You drive backwards into the water – thousands of fish are in spree, shipping and Landwehrkanal died, swim on the surface of the water.
Near the main train station, stop people on the river Spree again, consider the sad phenomenon. Some take pictures of dead animals.
Cause of fish death is the big rain by the weekend, when Saturday moved several storm fronts over Berlin and after weeks without large precipitation the filth from the streets into the mixed water channel system flushed.
Petra Rohland, spokeswoman for the Senate Administration for the environment, said the B.Z., many micro bacteria in spree and channels were reached with the rain water. This was to reduce the already low oxygen content, the fish could no longer breathe.
Perch, Roach and eels are particularly affected. A company was now tasked with the recovery of dead fish. Before the carcasses are burned, document what species it is.
The fish kills is a typical urban problem, said raw land. It should also be analysed whether this year’s fish dying is more dramatic than in previous years.

1 MILLION chickens to be killed due to new outbreak of avian flu in Iowa, USA

Bird Flu

After a six-day break with no new bird flu cases, the Iowa Department of Agriculture says another egg-laying chicken farm has tested positive.
A farm in Wright County with 1 million chickens has experienced increased deaths among the flock and a preliminary test indicates the presence of the bird flu virus.
The frequency of new cases has slowed dramatically with no new cases in Minnesota in 11 days. Iowa’s last reported case was June 9. The bird flu has cost Minnesota, the leading turkey producer, 9 million birds. Egg farms in Iowa, the nation’s leading producer, have lost over 25 million laying hens.
State officials say all 76 previously affected farms have removed the 32 million birds that already died or were euthanized. Disposal of the dead birds continues.

Thousands of dead fish found in a river in Sarcedo, Italy

Fish Kill Alert

Thousands of dead fish floated on the river while waters was a rancid stench, the situation reported by fishermen along the Astico on weekends.
As reported in the paper version of Il Giornale di Vicenza, sanguinerole, Chub, barbel, Grayling and trout, were rapidly rotting because of the heat below deck of Sarcedo, where the bed is now reduced to a puddle.“
Beached carcasses attracted in mice and birds with many risks to public health. Only the heavy rains on Sunday resolved the situation, sweeping away all the bodies. A problem that for many could be avoided. One of the possible causes of the deaths of fish, in fact, is the gradual closure of the canals that feed the Astico agreement. The consortium of reclamation “high plain veneta” that organizes water management, had enabled the volunteers of certain non-profit associations, providing several recoveries before the fish dry. Just last Friday night shortly before the discovery of carcasses. According to the associations, it would be impossible for thousands of fish have been left behind.“

Dozens of giant purple sea slugs washing ashore in Alameda, California, USA

An invasion of giant purple slugs are washing ashore in the East Bay, populating beaches and waterways.
Experts say the high volume of these slugs may be caused by warmer temperatures near coastal waters.
The slugs themselves are harmless herbivores, but their enormous size and slimy abundance is disturbing beach-goers.
“We are getting calls from the public asking what the heck is this big weird purple blob,” said Carolyn Jones, a spokeswoman for the East Bay Regional Park District. “It’s native to our area. It’s not endangered, but they are rarely seen other than an occasional one here or there.”
While the quantity of washed-up slugs hasn’t been enumerated, dozens at a time have been seen on the shores.  The slugs were also spotted last month in an inlet leading to Lake Merritt.
The slugs can grow to be up to 15 pounds, and more than 30 inches in length, according to officials.
Morgan Dill, a naturalist at the Crab Cove Visitor Center in Alameda. “We can’t say for sure why we’re seeing so many, but the Bay temperatures are definitely warmer this year,” Dill told AP.
In Oakland, local resident Joel Peter said “I had never seen one before, and then all of a sudden there were 22 of them with these brilliant colors,” Peter said. “They really caught my eye.”

Massive die off of fish in ponds right across Leizhou in China

Fish Kill Alert

“Leizhou rain hadn’t played so far this year. “According to reporter investigates drought in leizhou region this year unusually severe, one of the largest reservoirs of leizhou in Longmen reservoir has nearly dried up since May, started to advance into the hot season of leizhou, average temperatures of 30 degrees or more.
Due to the extreme weather, in late May, leizhou culture of Tilapia began dead fish; up to now, the whole area of leizhou 80%-90% tilapia ponds has killed the fish, some pond fish very seriously, or even destroyed, an average weight of 0.6-1 kg/piece. See reporter visited, most aquaculture of Tilapia fish carcasses pile up, far away could smell pervading stench.
“Dead fish every day since late May, my fish ponds has killed 230,000 pounds of Tilapia. “Leizhou Fu cheng Zhen Chen farmers told reporters that he had more than 400 acres of Tilapia ponds, dropping seedling began last September, average weight of Tilapia at about 1 kg/piece, that tilapia price slump, caused him to delay the fish, but due to serious disease, he had to start out fish. “Some say Streptococcus, but previous tilapia disease drug effects, this year had no effect, can not suppress the dead fish, do not know why, tilapia disease a month earlier than usual this year. ”
Leizhou has 340,000 acres of Tilapia aquaculture water, feed market capacity is 50,000 tons, is at the heart of Tilapia in Zhanjiang region. Local fish polyculture model, 2-3 made of fish a year, 2 years 5 fish farming model, on qingming fish. However, since the end of March this year, tilapia prices have plummeted, and 0.6-1 kg/piece of Tilapia prices now in 2.8-2.4 Yuan/kg, fall into the bottom of history; one more than years of 2 fish in leizhou region farmers pressing Tong Ji fish for sale, the selling price, deposit large amount of Tang.
Hairong feeds Ltd Zhanjiang in Zhanjiang area manager Huang Gaocheng, leizhou dead fish is mainly in the area of the weather, because the water temperature is too high, lack of fresh water added, so in the high temperature environment of Tilapia will definitely lead to problems, an outbreak of Streptococcus is the easiest at high temperatures. Tilapia is unique in Zhanjiang area this year, depressed prices, drought and water shortage and continuous high temperature, multiple negative factors leading to the bottom. But he believes that the fish is not the most serious cases, prices are low is the fatal blow, because, according to current prices, most farmers are losing money.

Thousands of dead fish in another fish kill on Peconic River in New York, USA

As the Peconic River teems with thousands of dead fish after another bunker kill, town and county officials are struggling to find solutions to deal with the clean-up – and the stench.
“It’s totally disgusting,” said Joanne Tyte, who lives on Howell Lane on the Peconic River. “The smell is so bad that we can’t even go outside.”
Last month’s major fish kill washed up tens of thousands of dead bunker on shores from the Peconic River to the Peconic Bay after algal blooms starved the water – and its bunker fish – of oxygen. And last weekend, oxygen levels in the Peconic River once again dropped very low due to another algal bloom, triggering yet another fish kill.
Fortunately, this weekend’s kill appears to be smaller than last month’s, but it has washed up thousands more stinky dead fish near the homes of fish-weary residents who are still reeling from the remains of the last kill.
“Since June 7, we’ve had nothing but southerly winds, and that’s just been carrying that smell to our house,” said Jennifer Parillo, who lives on Riverside Drive. “It just hasn’t stopped. It keeps on coming.
“I don’t think you can count on the wind blowing to clean up this mess,” she added.
But for the moment, local officials are having a difficult time finding a better solution.

The sheer volume of dead fish that has washed up in marshland, which is inaccessible to nets, as well as on private property, where the town cannot trespass to remove the fish, has made cleanup “extremely difficult,” Town Supervisor Sean Walter says.
“There’s just not enough manpower in Riverhead to take care of this,” Walter said. “We’re doing everything we can to keep the public areas as clean as possible, but a lot of this is private property. Even if we had the manpower, we couldn’t go onto those properties.”
He pointed out the difficulty of cleaning out a private marina where dead fish tend to build up and sit in the stagnant water, such as the marina at the Moose Lodge. “We would need to take every single boat out of there to get those fish,” he said. “I don’t think that’s even possible.”
Marshy areas where the fish get caught in reeds and grasses pose another challenge. “There’s no way to remove those fish except by hand,” said Suffolk County Legislator Al Krupski.
Many of those marshy areas are also “environmentally sensitive,” Walter said. “You’d be doing more harm disturbing those areas than the good you’d be getting out of removing the fish,” he said.
And then there’s the question of what to do with the fish once they’re out of the water. Residents who bag dead fish from their private properties can call the town for pick-up. The town then transports the bagged fish to a disposal facility in Brookhaven, where the town is paying a premium to get rid of the smelly fish.
As for the fish the town removes itself with netting in the river, the town is currently working with the New York State Department of Environmental Conservation to find a place for them.
Krupski says he contacted the Long Island Farm Bureau to see about using the dead fish as fertilizer on local farms, which was a regular farming practice on Long Island in the 1800s.
But Walter is not fond of that solution. “We don’t want to put that smell in someone’s neighborhood,” he said. “In the 2009 kill, the town thought that was a good idea. But the stench in the neighborhood was unbearable.”
Large bunker kills are not unusual in the Peconic River, but they are usually a result of bluefish, bunker’s natural predator, chasing them into shallow, low-oxygen waters. This past weekend’s kill and the widespread fish kill in late May, however, were both caused by unusually high densities of algal blooms, which strip the water of its oxygen and leave very little for the large schools of bunker fish that have been dying off as a result.
Algal blooms have been measured this year at unprecedented levels in the Peconic River, Peconic Bay and Flanders Bay, according to Christopher Gobler, a Stony Brook University research professor who studies the Peconic estuary through the Long Island Coastal Conservation Research Alliance.
And as additional rainfall washes more nutrients into the water, which ultimately intensifies the algal blooms, more fish die-offs will remain a possibility throughout the season, he said.
“As long as large bunker schools persist, the threat remains, as the low oxygen levels and algal blooms will likely continue,” Gobler said.

23,500 birds killed due to new outbreak of avian flu in Taiwan, China

Bird Flu

Three more outbreaks of highly pathogenic avian influenza have been confirmed in Taiwan.
The outbreaks were of the H5N2 serotype and occurred in the western county of Yunlin.
There were 8894 cases in a susceptible population of 23528 birds, including two geese farms and one chicken farm. All the affected birds died, and the remaining susceptible birds were destroyed as a precaution.
These farms have been put under movement restriction, and thorough cleaning and disinfection have been conducted after the stamping out operation. Surrounding poultry farms within 3 km radius of the infected farms are under intensified surveillance for 3 months.

And called on the Government to intervene and the announcement put financial compensation for farm owners that may become infected and thus execute, so plantation owners are encouraged to report any injury or symptoms.

New eruption at Cleveland Volcano in Alaska

Cleveland volcano satellite image by (c) Google Earth View
The Alaska Volcano Observatory detected that a new (so far minor) eruptive episode has started at the volcano recently:
“Elevated surface temperatures have been detected in satellite images at the summit of Cleveland for the past week, and an image from June 14 shows very light ash cover on the volcano’s upper flanks. Thus the volcano has entered a renewed period of unrest and we are raising the Color Code to Yellow and the Alert Level to Advisory. 
The increase in temperature at the summit is consistent with renewed growth of the small lava dome within the summit crater. The possibility of sudden explosions has increased.”
