Texas: Hundreds Of Thousands Of Dead Fish Found At Lake Wichita

07/04/2012 Leave a comment

“It’s another case of dead fish in Lake Wichita. Hundreds of thousands of dead fish were reported to Texas Parks and Wildlife officials Monday morning.

Fisheries Biologist Robert Mauk investigated the incident and took samples back to his lab. What he found was golden algae. The algae release a toxin into the water that make it difficult for the fish to breathe, eventually leading to suffocation.

Carp, catfish, crappie and other species are dead, some still struggling to survive. Mauk refers to this as a ‘major’ fish kill.

‘This is probably the 4th golden algae related fish kill at this lake,’ he said.

Mauk doesn’t expect a total fish kill. The cause of how the golden algae bloomed inside the lake is unknown. The area was hit hard by golden algae at the start of the year, now it’s happening again. Only this time it’s worse. To read our January report of golden algae at Lake Wichita click here.” Source – Newschallel6Now.com.

Thousands Of Fish Found Dead In Illinois, Missouri, Georgia, South Carolina – High Temperatures Blamed

07/04/2012 2 comments

Residents Concerned Over Thousands of Dead Fish in Havana, Illinois – “Dead fish carcasses, maggots by the thousands invading their eyes, and a smell that would raise anyone’s nostril hairs… It’s what the shore of Quiver Creek attached to Chautauqua Lake in Havana looks like. ‘We’ve never had fish, dead fish float up on our banks, like we see here. I buried probably at least a couple ton of them the other day,’ said concerned resident Rick Hartmeyer. According to the IDNR, summer fish kills are a result of natural conditions like hot weather and low water levels but Hartmeyer says this was intentionally done by the U.S. Fish and Wildlife Service. And that’s something officials say is not true.” Read more.

Thousands of Dead Fish Found in Dexter, Missouri- “DEXTER, MO (KFVS) – Thousands of dead fish turned up over the past couple of days at Dexter City Lake. It’s an important image for residents like Dean Smith. ‘My son fished over there when he was small,’ said Smith. He knows the importance of the community pond because he has lived in Dexter, Missouri his whole life. ‘There’s people that come there everyday and fish,’ said Smith. But right now, signs say no fishing. That’s because thousands of fish are dead and officials blame our triple digit weather. ‘Well the high temperatures, which is unusual with this many days over 100 or near 100, is heating the water temperature up which has an effect on the oxygen level in the pond,’ said Lawson Metcalf with Dexter Parks and Recreation.” Read more.

Thousands of Dead Fish Wash Ashore in Butts County, Georgia – “Thousands of dead fish have washed up on the shores of a lake in Butts County. Georgia Department of Natural Resources officials estimate around 2,300 carp, bass and catfish have died in South River in Butts County. Sean Ledford, who owns a house in a cove of Lake Jackson, says the smell of the fish is so bad that he can’t even use his dock. ‘We’re out here trying to celebrate and you just got rotten smell being blown in your face,’ Ledford said. DNR officials say low water levels and high temperatures caused the fish to suffocate.” Read more.

Hundreds of Fish Killed in Upstate Lake in South Carolina – “Hundreds of fish are floating dead in an Upstate lake, but the cause was not a mysterious chemical or some other pollutant. The Department of Health and Environmental Control says low water levels combined with heat has led to a lack of oxygen in the cove on Lake Hartwell near the Fair Play area. About 500 fish have died. Brandi Pierce and her family live just yards from the waterway. ‘It started Sunday afternoon,’ Pierce said. ‘We started seeing ten fish popping up out of the water. Then Monday, it was full.’ DHEC spokesman Adam Myrick said fish kills are very common when temperatures are extremely high.” Read more.

Florida Fish And Wildlife Conservation Commission Studying Lake Buffum Catfish Dieoff Near Fort Meade

07/04/2012 1 comment

By Tom Palmer – “I received a report over the weekend about a fish kill on Lake Buffum near Fort Meade.

Instead of being the normal fish kill that involves a drop in oxygen levels caused by an algae die-off that leaves fish floating everywhere, this one affected only catfish, I was told.

I spoke with Eric Johnson, a fisheries biologist at FWC’s Lakeland office.

He confirmed the report. He said tissue samples have been sent to a state lab in St. Petersburg to get more accurate info, but tentatively it appears to be the result of bacteria or some other microorganism.

Johnson said this occurs occasionally and there’s really nothing that can be done about it but to let it pass. Fish populations eventually recover.

This has been going on for a few weeks, Johnson said.

I’m surprised no one had contacted us–they usually do–but public access to the lake has been limited for some time because of the drought has made the boat ramp unusable.” Source – Polk Outdoors.

Canada: Hundreds Of Dead Fish Line The Banks Of Pottersburg Creek, Ontario

06/29/2012 1 comment

By PATRICK CALLAN, The London Free Press – “Hundreds of dead fish lined the banks of Pottersburg Creek Thursday morning and dozens more could been seen floating belly up from a small bridge on Industrial Rd. south of Oxford. St.

The roughly 500 dead fish ranged from a few inches to a foot long. The stench of fish hovered above the 150- metre stretch at the most westerly point of the creek where the dead fish were found.

The Ministry of Environment said water samples were taken from the creek Wednesday and testing is being done to determine if the fish kill happened because of a spill or natural causes.

Rick Pedlow, city of London sewer operations division manager, said the city found out about the fish kill Wednedsay and is working closely with the Ministry of Environment – who is taking the lead.

‘We’re just a resource for the ministry. They will give us direction,’ Pedlow said.

By Thursday afternoon, the city had begun cleaning up the dead fish.

The Upper Thames Conservation Authority said the fish — creek chub, darters, bluntnose minnow, rock bass and white suckers — most likely died of natural causes.” Read more.

Ireland: ‘Large Quantities Of Dead Fish Have Been Seen Flowing Downstream All Day’

06/29/2012 Leave a comment

RTE News – “It is understood that the problem was first noticed this morning and that large quantities of dead fish have been seen flowing downstream all day.

A statement on the Wicklow County Council website said that they have temporarily shut off raw water supply intake from Vartry River to our Water Treatment plant at Cronroe as a precaution.

Local sources said reports had been received of dead fish as high up the river as Roundwood, and as far down the river as Ashford.

It is also understood that a dead heron has also been found, although it is not clear if this is related to the fish kill.

A source in Inland Fisheries Ireland confirmed the matter is under investigation, but would not speculate about how extensive the problem is or what the cause might be.” Source – RTE News.

Australia: Dozens Of Dead And Dying Sea Turtles Washing Ashore Shows No Signs Of Slowing Down

06/29/2012 Leave a comment

AAP – “THE death toll of vulnerable green sea turtles south of Townsville has shown no signs of slowing down, with more sick animals washing up on beaches today.

Queensland authorities have carried out two helicopter surveys after more than 20 of the vulnerable species, mostly adult females, were discovered washed up on beaches around Upstart Bay last week.

Two more were found on Friday on Wunjunga Beach, about 100 kilometres south of Townsville, and their cause of death continue to baffle scientists.

A total of 73 dead turtles have now been discovered.

Marty McLaughlin, operations manager at Queensland Parks and Wildlife Services, says the turtles were nourished with no obvious signs of illness.

‘This is classified as an unusual event,’ Mr McLaughlin told AAP.

‘We now have better data about the number of turtles, but they are continuing to wash up.

‘We still can’t rule out poisoning as toxicology reports have yet to be finalised.'” Read more.

Congo: Livestock Disease With 86% Mortality Called Worst Epidemic In Decade, 1.6 Million Goats And Sheep At Risk

06/28/2012 1 comment

Associated Press – “ROME — A U.N. agency has warned that a livestock epidemic in Congo that has killed more than 75,000 goats is the worst in a decade and is now threatening goats and sheep in neighboring countries.

The disease, called peste de petit ruminants, or PPR, is highly lethal, with an 86 percent mortality rate among goats. It is caused by a virus that is similar to measles in humans.

The U.N. Food and Agriculture Organization said 1 million goats and 600,000 sheep are at risk of contracting the disease. To protect them, farmers have been moving their herds away from infected villages, but that has only spread the epidemic to healthy flocks of animals.

FAO said it plans to vaccinate at least 500,000 animals and will try to limit the animals’ movements.” Source – The Washington Post.

Georgia: Biologists Investigate Cause Of Thousands Of Dead Fish On Carter’s Lake

06/26/2012 Leave a comment

By Kimberly Barbour, WRCB – “CHATSWORTH, MURRAY COUNTY, GA (WRCB) – The Georgia Department of Natural Resources is investigating why several thousand fish have died in one Murray County lake.

Georgia DNR biologists say they’ve been getting complaints since Saturday from boaters, fishers and swimmers on Carter’s Lake.

It doesn’t take long to spot fish belly up on Carter’s lake. Silver sprinkles cover the blue water from end to end.

‘Dead fish just floating, I just wondered what was causing it,’ boater Jana Manous said.

‘I noticed that a lot of shad were dead,’ fisherman Carl Melear added.

It’s the first time frequent Carter’s Lake fisherman Carl Melear says he’s ever seen this many dead fish.

‘I don’t know what might be causing a kill like that,’ Melear said.

With lingering questions, intense heat and several hours with no catch, he decided to pack up early.

A few days into their investigation, DNR officials say they’re leaning toward it being natural causes instead of toxins in the water. That’s because all the dead fish seem to be the same species.

‘If it was a toxin in the water or low oxygen in the water, it would be killing all different types of species,’ said Jim Hakala, Georgia Dept. Of Natural Resources Fisheries Biologist.

State biologists came out to the lake this weekend to look into the reports and after seeing it for themselves, say nearly all of the dead fish are eight to ten inch gizzard shad.” Read more.

Hawaii: Avian Botulism Outbreak Kills At Least 67 Birds In Kahului

06/25/2012 Leave a comment

RSOE EDIS – “Wetland biologists and others involved in managing lands with associated wetlands have been notified by the Department of Land and Natural Resources’ Division of Forestry and Wildlife (DOFAW) of a recent avian botulism outbreak affecting waterbirds on Maui. In just over a week, 67 birds have been found dead at Kanaha Pond Wildlife Sanctuary in Kahului including Hawaiian Stilt, Hawaiian Coot, and Hawaiian Ducks of adult and juvenile stages. The paralytic disease has killed adult birds on their nests, also causing the eggs to be lost. Because botulinum toxin can be produced in most wetlands, and transported to new wetlands by dead or dying waterfowl, landowners and managers, both public and private, are being asked to frequently survey their wetlands for sick and/or dead birds, remove any dead or dying birds from the wetland, and contact local DOFAW biologists for guidance. Earlier this year a botulism outbreak in Hanalei, Kauai resulted in over 300 sick and dead birds being collected by USFWS refuge staff. Additionally, numerous other botulism fatalities have also been reported at wetlands throughout the state. Botulism is a paralytic condition brought on by the consumption of a naturally occurring toxin produced by the bacterium Clostridium botulinum. It is an intoxication rather than an infectious disease. Botulism, type C is commonly found in Hawaiian soils and is NOT dangerous to humans.

Particular environmental conditions in wetlands will sometimes allow this bacterium to produce botulinum toxin; the toxin is then accumulated in aquatic invertebrates. It is consumption of these toxic invertebrates by waterfowl that leads to mortality.” Read more.

Australia: Mystery Turtle Deaths Stump Scientists In North Queensland

06/25/2012 Leave a comment

The Telegraph – “THE mysterious death of 22 green turtles, a protected species, is puzzling experts in North Queensland.

The experts have not ruled out poisoning and even drowning as a cause.

The Department of Environment and Heritage Protection is investigating the deaths of the turtles found at Wunjunga Beach, about 100 kilometres south of Townsville.

The department’s director of threatened species, Wolf Sievers, said the vulnerable animals have been washing up on the beach for over a week.

‘It is very unusual for this many turtles to have stranded on one beach and we will be making every effort to establish what may have happened,’ Mr Sievers said.

Senior turtle expert Dr Ian Bell said that initial investigations found no injuries, no obvious signs of malnutrition or illness.

‘It’s a bit like turtle CSI, it’s all about ruling out possible alternatives,’ Dr Bell said.

‘We’re ruling out starvation. It doesn’t look like it’s any infectious type of disease, and it leaves us with two possibilities.

‘One is potential poisoning, and we’re also looking at the possibility of a drowning.

‘At this stage we really don’t know.'” Read more.

India: Authorities Order Investigation After Thousands Of Fish Die In Gomti River

06/25/2012 Leave a comment

“Authorities in Uttar Pradesh Monday ordered a probe into the death of thousands of fishes which have died in the river Gomti here.

The possible reasons that could have led to such largescale deaths, Jal Nigam officials said, would be looked into.

The deaths came to light when morning walkers and other residents who take bath in the river banks at Tuliyaghat saw thousands of fishes floating in the water.

No sooner did the news spread that fishermen jumped into the river with nets to gather them.

‘If true, this matter is serious and a thorough probe would be ordered into the death of the fishes,’ said Rajendra Kumar, chief engineer of the Jal Nigam unit.

Greens say that in the past few days the water level of the river had gone down considerably, leading to oxygen scarcity.

In the past weeks, there have been talks of water being released into the river by the Sharda canal but the depleting water level of the Gomti speaks otherwise.

Officials say that from time to time they check the oxygen levels in the river and it invariably comes around 5-6 miligram per litre, which is considered safe.

Fishes, they say, die after the oxygen level slips below the 3 mg per litre.

There is an immediate need for dredging in many parts of the river, official sources told IANS, but added that the Jal Nigam was ignoring this for a long time.” Source – daijiworld.com.
