Massive die off of fish found in a lagoon in Cordoba, Spain

The phenomenon, which worried locals, was produced by the intense heat of the last few weeks, whose temperatures surpassed the 38 degrees Celsius. 
 
Roberto Gatti, Member of Commission directive of the Club hunting and fishing of Laboulaye, in dialogue with chain 3 noted that the main species affected is the silverside. 
 
“The amount of dead fish is very important, can’t say how many there are, but are many deceased Silversides,” he said. 
 
“We will wait until a little smell that produce these fish and assess what is what was left. “Have died silverside of 25 centimeters, some large, 600 grams, but I didn’t see kilo, dead”, explained at the time that it anticipated is not the first time that this phenomenon occurs.
 
“Mortality is very large. La Chanchera Lagoon is the last provincial wildlife reserve that has Cordoba towards the South,”he added. 
 
As for the causes of the episode, Gatti pointed to the lack of oxygen by the intense heat: “the cause is lack of oxygen. We had weeks of 38 ° and 40 °. Water, the day of the slaughter, was 29th. “In addition there is a microscopic alga that is generated under these circumstances, which is very consuming oxygen and producing fish to die of suffocation”. 
 
And lamented: “99% are Silversides, though some catfish and carp and bream. We can not do anything, it’s a natural problem”.

200 cows found dead, ‘due to heatwave’ in La Pampa, Argentina

On Thursday afternoon , when the thermal pierced the 40 degrees , 66 animals belonging to the firm Agronor suffered the consequences of high temperatures. Ceferino Orueta, foreman of the establishment, told MaracóDigital.Net that the steers died infartados. 
 
“In this area there is little shade, so the animals pile up to generate it, at the same time generate more heat between them and that’s when they suffer the heat stroke,” Orueta said. ” I never saw something like that, it makes me want to cry,” he added. 
 
The AgroLink site reported losses in fields near Quemú, where 29 other animals were found dead; At the same time, the firm Cereales Quemú would have died about 30 animals.

Hundreds of dead fish wash up on beaches in Montevideo, Uruguay

Fish Kill Alert
Hundreds of fish were found dead in different beaches of the departments (provinces) of Montevideo and Canelones, both to the South, in fact that the authorities of the national direction of aquatic resources (Dinara) attributed to the heat wave affecting that country, local media reported.
 
The Uruguayan Institute of meteorology (Inumet) issued a yellow alert for the 19 departments (provinces) Uruguayans by a heat wave that will bring “extreme” temperatures, which can reach 33 degrees or more in the North of the country.
 
According to the Inumet, “is expected to the persistence of a warm air mass over the country until at least the first days of March”.
 
In that sense, Dinara, Daniel Gilardoni, director told the local newspaper “El País” that high temperatures is one of the hypotheses that handle, since high temperatures there is less concentration of oxygen in the water.
 
However, he said that the first signs of the necropsy of fish, are still in analysis but so far the results have not yielded signs of disease.
 
“It is an extensive mortality but not unusual. There is a history of greater and more widespread phenomena”, said Gilardoni.
 
Similarly, he explained that bathing in these areas “does not represent any danger to health”.
 
According to the Inumet, to the Centre and North of the country, temperatures range from 20 degrees and will reach overcome the 33.
 
In the South and the East, temperatures ranging between 19 and 31 degrees, although they may also exceed this limit.
 
The recommendations range from extreme care with children under 6 years and over 65 people, as well as avoid staying outdoors and do not perform physical exercises between 11:00 and 18:00 hours.

700+ bats dead ‘due to heat’ in New South Wales, Australia

More than 700 flying foxes have died during a heatwave in the New South Wales Hunter region town of Singleton, with many of their corpses still hanging from trees.
 
The mass death at the Burdekin Park colony began Friday and peaked as temperatures hit 47C over the weekend, Wildlife Aid Inc bat coordinator Jaala Presland told 9news.com.au.
 
Video shows the native animals’ lifeless bodies hanging upside down from trees and littering the ground of the town’s central park.
 
“We had half a dozen [live bats brought in] on Friday evening. Saturday we knew the temperatures were looking high again and we had 80 come in, and the death was sort of starting to tally,” Ms Presland said.
 
“The death toll is currently sitting around 700 that’s just from the park currently and very close surrounding areas.”
 
Wildlife Aid Inc had put a team on alert in response to the extreme heat forecast, and other care groups have since travelled to Singleton to help out.
 
The carers must now treat dozens of affected bats, and collect and dispose of hundreds of bodies over the next couple of weeks.
 
“They come in and we need to rehydrate as quickly as possible, their bodies need to be cooled down relatively slowly so they don’t go into shock and then we transfer them out to different care groups,” Ms Presland said.
 
She said there was generally a “small heat stress drop” most summers of about 50 animals, and some deaths during winter and hail storms.
 
The weekend’s toll was the highest since 2500 flying foxes died at the colony in 2004, Ms Presland said. About 2000 bats were counted at the colony before the weekend, and the population now stands at 600.
 
Most of the dead were grey-headed flying foxes, with some black and little red flying foxes also succumbing to the heat.
 
The deaths of little reds was unusual because “generally they cope with higher temperatures”, Ms Presland said.
 
“To a certain degree it is a natural event, however they’re not in a natural environment due to human disturbance,” she said.
 
“In a normal camp you’d have canopies and they’d be able to get down low.”
 
During heatwaves, the flying foxes are faced with staying in the colony and effectively cooking in their roosts or contending with predators if they try to fly away, she said.
 
Ms Presland said the weekend temperatures were some of Singleton’s hottest on record.
 
The Bureau of Meteorology’s nearby Cessnock Airport weather station recorded 46.2C Saturday afternoon, and 45.1C yesterday afternoon.
 
The flying fox colony was established in the town’s central park in 2000, and some trees have been removed since that time. Its population varies greatly as bats frequently come and go.
 
Grey-headed flying foxes conservation status is listed as vulnerable in New South Wales and across the country. They are the largest Australian bats and are found from Queensland to South Australia.

Hundreds of baby turtles dying due to heat on a beach in Queensland, Australia

The exact number of turtle deaths is not known at this stage, but it could be in the hundreds.

Piles of dead turtle hatchlings are lining Queensland’s famous Mon Repos beach amid a heatwave which has pushed the sand’s temperature to a record 75 degrees Celsius.
 
While the majority of hatchlings break free from their nests at night when the sand is cooler, those escaping in the day face overheating.
 
“They can’t sweat, they can’t pant, so they’ve got no mechanism for cooling,” Department of Environment and Heritage Protection chief scientist Dr Col Limpus said.
 
“If they encounter very hot sand they just simply heat up.
 
“They slow down and that’s the end for them.
 
“You really only have probably an hour or so in those really hot sands and it’s terminal.”
 
The extreme heat is also conducted down to the turtle’s nest, pushing the temperature to about 34C, which is approaching the lethal level for incubation.
 
That is the hottest temperature recorded in a nest in more than a decade.
 
“We’ve got an increased mortality … that we haven’t been seeing in years,” Dr Limpus said.
 
The average hatchling survival rate is 85 per cent but due to the heat it is likely to be a lot lower this year.
 
The exact number of turtle deaths is not known at this stage, but hundreds have been seen dead on the beach.
 
The 1.6-kilometre Mon Repos beach is the most important breeding site for Loggerhead turtles in the South Pacific.
 
The majority of the region’s turtles are hatched on the beach, some 200,000 in a usual season.
