Mass Fish Die-Off. Global Disturbance.

Thousands of dead fish wash up along river in India

May 22, 2012 – INDIA – The problem of fish dying in large numbers has come to the fore of the banks of the Mula-Mutha (Bheema) rivers again. Fish have been found dead along the banks of the Mula-Mutha because of rising pollution and the latest in the series was recorded at Hatvalan near the Pune-Daund border last week.  Since last week, thousands of Mozambique Tilapia fishes were found dead on the river banks at Hatvalan in Daund division, about 76 km from Pune. The fish apparently died because of thick blackish water flowing in the river bed. Ironically, Mozambique Tilapia is considered as one of the most resilient species of fish, known to withstand unfriendly environmental conditions. To make matters worse, the same dead fish were taken to market to be sold by local fishermen. Pune and Mumbai are the primary markets for these fish. According to experts, in May freshwater springs that open into the river dry up, and hence the dissolving factor of oxygen in the water changes accordingly. This increases the pollution level, causing the fish to die. A study conducted by Jal Biradari and Maharashtra Vikas Kendra last year had shown that the nitrate level in the Bheema river was 10-50 mg per litre, whereas the permissible limit specified by the Bureau of Indian Standards (BIS) is 45 mg/litre. The natural nitrate level should be less than 1 mg/litre, but due to pollutants, the level has shot up. Dr Ashok Rasage, taluka medical officer of Daund, said, “For a week, large numbers of fish were found on the river banks. We have sent them and the samples of water to the state health laboratory and are waiting for the lab report.” Dr Sudhakar Kokane, district health officer, also confirmed the incident but said he would get more information from officials. –Pune Mirror


Dead fish wash up at Arcadia Lake

Posted on: 11:34 pm, May 16, 2012, by Adam Mertz
EDMOND, Okla. — Wildlife officials are trying to determine why dead fish are washing up on shore at Arcadia Lake. 

...some fish “belly up” in the water Wednesday.

“When the fish kind of just start popping up like that, it’s kind of scary,” fisherman David Cox said.

...The Oklahoma Department of Wildlife Conservation said the dead fish all appear to be white bass.

...“Fish kills are not that uncommon but usually they might take place later in the year when it is hot and dry and there is a problem with oxygenation in the water and that’s usually a typical cause,” Michael Bergin said, Oklahoma Department of Wildlife Conservation.

It is still unclear what may have killed the fish.

Tons of dead sardines just washed ashore on a Japanese beach, creating a bloody, hellish landscape. Sadly it's not unusual.
Starting June 3, massive amounts of dead sardines began clogging a fishing port called Ohara, located near Isumi City on the western side of Japan. A blogger named Kay for the Asian news site reported on Tuesday that the port was closed due to the emergency. Locals trucked tons of fish to landfills, according to the Daily Mail's Leon Watson.
No one knows exactly why this is happening, but other communities know the horror firsthand.
Other areas have experienced massive fish kills from algae blooms, red tides, toxins, changes in water temperature, and diseases. Commonly a lack of oxygen is at the root of the problem since fish need to absorb dissolved oxygen to live.
In Japan, Twitter user Yumi Hareyama shared a photo of the dead sardines with a caption that read in part, "Try to clean the sea with everyone."

Donghu Lake outside the park and the number of dead fish 

Sector response: these fish are put in, hypoxia leading to death due to transit and non-lake contaminated 2012-6-8 8:03:10 Jiangmen Daily Review
A large number of dead fish emit unpleasant stench, staff pay close attention to the salvage of dead fish.
Members of the public Mr. Guo to the East Lake Park every morning to morning walkers. 8:00 yesterday, he as usual outside the lake after Lake Park, I suddenly smelled the stench. "How inundated with so many dead fish on the lake?" Amazed, Mr. Guo quickly call the rebellion to the newspaper, I hope reporters can go to understand the situation.

Lake floating in the number of dead fish pedestrians have to cover the nose and over

Found dead fish East Lake outside the park and lake near the Rose Garden. Not come to shore, the reporter would have smelled the stench nostrils. Standing on the shore, you can see the number of dead fish floating on the lake. On the shore, the reporter saw a few garbage baskets and a long dip net.

"How the death of so many fish, not a lake what?" Flow Park, many people have seen floating dead fish, some people worry that the lake water quality problems.

...Is not a lake, a problem

At the scene, the reporter to interview the person in charge of an East Lake Park. He told reporters that the dead fish called bream, the morning of June 6, transported to and put into the lake, a number of extremely heavy as much.

Began to put on the same day afternoon, have been discovered dead fish. "He says with exasperation.

According to reports, East Lake Park, the lake is closed, not connected with the outside world rivers, the need to put some fish to eat suspended solids into the lake to keep the lake clean and put these fish will be in here. He said: lake fish species In addition to the new batch of put other fish have not died, so should not be a problem in water quality. "He speculated, may be due to the transit time is too long, plus temperature too high will lead to mass death of these fish in a short time.

The official said that the Park will clean up dead fish, landfill and compost. He said: "We will further study, look at the near future is not able to continue to put new fish into the lake."

According to the feedback of the municipal fisheries sector, these dead fish for silver carp, is four fish, one of a lot of people used to call bream, but also in Guangdong. On the cause of death of the fish, they have a preliminary understanding, not East Lake Park lake contaminated, but because of the recent high temperature, plus transit time is too long cause silver carp hypoxia, so just put the silver carp can not adapt to the East Lake Park closed the water environment, which leads to death.

More than 10,000 carp found dead in Blue Springs Lake

Posted: 06/06/2012
By: Mitch Weber By: Mitch Weber

BLUE SPRINGS, Mo. - Missouri conservationists are trying to solve a mystery in an area lake.

What started as a couple dozen dead carp turned into more than 10,000 in Blue Springs Lake.

Conservationists took water samples and couldn't figure out exactly what caused the deaths. Their samples have now gone onto a national lab for further analysis.

Between 500 and 1,000 carp have been killed everyday. Jake Allman, a biologist with the Missouri Conservation, started noticing carp with lesions under their scales the last few weeks.

"There's a little bacteria on the fish, but not enough to really have caused this," Allman said. "This feeding activity where they are brushing up against each other can actually spread whatever is making them sick."

If Allman had his way, this kill would only continue.

"Their spawning activity disrupts spawning of other fish. They root around in the shallows and uproot aquatic vegetation which is beneficial to native fish," Allman explained.

But it seems the carp are now starting to recover.

Lake officials are now keeping an eye on the E. coli levels in the water.

They had to close a swimming area during Memorial Day Weekend because of a threat of E. Coli from of all the dead fish.

THOUSANDS of fish have died after the lake they were in was contaminated.
Residents discovered the dead fish at Madeley Pool yesterday morning and spent the rest of the day trying to oxygenate the water to save other fish which were still alive.

    Madeley Pool

Buckets, paddling pools and even a baby bath were brought in to house the rescued fish.
It is not yet known what caused the death of the others.
The pool has been closed to fishing and upcoming matches will be cancelled.
Ralph Parsons, chairman of Madeley Pool Angling Club, which manages the pool, said: "We normally have between 7,000 and 10,000 fish in the pool. At least 5,000 of them must have died.
"The whole pool looked like a carpet with fish on the surface struggling to breathe.
"It is a close-knit community and we are a local club so everyone has pulled their finger out to try to do what they can.
"We have tried to take out as many alive fish as we can, but there is only so long they will last in paddling pools.
"They have been dying by the minute but we can't take them anywhere in case they contaminate other fish."
..."I think they had a reading of high pollutants about a mile away but that's all we know at the moment."
...In 2009, more than 15 ducks had to be rescued after an oil spill in the River Lea, which runs into Madeley Pool.
Thousands of fish also died from a suspected contamination in 2004.

Algae blamed for killing fish

MORE than 2500 fish have been found dead in the Swan River since the start of the month and officers believe a fish-killing algae is responsible.
The fish, mostly black bream, were found in a 13km stretch of the river between Bassendean and West Swan.

Swan River Trust systems manager Mark Cugley said high-levels of fish-killing microalgae Karlodinium had been detected in the upper Swan and a clean-up operation was under way.

He said part of the water had turned red and a fishy odour had been reported.

“The Department of Health advises that people should not swim in, or fish in, water with dead and decomposing fish,” Mr Cugley said.

“They should also keep pets and other animals away from the fish because they may contain high levels of bacteria.”

Earlier this year, about 5000 fish were found dead in the river and scientists were unable to determine what killed them.

Anyone noticing dead fish in the area should report them to the Trust on 9278 0900.


Are China's oil and gas pipelines to blame for thousands of dead fish in Burma's Arakan state?

Last week, a local Arakan paper released startling photos of thousands of dead fish along the Coast of Kyauk Phyu Township in Burma. While it’s not definitive what caused such massive amounts of fish to die, the proximity of the dead fish to China’s oil and gas pipeline projects and claims by locals that Chinese companies are blasting coral reefs with dynamite — a technique used to create gravel for the construction of seaports and oil and gas pipelines and to ease access for large ships — suggests the two might are connected. Since the blasts began occurring in 2009, local residents have witnessed an increasing scarcity of fish, as well as mass deaths of other aquatic animals such as turtles and prawns.
Since late 2009, China has been constructing oil and gas pipelines, as well as seaports, in the Arakan state without consent or consultations from the local people. Daewoo international is also constructing a natural gas terminal and offshore gas platforms in the area. The projects began without transparent environmental and social impact assessments, and little information has been available on the potential impacts to the fragile ecosystem, including mangrove forests and coral reefs that are critical to the local fishing industry, a primary means of survival for many local communities. On top of this, local authorities have placed restrictions on fishing activities in the area, further threatening local livelihoods.
Dead fish in Arakan state
Here at ERI we have blogged extensively on oil and gas pipeline projects in Southeast Asia, and the caution and planning that should be used if such projects are to proceed. Already, there have been well documented abuses associated with the pipelines to China, including corrupt land confiscation practices, environmental destruction, incidents of forced labor, and in northern Shan State, severe human rights abuses as the Burma army attempts to wrest control of the pipeline corridor from several ethnic armed groups, leading to violence against local people, and internally displaced persons.
Of the four million inhabitants of the Arakan State, a majority depend on sustenance farming and fishing to live, which in turn relies on clean water and stable ecosystems. The visual shock these pictures bring is followed by an equally shocking question of what millions of people will do if deaths like this keep occurring.

Oaxaca, Mexico. - After the discovery of a large number of dead fish in the lagoon complex Chachahua occurred in recent days, various agencies conducted field studies and parameters to determine the causes of this phenomenon.

Photo courtesy of
Overall coordination, agencies and academic institutions specializing in environmental and aquifer concluded that the lack of oxygen caused by the presence of algae caused the type Cochlodinium polykrikoides phenomenon called "Dinoflagenado" main cause of massive fish kills in the nature reserve located in Melchor Ocampo Tututepec.
According to State Institute of Ecology and Sustainable Development of Oaxaca, instances were several samples of water and several fish analyzed, concluding that the death was caused by species of algae, mainly damaging larvae and juvenile fish production by mass of mucus and decay in the oxygen concentrations.
This interagency group said that although this has killed hundreds of fish, there was some involvement in the other species on the lagoon complex, so we recommend making fishing activities normally.
Moreover, roads and landing strips of Oaxaca is dredging a channel to feed fresh water to the lake and reduce the effect of the algal population.
Also, the units involved in this research and analysis, will be aware in this area of ​​the coast, making the samples necessary for the early detection of various phenomena that may disrupt existing species in the lake and affect the people of place.
Participants in this study the National Commission of Aquaculture and Fisheries, the Federal Environmental Protection Agency, the National Commission of Natural Protected Areas, the Universidad del Mar, the Ministry of Health, the National Water Commission and the Committee on Safety Health Oaxaca and Aquaculture in coordination with the direction of National Park "Lagunas de Chacahua"

Liu Qiaoying, whose family lost four fifth of the abalones in a red tide, demonstrates a handful of dead abalones in Suao Township of Pingtan County, southeast China's Fujian Province, May 29, 2012. Abalone farms in the offshore waters of Pingtan have suffered from a red tide that occurred on May 25. Direct economic losses could be estimated at 220 million yuan (34.8 million U.S. dollars), as more than half of the area's 100 million abalones have died as a result of the algal bloom. Local authorities are making efforts to help abalone raisers minimize their losses. (Xinhua/Zhang Guojun)
FUZHOUMay 29 (Xinhua) -- Eight red tides have occurred this year off the coast ofeast China's Fujian provinceand the algal blooms have killed millions of abalone,according to local authorities.

Investigators are trying to find out what caused a massive fish kill below Neely Henry Dam in Ohatchee.
The fish were discovered Monday morning by an Alabama Power worker reporting to his shift at the dam. He saw a few dead fish before dawn, then in daylight saw many more.
The state Department of Conservation's Wildlife Division joined officials with ADEM and Alabama Power Monday morning to take fish, temperature and water samples. They estimate some 13,000 fish were killed in a very short period of time either late Sunday night or early Monday morning.
Most of the fish were smaller fish like shad and drum, but some larger game fish, including crappie, catfish, and bass, also started washing up.
Dan Catchings, who works with the Wildlife Division's Eastaboga office, says it wasn't an oxygen problem because the fish had plenty of oxygen. He also doesn't believe it was bacteria or parasites, because the fish would've died more gradually if that were the case.
"A bacteria kill, or disease kill, will begin at low numbers and will accumulate over a period of days, the numbers will increase. But this has been a real sudden occurance," Catchings told Fox6 News
"There's apparently something toxic in the water that's working on the fish," Catchings added. "Something affected them very quickly and very acutely."
Catchings added there was no release of water just prior or during the period of time in which the fish apparently died, and no fish appear to have died above the dam.
Alabama Power spokesperson Allison Fuqua told Fox6 News the dam has released water since Monday's on-scene investigation, including a few times Tuesday. She says that may happen several more times in the next few days in hopes of removing the dead fish, the odor, and whatever killed them.
Tuesday the fish were starting to wash ashore at the Harts Ferry Boat Launch just off Highway 77. A large amount of them could be seen bobbing in the waters just beneath the dam, as fisherman still held out hope of catching live fish in an area known for especially large bass and catfish.
But some of the fishermen, including Virgil Gray of Pell City, said they'd likely throw their catch back in lieu of the fish kill.
"I've been out here about six times, we've never seen nothing like this. It's just unusual," said Gray. " I mean, I've been in ponds in Minnesota, Nebraska and everything else, Missouri, but I ain't ever seen anything quite like this."
Samples were taken by ADEM to a state lab for testing. Investigators say it could be a week before results turn up from any of the samples.
