Thousands of dead fish found in a river in Limerick, Ireland

Fish Kill Alert

INLAND Fisheries Ireland (IFI) alongside the local authorities in Limerick and Tipperary are currently investigating a major fish kill that occurred on the Drumcamogue River, a tributary of the Camogue River near Knocklong, on Monday.
Some 4,300 fish, mainly trout and salmon, are expected to have been killed along a three-kilometre stretch of prime nursery area between Ballycahill bridge and Knocklong.
It is understood that the fish kill was caused by a slurry spill from a nearby farm, however the source has not yet been confirmed.
Limerick City and County Council has reassured members of the public that there is no danger to the public water supply.
Amanda Mooney, director for the Shannon River Basin District, said: “This is a heavy blow to the river especially with most of this year’s juveniles wiped out in a prime nursery area. I am asking the public to report any suspected discharge into any river to the IFI 24-hour confidential hotline 1890 34 74 24.
“At this time of year with lower water levels, rivers and streams can come under significant pressure due to runoff from silage making and slurry spreading. Farmers and contractors are advised to be particularly vigilant”.

About 10 000 dead fish were found last Friday stranded on a beach in the natural reserve of Moëze-Oléron in St. Froult. For now, the reasons for this mysterious massacre remains unknown.
Nature reserve managers had never seen it. It is they who discovered Friday, thousands of dead fish, and even today they are struggling to estimate the extent of the carnage: 10,000 certainly more fish, all washed up on the beach.
“The beach where they are stranded is nearly 5 kilometers long and there was a dead fish every ten meters in places but it was 20 or 30 fish were found every ten meters,” explains Pierre Rousseau, Babysitting technician wetland nature reserve Moëze-Oléron.
The fish almost all belong to the same species, these mules, an insectivorous species and herbivore.
The cause of death is not known. The specimen were collected and will be sent to the departmental direction of the territories and the sea (DDTM) to perform analysis. “Have the mules were victims of lack of oxygen due to the extreme heat of the last week or contaminated by a bacterium, it is unknown and remains for now at the stage of hypotheses. ” adds Pierre Rousseau.

900,000 chickens to be killed due to avian flu in Nebraska, USA

Bird Flu

No new cases of bird flu were found in Nebraska over the past week, but state officials say 900,000 more chickens will be slaughtered to limit the spread of the disease.
The Nebraska Agriculture Department said Tuesday the company that owns several farms where bird flu has been found agreed to kill the chickens on two other farms it owns in Dixon County as a precaution.
Including the new farms, nearly 5 million chickens are being destroyed on farms in northeast Nebraska to help control the bird flu.
Another farm in nearby Knox County with 3 million chickens remains under quarantine, but tests have not confirmed the presence of bird flu.
Nationwide, the virus has led to 47 million dead birds — mostly turkeys and egg-laying chickens.

Hundreds of fish are dying in Clear Lake in California, USA

Fish Kill Alert

Hundreds of carp carcasses have been found in and along Clear Lake, a sign that the deadly koi herpes virus may once more be infecting the lake.
In 2008, hundreds of thousands of carp died from the disease in Clear Lake. Last year, thousands of carp died in Lake Mendocino. The virus was suspected, but could not be confirmed in that case.
Lake County officials estimated the number of dead fish found so far in Clear Lake to be in “the low hundreds.”
“It’s not a huge thing,” county spokeswoman Jill Ruzicka said.
The dead fish, first noted Thursday, are scattered here and there throughout the lake and along the shore, she aid.
Carp die-offs occur periodically throughout the world.
When the goldfish relatives are the only dead fish found, the cause is probably the koi herpes virus, fisheries officials have said. Carp, which are an invasive species here, are hardy fish and would be among the last to die if the cause was lack of oxygen from water being too warm or too much algae growth, they say.
The koi herpes virus was first detected in the United States in 1998 and outbreaks have since been identified worldwide, according to the UC Davis Veterinary Medical Teaching Hospital’s website.
Virus infections could be triggered by people releasing their unwanted koi or goldfish into lakes, officials have said.
The disease is suspected of killing thousands of carp in Lake Ming near Bakersfield in 2010 and Lake Kaweah in Tulare County in 2009. Last year, an estimated 500,000 Asian carp died in the Cumberland River below Lake Barkley dam near Nashville.

Hundreds of dead fish washing up on beaches in Florida, USA

Fish Kill Alert

Multiple agencies, including the Florida Fish and Wildlife Conservation Commission, are looking into why hundreds of fish are washing up on local beaches.
Reports began rolling in over the weekend from people on beaches across Escambia, Santa Rosa and Okaloosa counties, according to Catalina Brown, the Fish Kill Hotline coordinator for the Florida Fish and Wildlife Research Institute.
“It’s too early for us to know what it could be,” Brown said.
Katy Krueger was out walking on Navarre Beach Monday morning when she encountered the dead fish.
“I counted to 100 and then I stopped counting,” she said.
She said the fish looked relatively fresh and were also visible in the water. A few seagulls were around, but they didn’t seem overly interested in the dead fish, Krueger said.
Brown said while they’ve seen photographs of the fish, the agency has a policy to only identify them in person, so the exact species washing up aren’t known at this time.
Officials suspect they are bait fish.
Water samples were also collected Monday and were expected to be at the research institute for testing by Tuesday.
Staff will be looking for various types of algae in the water. If that is ruled out, other options will be considered such as a net dump from a fishing boat.
FWC hasn’t had any recent reports of a red tide, she added. Algae blooms can happen at any time and the research institute is constantly monitoring Florida waters for it, according to FWC spokeswoman Kelly Richmond.
“If they were aware of a bloom, we would know about it,” she said.
If it is a red tide, people with sensitive skin are advised to avoid the water and others to wash well after exiting, Richmond said.
If it was a fish dump, the impact for bathers is limited.

Tens of thousands of dead white fish have washed ashore in Hong Kong’s Stanley district but authorities don’t know what killed them.
The massive fish kill covered a big swath of St. Stephen’s Bay in a silvery hue, Apple Daily reported Monday.
Most were sardines, thousands of which were spotted struggling in the water.   
A man, surnamed Chui, described the scene as “breathtaking”, with the water covered in a film of silver from dead or dying fish for about 30 minutes on Sunday.  
He said he tried to push some of the fish back out to the water but there were just too many of them.
Most had died, he said.
For a moment, Chui said he thought it was a sign of an impending natural disaster.
Scuba divers reported more dead fish further offshore.
In July 2013, thousands of small fish washed up on the Central government pier.
Experts said they might have been disturbed by severe noise caused by passing vessels or by extremely hot weather.
Chong Dee-hwa, chairman of the Ichthyological Society of Hong Kong, said the Stanley incident could have been due to noise from large vessels.
Also, low tides could have left pools on the sea floor, stranding the the fish and exposing them to extreme heat.
