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
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 dead fish and crabs wash up in a lake in Kucukcekmece, Turkey #Fish Crabs #Küçükçekmece #Turkey
Thousands of fish and crabs that died in the Küçükçekmece Lake that have not been determined yet have hit the shore.
Citizens and fishermen, who say that similar incidents happen every year, noted that recent fish deaths are higher than in recent years.
Some fishermen gather the dying fish and throw them into the sea with their boats.
Istanbul Agriculture and Forestry Manager Ahmet Yavuz Karaca , in a statement to the AA reporter, stated that they sent a team on pollution and fish deaths in the lake and said, “We took samples from dead fish and water and sent them to the laboratory. We will share them when the results are announced. times we can say that deaths are more. ” said.
Emin Şence, who has been fishing for many years, said that the primary cause of mass fish deaths is pollution and lack of oxygen in the lake.

Thousands of dead fish, crabs and shrimps found in Murcia, Spain
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 #fish, #catfish, #crabs found in a canal in #NewOrleans, #USA
State wildlife experts are investigating a large fish kill at Myrtle Grove. Thousands of dead pogies, catfish and crab surfaced at the canal, and the boat launch all day, just days after Hurricane Barry’s storm surge moved out.
First it was Barry and the floods that followed. Now fishermen in this prime area are having to deal with a smelly large fish kill at a popular boat launch.
Pearl Young, who has fished the Myrtle Grove marina for years, said she didn’t like what she saw today, or smelled.
She fished right off the dock and had little luck, while others went farther out to find clean water.
The fish kill comes just days after Hurricane Barry pushed storm surge into this area. Huge sandbags used to shore up the levee are visible from the launch and many say it’s not unusual to see dead fish like this after tropical weather.
Thousands of pungent-smelling dead fish were visible hundreds of yards from the launch, but fishermen went out anyway to try their luck and checked their spots.
The fish kill created a feeding frenzy for seagulls.

Hundreds of crabs wash up dead on Collier, Lee County beaches in Florida, USA

Crabs are the latest casualty of Southwest Florida’s lingering red tide problem as hundreds of them have washed up dead or dying on beaches in Collier and Lee counties since Saturday.
Billy Norris, a Naples resident and owner of Pale Horse Fishing Charters, was at Bonita Beach Monday where he saw masses of dead crabs.
“They were all crawling out because I guess they couldn’t breathe in the water,” Norris said. “Then they were dying on the beach. The sheer amount of them was pretty amazing.”
On Wednesday, Bonita Beach’s water was a rusty, red color and its shore was still littered with crab claws and dead or dying crabs of different sizes and species including blue crabs, Atlantic horseshoe crabs, calico crabs and Cuban mole crabs.
Bonita Beach in Lee County is not the only area where dead crabs are washing ashore. Connie Deane, a Collier County spokeswoman, said dead crabs have had to be cleaned up at all Collier beaches since last Saturday.

Thousands of dead #crabs washing up along coast of #Oregon, #USA

A whole lotta dead Dungeness crabs are washing up as of late, and it has some a little concerned.
Some of it is just the usual crab molting that happens right about now: beaches this time of year can be flooded with the empty shells of crabs that have shed their outer layer as part of their normal growth process.
But many of the crabs are simply dead carcasses, with their meaty bodies still inside the shells. It’s an unusually large amount of them: just about every beach on the Oregon coast is strewn with hundreds of them, sometimes thousands.
The culprit is a simple upwelling. This is when cold water gets churned up suddenly by a certain set of weather conditions and it brings up gobs of things from the bottom. This is definitely responsible for all the crabs washing up.
However, are there more dead crabs than usual? Is something causing them to die off in bigger numbers, or is it just that the ocean bottom got scoured a bit more than usual?
Cannon Beach’s Haystack Rock Awareness Program thinks it is an unusual amount of dead bodies mixed in with the molts, according to their Facebook posts. They believe it’s quite possible there’s a bigger die-off than usual.
There is evidence this is just a normal upwelling event and not a die-off, however. Seaside Aquarium education specialist Tiffany Boothe said she has found lots of other things as well.
“Along with the dead crabs we are also seeing a lot of tube worm casings, mole crab molts, and hatched out snail eggs,” she said.
