Furthermore, Nothing … Nevertheless, The emblematic animal of Norway has dramatically rare in the Scandinavian country, victim of climate change and aquaculture.
“When I was a kid in the early 80s. Consequently, the river overflowed norni: agonie du saumon sauvage with fish at a point that we cannot imagine. Consequently, It was filled with sea trout and salmon. Moreover, You could catch 10. Meanwhile, 15 in one evening, ”explains this sports fishing enthusiast, planted in the Stjørdal river (center) swollen by the rains.
Despite his decades of experience, the fifties have been held out for ten days. Moreover, Because salmon is rare. Furthermore, so much so that Norway has placed it in 2021 on its red list of almost threatened species. Therefore,
An ever greater proportion of these fish that migrate between fresh water. For example, salt water do not come back to spawn at their place of birth, upstream of rivers. They disappear at sea for still mysterious reasons but that scientists think linked to climate change.
Only 323. 000 norni: agonie du saumon sauvage wild salmon Raised the Norwegian rivers in 2024, less than a third compared to the 1980s, according to the Scientific Committee for the Management of Salmon, an independent body set up by the authorities.
Enough to worry anyone who indulges. have lived sports fishing, a practice that has entered Norwegian DNA since the 19th century.
With wild salmon fishing
“Salmon fishing is very important for Norway. both for local communities in river valleys and for the economy. And it attracts many tourists. ”underlines Aksel Hembre, vice-president of Norske Lakselver, an association bringing together the operators of the salmon rivers.
But. faced with the collapse of the Montaison (the number of fish that go up the rivers), the authorities suspended it in 33 rivers last year and accompanied it norni: agonie du saumon sauvage this year of restrictions (closure of certain rivers, shortened seasons for others, quotas).
A blow for tourism professionals. the 60 to 80,000 sports fishermen who engage in their passion in rivers where the population of salmonids is considered to be abundant.
If perceptible climate change in rivers (warming of water, precipitation and drought …) and at sea (modification of the ecosystem and food sources …) is difficult to stop, another manager is pointed out: aquaculture.
Aquaculture success
Since the 1970s. Norway has produced breeding salmona lucrative industry which brought back 10 billion euros in 2024 – second export product behind hydrocarbons – and which creates welcome jobs on the coast.
Its fjords are traveled by hundreds of aquaculture farms. Each of their norni: agonie du saumon sauvage six to twelve floating cages can contain up to 200,000 fish.

Not only is breeding salmon. according to some estimates, a thousand times more numerous than wild salmon, but it also helps to lighten its ranks.
The main threats it hovers are linked to sea lice -parasites swarming in farms -escapes that can generate unwanted genetic crossings. and diseases, according to the Salmon Management Committee.
When youth juvenile salmon (the “smolts”) migrate to the sea. pass near the farms, “if they catch a lot of these parasites, they gnaw at their skin, can suck their blood, and eventually kill them,” said the president of the committee, Torbjørn Forsth.
“The crossing between wild salmon. breeding salmon is problematic, because the breeding salmon is selected and adapted to the environment of an aquaculture farm, which is obviously very different from the natural environment,” adds the researcher. “Some of the characteristics of these fish (such as its rapid growth, note) are therefore very harmful for wild salmon”.
To eradicate these problems. many voices rise so that the cages, now open to their environment, give way to closed, hermetic but more expensive systems.
“We demand that there are no emissions, no fish leaks, and no impact of lice on wild salmon. This is essential if we want to save it, ”underlines Aksel Hembre.
If she says she is concerned about wild salmon, the aquaculture industry takes time.
“It does not progress very quickly because it is quite complex. Imagine building a closed system and installing it at sea, compared to an open system. There is a lot to take into account. ”says Øyvind André Haram, spokesperson for Norwegian Seafood Association, which brings together heavy goods vehicles.
“Can something break?” Can some elements be norni: agonie du saumon sauvage affected by marine currents or those of the fjords? It is therefore much more time to be 100% sure than this system is safe, ”he says.
The sector also requires more studies to explain the decline in stocks.

Regulate aquaculture
For its part. the Parliament agreed in June on a text providing for a regulation of farms within two to four years and which should push the sector to switch to closed cages.
“They are moving on a mouse. while wild salmon needs a revolution,” regrets Ann-Britt Bogen, who manages a cottage on the banks of the Gaula river.
