By cutting out a particular gene, scientists can make farmed salmon sterile. This prevents escaped fish from spawning with wild salmon. Now scientists have also worked out how to produce sufficient quantities of sterile salmon for commercial production.
The CRIMAC centre wants the echo sounder itself to be able to distinguish between herring, mackerel, shrimps and gas emissions. Now scientists have completed their first expedition to learn the “dialect” of herring.
Researchers have reviewed almost everything: from surveys, trawling methods and sampling, to calculations and management strategies. They have come up with new methods and tools. In five years, the REDUS project has made the fish stock advice of the Institute of Marine Research (IMR) more reliable.
With warmer seas and less sea ice around Svalbard, fishing boats and expedition cruise ships move northwards and extend their operational season and areal coverage. The implications of the increase in human activity for the vulnerable ecosystem in this region can be severe.
In a new study, researchers have for the first time measured omega-3 levels in pregnant women from all over Norway. They found that pregnant women who took dietary supplements had the highest omega-3 levels in their bodies.
Sardines, anchovies, horse mackerel and axillary seabream are popular along the African coast. A new study shows that these species contain lots of important minerals and vitamins, particularly if the fish are eaten whole.
