homeowner who lives along the waterway says she first spotted several dead fish early in the morning. When she came back from work in the afternoon, there were thousands of them beginning to rot under the hot Houston sun.
Eyewitness News reached out to Texas Parks and Wildlife. They tell us this is a seasonal issue that is common in many canal subdivisions due to low levels of oxygen in the water. High temperatures and algae blooms typically cause this.
“The kills typically happen overnight when much of the algae dies off and also produces less oxygen,” regional biologist Steven Mitchell explained. “These fish are juvenile Gulf Menhaden that gather in large schools and are drawn to these inland canals to feed on the algae and are very sensitive to environmental stresses.”
Mitchell says as the fish die, even more oxygen is removed from the water due to the decomposition process. That in turn causes even more fish to die.
“This large die off may in turn affect other species of fish if low dissolved oxygen persists day and night for several days,” said Mitchell. “The event usually lasts a few days until weather conditions change.”
Local birds and other animals in the water, like larger fish and crabs, will generally take care of most of the dead fish.

The Councillor responsible for the area, Xavi Ródenas, asked the Manager of the regional sewage treatment plant daily analyses of recent weeks to rule out that this is a problem in this plant spills.
Similarly, the company that manages the municipal water has moved technicians to the area, who have taken samples and sent them to the laboratories of Valencia for its study. You are expected in five days the results. You want to check if it’s a spill illegal in order to find out the origin and start the timely complaint.

Hundreds of dead fish found in a waterway in Spalding, England, UK
Hundreds of fish found in a waterway on the edge of Spalding died because of “low oxygen levels in the water”, according to environmental officers.
Dog walkers and passers-by discovered the fish lying dead in Vernatts Drain, near Johnson Community Hospital, on Friday and Monday.
Specialists from the Environment Agency used air pumps to raise oxygen levels in the water, repeating a similar exercise carried out nearly four years ago when hundreds more fish died in similar circumstances.
George Scott, chairman of Spalding and Peterborough Transport Forum, said: “I was walking my dog along Blue Gowt Drove and turned left towards the hospital when I saw what I thought were a lot of lilies out on Vernatts Drain.
“Then I looked again and saw hundreds of fish, including some big ones, dead in the water.
“I’d never seen anything like it before and someone told me that they may have been there since Friday.
“I remember when the fire service came out a couple of years ago to pump oxygen into the water, but I wasn’t sure whether it was a case of lack of oxygen this time.
“It’s good to report things like this rather than just walk past and ignore it because if it’s worth noticing then it’s worth reporting to somebody.”
During the summer, fish are in danger because of low rainfall and high temperatures which can lead to lower oxygen levels in the water.
Keith Morgan, team leader at the Environment Agency, said: “We have responded to a report of dead fish in Vernatts Drain, near Spalding, where our officers attended immediately and identified that this was due to low oxygen levels in the water.
“This is a fairly common occurrence at this time of year which can be caused by low water flows, water temperature or the weather.
“We have used aeration pumps to help increase the amount of oxygen in the water back to where it should be.”

100,000 fish killed after oil spill in a creek in Washington, USA
The Washington Department of Ecology estimates that 66,000 to 100,000 fish have died in Olequa Creek near Winlock after a fire last week razed a warehouse nearby, potentially releasing more than a thousand gallons of vegetable oil into the creek.
The fish include juvenile salmonids, steelhead rainbow trout, coastal cutthroat trout, brook lamprey, sculpin, crayfish and red shiners. An estimated 94 percent of the dead fish were sculpin, a bottom-dwelling fish.
Ecology and the Department of Fish and Wildlife have not definitively determined a cause of death, but the die-offs are presumably related to the oil spill, because oil can coat fishes’ gills, causing them to suffocate. Oil can also cause an algae bloom, which deprives the water of oxygen.
Ecology spokesman Chase Gallagher estimated all aquatic animals in the creek, which is a tributary of the Cowlitz River, have died in a 3.5-mile area below the spill. Gallagher said there have been no reports that the oil sheen has reached the Cowlitz.
WDFW biologists were not available Monday to put the loss into perspective.
Officials still don’t know how much oil spilled into the creek, but the company that owns the warehouse, Olympic Trading Corp., was storing at least 1,100 gallons of vegetable and canola oil inside.
Ecology contract crews have been cleaning up the spill since the fire burned down the warehouse at 803 NW Kerron St. and disgorged the stored cooking oil.
“The absorbents are doing a good job,” Gallagher said of the pads the department is using to mop up the oil. “All the reports are saying that … the clearness of the creek is improving.”
An investigation into a cause of the fire is ongoing.
