One hundred fifty years have passed since the birth of Johan Hjort (1869-1948). Best remembered for his groundbreaking theory from 1914 on the natural fluctuations of fish stocks, Hjort paved the way for materials and methods that are used to this day, not least in climate studies.
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.
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.
The Institute of Marine Research (IMR) is one of the biggest marine research institutes in Europe, with about 1,000 employees. Our main activities are research, advisory work and monitoring.
In January 2018, the IMR was merged with NIFES – the National Institute of Nutrition and Seafood Research. IMR is a leading supplier of knowledge relating to the sustainable management of the resources in our marine ecosystems and the whole food chain from the sea to the table.
