A review of figures showing the amount of aquaculture in the areas that are, or have been, affected by the harmful algal bloom suggests that it was probably not caused by aquaculture. On the other hand, it cannot be ruled out that emissions of inorganic nutrients from fish farms may prolong the bloom.

The bloom of the alga Chrysochromulina leadbeateri in northern Norway has now lasted a week. It’s impossible to say how long the alga will continue to create problems for farmed fish, but there are some indications that it is becoming less harmful.

Wild fish can escape the deadly algal blooms, but farmed fish is held in cages. That is why the algae currently blooming in Northern Norway are lethal mainly to farmed salmon in the area.

On 24th of May 2019 in the Palais du Luxembourg in Paris, François Houllier, Managing Director of the French Research Institute for the Exploitation of the Sea (Ifremer) and Sissel Rogne, Managing Director of Institute of Marine Research (IMR) sign the renewal of a "Memorandum of understanding" which will govern and facilitate the scientific cooperation between the two institutes.

24 of 100 tagged lobsters survived the fishing season. It was not random which ones were caught, a new study shows.

Harmful blooms of Chrysochromulina leadbeateri have led to the death of salmon in the counties of Nordland and Troms. This species of alga is common along the Norwegian coast.

The Institute of Marine Research advises feeding the beluga whale in Hammerfest if it does not take food on its own.

The fishing vessel “Geir II” has caught spawning cod at Jan Mayen.

“This is new knowledge for us,” says Marine Researcher Bjarte Bogstad.

At the Norwegian coast, a white whale with a harness has attracted international media coverage. The animal appeared to have been trained, marine scientist Martin Biuw explains in this article.
