Thousands of fish dead due to pollution in the River Seiche, France

The Rennes prosecutor opened an investigation to determine the circumstances of the pollution that caused the death of thousands of fish in the river Seiche, from Essé to Amanlis, in Ille-et-Vilaine.
A judicial inquiry is underway concerning the pollution of the Seiche. This summer, in August, the river was contaminated with lactose residue following an incident on a production line at the Lactalis plant in Retiers, Ille-et-Vilaine. The pollution caused the death of thousands of fish over 8 km, from Essé to Amanlis.
How was the situation handled by the factory?
Following the complaint lodged by the Federation of Ille-et-Vilaine for the fishing and protection of the aquatic environment, an investigation was entrusted to the gendarmerie company of Vitré. “It has a dual purpose: to determine the circumstances of the pollution, and to know how the situation was managed by the factory managers, and how quickly the alert was given to the authorities,” said Nicolas Jacquet, the prosecutor of Rennes.
The gendarmes investigate
The investigation will indicate whether one or more offenses are committed. “The gendarmes of Vitré work in collaboration with the services of the prefecture in charge of classified installations and the protection of the environment,” details the magistrate.
No species survived
Findings were made at plant facilities. Hearings of company officials should follow.
No species survived the release of lactose-contaminated water.

Thousands of dead fish found, ‘causing shock’ in a billabong near Darwin, Australia

Screen shot from a video posted by croc wrangler Matt Wright of thousands of dead fish in a shallow river
THE sight of thousands of dead fish and just as many crocs eating them has stopped Outback Wrangler Matt Wright in his tracks.
While flying his helicopter around the Finniss River on Friday afternoon, Mr Wright caught sight of a sea of barra belly-up in a billabong.
He said it was unusual for a fish kill-off to occur at this time of year — and the first time he’d seen anything like it.
“It was crazy, usually you see it when it’s the run off (end of the wet season) and it’s deoxygenated the water,” he said.
“I think these guys have been cooked. We’ve been getting pretty cold nights and the days are hot and the billabong has silted up and the billabong has overheated.”
He said he’d never seen so many dead barra in one spot at this time of year.
“There were about the same amount of crocs having a feast as there were dead fish. There were thousands of them there,” he said.
While he forgot to check if any of the fish had an elusive $1 Million Dollar Barra tag, he said the amount of dead fish was a massive waste.
“You just think about all the waste — there’s just so many dead fish there it’s unbelievable. It stunk too, it smelled like a rotten fish market,” he said. “You see a lot of stuff flying around but that one was definitely something that I didn’t expect.”
A Primary Industry Department spokeswoman could not confirm the cause of the death, but said there were a number of causes for fish kills including environmental factors that cause low oxygen levels in water, toxicants, pollutants, and aquatic diseases.
“Most of the fish kills in the Top End are natural and the result of low concentrations of dissolved oxygen in the water,” the spokeswoman said.
“Fish kills can occur throughout the year in the Top End but are more common during the build-up and early Wet.”

Thousands of dead fish found in a river in Coimbra, Portugal

The Municipal Council of Coimbra (CMC), through the Municipal Civil Protection Service, today called on EDP for the “urgent” opening of the flood gates of the Alto Ceira dam to deal with the large fish mortality in the Rio Ceira.
The continuous discharging of a possible flow would not only be beneficial in terms of water renewal, but would contribute to eliminating the agents that are causing fish death and saving the lives of specimens that may be at risk, as would which are now in putrefaction, to float in the river.
According to the CMC, this is “a real environmental and public health problem with riverine settlements with possible serious consequences for the abstraction and distribution of water for human consumption”. Given the size of the problem, the Municipality alerted the Portuguese Environment Agency (APA), the GNR / SEPNA, the ICNF and the Health Delegation of Coimbra to this situation.
Among other aspects, the Municipality asked these entities to “carry out analyzes of water quality to guarantee their characteristics and, consequently, the supply and health of citizens, in addition to determining the factors that gave rise to this situation; the collection of specimens (fish) for examinations to determine the causes of death and their toxicity; and the confirmation that there is no environmental criminal problem causing this situation. “
Under the supervision of the APA, CMC is intervening in the problem in the face of the public health risks that it entails. In this sense, members of the Coimbra Firefighters Company of the CMC and the Environment Division of the CMC, with a boat, are since this morning in the Cabouco area – at the nascent entrance of Coimbra county – where there were more dead fish , to collect these specimens.
Only during the morning, CMC members collected 280 kg of dead fish, which were taken to landfill; during the afternoon were removed and put in landfill plus 240 kg, which makes 520 kg. The staff involved were even forced to wear masks because of the nauseating smell.
The CMC says it will continue to carry out this collection during the day in Cabouco, Boiça and Tapada.

Massive amounts of dead fish wash up in the Keelung River, Taiwan

Large numbers of dead fish have washed up on the shores of the Keelung River from Zhongshan Bridge to Dazhi Bridge, probably because of consecutive days of high temperatures, the Taipei City Government said.
The city government said it expected to finish clearing the dead fish from the river today.
The Taipei Environmental Protection Bureau said that the amount of dissolved oxygen in the water near the dead fish was 3.5 milligrams per liter, which is about four to five times lower than normal.
The water temperature was 30.3oC, far higher than the average high temperature of 28.1oC in recent years, the bureau said.
The pH of the river was 7.3 which is normal, the bureau said, adding that despite the mass fish deaths the tilapia population in the river was alive and well.
“We suspect that the cause of mass death in fish is not due to contamination, but high temperatures,” the bureau said.
The bureau said it set up netting and floating blocks near the Bailing and Zhongshan bridges to prevent the dead fish washing downriver and was working with the Water Resources Agency to remove the dead fish.
The bureau said it could not give an accurate estimate on the total number of fish killed.
The bureau said that similar incidents have occurred in Yilan County’s Dongshan River (冬山河), Taoyuan’s Laojie Creek (老街溪), the Bitan area (碧潭) in New Taipei City’s Xindian District (新店) and in Xizhi District (汐止).
Taipei Public Works Department official Yu Pai-sung (游百崧) said that the greatest concentration of dead fish was near a river junction.
The department yesterday sent out three boats to help clear the fish, and at least one returned before noon fully laden, Yu said.
The department sent out an additional two boats yesterday afternoon to expedite the operation, Yu said.

Thousands of dead fish found in a nature reserve in Lampertheim, Germany

Sudden fish death in the well-known nature reserve of the Altrhein of Lampertheim: officials of the water protection police had discovered various fish carcasses on the water surface of the former Rhine loop and informed the water and shipping office as well as the office of the city of Lampertheim.
Thereupon the fire brigade Lampertheim, as well as other surrounding weirs and also forces of the THW came out. Boats went to water, thousands of dead fish were collected. A part of this was transferred to the Heppenheim veterinary center, in order to carry out laboratory tests from there. Results will be expected next week. In order to question the background of the fish death, all the enemies were examined in the Lampertheim Altrhein. Since no abnormalities were found here, poisoning as a reason for the dying of the fish is rather excluded. Most likely, fish death was caused by lack of oxygen in the water. In the area of ​​canoeing, a very low oxygen content was measured. The reason for the lack of oxygen is presumably the warm climate lasting in the last few days, as well as a longer waterfall in the Altrhein. The fire brigade and THW had several pumps run from the shore and a boat to enrich the water with oxygen.

Quarter of a million dead fish on a beach in Cornwall, UK

Shocked tourists found a Cornish holiday beach’s golden sands had turned silver overnight as quarter of a million fish had jumped to their deaths to escape being eaten.
Rather than end up as food for shoals of mackerel a few yards out from the beach, the three-inch-long fish appeared to opt for suicide and beached themselves.
An expert believes the fish – which are probably ‘sprat’ but commonly mistaken for whitebait – initially beach themselves to avoid predators but are caught out by the rising tide. 
The amazing scenes left a 200-yard (183 metres/ 600 feet) stretch of Crinnis beach in Carlyon Bay turned to white and silver by the dead and dying stranded little fish.
Spending their final moments gasping and flapping, many became breakfast for flocks of hungry seagulls who rushed in from miles around to feast.
‘The small fish (often called ‘whitebait’ but the species is usually ‘sprat’ Sprattus sprattus) are prey to a whole host of marine animals including mackerel, seabass and cormorants’, Alix Harvey, Head Aquarist at the Marine Biological Association told MailOnline.
To avoid being eaten, the sprat form shoals, hoping for safety in numbers.
‘However, these shoals can end up being chased into very shallow water where, being stuck between the shore and hunters, the sprat panic and become disorientated’, said Ms Harvey.
‘This can cause hundreds of individuals to become beached, particularly if the tide is going out’, she said.
‘I was snorkelling this weekend in Cornwall and saw a huge shoal of sprat – and was lucky enough to see both seabass and mackerel hunting them’, she said.
St Austell woman Nikki Hotchin took photos of ‘the extraordinary sight’ of some of the fish and asked on social media what they were.
One woman commented ‘Was watching the mackerel eating and chasing them to shore. They beach themselves by accident to avoid being eaten.’
In 2014, hundreds of tiny, dead whitebait were also found washed up at nearby Mullion Harbour on the Lizard in southern Cornwall.
At the time the same phenomenon had been reported all along the south coast, with the fish being driven onshore after being chased by predators.
Bob Felce, who has written a book on the history of the cove, said in 2014 that it was an extremely rare sight.
‘It is a rare occurrence. One fisherman who has lived here for over 60 years says he can only remember this happening on two or three previous occasions,’ he said. 
In December 2016 bad weather could have been to blame for the appearance of thousands of dead mackerel and herring which have washed up on a Cornish beach.
Walkers visiting the shoreline said the east-facing Pentewan beach was covered in fish.
Experts say the event is unusual, especially for the time of year, but believe recent windy weather could be responsible.
James Wright, curator of the National Marine Aquarium in Plymouth, told the BBC that such events usually happen in the summer months.
At this time fish, mackerel in particular, follow their prey into warmer waters and then in turn are hunted by something themselves.
He said: ‘It’s quite unusual for fish to want to leave the water, it’s usually a result of panic, because of a predator, but at this time of year that would be unusual.’

Thousands of dead fish found floating in a river in Batang, Indonesia

Thousands of fish were found dead floating on Sambong river, Batang regency, Central Java, on Friday afternoon. 
Thousands of dead fish located in the Sambong river stream or not far from the company Miki Motto Industries Batang it has not known the cause. 
Humani Limited Company Miki Motto Industries Batang, Jack Burhan in Batang, said Friday that thousands of dead fish are estimated because the river water condition is relatively hot enough. 
“Thousands of dead fish are not due to waste waste from Miki Motto companies, but they died because of relatively hot weather conditions and small industrial waste residues upstream,” he said. 
He said his company routinely monitors the level of waste pollution and every month reports the condition of the wastewater treatment plant (IPAL) to the Batang regency government. 
“We make sure that the rest of the company’s waste is not dumped into the river, because if thousands of fish die in the river, it is not caused by waste from the company but other factors such as hot weather conditions and other small industrial waste waste,” he said. 
Residents Sambong Village, Taufik, said the death of thousands of fish in the river Sambong not only happen now but it also happened the same thing. 
In the dry season of the previous year, he said, many fish died in Sambong river because the water condition is quite hot. 
“Thousands of dead fish are not just because of the waste waste that is dumped into the river but also because of the weather conditions are quite hot,” he said.
