Greetings from Norway

At the same time Norwegian salmon rivers are being invaded by an unwanted species; Pink salmon or humpback salmon, which is a species of anadromous fish in the salmon family. It is the smallest and most abundant of the Pacific salmon.

Must save the wild salmon with an intelligent trap

Rune Rørstad from Ålesund is collaborating with, among others, Huawei on a system that will stop humpback salmon from invading Norwegian salmon rivers.

The Norwegian wild salmon is endangered and under strong pressure from many quarters. One of the new threats is the invasions of the alien species humpback salmon that disrupt wild salmon reproduction:

The humpback salmon, especially the males, get a characteristic hump on the front of the back during the spawning season

This comes on top of the escaped farmed salmon. Humpback salmon spawn every two years, and river owners and salmon fishermen hold their breath before the 2023 season. It is expected to offer a humpback salmon nightmare in several places.

  • In some rivers, 20,000 to 25,000 humpback salmon are expected in the course of a month and a half.
    Rune Rørstad and his partners believe they have a groundbreaking solution, an intelligent “fish trap”.
    And the partners are not just anyone;
  • We were contacted before the salmon season in 2021, by Huawei, Rune Rørstad tells Sunnmørsposten. The Chinese technology giant had started a preliminary project together with the Berlevåg hunting and fishing association. They were to put out cameras in the river and build artificial intelligence around recognizing different fish species.
  • This is part of Huawei’s “tech for nature” initiative, which is a way for them to show social responsibility. It is about using technology to support something that helps to save nature or endangered species, Rørstad explains.
  • The scheme we are talking about here is easy to understand: the river is closed with a fence, and fish and animals that want to swim up are forced through a tunnel. There, a camera registers the species in question. Wild salmon, sea trout and other of the river’s natural inhabitants are allowed to pass; the hatch opens. Farmed and humpback salmon, on the other hand, are rejected, led to the side and caught.

Rørstad is the leader and largest owner of the company Troll Systems AS. Their job is to create the infrastructure itself.
Huawei is responsible for the camera technology, while a third company, Simula consulting, is developing the artificial intelligence.

  • I am not a biologist, but a building and construction engineer. I can still say for sure that 2021 was catastrophic. The only thing we know about next year is that it will be even worse, says Rørstad.
  • Everyone in the hunters’ and fishermen’s associations is still worn out after last year. They worked around the clock to sort out as much of the salmon as possible.
    It will soon be ready, but will always have to be ordered in advance.
  • First, the individual river must be measured and it is decided where things should stand.
    Neither hunters’ and fishermen’s associations nor landowners alone will be able to afford to buy, the Troll Systems leader believes.
    The price tag will probably be around one million kroner per river.
  • For such projects, they are happy to apply for funding from the County Administrator or the Norwegian Environment Agency, but no one has made such major moves as this before, but the Norwegian Environment Agency has set aside funds for a number of such projects.

Furthermore, an effort is also needed to operate the “fishing trap” during the spawning season.

  • It should be in use throughout the season, and should be taken down before there is ice in the river. Then it must be re-installed next season.
    During the season the traps must be attended - all fish that are not allowed to swim further go into a catch cage and the attendees have to manually sort out this fish. Much of the sorted fish can be eaten. Humpback salmon is considered a good food fish, although only before it has spawned.

From Sunday 26 June, the company will in a couple of days drive equipment from Bodø, to Berlevåg, which is located in the far north of Finnmark. There the scheme will be tried out on farmed salmon.

  • Thursday will be the official opening, or let’s say closing, the entrepreneur says.

PS> Maybe useful to stop invasive species, like Atlantic farmed salmon, in US rivers?
Oh forgot, that probably wouldn’t be allowed if Huawei equipment is involved.

Something that probably is more interesting to most:

From another thread:

Unfortunately the gulf state found a different solution; in stead of flaring the associated gas from the oil production they gathered it, piped it to the coast and used it to evaporate seawater, thus making cheap fresh water without being dependent on anybody else.

BTW; less GHG emission, since they didn’t have to ship water over long distances in fuel burning VLCCs.

Actually there were plans at the time of the tanker crisis to ship fresh water from Norway to Southern Europe/North Africa/Middle East, using VLCCs.

The plans to export water from Norway have been revived recently:
No, not the expensive bottle glacier water from Voss, or ice cubes cut from glaciers, sold at ridiculous prices at exclusive bars in NYC, Las Vegas and Dubai etc.

The water would first go through a turbine to make cheap renewable electricity for households and industry:

PS> Some of that energy could be used to produce “Green Hydrogen” as fuel for the VLCCs.

The tankers to be moored, loaded (and refueled?) near the power stations, with a minimum of infrastructure required, as there are deep water close to shore and all along the fjords:

The water sources are from melting snow and glaciers, collected in reservoirs high in the mountains and piped (or in narrow tunnels) to power stations near the fjords and is “discarded”.

It is clean, so no expensive rinsing process needed. (Silt filtering is done before the turbines)
The water is still potable after passing through turbines and being transported in clean coated tanks over long distances.

The hydro station presently supplying an aluminium smelter is fed from a lake formed from melt water like your Norwegian hydro. The hydro station is inside the mountain 600 metres below the lake. The turbine hall is cut out of granite and the tail races exit in a fiord very much the same as your picture but there are no buildings or people there.

Norway has a lot of hydro power stations and usually a lot of rain and snow to fill the reservoirs that drives the turbines, creating cheap electricity for the consumers and for export to the rest of Europe.

This year has not been a normal year, however. The South and East of Norway has been dry, with little snow in the mountains, causing the reservoirs to be at a very low level:

Little precipitation and little snow in the mountains means that the water level in Dokkfløydammen in Nordre Land is very low.

Consequently the price to consumers where up to NOK 2.80 per kwh

At the same time, due to large snowfall in the winter:

And due to the warm weather now, rapid melting cause the the reservoirs to overflow here in the North West of Norway:

The price to consumers in this part of Norway was as low as NOK 0.03/kwh a few days ago.

One of the main complains among EVs owners in Norway is the different charging connection and the many different charging operators that each have their own app for access and payment.

Here is an advert from a car dealer that offer a simple solution (according to them) to ease the problem:

From FB Group “Old pictures from Ålesund” by Arve Tore Flem

PS> Ålesund was known as “Little London” during WWII due to the traffic of people to Shetland, with weapons, communication equipment, operators and saboteres on the return voyages.
Here is one of the fishing boats that was used for this purpose:

She is now preserved and belong to Sunnmøre Museum She is making trips to Shetland most years for the commemoration there:

Lofoten Islands w/o disturbing comments;

Cruise boat passengers transported down from Nesaksla on special stretchers

An adult woman was transported down from Nesaksla (708 m. asl) on Wednesday by the Rauma Red Cross Aid Corps after sustaining a minor injury. The crews used a wheeled stretcher on the rescue mission.The woman must have fallen or tripped on the stairs between Andersmyra and the summit, and either sprained or broke her ankle. Four volunteer members of the Rauma Red Cross Aid Corps were called to get the patient down from the mountain.
It was considered using a helicopter, but the AMK central decided that it was not necessary because the damage was not considered very serious, says auxiliary corps leader Øystein Valde.
We spent an hour and fifty minutes up and down, so it went quite quickly, said Sivert Hole after the patient had been sent on by ambulance to the hospital in Molde for further examination:

Specially designed

The stretcher used in the rescue operation is specially designed for use in demanding and steep terrain. It has a large bicycle wheel underneath, and is equipped with brakes, and the crews in the auxiliary corps have used it in several demanding operations.
We decided to acquire the stretcher after we had to pick up a person at Puttbua in the heart of Brøstdalen several years ago. We then started to carry the patient down, but soon realized that we were going to wear ourselves out. So then we turned around and went back, and made sure that the patient instead had a comfortable night until he was picked up by helicopter the next day,

The same stretcher has also been used in previous campaigns at Nesaksla.
It is quite steep terrain, also some steep hills. But it went just fine, it’s just a matter of taking it easy, one step at a time. Without the stretcher with wheels, it would have been a much more demanding operation, states the auxiliary corps commander.
A big advantage of using the Red Cross for such simpler rescues is that we are far cheaper than a helicopter, says Øystein Valde with a satisfied smile.
