These futuristic salmon farming concepts could radically reshape the aquaculture sector. Here’s where the projects stand

November 16, 2020 — Nearly two dozen Norwegian companies have received salmon farming licenses to pursue pilots of their innovative aquaculture concepts, but when these futuristic concepts will hit the water at a large scale remains murky in some cases.

A total of 20 companies received 102 development permits between 2016–2020, and while many have not even begun construction of the projects, the Norwegian government says the green light to pursue the farming systems won’t be turned off.

The development permits (see sidebar) were granted in some cases for a period of up to 15 years, giving companies plenty of runway to raise financing and refine the technology — a critical element to the successful implementation of the projects, according to Anne Osland, section manager for the Norwegian Directorate of Fisheries.

“Many of these projects are very complex, and that it may take some time to get into operation,” Osland told IntraFish.

Norway’s deadly algae bloom may be waning, government says

June 3, 2019 — A deadly algae bloom that has killed nearly eight million Atlantic salmon being farmed in northern Norway appears to be dispersing, according to the Norwegian Directorate of Fisheries.

The bloom, first reported in mid-May, has killed 3.8 million farmed salmon in the Nordland area, the equivalent of 6,400 metric tons, and four million salmon in Troms, or 6,820 metric tons, according to Norway’s Fiskeridirektoratet. Affected companies include Ballangen Sjøfarm, Ellingsen Seafood, Mortenlaks, and Nordlaks in Nordland and South Rollerfish, Northern Lights Salmon, Kleiva Fish Farm, Gratanglaks, Nordlaks, and Salaks in Troms.

“It may seem that blooming is on the way down. Generally lower numbers of algae are recorded, the cells are smaller in size and there are observations suggesting that the bloom/species is less harmful,” the directorate wrote in a 2 June update. “As reported in recent days, there have been high concentrations of algae without causing fish to die. It may happen that the algae bloom up again in smaller areas.”

Many salmon-farming companies in northern Norway have transferred their fish to locations less likely to be affected by the algae bloom. Cermaq, Nordlaks, Ellingsen Seafood, and Nordnorsk Stamfisk have moved fish and broodstock out of Nordland, while Lerøy had issued a notice that it was considering moving fish out of Troms, but delayed its decision as local water conditions improved.

Millions of Salmon in Norway Killed by Algae Bloom

May 24, 2019 — About eight million farmed salmon have suffocated in northern Norway over the past week as a result of persistent algae bloom, an industry body estimated on Thursday, a blight that some experts suggest has been aggravated by climate change.

Norway is a dominant producer of farmed salmon, and the economic impact of the bloom is significant.

A statement from the Norwegian Directorate of Fisheries estimated the amount of salmon lost at 11,600 metric tons, worth about 720 million kroner, or more than $82 million. An industry group, the Norwegian Seafood Council, suggested the total could be much higher.

“Preliminary numbers point to eight million dead fish — corresponding to 40,000 metric tons of salmon that won’t reach markets,” Dag Sorli, a spokesman for the council, said in an email on Thursday. He put the value of the losses at 2.2 billion kroner.

Algae bloom in northern Norway resulting in salmon mortalities

May 20, 2019 — The aquaculture sector in northern Norway is being hit hard by an algae bloom, according to a 16 May statement from Norway’s Directorate of Fisheries.

The algae bloom is affecting the waters between Nordland and south of Troms, an area of about 450 kilometers of coastline.

“Dead fish are registered at some sites, some hit harder than others. This is a serious situation and a significant number of fish have died,” the statement said.

The directorate did not supply a list of the companies or farms affected or the amount of mortalities reported. It said it would report a mortality figure “when such an overview is available.”

The operators of aquaculture sites in the area “are in close dialogue” with the directorate and “are continuously implementing necessary measures.”
