HUNDREDS of dead fish found in a Cairns lake are believed to have died of natural causes.
More than 300 fish, including barramundi, mullet and bream, were found dead on the weekend at Saltwater Lake, in Centenary Lakes, Edge Hill.
The Department of Environment and Cairns Regional Council staff inspected the area on Sunday, with field tests suggesting low dissolved oxygen levels caused by high water temperature and lack of water flow were responsible.
Mowing contractor Andrew Smith, who spotted the fish and notified the council, said he was initially concerned the water had been polluted by chemicals.
“The smell was horrific,’’ he said. “It’s just strange that it’s only in Saltwater Lake and not Freshwater Lake, because they’re side by side.”
A similar large-scale fish kill occurred in Saltwater Creek, which feeds the lake, in December last year.
Nearby residents reported a chemical smell emanating from the estuary, but authorities were not able to find evidence of pollutants.
Cairns and Far North Environment Centre director Josh Coates said the weekend incident appeared to have mainly affected larger fish, which could indicate low levels of dissolved oxygen in the water. “When organic matter washes into waterways, the breakdown of the matter can lead to reduced oxygen levels,’’ he said.
“This can happen with early season rains as built-up vegetative matter gets washed into waterways, but in the same way other pollutants, which could include pesticides or herbicides can also be washed in.”
He called for a detailed investigation, including reporting the results in a timely manner, unlike delays in reporting last year’s incident.
“Events like this serve to emphasise the importance of ensuring that pollution does not reach our precious waterways,’’ he said.
“The public, council, business and others need to be looking closely at how vegetation such as grass clippings are disposed of, pesticide use, industrial pollution and the use of herbicides such as Roundup.”
Council crews cleaned up most of the fish yesterday . A council spokeswoman said water testing confirmed reduced oxygenation of the waterway, which could be a result of higher temperatures combined with lower water levels.
“Similar fish kills have often been observed in local waterways at this time of year, when there is a spike in temperature, and it is considered likely to be a natural occurrence,’’ she said.

The Holy Spirit lives the worst drought in 40 years and the drought leaves marks on the rivers and lakes. In town, district Linhares, state of the North, fishermen found dead fish and can not work in Martins Pond.
Simeon Barbosa is a fisherman 61 years ago. Accustomed to see the full fish pond, is saddened to see the scarred earth. “It makes you want to cry to see such a situation is unbelievable, you hear about but do not think it would be like,” he said.
Homesick, Simeon remember that the pond was joy for the community. “When I was meus12 years old, we all fished here. It was filled with water, a fish. At that time you rode a canoe, “he added.
You can now cross the dry pond. “This pond is the first time it dries. It’s the same sadness I’ve never seen this situation, “said the fisherman Leidimar milk.
Biologist Helber Tesch explained that this time of year, should have a considerable amount of rain. Besides the prolonged drought the strong heat increases the evaporation of water. These two factors cause the phenomenon found in the pond.

The dead and dying pilot whales were discovered by hikers on Tuesday night on Stewart Island, 30km south of the South Island, but it was two days before they were able to raise the alarm with conservation rangers.
Ranger Phred Dobbins was one of two staff flown to the site at Doughboy Bay on Thursday.
“Eight of the whales were still alive when we arrived. However, refloating them was not an option given the length of time they had been stranded in hot, dry conditions.
With the tide well out, we saw little hope of keeping the animals alive until enough rescuers could be flown in to assist,” Dobbins said.
The whale carcasses will be left to decompose naturally on the beach due to the remoteness of the site.
Whale strandings are not uncommon in the area, Dobbins said, with conservation staff dealing with a stranding at least once every couple of years.

According to data supplied by officials of the National Fund of cattle, FNG, until last November 3 the number of dead animals product of intense summer plaguing much of the country amounted to 30 thousand 362, with Huila and Tolima most affected.
Rodolfo Montoya, coordinator of Regional Liaison confirmed to livestock context that although the country has made significant rainfall, these have not been enough nor had the perseverance required by the sector. (Read: El Niño will last until June 2016)
“Although there are departments in which no reported changes, our people in region has shown us that the situation is difficult, in a few cases are receiving aid from the agencies responsible and falling water is not it enough to book ahead of ads that El Niño have been made, “he said.

The bizarre spree of dead dolphins washing ashore on Mumbai beaches seems to continue. The latest was a five-feet-long dolphin carcass on Manori beach found on Wednesday, 4 November afternoon.
According to locals, the decomposed body of the marine mammal was spotted on as the tide receded. The carcass, like the earlier ones, was discoloured with bloated internals and fluids spilling from the rostrum (snout of the dolphin).
Fishermen from the area informed BMC officials immediately, who took away the carcass, which was emanating foul stench.
“Dolphins are seen far, in deeper waters, from the Manori coast. It is the first-time around that, a dead dolphin has surfaced here. There were incidents of similar carcasses washed ashore on Versova and Aksa beach,” local fisherman Ramdas Agaskar told iamin over phone.
He claimed of having spotted a pod of four to six dolphins surfacing in and around waters near Versova a month back.
Meanwhile, local ward office of BMC remained clueless as to where the body of dolphin had been taken. “The carcass must have been taken to the dumping ground in Deonar,” said an officer from P/North ward BMC office.
When iamin checked with the Deonar dumping ground, they said no such carcass had been dumped.
12th dolphin body so far
With the appearance of the dolphin carcass at Manori, the total death toll of the porpoises have gone up to 12. Apart from dolphins – bodies of sea turtles, humpback and blue whales have also beached on coastlines in and around the city.
The appearances of marine creature carcasses continue to baffle marine experts and environmental activists, who said that the state must act and investigate these incidents.
“The autopsy reports of the last dolphins could not prove the cause of death. The state must investigate from all aspects as to get to the bottom of these incidents,” said senior scientist from National Institute of Oceanography, Dr Shankar Gajbiye. He suggested that high level of pollutants in sea water to oil spill in deep sea could be few of the reasons for the unexplained deaths.
Meanwhile, state environment minister Ramdas Kadam remained unavailable to comment on the latest incident or on the steps taken by the government to investigate the issue.

Although spawning salmon are still returning to British Columbia’s rivers – including some, surprisingly, to urban streams – early returns indicate another troubling year, despite some bright spots.
“It really is a mixed bag this year,” said Brian Riddell, president and CEO of the Pacific Salmon Foundation. “How the heck can we sum it up? I’d say it’s the good, the bad and the mysterious.”
There were good sockeye salmon returns to the Great Central Lake system on Vancouver Island and to the Nass River on the North Coast, he said.
But contrasting that were very poor returns on the Fraser River, where only about two million sockeye returned, far short of the more than six million predicted in preseason forecasts. Even more dramatic was the collapse of the pink salmon on the Fraser, with only about five million fish showing up when more than 14 million had been forecast.
The federal Department of Fisheries and Oceans declined to provide a spokesperson to talk about the salmon runs, saying it is too early to have firm numbers.
But Dr. Riddell said it is possible at this point to paint a broad picture, and the indication is that some stocks are in serious trouble.
One mystery, he said, is what happened to all those pink salmon that were supposed to return to the Fraser River.
Dr. Riddell said test fisheries in the Georgia Strait in the summer showed a strong run of pink salmon coming in, but then, in what should have been the middle of the run, the fish just stopped arriving.
“With test fisheries, people will typically use a bell curve [to project the size of the run],” he said. “We had roughly 40 per cent of the run in and it was on track with the curve, and then literally within two days it disappeared. It just crashed. … I have never ever seen, nor can I explain, a test fishery like that. The fish are coming in and you are following the proper pattern as they have for years and years, and then they suddenly just disappear. And we have not accounted for them.”
He said millions of fish that should have been coming in the second half of the run just didn’t materialize.
Dr. Riddell said one thing that has been encouraging this fall is the return of salmon to some small Metro Vancouver streams that have been the focus of habitat restoration work in recent years.
This week, chum salmon were seen in both Still and Guichon creeks, which run through busy urban landscapes, under major highways and past massive parking lots.
Dr. Riddell said when salmon spawn in places like that, it is a reminder that the fish are capable of bouncing back if they get decent habitats. Both of those streams were once badly polluted, but water quality has improved and fishways were put in to allow salmon to get upstream.
“These really are resilient animals,” he said. “Sometimes I say salmon have survived despite us.”
Nick Page, a biologist with the Vancouver Park Board, said there are several streams in Vancouver that have been restored or are slated for work in the near future, including Beaver Creek in Stanley Park and Hastings Creek in Hastings Park.
Greg Taylor, of Fish First Consulting Ltd., said the poor returns in B.C. this year are a reminder that more needs to be done to protect salmon and their habitat.
“If we are not going to go the way of Washington, Oregon and California [where salmon stocks have been decimated], then we need to adopt precautionary management. We need to implement the Cohen Commission recommendations and we need more funding for DFO,” he said. “If we don’t do those things, we are risking our salmon.”
In 2012, then-B.C. Supreme Court justice Bruce Cohen completed a $35-million inquiry into the collapse of sockeye stocks in the Fraser River. His report’s recommendations were never implemented by the federal government.

A large number of dead turtles were discovered in a pond in Kankpuri village, Khera Rathore, Agra district, adjoining the National Chambal Wildlife Sanctuary. The pond has turned toxic, forest department officials said. Water samples from it were sent for lab tests.
Villagers were stricken with panic on seeing the large number of dead turtles floating on the pond at Khera Rathore’s Kankpuri village, 70 km from Agra. The Chambal sanctuary is home to turtles, Gangetic dolphins, gharials and crocodiles.
Villagers informed forest officials after the decomposing bodies of turtles caused an overpowering stench. “We saw a few dead turtles on Sunday, but did not think much of it then. On Tuesday, many turtles were seen floating on the water. The stench was unbearable,” said Munna Lal, a resident of Kankpuri.

A warning for you if you’re headed to the beach in Wasaga thanks to the summer-like temperatures: a fish die-off is underway.
The Ministry of Natural Resources says it doesn’t yet know the reason for the large number of dead birds and fish washing up on shore, but they suspect Type E Botulism.
It’s not uncommon for there to be mass die-offs in the Great Lakes.
You’re being asked not to handle dead or dying fish or birds.
Park staff are aware of the problem and are working to dispose of dead fish and birds that are found within the park.

Finnish Food Safety Authority Evira is believed that ihokuoliosairaus is one of the causes of the Torne River wild salmon deaths, but can often be other reasons.
– The final killer is a water mold, but it strikes to any damage to the skin. It would be good, of course, get to the bottom, which is a predisposing factor, or below, characterized by Senior Researcher Perttu Koski Evira’s Oulu unit.
Also Resources Center researcher Atso Romakkaniemi is along the same lines. Ihokuoliosairautta is Romakkaniemi that occurred in the past decade, the southern Baltic Sea, such as Poland, sea trout stocks.
– Some fishermen have estimated that the increase in the Torne River fish up to 20-30 per cent would have been visible skin lesions, but the mortality do not have information about Romakkaniemi.
The dead salmon floating on the shore
Tornionjokivartiset are in any case concerned about the fate of wild salmon. Tapani Kangas For example, a resident of Pello gentle admits that has not been encountered previously in the river’s wonderful show.
Dead fish is displayed continuously and some of them I have raised atraimella the beach. Dead fish were a year ago, but now this has got out of hand, says Tapani Kangas.
A similar vision is also to come across Reijo living in Pello Naamijoella outskirts. Both men will present the race photographs of the dead fish, the most recent of which have taken a couple of days ago.
– The fish is very sick and half-rotten. Some fish have half a head melted away, all fins are inflamed patches and fish is just everywhere. Doom is a pretty total, lists fabric.
The number of deaths is a mystery
So far, jokivartiset have reported that on the bus there are hundreds, even thousands of dead fish. Resources Centre researcher Atso Romakkaniemi estimates that dead fish could be thousands but tens of thousands of escalating amounts he does not believe.
Evira’s that dead fish is in any case more than a year ago.
– This fall, the River Torne is a new powerful salmon spawning time falling ill and dying, emphasizes Senior Researcher Perttu Koski.
Currently, Evira is under investigation dozen derived from the Torne River salmon. They provide further information on the cause of death next week, but the sample of fish continue to be received.
The cause of death of salmon evidence have been throughout the summer hampered by the fact that Oulu has not been enough to fit the fish. However, the authorities operating gall-come, Pello bunch of people, because the sample fish have been ready to send as early as June.
– It is nice to see that the government itself has woken up. The study of fish reception was initially very kitsasta and even banned at some point, but ykskaks end is open. News threshold is seemingly now passed and hopefully we will have clarity for this job, emphasizes Tapani Kangas.
