Thousands of dead fish, crabs, eels and other marine life wash up, ‘never seen before’, on the shores of South Florida’s Biscayne Bay, USA #Fish #Crabs #eels #Octopus#Shrimp #Florida #BiscayneBay #USA

Fish Kill Alert

Thousands of dead fish and other sea life washed up this week on the shores of South Florida’s Biscayne Bay.

The fish kill was first reported on Monday. Members of Miami Waterkeeper, an advocacy group, saw about a dozen dead fish when they went out to conduct weekly water sampling. Then reports of dead fish, shrimp, crab, eels, octopus and other animals came in from North Miami to Virginia Key.

“I’ve never seen anything like this,” local resident Kathryn Mikesell told New Times. She has swam in the bay at least three mornings a week for five years.

Researchers and government agencies are still investigating the cause, but indicators point to very warm water temperatures and low levels of dissolved oxygen in the water, according to a news release from Miami Waterkeeper.

“It’s an emergency. The bay is not in a good place right now,” Piero Gardinali, an associate professor at Florida International University who is helping investigate the fish kill, told New Times. “It’s a warning sign.”

In addition to the dead fish, a large group of rays, believed to be struggling to breathe, huddled along the shoreline near the Pelican Harbor Seabird Station, a bird rescue and rehabilitation facility on Biscayne Bay. Personnel from a nearby science aquarium used soaker hoses and air pumps to aerate the corner of the bay where the rays had taken refuge to save them.

Fish and other underwater marine life rely on dissolved oxygen in the water to survive. Warm waters bring those levels down. The Waterkeeper noted very high water temperatures of about 90 degrees in the area where the fish kill was first discovered.

Algae blooms can also cause low oxygen levels, but the Waterkeeper said in an update Thursday that there was no evidence of a toxic bloom. They think an ongoing die-off of sea grass, which produces oxygen, could be a main factor that led to the fish kill.

More than 20 square miles of seagrass has disappeared from the bay in recent years, according to the Waterkeeper. A study last year from NOAA warned that the bay’s ecosystem was on the verge of a “regime shift”. The study found increasing levels of nutrients in the water, which causes numerous impacts that are detrimental to marine habitats.

“We are passing a tipping point for the bay not being able to support any life – literally overnight, the bay became a dead zone,” Miami Waterkeeper said of this week’s fish kill.

“This event is not a ‘normal occurrence,’ but rather a sign that something is seriously out of balance in our bay.”

Thousands of shrimp were found dead last Friday on the shore of La Colonia beach in Águilas. The image surprised neighbors and visitors who were enjoying a day at the beach, when they ran into a trail of about six meters full of these marine decapods.

The Councilor for the Environment, Ginés Desiderio Navarro, explained to LA VERDAD that “what happened in La Colonia is usually common after storms. It is a natural phenomenon. Marine currents occur in this breeding season, and they often take these beings out of the water, who suffocate to death on the shore ». He added that “many fishermen also commented on what had happened, but it is normal.”

Thousands of dead fish, crabs and shrimps found in Murcia, Spain

Fish Kill Alert

THE Mar Menor lagoon in Murcia is in a ‘critical condition’ following the devastating Gota Fria floods, the regional government has warned.

Thousands of fish and crustaceans have died after suffocating due to the change in the water’s properties following last month’s flooding.

According to the regional environment minister, Antonio Luengo, scientists and experts are desperately trying to find ways to inject oxygen into the coastal lagoon, which is the largest of its kind in Europe.

It comes after 60 hectometres of fresh water carrying sediments poured into the Mar Menor, leaving the lower layers without oxygen.

This so-called ‘dead water’ now spreads over 210 hectares.

Jose Garcia Varias from the World Wildlife Foundation tweeted: “Thousands of fishes, crabs, shrimps dead in Mar Menor (Murcia), the biggest coastal lagoon in Europe.

“The situation right now is critical, fishers association of SSF has decided to close the fisheries, thousands of European eels are dead in the coast line (an endangered species which finds refuge in the Mar Menor).”

Thousands of dead #shrimp washing up on a beach near #Naples, #Italy

The Italian coast guard is warning people not to help themselves to shrimp that have been washing up by the thousands on an island near Naples.

In the past few days a tide of dead crustaceans has turned the bay of San Montano on Ischia pink, prompting an investigation by biologists.

“At present the incident seems to be limited to San Montano beach, but the Coast Guard is checking to ascertain whether the same phenomenon has occurred in other parts of the island,” said the commander of Ischia’s coast guard, Andrea Meloni.

He strongly advised against eating the washed-up shrimp, given that it’s not yet known what caused their death.

Scientists from a biological research institute in Naples have taken samples for analysis, which they hope will shed light on the mysterious beaching.

According to Repubblica, there may be a perfectly natural explanation: the shrimp may simply have been caught in strong underwater currents that threw the entire shoal off course, a phenomenon that has been known to happen in other parts of southern Italy.

But authorities have not excluded the possibility that more harmful factors are at work, such as pollution or a sudden ‘bloom’ of toxic organisms, which is becoming increasingly common in warming seas.

Thousands of fish and shrimp die off in a river in Guerrero, Mexico

State and federal authorities are investigating a die-off of thousands of fish and shrimp reported by people living near the Omitlán River in the Guerrero municipality of Juan R. Escudero.
 
Specialists have taken water samples and tissue samples from the fish to determine the cause of the die-off, which residents say has been occurring at this time of year for about seven years.
 
Escudero Mayor Leonel Leyva Muñoz advised residents to avoid consuming fish and shrimp from that part of the river until the causes of their death can be determined
 
However, some residents, normally dedicated to fishing, had already retrieved several fish that were still alive and sold them in the municipal market.
 
The newspaper Milenio reported that some people suspect that the die-off of fish and other wildlife was caused by pollutants spilled at the hydroelectric power generation station located upriver in Carolina, a town in the municipality of Quechultenango.

Seafood died most on May 8, a series of fish floating on the water and lying on the sand.
 
Not only fish but bottom-dwelling species such as prawns, crabs, crabs, and especially deep-sea species like clams and oysters also die in mass.
 
Mr. Vinh Kim, Chairman of Thuan Yen Clam Cattle Cooperative (Ha Tien Town), said: “The clam of the cooperative is close to the harvest date, the white dead, damage billions. Fish and shrimp also die in bulk. “
 
Mr. Phu Cot Lien (resident of Thuan Yen commune, Ha Tien town) chokedly said that he invested more than 1.5 billion for this clot but now lost.
 
Maybe, yesterday I harvested this clam. Expected to catch more than 250 tons, with the price of 21,000 thousand VND / kg, then collected more than 5 billion. But now clams are dead, “Lien said.
 
Truong Anh Vu, a resident of Duong Hoa Commune, Kien Luong District, said: “I drop 15 tons of clams like the last few billion. On harvest day, this is considered as empty hands. “
 
Mr. Van Khen (resident of Duong Hoa commune, Kien Luong district) said: “Previously I dropped nets at the beach near the house stick a lot of fish, but since the fish died so far can not baby brain”.
 
After receiving the information people reflected, Kien Giang province’s functional sector has come down to the field of field inspection and water samples sent to test to find out the cause of dead sea mass.
 
MARD also sent the team to the field and took some samples to take the test to find the cause.
 
A source from the Department of Natural Resources and Environment of Kien Giang province said that the agency had received the results of preliminary analysis of water samples analyzed CENTEMA Center for Applied Technology and Environmental Management related to the sea Mass production mentioned above.
 
Previously, three samples were transferred to this center for analysis to find the active ingredient that can kill fish mass.
 
As a result, there are 17 basic indicators in seawater and 2 indicators of pesticides are in the standard. Particularly surfactant indicators (indicators not in standard 10-MT: 2015 / BTNMT) are higher than normal.
 
In addition to the above three water samples, Kien Giang DONRE collected 7 samples of water for analysis at the laboratory of the Monitoring Center under the Department.
 
Results of the analysis of 7 indicators are included in the standard for QCVN 10-MT: 2015 / BTNMT on coastal water, NH4 + and Coliform only at the point between Tam Ban canal near the sluice gate of Trung Son shrimp pond Is exceeded by environmental standards (3.6 times and 11 times).
 
Currently, the Department of Natural Resources and Environment is awaiting the results of the analysis of phytoplankton criteria and the results of running gas chromatography to determine the origin of the surfactant. At the same time, the Department is also investigating for sources of surface active substances.
 
It is known that to date, the total number of dead fish is 14,000 including 3 types of grouper, squeeze and squirrel. The total area of ​​clam farming is more than 558ha. The damage range extends over 30km from To Chau bridge in Ha Tien town to Binh An commune, Kien Luong district.

Iran’s shrimp production has cut by 50 percent due to white spot syndrome.
 
Arsalan Qasemi, managing director of Iranian Sea Creatures Production and Export Union, said white spot syndrome is widespread in shrimp farms in southwestern Bushehr province, Mehr news agency reported on October 24.
 
We forecast that the disease has destructed 60 percent of shrimp production in the province, he said, predicting that the farmed shrimp output will not exceed 10,000 tons if the current Iranian fiscal year, which began on March 21.
 
Khuzestan and Chabahar – in southwestern and southeastern parts of the country – have also been affected by the disease, but not as harsh as Bushehr, he noted.
 
“Last year, farmed shrimp output amounted to 15,000 tons. Meanwhile, farmed and hunted shrimp output totaled around 23,000 tons. The figure is predicted to be around 17,000 tons.”
 
White spot syndrome is a viral infection of shrimp. The disease is highly lethal and contagious, killing shrimps quickly.
 
Iran exported $10.9 million worth of shrimp in the first half of the current Iranian fiscal year, which began on March 21, a 123 percent rise year on year.
 
Hassan Salehi, the head of Iran’s Fisheries Organization, said on October 11 that 2500 tons of shrimp were exported to 16 countries in the 6-month period, a 108 percent rise compared to the same period in the previous year.
