6 TONS of fish die in a pond in Diepenbeek, Belgium

For club chairman Benny Wolfs this is a catastrophe.

The Diepenbeek fishing club “patience” is in deep trouble after a parasite and oxygen deficiency in the fish Pump Erik heavily thinned. “A disaster,” says club president Benny Wolfs. “The work of the past decade has helped here in one go for soap. This story takes our club more than 25,000 euros

The tears are Benny closer than laughter. Six tons, 6,000 kilograms of dead fish has been scooped out of the pond and still is not, at the end. “A catastrophe, in other words, I have not,” sighs Benny. “We have worked a whole week with might here. The fish are taken out of the pond and then stopped in special bags which they are discharged by a rendering plant. If you count that one kilogram of fish cost us an average of four euros, is the bill to over 24,000 euros. We have already rented for 1000 euros machines this week, and we pay 125 euros per ton of delivered fish. Count it. And then we have the help of the municipality and the fire of Hasselt, who have stepped in, fantastic not counted. But worst of all is that we have done to get over it. “Fish in our pond together at least 10 years.


“We need to look ahead, despite all the misery. It has now decided this calendar year to allow our pond. Fishermen no longer We have to restore the water in peace and recover from this blow. We do this through the installation of a fixed aeration system and by adding some sort of lime to the water. After that we will gradually assert fish in the water again, so that from next summer season can be fished. Fully again Here we go really work toward. And at the same time we want the link to the stream, which flows around here and there today is not real, trying to recover. That should improve the aeration of the pump Erik. However, a defect like this I really do not live to see. “

Mass Dolphin die off continues along east coast of America

Almost every day the bodies wash ashore. Sleek, once-powerful swimmers now lie in the surf, wasted by disease and pocked by lesions. Sometimes fishermen spot the creatures in their final throes of illness, swimming erratically before stranding themselves on the beach. The death toll has now climbed to 1,441.
But more than a year after the die-offs started to climb upward, scientists are still grasping for answers about the cause of the bottlenose dolphin deaths that have piled up since last summer along coastlines from New York State to Florida. The leading theory is that a pathogen called cetacean morbillivirus, an RNA virus related to measles, is fueling the deaths. And many of the creatures have tested positive for the disease. But the epidemic among the beleaguered creatures has shown only slight signs of slowing: 65 dolphin deaths occurred last month, nine more than in June, but more promising than the 114 body count in July 2013.
On the Virginia coast, where dolphins have been hardest hit, the average yearly toll for strandings is 64. But since last July nearly 400 dolphins have washed ashore just in that one state. By all measures, the death toll appears to be worse than past epidemics, lasting longer and taking a greater toll than the one caused by morbillivirus infection some 25 years ago. From the summer of 1987 through May of the next year, 742 dolphins died from that virus.
The good news is the current die-offs appear to be limited to dolphins—researchers have not noticed any mortality increase in other sea creatures—which suggests, alongside other evidence, that the killer is not something like algal blooms. Yet dolphins’ place at the apex of the food chain also raises the specter of bioaccumulation of toxins playing a role in the dolphin deaths.
But unlike the 1987–88 epidemic, the National Oceanic and Atmospheric Administration (NOAA) now has a network of experts and volunteers who report and collect the carcasses of the stranded dolphins and attempt to determine the cause of death. Unfortunately, answers have still remained elusive. Indeed, researchers feared last fall that whatever was triggering the deaths would trickle southward with the migrating dolphins and affect dolphin stocks living there year-round, and at least some of those fears were realized. Even while the deaths stalled in Virginia this winter, the numbers climbed in North Carolina and Florida waters, where dolphins had migrated for the wintertime. In their travels they apparently mixed with new dolphin pods—creating ideal breeding grounds for infection to jump from one dolphin to another as the mammals played, fed and breathed together.
Now, scientists and volunteers will be watching their phones in the coming weeks, hoping for a reduction in reports of dead bottlenose dolphins. A slowdown soon would suggest the population of remaining animals will not be further decimated when the cycle of migration repeats this fall. But only time will tell.
Investigating the deaths has come with a steep price tag. A combination of federal, state and private funds has been spent on the investigation so far, with almost all of it earmarked for the increases in staff needed to perform necropsies or process the dead samples (including about $200,000 in federal emergency grant funds). But almost none of the money supported forthcoming testing work to glean more details about the ages and identities of the dolphins.

More potent threat

Although morbillivirus remains the prime suspect—it has been found in 240 of 250 tested dolphins—a barrage of other microbes has been found in the creatures as well. For example, 20 out of 64 dolphins harbored brucella, a bacteria that causes miscarriages, brain infection, blubber abscesses and pneumonia in marine mammals. That presents a complex chicken-or-egg question: Were morbillivirus-weakened dolphins prone to contracting other sicknesses? Or, is some combination of different pathogens striking the initial blows against the dolphins?
Moreover, if more dolphins are dying this time around, does that mean that this strain of morbillivirus is somehow more lethal than the outbreak that tore through the dolphin communities a quarter century ago? Researchers do not expect to have definitive answers anytime soon. “If the mortalities don’t pick up again this summer, we hope to have preliminary conclusions in winter—probably January or February 2015—and a final comprehensive report would be available, hopefully near the end of 2015 or early 2016,” says Deborah Fauquier, who is heading up the day-to-day operations of this investigation for NOAA’s National Marine Fisheries Service. Although the virus is related to the microbe that causes measles in humans and distemper in canines, this dolphin-killing pathogen poses no threat to humans. And so far there has been no evidence that the virus can jump to other species, but still NOAA advises humans not to approach sick or dead creatures.
This fall scientists plans to melt down thin slices of the quarter-century-old wax that contain DNA samples from the virus and compare its sequence to that of the current viral strain, and other strains, too—hoping to find signs of mutations that may explain the current outbreak’s potency. NOAA also plans to award contracts to scientists who will genetically test the dead dolphins to confirm what types have died. Normally, a lot of that identification would take place by comparing the animals’ dorsal fins, but because the carcasses often wash ashore in an unidentifiable state (read: thoroughly decomposed or chewed on by sea life) their exact identities have often remained mysterious. Other researchers will conduct testing on the dolphins to look for signs of biotoxins that may have also played some role in the dolphins’ deaths.
Still, with no vaccine or treatment for dolphins suffering from morbillivirus in the wild, this new data will likely only equip responders to better save the existing population—safeguarding the habitat of certain bottlenose dolphins that have been hit the hardest.

Massive fish kill ‘due to algae’ in a lake in Kansas, America

Fish Kill Alert

The spread of blue-green algae is blamed for a large scale fish kill at Veteran’s Lake in Great Bend. It’s one of ten Kansas lakes now under the blue-green algae warning from the Department of Health and Environment.

Great Bend city workers pulled thousands of dead fish from Veteran’s Lake Thursday and Friday and thousands still remain. As each hour passes the blue-green algae problem seems to get worse.

“We’ve lost carp, cat fish, bass, crappie, perch you name it,” said Great Bend Director of Public Lands, Terry Hoff.
“Even the minnows, it’s pretty rare anything like this happens around here.”

It’s not just a danger for fish, signs are posted around the pond warning people to stay out of the toxic water.

Hoff said this is a serious issue. “It can cause gastrointestinal disease, it can cause rashes it can be harmful to both people as well as pets.”

Gary Bauer brought his two grand kids to the lake, but said this issue isn’t new.

“It don’t make us feel real good because we would like to go play in the lake and do a little fishing because there is worthy fish in here to catch for little kids,” said Bauer.

The problem spans across the entire lake, it even has a bluish-green tint to it.

The city placed several machines in the lake to pump oxygen into the water, but that hasn’t seemed to help.

“For whatever reason I don’t think those diffusers can keep up with the problem at this particular point,” said Hoff.

The city believes the problem is worse than ever before because of high phosphorus levels in the water caused by storm runoff and a huge geese population on the lake. It might cost the lake all of its fish.

“We want to reclaim it and intervene. If we can do it safely so it’s not going to have an impact on people, on the wildlife in the lake or anything like that,” added Hoff.

Officials said it is still OK to fish at the lake and even eat the fish you catch. Make sure to filet the fish, clean them with clean water and through out the remains.

Hoff said they’ve hired a private consultant to help them figure out how to deal with this issue. They expect the problem to cost more than ten thousand dollars.

Thousands of dead fish wash up in Bursa, Turkey

Thousands of dead fish found, ‘worst fish kill ever’ in a lagoon in Langley, Canada

Thousands of invasive fish found dead in Langley, Report

It was the worst fish kill ever recorded at the 29-year-old lagoon.

Sarah Atherton with the Langley Environmental Partners Society says crews spent the day cleaning up the Brydon Lagoon- a man-made old sewage settling pond.

She believes the fish kill was caused by an algae bloom last week.

“Some of the European carp in there were a good one to two feet long, so they’ve been in there quite some time. Possibly from people not wanting them in their backyards, ponds or home aquariums, and then releasing them in the lagoon.”

A statement posted on the society’s Facebook page says “suspected low dissolved oxygen is the culprit from an algae bloom that occurred in the lagoon last week. Algae blooms are common at this time of year in closed systems as a result of high nutrient levels (perhaps from lawn fertilizers etc) and increased water/air temperatures. Oxygen levels fluctuate depending upon the growth cycle of the algae.”

The society says the lagoon is not suitable salmon habitat, and many of the fish killed were invasive species such a European Carp, Catfish and Pumpkin Sunfish.

Atherton says luckily no native fish populations were affected.

Thousands of fish killed ‘due to pollution’ in a river in Suffolk, England

Stour Brook
Environment Agency staff have been aerating the brook to improve oxygen levels

The “entire fish population” in a stretch of a Suffolk brook is likely to have been killed by pollution, the Environment Agency said.

About 2,000 large fish and thousands of smaller ones have died in Stour Brook near Haverhill since Tuesday.

Anglian Water said a problem with its Haverhill water recycling centre had led to sewage entering the brook.

The Environment Agency confirmed the fish died “from a lack of oxygen caused by a pollution”.

A spokesman warned people to keep their dogs away from the water.

Anglian Water said it was doing everything it could to “remedy this situation”.

“Our alarm systems alerted us to the problem immediately, and we dispatched engineers to the site to investigate the problem.

“We are working closely with the Environment Agency to assess the situation, and to protect and restore the brook.”

Environment Agency staff have been aerating the brook, which leads to the River Stour, and oxygen levels have now returned to normal.

A spokesman confirmed pollution had killed the fish in a 3km (1.9 miles) stretch of the brook but it had not reached the river itself.

Large amount of dead fish found floating in a river in West Bangal, India

Fish Kill Alert

There was a stir Wednesday in Bidhan Nagar area of Siliguri town in West Bengal when a large number of fish was found dead and floating on the Motia river, an official said.

Panic-stricken residents moved their cattle away from the area, fearing they may die after drinking water from the river in Darjeeling district.

They also kept vigil so that no one took the fish to the market for selling.

A team from the state fisheries department went to the spot and collected samples of the river water and the dead fish.

“The samples are being sent for forensic examination,” said deputy director of the department’s North Bengal zone Uttam kumar Panja.

Large fish kill found in the Kishwaukee River in Illinois, America

Fish Kill Alert

The Illinois Environmental Protection Agency is investigating a large fish kill near Huntley, but the answers may be coming from half a world away.

The dead fish and other aquatic life began floating to the surface of the Kishwaukee River, its tributaries and a popular fishing lake last week, according to nearby residents.

“There were hundreds and I mean hundreds of dead fish everywhere,” said Craig Hall, a resident of the Sun City Huntley community.

The affected bodies of water are close to a section of I-90 where a truck carrying a concrete curing compound caught fire on July 25 and created a traffic jam.

Could the two events be connected?

A spokesperson for the Illinois EPA said it is believed that the concrete compound carried by the truck as well as firefighting foam entered a nearby ditch after the accident.

However, sample test results that may help determine the cause of the fish kill have not been returned.

According to the Illinois EPA, the samples were sent to a lab in Singapore. It is apparently the only lab available that can develop the standard for the analysis of the water samples. But state officials say the samples are being expedited.

“For fish to die in that scale and of every species, I knew something was seriously wrong,” said neighbor Kyle Vandermeer.

Signs posted near the lake warn of possible contamination. The state said it is believed the incident is currently contained and under control.

Huntley is about 50 miles northwest of Chicago.
