Already withdrew 60 percent of salmon killed by harmful algae in the Los Lagos region. The Government seeks that unemployed are integrated to the restaurant industry and tourism.
They are 34 centres of those affected by harmful algae crops, leaving so far 35 thousand tons of mortality, which corresponds to 21 million dead salmon.
The Sernapesca, Eduardo Aguilera, regional director said that more affected centers have not been reported, realizing that already has pulled out 60 percent of the salmon to turn them into fish meal.
From the Government, the Mayor of Los Lagos, Leonardo de la Prida, said seeking a labour of persons remaining unemployed retraining, where one possibility is that they add to the restaurant industry or tourism.
A proposal that will be analyzed on Tuesday, where participate the regional head, the National Confederation of workers of the Salmon and the single Confederation of workers, in order to find a solution to this crisis which threatens to leave thousands of people without their labor supply.

Four companies in the sector have been reported so far, that have died les about 4 millions of fish product of harmful algae.
The salmon industry is involved in a new crisis, mainly by the delicate financial situation faced by several companies in the sector, low prices and some regulatory changes that could mean a fall in production.
This negative Outlook has joined it a new ingredient in recent weeks: the flourishing of harmful algae (FAN), also known as algal bloom, affecting more than 15 centres of culture in the areas of Chiloé Center and North of the Aysén region.
In this scenario, four salmon-producing companies have reported, since last Friday, who have lost around 5 million fish in total, from this phenomenon. By consolidating the figures, the value of dead fish is equivalent to slightly more than $30 million.
The first company to inform the Superintendence of securities and insurance (SVS) was Camanchaca, who on Friday said that “preliminary estimates indicate that the mortality of fish would amount to approximately 1.5 million fish”. He also said that the centers of crops affected, in the tenth Region, had about 3 million fish with a book value of $22.2 million.
Meanwhile, yesterday, Blumar reported that his Center “Caicura” – X – Region was affected and explained that “the quantification of loss today is approximately 110,000 fish”. The firm noted that prior to the event, Culture Center had 1.2 million fish, a book value of US $7.5 million.
However, he warned that “current weather conditions favour the presence of FAN, so we stay tuned to its evolution with activated contingency systems”.
Another company that saw its cultivation centers impacted was AquaChile. “According to preliminary estimates the loss by the fact would reach to date a total of 2.3 million units of Atlantic salmon (…), with an estimated value of US $15 million”.
He added that its production facilities affected do not have insurance against this risk.
Australis Seafoods was not exempt from this negative situation, since its production Puluqui Center, which has 1.1 million of the salmon species Atlantic, suffered the onslaught of harmful algae.
Although he said no to the SVS many fish died because of this situation, said that “is not possible yet to determine damage actually caused by the mentioned phenomenon, which are estimated at approximately in the amount of US $6.5 million”.
Then publish suffered impacts, the companies said will determine in the short term, what will be the financial impact that each one as a result of this situation.

Nearly 400,000 salmon died in two fish farms in the municipalities of Hordaland. Norwegian food safety authority believes the operation has been irresponsible, and has notified his strongest obsessive-compulsive remedy against the company: the next Bolaks years production must be drastically reduced.
In some cages died over half of all the fish after the combination debugging and disease. The salmon was devastated by not processing the fish farming company postponed it for. Norwegian food safety authority believes that it cannot be ruled out that the company is responsible for several fatal choice that led to the big fish mortality, type BT.
AS in the municipalities of Hordaland Bolaks is same company fisheries Director Life company P2H Holmefjords Invest AS owns 9.62 per cent in. General Manager of the company, Bjørg Mette Mr Holmefjord Antonsen, fisheries Director’s cousin.
This is the fish farming company Bolaks its fjord. Three facilities are located one after another-Skrubbo, Håvikvågen and Mjåneset. The cluster is referred to as “the village”.
Norwegian food safety authority are determined that the next generation of fish must be handled in a completely different way than the last: Bolaks has fought against too much lice, and fail, mean the FSA. They believe it is committed more serious infractions.

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.

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.

Thousands of fish have been killed in a stream sparking an investigation by Natural Resources Wales.
Up to 3,000 fish are thought to have been killed on a mile-long stretch of the Nant Mawr between Ruthin and Denbigh .
They include salmon, sea trout, brown trout, eels and bullheads.
The incident is believed to have been caused by a blockage in the river. This has now been removed and river levels are expected to return to normal shortly.

However, the Nant Mawr is an important spawning stream for fish and the incident is likely to have a serious effect on fish populations in the area.
Nant Mawr is a tributary of the Clywedog which feeds the River Clwyd.
Health warning in Wrexham after toxic algae found in lake
NRW officers warn that as the river flows return to normal, the carcasses are likely to be washed downstream.
The fish may have been dead for a few days and people are asked not to touch the carcasses and allow them to be washed away naturally.
Emyr Jones, leading the investigation for Natural Resources Wales, said: “Fish such as trout and salmon are an important part of the ecology of our rivers and our economy.
“We are now investigating the cause of the blockage and will look at taking enforcement action against anyone who may be responsible.”

The mystery of dead salmon in a Marlborough Sounds fish farm is being worked on by a government agency and the farm’s owner NZ King Salmon.
Officials from the Ministry for Primary Industries and industry representatives met yesterday to mull the causes of high fish mortalities at NZ King Salmon’s Waihinau farm in Pelorus Sound during summer months. The trend was first noticed in 2012.
Response manager Chris Rodwell says MPI believes there are a range of factors at play including high water temperatures, water flow, diet and even sea anemone stings.
Two bacteria not previously detected in New Zealand have also been found.
There are no concerns about food safety associated with this situation, Dr Rodwell says.
NZ King Salmon chief financial officer Andrew Clark says the losses occurred during record high water temperatures.
“We believe this is a significant contributor along with diet and sea anemones. Our research focuses on these areas and we are collaborating with the MPI and sharing the information,” he said.
There’s no proven causal link between the two organisms identified by the MPI and fish mortality, he says.
The company is co-operating with MPI to ascertain if a link exists.
MPI is also working with salmon farmers around the country to collect information and sample fish to determine if the bacteria exist outside of Marlborough.
There have been no reported increased mortality events in wild fish or in farmed salmon outside of the Marlborough Sounds.
As a precautionary measure Marlborough farms put biosecurity controls in place to prevent any spread of the bacteria and MPI is enforcing this.

Very serious event, “said the FSA after the loss of 70 tons of salmon. Authority has pointed out the violation after the incident, and ask the fish farming giant sharpen routines.
The incident occurred in the locality Gulestø in Bremerton. In location a total of 190,000 swam salmon. Almost nine percent died in the course of the findings from the treatment.
Hydrogen peroxide is a disinfectant and one of the most common drugs used in the fight against too much lice on salmon. According to seafood Norway used the industry last year over 30,000 tons of hydrogen peroxide to keep the gate numbers down. It is four times more than the year before.
According to our information was the dosage right. The problem was too little oxygen in the water and too little throughput, said first Inspector Nina Manning in the Norwegian food safety authority. She alerts the supervision at the plant shortly.

In late August, there were reports of dead fish on Lake Koocanusa, a scene similar to one that occurred on the lake two years ago.
It’s not entirely understood what is causing the death of thousands of kokanee salmon, but one fisheries biologist has a theory.
Mike Hensler, who works out of the Libby Field Station, said typically, this type of occurrence isn’t uncommon in large lakes, especially when it comes to kokanee salmon.
“They are relatively fragile fish – canary in a coalmine type of thing,” Hensler told The Free Press. “They are susceptible to dramatic changes more so than other fish are, and when we see these kinds of occurrences, it’s usually associated with hot, calm weather followed by a fairly dramatic storm event.”
The event in this recent occurrence was a heavy rainstorm that hit the area on Aug. 21.
Hensler said what he’s seeing is dead and dying fish on top of the surface of the lake with enlarged gas bladders.
Hensler said the kokanee are limnetic fish, which means they’re out in the middle of the lake most of the time, where other fish are not so they won’t be in the zone where the die-offs are occurring.
“When we were able to sample them as they were dying to see what was happening internally, what we’re finding was they had troubles with their GI track – with the digestive system – so they were sick,” he said. “Now, how they got sick, we don’t know because we never really found full stomachs, but they ingested something that’s a gas.”
There is possibly an algae of sorts is at the surface of the water the kokanee are getting into, but Hensler said that’s just a guess.
This time of year, especially in the evening, there are lots of fish at the surface and because it’s had the summer to heat up, surface temperatures can be lethal, Hensler said, adding the last time they checked the lake’s surface temperature, it was between 71 and 72 degrees Fahrenheit.
While that temperature could be lethal, Hensler said fish have the ability to dive back down into cooler water, but when a fish gets sick, it loses its ability to keep its place in the water column and if this happens, as they go back up towards the surface, their gas bladders expand and a sick or disoriented fish can no longer dive or swim down to decrease the pressure.
“It looks like the actual death has to do with warm water at the surface, but the reason they’re at the surface is still one of those – its’ a guess – and our guess is that there’s something there; something that they’ve ingested that’s causing them to get disoriented and sick.”
As far as he knows, Hensler said the water is safe to swim in, and should someone eat a kokanee, he suggests cooking it well but said there’s no indication suggesting that whatever is causing the die-off is harmful to humans.
While there were several thousand kokanee that died earlier this summer, Hensler said considering there are millions in Koocanusa Lake, it’s nothing to be alarmed about.
“Even if 10-20 thousands of them perish, it’s not the end of the world for kokanee in Koocanusa. It’s hard to say if this is a natural phenomenon, but it looks like it is,” he said, adding it tends to be something that happens in big lakes.
