Dead fish drift to Vinh Yen Wharf in Van Ninh District. Initial report says deaths may have been caused by red tide.
Mass fish deaths off the coast of Van Ninh District in the central coastal province of Khanh Hoa since Thursday are likely due to red tide, said a local official.
Secretary of Van Ninh District’s Party Committee, Vo Hoang Hai, told the vov.vn that the fish deaths might be a result of a phenomenon known as an algae blooming in which algae grow out of control while producing toxic effects.
About ten tonnes of dead fish had been found, Hai said, adding: “The dead fish mainly lived and fed in the demersal zone – grouper, pomfret, red snapper, and whitings.”
A certain amount of baby lobster, cobia, and Babylonia areolata (a species of sea snail) raised in cages by local residents were also found dead.
Local authorities have taken samples of the fish and water in the area for testing.
“Dead fish have been collected to prevent environmental pollution while local people are urged not to use them until the cause of the deaths is known,” said Hai.
In an extension of 20 kilometers in the marshes of Escuinapa were located about 40 tons of dead fish from lack of oxygen due to the saturation of algae, Carlos Simental Crespo said.
“Most likely it is due to an accumulation of factors, ie, there are many sources of contamination to the very strong marshlands … the purinero, municipal sewage and agrochemicals that fertilize the valley, which had caused a proliferation of algae that consume oxygen all night and consume more than normal, ie, low oxygen killing the fish, “explained the executive director of the Ecological Network in the municipality.
It mnifestó the plague extends from the estuary Agua Grande to El Mezcal, ie, a distance of over 20 kilometers.
Simental Crespo said that this mortality can lead to a strong health problem by different bacteria that can proliferate.
He ruled out the use of heavy minerals such as cyanide, are linked to this phenomenon.
This phenomenon was detected on Wednesday by fishermen in the area.

Mass death of fish cage culture in Vinh Hien (Phu Loc district, Thua Thien Hue Province) is determined by the sweet shock of brackish water.
19/11 days, news from the Environmental Protection Thua Thien Hue province, said the department has issued a notice of the results of water quality analysis Cau Hai Lagoon in areas with brackish water fish cages belonging Vinh Hien (Phu Loc district) died recently. The cause mass death of fish cage last week was initially determined to be shocked by the water (brackish water freshening).
Notify see, at the time of sampling and analysis, most of the parameters for evaluating the quality of surface water are within the permitted limits of national technical standards for the quality of the surface water-MT NTR 08: 2015 / BTNMT (water supply – after applying conventional treatment) and national technical regulations on marine water quality QCVN 10-MT: 2015 / BTNMT (aquaculture areas, aquatic conservation).
HAMPTON BAYS, N.Y. (WPIX) — Thousands of dead fish were found Monday morning in a Southampton canal after they couldn’t get enough oxygen in the shallow body of water.
Fishermen and passersby near the Shinnecock Canal in Long Island noticed what one person called a “sheet of fish” and alerted authorities Monday morning.
State police and officials from the state Department of Environmental Conservation were on scene investigating, according to multiple news outlets.
The deaths of these bunker fish — in what’s known as a fish kill — was likely caused when they were chased by larger predators into the the small Hampton Bays canal, a confined space where there isn’t enough oxygen to go around.
Scientists told PIX11 News they don’t think the fish kill was caused by chemical pollution, but officials will have to clean up the canal before the smell of dead fish spreads.
A similar incident happened in June 2015 on Long Island, when low oxygen levels caused a massive die-off in Riverhead, and again in September inCenterport.

Boating through the Edward and some of its tributaries on Sunday, the Edward Wakool Angling Association president says he’s never seen anything like it in his lifetime.
Mr Fisher labelled it an ‘‘environmental disaster’’ and is calling on ‘‘politicians and bureaucrats’’ to visit the area from Canberra and Sydney to see the devastation for themselves.
‘‘I’ve witnessed the devastation and hopeless situation unfolding in the Edward River, and no doubt countless other parts of the Murray system, due to hypoxic blackwater.
‘‘I put my boat in at Lawson Syphon (near Deniliquin) and travelled upstream into the Tuppal, Gulpa and Edward where I saw dead fish and dead birds, and the smell of the water was septic.

COLUMBUS, Ohio (AP) – Biologists, river advocates and environmental officials are trying to figure out why mussels are dying in a central Ohio river known for its biodiversity, raising concerns about the creek’s long-term health.
Dozens of dying or dead mussels have surfaced along miles of Big Darby Creek since October, Anthony Sasson, freshwater conservation manager for the Nature Conservancy in Ohio, told The Columbus Dispatch
Mussels are highly sensitive to environmental changes, making them “canaries in the coal mine” for ecosystems linked to the creek, said John Tetzloff, president of the Darby Creek Association president.
“This is one of the few last healthy rivers in America. If we lose that we’re losing a key piece of our heritage,” said Tetzloff, adding that the development “could be the end of Darby as we know it.”
Biologists, mollusk experts and state and federal officials met Oct. 20 to discuss the die-off. They’ve been surveying the stream and collecting samples, but say it could be weeks before they determine a cause, the Dispatch reported.
