The corkwing wrasse has a fascinating behaviour. Now, researchers have mapped the sounds made by this colourful fish. 

New research found little evidence that herring and mackerel were responsible for salmon decline. 

Select the right species of fish, find a suitable location sheltered from tropical storms and, hey presto, you can start farming fish in Cuba.

Seafood can play a key role in meeting the UN Sustainable Development Goal of ending hunger by 2030. ⁠⁠⁠”That makes it really important to emphasise the role of seafood and to include it in food strategies”, says research scientist Marian Kjellevold.

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.
