In the afternoon of 10-8, dozens of fish farmers under Cha Sa bridge (Long Son commune, Vung Tau city ) have come to Ba Ria – Vung Tau People’s Committee to meet with Chairman of the Provincial People’s Committee Nguyen Van Truong to present the fish Died abnormally on the Cha River in the past days. However, because the chairman of the provincial People’s Committee is working, the households have not met.
Previously, as reflected by fish farmers in Long Son commune, about a week ago, the phenomenon of dead fish scattered all over the cage makes them stand still.
Mr Nguyen Cong Bien, a fish farmer, said: “Fish do not show signs of disease but are lethargic, stop eating and die abnormally. This phenomenon occurs in most cages, “We are very interested in the cause of this condition after the authorities have taken samples.”
In the afternoon of the same day, the Department of Agriculture and Rural Development of Ba Ria – Vung Tau province reported on the incident.
According to reports, as of the end of 9-8, about 241,000 fish, estimated at nearly 90 tons, died in the last. There are 23 households where the fish died, of which 11 new fish stocked fish a few days, the fish have matured 3-4 months. Of these, 9 households have the highest mortality (10,000 to 25,000).
After receiving the news, the Department of Agriculture and Rural Development has sampled fish, water samples for testing. The results showed that none of the samples infected the virus causing necrotic necrosis on saltwater and brackish water fish. Fish specimens also have the appearance of Vibrio spp. Water samples all have COD and NH3 levels that exceed the allowable limit.
At the time of the dead fish, sewer No. 6 in Tan Hai Commune (discharge culvert causing mass mortalities in 2015) was sealed, there was no discharge, Due to the rain, it should reduce salinity as well as oxygen content in water. In addition, the amount of dense fish also hinders the flow of water.
Analysis of water samples shows that there is local pollution in the culture area, there are some causes leading to such situation as domestic wastewater of households in the area, the amount of excess food. After the dead fish, people do not handle the process that the phenomenon of throwing fish in the river makes the water environment more polluted, the fish die more.
Also from the reflection of the people, functional forces have discovered the business Ngoc Viet (trading in materials for floating raft aquaculture) discharge waste water rinse plastic barrels, labels outside Records containing some chemicals, near the dead fish should be seized and analysis of wastewater samples.
Ba Ria – Vung Tau Department of Agriculture and Rural Development asked local households and local authorities to mobilize people to harvest fish to reach the size to reduce the damage and stop the stocking to improve the water environment. At the same time, find out the main cause of death.

A dead great shearwater recently found on a Block Island beach. (Matt Schenck)
Walking on the beach at the north end of Block Island last month, Matt Schenck stumbled upon two dead and decomposing seabirds, which the avid birdwatcher identified as great shearwaters. While gulls of various species are commonly found dead on local beaches, shearwaters are an extreme rarity.
Except this year
Hundreds of great shearwaters have turned up dead on beaches on Long Island and southern New England this summer, and no one seems to know why. In addition to the birds on Block Island, birders and biologists have reported dead shearwaters on Rhode Island beaches in Tiverton and Charlestown.
Shearwaters spend most of their lives far out to sea, where they soar just above the waves as they forage on small fish and other marine creatures near the surface of the water. Four species of shearwater — great, sooty, Cory’s and Manx — are typically seen in Rhode Island waters, though they seldom travel within sight of land. Most breed on remote islands in the South Atlantic.
According to Josh Beuth, a biologist for the Rhode Island Department of Environmental Management, shearwaters have been observed in large numbers from the shore this year, including from Jamestown, Newport and Point Judith. They have also been seen regularly from the Block Island ferry.
“There has been an abundance of sand eels in our local waters, which are a forage fish for shearwaters,” Beuth said. “As a result of them being closer to shore than usual, it would be more likely that they’d wash up on shore if they died.”
While prey may be abundant, some biologists, including Linda Welch, a U.S. Fish & Wildlife Service biologist who studies great shearwaters off Cape Cod, have noted that many of the dead birds are juveniles that have been thin or emaciated, suggesting that the birds have starved.
The dead birds began to show up on beaches in late June, which is about when they should have arrived along the East Coast after their long migration from their breeding grounds in the South Atlantic. By then, they were likely stressed and tired and hungry, which may have made them susceptible to any number of potential sources of mortality.
Wildlife pathologist Joe Okoniewski examined some of the dead shearwaters found on Long Island beaches, and he told The New York Times that the birds were not only thin but anemic. “The big mystery is: Why are they thin? On the surface, it looks like you know what happened — they starved,” he said. “But when you ask why, it becomes much more of a mystery.”
It is especially mysterious if prey is seemingly abundant, as it has been this summer in Rhode Island waters.
Robert Kenney, an oceanographer at the University of Rhode Island’s Graduate School of Oceanography, speculates that toxic algae from red tides may be playing a role in the bird deaths. He said a number of northern gannets, another species of seabird, have been found dead on Cape Cod beaches this summer. The only difference, he said, is that they are “in good condition, except for being dead.”
He noted that toxic algae may have also contributed to the deaths of some of the numerous whales that have been found dead along the East Coast and in the Gulf of Saint Lawrence this year.
Among those trying to find an answer is Julie Ellis, director of the Seabird Ecological Assessment Network at the Tufts University Veterinary Medical Center, which uses volunteers throughout the Northeast to regularly walk beaches to collect dead birds for study. She is reaching out to a number of animal diagnosticians throughout the region in hopes that together they can come up with a consensus of what is causing the shearwater deaths. She hopes they will have an answer next month.

The carcass of a North Atlantic right whale is seen off of Edgartown, Mass. in Martha’s Vineyard – National Oceanic and Atmospheric Administration
A 12th North Atlantic right whale has been found dead, this time in Martha’s Vineyard in Massachusetts, according to National Oceanic and Atmospheric Administration (NOAA) Fisheries.
In an interview with Global News, NOAA Fisheries Greater Atlantic Region spokesperson Jennifer Goebel said the whale was found Tuesday floating off of Edgartown. She said the Martha’s Vineyard Land Bank Commission sent photos to NOAA Fisheries which confirmed it was a North Atlantic right whale.
The International Fund for Animal Welfare, located on Cape Cod, Mass., is performing a necropsy Wednesday to determine what caused the death of another endangered right whale. Goebel added that it would not take place on a public beach in the area, but would not say where due to privacy reasons.
Through the photos provided by the commission, Goebel said they were able to confirm it was a right whale.
As of last Thursday, the Department of Fisheries and Oceans said it would bring all resources necessary to protect the right whales after 10 had died in the Gulf of St. Lawrence.
Earlier this spring, Goebel said there was also a right whale that died after being stranded in Cape Cod. In an email, she said final results of the necropsy report have not been received but the initial analysis was the death was due to the whale being struck by a vessel.
DFO Minister Dominic LeBlanc said last week it’s believed 80 to 100 right whales are currently in the gulf and the DFO says in total, there are approximately only 525 right whales in the world.
Various precautions have also been taken as a result of the deaths, including asking mariners to slow their ships to 10 knots when passing through the areas and limiting the amount of rope they have on the water. LeBlanc said collisions with ships and fishing gear entanglements are major threats to the whales.
During one entanglement last month, however, a veteran fisherman from Campobello, N.B. was killed while freeing a whale.
This incident prompted Canada and the United States to temporarily suspend efforts to rescue entangled whales.

Scores of convulsing sea lions are washing up on Central California beaches after eating fish poisoned by a plume of toxic algae that could spread north toward the Bay Area and cause widespread problems, marine biologists said.
Since June, veterinarians at the Marine Mammal Center in the Marin Headlands have treated 89 animals — all but seven of them sea lions — plucked mostly off beaches near San Luis Obispo, where a large algal bloom formed in the ocean.
Of the 82 sea lions brought to the center, 31 have died, and virtually all of them had seizures caused by domoic acid, the dreaded neurotoxin that closed down the Dungeness crab season two years ago and killed off thousands of marine species over the past two decades, said Shawn Johnson, the center’s director of veterinary science.
“We’ve rescued 64 animals just in July,” said Johnson, who coordinates the rehabilitation of injured marine mammals rescued from San Luis Obispo to the Oregon border. “They’ve been coming in huge waves, as many as 10 a day.”
The coming crab season, which typically kicks off in November, is not currently being threatened, but state health officials are monitoring the situation to see if algal blooms begin cropping up farther north as ocean temperatures climb in the late summer and fall.
The stakes are high for the environment and for the fishing industry. More than 21 million pounds of Dungeness worth $66.7 million were pulled in during the 2016-17 season, the best haul in four years and almost double what was taken a year earlier when much of the California coast was blanketed in algae, prompting fishing restrictions and health warnings.
The latest bloom, known as a red tide, appears to be on a northward trajectory. Starting in April, dozens of sick and dying sea lions, dolphins and fur seals were found on beaches in the Los Angeles and San Diego areas.
Over the past two months, most of the poisoned sea lions, fur seals and sea otters have been washing up on beaches around Oceano Dunes State Vehicular Recreation Area in San Luis Obispo County, Johnson said. Many of the rescued sea lions were lactating females that had been foraging near the Channel Islands for food to feed their pups.
“To have them so concentrated in such a short time period is unusual. That tells us there is a really toxic bloom of algae in that area,” Johnson said. “As the water temperatures increase over the summer, we see this bloom migrating farther north, so it’s possible we could see it reach the Monterey Bay area in the late summer and fall.”
Outbreaks like this one have been sickening increasing numbers of marine mammals since the first toxic bloom was documented on the West Coast in 1998, when 400 sea lions washed ashore in Monterey Bay.
The culprit was a microscopic, single-celled species known as pseudo-nitzschia, which produces domoic acid. The algae grows thicker and faster in warmer, nutrient rich seawater, and the toxin it produces accumulates in shellfish, mussels, anchovies, sardines and herring, the primary food of sea lions.
When it is sufficiently dense, it attacks the hippocampus, the brain’s memory center, and can cause memory loss, tremors, convulsions and death. The toxin, which accumulates in the bloodstream, can also sicken people who eat fish, crab or mollusks.

In the Cherkassy region for an unknown reason, there was a massive sea of fish. This is reported by the local television channel “Wicca”, with reference to the publication “Dash.” The bodies of the fish are completely settled by the coast within the villages of Vasyutintsy, Veremeevka and Pridneprovskaya.
And all livestock was lost – regardless of size and species. At the same time, as the peasants are worried, it stinks incredibly. People do not see objective reasons for mass fish moraine. While in the profile department of the State Environmental Inspection on the current situation traditionally do not know anything, although they promised to study it in the near future.

Zimbabwe and South Africa have lost over one million chickens to Highly Pathogenic Avian Influenza (HPAI), it has been learnt.
The disease hit the two countries recently, threatening the livelihood and food security status of millions of families.
The Food and Agriculture Organisation (FAO) confirmed the development in a statement after a SADC meeting on avian influenza in South Africa.
FAO said if not tackled quickly, the HPAI outbreak would impede trade opportunities and reverse the gains made in enhancing food and nutrition security.
SADC representative, Mr Bentry Chaura, said South Africa had so far culled over 800 000 birds.
Zimbabwe culled around 215 000 birds.
“This is likely to have a knock on effect on the availability of table eggs and poultry meat for consumers in the region. South Africa alone is destroying one million eggs a day from the affected farms. Small-scale producers are also expected to face shortages of day old chicks in the market,” he said.
Mr Chaura said the bird flu had come at a time when the region was struggling to recover from the El Niño-induced food shortages (2015-2016 season) further worsened by the emergence of other pests such as the fall armyworm which devastated crops this year.
“We are all witnesses of what animal diseases and pests, particularly transboundary animal diseases, can do to worsen the vulnerability of rural-based communities.
“Those do not only affect lives in the community, but also normally have a lasting impact on local, regional and international trade,” he said.
In Southern Africa, the flu has so far been reported in the Democratic Republic of the Congo, South Africa and Zimbabwe.
In South Africa and Zimbabwe, the disease has mainly been identified on large commercial farms, where systems to monitor outbreaks are readily in place compared to smallholder and backyard producers.
The spectre of bird flu outbreaks has been looming across the region since the beginning of the year when Uganda reported an outbreak (January 2017) prompting SADC member states to develop the capacity for surveillance, detection, prevention, and rapid response to HPAI.

Animals died in a farm in Ribas do Rio Pardo and the suspicion is of intoxication by bacteria that causes botulism (Photo: Marca 7 / Divulgação)
The State Agency for Animal and Plant Health Protection of Mato Grosso do Sul (Iagro) is investigating the death of 1.1 thousand head of cattle in the confinement of Marci 7 Pecuária, at the Monica Cristina farm, in the municipality of Ribas do Rio Pardo, at About 40 kilometers from Campo Grande. As the animals were practically ready for slaughter, the estimate is that the death caused a loss of approximately R $ 2 million to the breeder Persio Ailton Tosi.
Iago CEO Luciano Chiochetta told the G1 that the killings began on Wednesday (2) and that on Friday (4) the owner informed the agency that he sent a team to the scene. The suspect, he says, is from botulinum toxin poisoning, which would have occurred when the animals ate moist corn silage, which was stunted.
The clinical suspicion of botulism, according to Chiochetta, is based on the symptoms that the animals presented when they were dying: staggering and paralysis of the hind limbs and then the lower limbs until they lay on the floor. Then the picture worsened with total paralysis and cardiorespiratory arrest.
He explained that a team from the Federal University of Mato Grosso do Sul (UFMS), which was on site before the arrival of the IAGRO technicians, collected samples that are being analyzed in the laboratories of the agency and will help confirm the suspicions of the cause of the Death of animals. “Liver and rumen samples were collected from dead animals, moist rations of corn, common silage, hay and water,” he explains.
The CEO of Iagro comments that the suspects that the animals were intoxicated due to the ingestion of moldy wet silage because this product is the one that offered the most favorable conditions for the proliferation of the bacterium that causes botulism. “Another type of silage, corn drought, was offered in addition to cattle to other animals that showed no symptoms of intoxication. In addition, as soon as the feed was suspended with the moist feed, the deaths ended, but we continue to monitor, “he explained.
He also ruled out the possibility that the contamination occurred because of the water the cattle consumed because the reservoirs were recently cleaned and other livestock on the same product did not show symptoms of intoxication.
Chiochetta pointed out in relation to the death of the animals that it is a clinical suspicion of botulism and not an infectious disease. “Botulism is an intoxication that occurs by toxin, because of a bacterium that found ideal conditions to multiply. It is not transferable. The animal ingested food contaminated with the bacterial toxin “.

Boaters around Perdido Pass and other areas of Orange Beach have noticed an unsettling phenomenon in the last few days- hundreds upon hundreds of dead fish at the surface of the water.
It’s known as a fish kill, and it’s an unfortunate thing to witness. While not entirely uncommon, the last fish kill in our area was almost exactly two years ago.
According to scientists at the Dauphin Island Sea Lab, this particular fish kill looks to have been caused by a low oxygen event rather than a red tide- a name given to a large concentration of algae known to kill sea life.
“High nutrient, freshwater runoff contributing to normal phytoplankton blooms, along with relatively low wind and slack tides, will often lead to low oxygen events, especially in the summertime when water temperatures are high,” the Sea Lab representative said.
With so many fish afloat in the water and washing ashore, the city jumped into action to begin cleanup efforts.
“The City of Orange Beach began to experience a fish kill last weekend and immediately responded by activating our standing debris removal contractor Crowder Gulf,” said Ken Grimes Jr., City Administrator for Orange Beach. “Contracted employees working alongside city crews from our Coastal Resources Division and Public Works responsible for shoreline cleanup, the effort collected and disposed of a significant share of dead fish floating and trapped along shorelines specifically in the Cotton Bayou and Perdido Pass area.”
Heavy rains recently without significant winds to churn the water have contributed to the low oxygen levels in the water.
“We always take these environmental issues seriously and work to respond quickly to mitigate the negative impacts for our businesses, residents and guests,” Grimes said. “The last major fish kill was exactly two years ago during the same week of the year. It’s an odd phenomenon but we appreciate everyone’s patience.”
With an outpouring of concern on Facebook and other social media channels, the problem quickly became the talk of the island. Orange Beach officials responded just as fast.
“It’s great to have an elected body that realizes when such an unpredictable event occurs, they are fast to support staff recommendations on covering unbudgeted expenses related to a response like this,” Grimes said. “Led by Mayor Tony Kennon, we always focus on the best and most effective response to serve the greatest good. Our environment here on the Alabama Gulf Coast means everything.”
