Dead salmon found strewn along the beach at Fishery Bay in recent weeks are being tested by Primary Industries and Regions South Australia.
The department received a report of hundreds of dead salmon washed up along the beach last Monday night, April 30.
Fisheries officers inspected the area and collected samples of the fish for testing.
A spokesperson for the department said the test results were expected back early this week.

About 125,000 salmon have died due to a disease outbreak at two fish farms on the Isle of Lewis, BBC Scotland has learned.
Marine Harvest confirmed that the sites in Loch Erisort have been hit by the bacterium Pasturella Skyensis.
The company has apologised to local people concerned about the smell of decay in the area and the sight of lorries carrying away dead fish.
The pathogen is believed to have taken hold at the farms at the end of August.
One theory behind the emergence of the disease is that climate change and rising ocean temperatures could be making Scottish fish farms more vulnerable to bacterial infections.

More sockeye salmon are dying before they spawn this year, and scientist want to know why.
Biologists with West Fork Environmental collect sockeye carcasses as they cover more than 20 miles of salmon habitat in the Cedar River each week.
So far this season, they’ve picked up 1,600 dead fish. They mark the GPS location of each carcass and tag the fish. This year, they’ve found more sockeye dying before they ever spawn.
“That’s been one of the biggest Eureka’s and surprises, but it’s not a good one, because there’s mystery around this disease or suite of diseases, and then problems with what we can do to counteract it,” Michelle Koehler, who works with Seattle Public Utilities on the carcass survey.
The heads of the salmon are dissected for the otolith, which is a piece of the inner ear that tells scientists whether the fish are hatchery or wild sockeye. It also tells age and provides clues about environmental conditions during the sockeye’s lifetime.
Scientists want to know how hatchery sockeye affect wild salmon. The collection also shows whether the hatchery fish are spawning around all parts of the river.
“That’s what these scientists have actually been able to verify,” said Michelle Koehler, who works with Seattle Public Utilities on the carcass survey.
The disease that is killing the salmon is likely caused by a parasite, but it could be more common with warming water temperatures. There is no human health risk associated with the disease, according to West Fork Environmental.

The call came in at the end of a busy day last week: ‘Cermaq is experiencing a mass die-off at two of their farms in Clayoquot Sound’. By early morning the next day we had assembled a volunteer boat driver and photographer, sourced a donated water taxi, and raised the funds to fuel the boat and hire a videographer complete with drone. We set off in anticipation.
The first farm we got to didn’t seem to have any unusual activity, other than the whole Herbert Inlet was a weird murky turquoise. An employee boated over to photograph us, and a polite exchange followed. ‘We’re not sure what this colour is’, he said. ‘We’ve been seeing it for six weeks—could be Chryso’ (shorthand for Chrysochromulina, a species of algae).
The second farm we reached was the Millar Channel farm, just kilometres north of the site evicted by Ahousaht First Nations, after it was occupied by the Yaakswiis Warriors last September. There was a hum of activity: workers tossing dead salmon into totes, which were lifted and dumped into semi-trailers designed to haul away animal remains. The tubes sucking the dead fish (morts) from the pens were getting plugged up with the sheer numbers, and divers were in the pens unplugging them.
We observed the activity, documenting what was going on and taking video and photos. A fish farm boat then followed us to the Dixon Bay farm, which appeared to be dormant. Time to head back to Tofino to get the word out!

A huge amount of dead salmon and sardines are accumulating on the Pacific coast of Chile since early this year due to the effect of climate phenomenon known as El Niño, reports Telesur .
It is estimated that water has expelled Chilean beaches a total of 40,000 tons of Salomes in the region of Los Lagos, representing 12% of the annual production of salmon from Chile. This month also appeared 8,000 tons of sardines in the mouth of the river Queule.
In addition, they have also discovered thousands of dead shellfish and clams stacked on the coast of the Big Island of Chiloe, as well as several cuttlefish dead on the shores of the island of Santa Maria.
Scientists blame these anomalies climate phenomenon El Niño, which causes warming of the surface waters in the Pacific Ocean Ecuador, next to the American continent, raising them to higher temperatures than normal. To this other phenomenon known as red tides, which is the presence of small algae called alexandrium catenella, which generate a venom causes paralysis of the nervous system and kills shellfish and seafood of the area adds. In addition, consumption can be harmful to both other animals and humans.
Meanwhile, fishermen in the region of Los Lagos in Chile, maintain a blockade access to the big island of Chiloe in protest at the lack of support they receive from the government to offset the effects caused by the death of these marine species.

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.
