Mass die off of fish in a lake in Nanning, China



Hundreds of TONNES of fish have died due to virus in West Java, Indonesia

Fish Kill Alert

Pembubidadaya fish floating net (KJA) Jatiluhur, Purwakarta, West Java, panic-stricken. Because, lately attack koi herpes virus (KHV) began raged. As a result of the virus attack, carrying 217 tons of dead fish.

In anticipation of greater losses, farmers are forced to harvest early. Chairman of the Association of Farmers and Fishermen Fish (Hipni) Jatiluhur, Dervish, say, along the pond in 2014 Jatiluhur have several times attacked by the virus. The most severe at the end of last October until now. As a result of the virus, dead fish one by one.

“The fish are dead since the end of October to date has reached 217 tons,” said the Dervish, Monday (3/11).

Disclosed, the potential death of these fish, big enough. Given that, until now the fish farmers can not break the chain of the virus. Thus, of the loss is too great to bear, it’s better early crop farmers.

However, he continued, the impact of this early harvest, production declined 20 percent. Dervish

He explained that, when normal conditions, in a population of fish cages reached 10 thousand heads, when the harvest could produce 1.5 ton.Namun, with early harvest, the results obtained by the farmers only 80 percent. “So, farmers lose the fish reaches 20 percent due to the herpes virus attacks,” he added.

Worse yet, he continued, the price of fish is currently falling. In the market, carp price is only Rp 14 thousand. Ideally, more than Rp 16 thousand per kilogram.

The cause of this herpes virus, Dervish suspect, due to extreme weather. Hot weather like today, thought to be the trigger for this virus thrives. Thus, the virus that has no cure is to freely attack the goldfish is being cultivated.

Head of the Department of Animal Husbandry and Fisheries Purwakarta Herawan Herrera, admitted, fish herpes virus was still safe for consumption. Thus, the virus will not attack humans. By doing so, it appealed to people not to negative view of the case against the herpes virus attacks the fish in Jatiluhur.

Thousands of dead fish appearing in various parts of Spain and Mexico

Hundreds of fish found dead in Spain and Mexico – A strange phenomenon is common these days in Spain and Mexico. The presence of thousands of dead fish in Seville, Valencia and Veracruz. Were found in the last hours by residents in the area of the basin of La Marciega, Seville, in Lake La Devesa del Saler, in Valencia, Spain, and in the lagoon El Paraiso in Veracruz, Mexico, died in large numbers for reasons unexplained and stacked on the banks. according to experts at the origin of the death of so many fish in two different places of the world there may be a sudden change in climate, in this case a rapid change of temperature at which the fish would not be able to get used to and that would leave them without oxygen.

Another reason could be linked to the fact that the intense heat of the last days would have caused a high evaporation, leading to the death of many fish. In any case, the fish were removed from the three laghie will proceed to a thorough analysis of the water, to see if there have been poured potentially harmful substances. Also because, in the case of the lagoon of Veracruz in Mexico, is not the first time that such an episode occurs.

135 sea lions, 2 whales, 4 turtles, 5 dolphins and pelicans wash ashore dead in Sechura, Peru

Sea lions and whales beaching in Piura beaches continue

A new varazón of 187 sea lions and an unspecified number of whales occurred yesterday on the beaches of San Pedro and San Pablo, La Islilla and La Tortuga, in the provinces of Paita and Sechura, reported local fishermen. The finding adds to the varazón, last week, of 135 sea lions in the reserved area of Illescas.

Carlos Yaipén , director of the Scientific Organization for Conservation of Aquatic Animals (ORCA), told this newspaper that a team has monitored his recent appearances of dead animals across the northern coast, from Tumbes to La Libertad. After several weeks concluded that aquatic animals were killed by artisanal fishermen.

“The death of whales it is for the season, there is much traffic these species. We have also discovered poisoned animals. Illescas However, we found that artisanal fishermen have killed Sechura sea lions, “he said.

In this regard, sources Instituto del Mar del Peru (IMARPE) confirmed investigating the cause of death of hundreds of sea lions and other species in the northern coast. Note that in 2012 most varazón of aquatic animals was recorded: from Tumbes to Lambayeque over 760 dead dolphins were reported.

Thousands of dead fish found floating in a river in Rokan Hulu, Indonesia

Allegedly Due MCC Waste, Dead Fish in the River Estuary Nails, Rohul

Thousands of dead fish floating in the various types of River Estuary Nails, District Fullness on Friday (10.31.14). Natural phenomena shocking villagers West Fullness Noble, Rokan Hulu (Rohul) around 08.00 pm.

Been known to cause thousands of dead fish in the river estuary Nails, including a lizard. However, local residents suspect a waste of one of the mills (MCC) in the upstream which pollute local rivers.

Find many dead fish, citizens and residents Noble West Fullness Fullness West Village, on Friday morning to evening picking up dead fish follow. Even up to bring jute and bucket as its place.

Most people acknowledge the fish died suddenly it will be consumed. However, for other people, they are watching. Fear of things happen that are not desirable.

Residents admitted River Estuary Nail they used for bathing, washing and clean water source. Boarding School Nizammudin also commonly utilize the flow of water sources.

“Since Friday morning, the river water can no longer be used by the citizens,” said Karman, Friday night.

Meanwhile, Chief Boarding Nizammudin H Zulkifli Said told reporters confirmed that the death of thousands of fish in the river estuary Nails stunned.

Admittedly, the color of the river water has been changed and cause the smell of sewage. The students did not dare to use the water for the activity. Whereas in a normal day, the river was also used for washing the motorcycle community.

Zulkifli revealed he has banned the students in order to temporarily not use the river water to move. However, using well water in their Ponpes.

To reporters, some residents admitted officers from the local village government and the company has come down to a location to take a sample of water that has been colored blackish Nails victimization in the River Estuary.

Separately, Head of the Environment Agency (BLH) Rohul June Syafri through the Head of Development and Resources EIA Hasjal Zakri said MCC operates in the Fullness of West Noble is owned by PT. Sawita era.

Zakri acknowledge Sawita Era MCC has pocketed permission Environmental Monitoring (UPL) and Environmental Management Effort (UKL). However, he did not confirm whether the two documents have been executed better permit or not.

Admittedly, the clerk of BLH Rohul has come down to the field to take a sample of suspected contaminated river water.

Millions of birds have died due to storms in Visakhapatnam, India

The cost of chicken and eggs is going through the roof in the city, thanks to the damage suffered by the poultry industry due to the cyclone Hudhud. With the industry not showing any signs of immediate revival, prices are likely to soar further.

As on date, chicken is priced at 180 rupees a kg as against its normal price of 140 rupees, with meat shop owners predicting that the cost would reach 200 rupees in the coming days. Similarly, eggs are being sold for ‘six each as against ‘four and are likely to touch ‘seven, reports TheNewIndianExpress.

In the districts of Visakhapatnam, Srikakulam and Vizianagaram, there used to be about seven million broiler chicken, a whopping 60 per cent of which died due to the cyclone, causing immense damage to poultry farms.

As a result, only a small quantity of broiler chicken is arriving into the market. The city itself requires 150 tonnes of broiler chicken per day. As there is no chicken available in the district, it is being brought from Godavari districts, thereby causing scarcity there.

“At this rate, the price is sure to go up further. It may even go beyond ‘200 per kg,” says Mohammed Arif, a meat vendor at Isukathota Junction. Since the remaining broiler chicken in the city might cause health problems, as the birds have been affected by the storm, the demand for country chicken has risen sharply, leading to an increase in price from ‘300 to 360, which is likely to go up as well.

The same is the case with layers. In Vizianagaram and Visakhapatnam, around 1.65 million birds died in the cyclone. On normal days, one hundred thousand birds lay 85,000 eggs. “But with so many birds dying, it would be a miracle if we get at least 20,000 eggs,” said NECC zonal chairman (Visakhapatnam) G Ramakrishna Chowdhary. In the coming winter, the cost of eggs is likely to rise steeply as the demand would peak in West Bengal and other north eastern states, he said.

Millions of dead fish appear in a river in South Kalimantan, Indonesia

Jutaan ikan mati cemari Sungai Riam Kanan

Millions of fish that died because of lack of oxygen causes the Riam Kanan River in South Kalimantan Banjar district contaminated with bacteria from fish carcasses.

“The river must have been contaminated due to the millions of fish carcasses fills the entire body of the river,” said Saifuddin, the owner of floating net cages in Martapura Bangkal Awang village on Monday.

Owner another floating cages Burhan said, millions of carcasses tilapia and pomfret meet Riam Kanan river flow which has a width of 30 meters and a length of seven kilometers.

Mentioned, streams filled with fish carcasses will become longer if the flow of runoff water running when the door is opened the water reservoir Riam Kanan so widespread pollution.

“The flow of the river along the new seven kilometers from village to village Tambela Awang Bangkal, later when the water flows, fish carcasses will be carried downstream,” he said.

According to him, the owner may not dispose of the carcass cage fish ashore or buried because the very large so that the only way to throw into the river.

Described, the condition of the river is very horrible because carcasses filled with millions of fish that can not be used meet the daily needs such as bathing and other.

“Never bathe, wash hands just not possible because the river met the fish carcasses and smells so anyone should cover the nose,” he said.

It is said, the death of hundreds of tons of food fish are harvested and the seeds that make hundreds of floating cages owners have lost billions of dollars.

“Every farmer average loss of hundreds of millions for dead fish weighing several tons so if multiplied by the loss of hundreds of billions of fish farmers,” he said.

Secretary of the Department of Marine and Fisheries Kalsel Mariatul Ayesha met the owner cages, Monday afternoon, said he asked for the complete data related to the problem.

“We asked for a good number of complete data owner cages, the number of dead fish and other data that can be retrieved quickly troubleshooting steps,” he said.

Mass die off of sea stars now happening in Sitka, Alaska, America

A trip to the coast usually means you’re going to see sea stars, but a mysterious disease is killing them along the West Coast. There had been a few reports of sick sea stars in Alaska, but recently in Sitka, the first mass die offs in the state were detected. Scientists in Sitka are tracking the progress.

Patty Dick lives on a boat in Thompson Harbor in Sitka. In the morning, when it’s low tide and she has an extra moment, she goes out and checks on the sea stars living in the area.

“I just sit there in awe of the beauty of that animal,” she said. “Everybody loves sea stars.”

Dick teaches 6th grade biology at Blatchley Middle School. She often takes her students on field trips to learn about marine animals, and they usually find dozens of sea stars.

But one morning last month, Dick noticed something was wrong with the sea stars. “I just looked over and I just stopped. There were these big, huge, white spots all over them and they were just wasting away. My heart just sank.”

She’d heard about this happening, but she hadn’t seen it with her own eyes. “I’m trying to find one star fish that is not affected,” she said, “and they were all dead. They were all dead.”

They had sea star wasting disease. All along the West Coast, sea stars have been dying of this disease. The first case was discovered in the summer of 2013 on the Olympic Peninsula and scientists still don’t know what’s causing it.

Taylor White is the aquarium manager at the Sitka Sound Science Center. For the past year, she’s been working with a team that is monitoring sea stars and other marine life in Sitka and along the West Coast.

“You really do look a lot harder at sea stars now that sea star wasting disease is occurring. I feel like a lot of people are paying a lot more attention now.”

“It’s a lot of just crouching down and going from the top left corner and going through the entire plot, moving this rockweed around, and counting as any starfish as you see,” White said.

She takes me for a walk along the beach to see for myself. She pulls up a rock and is looking at some six-legged sea stars called leptasterias. We’re looking at sea stars on Sage Beach, next to the science center.

The Sitka Sound Science Center is part of a project called MARINe, which stands for Multi-Agency Rocky Intertidal Network. MARINe is made up of agencies that use the same marine monitoring methods. They’ve set up about 120 sites along the coast in the U.S., from Southern California to Alaska. There are three sites in Sitka – the only long-term MARINe sites in Alaska. White helps monitor the Sitka sites as part of her job at the science center.

“You really do look a lot harder at sea stars now that sea star wasting disease is occurring,” she said. “I feel like a lot of people are paying a lot more attention now.”

Once sea star wasting hits an area, it can quickly spread through the population. Research divers from the University of Alaska, Sitka, have surveyed different areas in Sitka Sound and have seen evidence of wasting in most locations. At Sage Beach, divers found that in the past few weeks, sunflower stars have disappeared, leaving behind white ‘ghost piles’ of tissue.

While there have been minor wasting events in the past, this event is by far the longest and most widespread.

White says she’s seeing the same thing happen in the touch tanks at the Sitka Sound Science Center. “A lot of those guys have been in there for a very long time. It was hard to see it suddenly hit.”

They use an open system, so sea stars live in water straight from the ocean. She describes what she saw when the disease hit. “They just started crawling away from their bodies,” she said. “They contort themselves. Then they just started to decay since there are so many bacteria in the water. They just kind of break down after that point.”

When sea stars are sick, they can lose a leg and then regrow a healthy one. But with the wasting disease, they just keep losing legs, sometimes until only a central disk is left. The aquarium has had 35 sea stars die within three weeks, and now, only two remain in the touch tanks.

Scientists know there will be substantial impacts from these mass deaths, but they aren’t sure what yet.

Marnie Chapman, a biology professor at the University of Alaska, Sitka, has been working with White in the longterm monitoring project. She says sea stars play a big role in the ecosystem.

“They are major predators in the intertidal,” she said. “They’re definitely the lions and tigers of the intertidal environment.”

And they’re diverse. There are about 1900 species of sea stars in the world, and at least 18 in Sitka alone. “Sea stars are as unique and as individual than those predators that we’re more familiar with,” said Chapman.

There are several groups trying to figure out what’s causing this mass die off. It could be a bacterium, a virus, or environmental change, like lower pH levels in the ocean or warmer water. Most scientists think it’s a combination of things.

“They just started crawling away from their bodies. They contort themselves. Then they just started to decay since there are so many bacteria in the water. They just kind of break down after that point.”

When scientists do figure it out, there’s not much that can be done. If it’s a pathogen, there won’t be a sea star vaccine. If it’s warmer water, that’s irreversible.

Chapman worries about the future of the species. She recalls a day when she was out counting dying sea stars and a boy was looking at healthy ones nearby. “This young kiddo was saying, ‘mom, look at all the sea stars,’ and there were a lot of really healthy, unaffected on the side they were looking on,” she said, “and I thought, ‘boy, I hope that still happens. I hope that still happens next summer.’”

But there is some hope. At some of the MARINe sites along the coast, they’re seeing some juvenile sea stars. So, they could make a comeback. In time, we’ll know better.

And there is something that everyone can do to help track the disease. If you see sick or healthy sea stars, report it to seastarwasting…org. Reports from the public help scientists better understand the disease and could help solve this mystery.

Hundreds of thousands of TONNES of shrimp wiped out due to disease in Thailand

Shrimp exports are not expected to recover until next year’s second quarter, as Thailand has yet to eliminate early mortality syndrome (EMS) from its shrimp farms. “Overall shrimp exports remain in bad shape.

Thousands of fish die in a lake in Dexter, New Mexico, America

Fish Kill Alert

Hundreds of fish are dying at a New Mexico lake, and now, people who have caught some of those fish are wondering if they could get sick, or even die.

Rotting fish are everywhere at Lake Van in Dexter.

“The more I look, there’s thousands and thousands of fish just floating to the top, and now the stench is getting really bad; there’s flies everywhere,” said Colleen Cole-Velasquez.

Velasquez lives on the lake.  She says the smell from the rotting fish is getting into her home.

“When the smell crosses the road over to your property, that’s not exactly what you want to smell when you’re getting ready for dinner,” said Cole-Velasquez.

Walk up to any bank on the lake outside of Roswell and you will see dozens of dead fish.

“People should be worried,” said Game and Fish Biologist Shawn Denny. “When you see something dying in your environment, that should set off an alarm bell for you.”

Denny says the reason for the die-off is a microscopic plankton called golden algae. Denny says since last Monday, the algae have wiped out 95 percent of the fish in the lake.

Now there’s a whole lot of rotting fish, flies and questions.

“You see a lot of fish floating to the top, and of course it makes you concerned living on the lake,” said Cole-Velasquez. “Is this something that could harm me? Is this something that could harm our pets?”

Game and Fish says yes, and that you should avoid sick fish.

“We tell people, ‘do not pick up any sick or dying fish and eat them, period,'” said Denny.

But Cole-Velasquez says he wonders how you know if they’re sick and why there aren’t any signs.

“How do you know if a fish is sick? It’s not going to cough at you, you know. You can’t take its temperature,” said Cole-Velasquez.

The lake is still open to the public, but Game and Fish says to use caution until this algae is gone.

“We do ask people if you are going to fish in this lake, if you’re going to boat in this lake, to clean all of your equipment,” said Denny. “Let it dry out significantly before you go to another water body.”

The last golden algae kill was in 2010. Game and Fish says it will re-stock the lake when the bloom is over.
