More documentation needed for the efficacy of cleaner fish

11.02.2020

Millions of cleaner fish are used in farm cages to eat lice off salmon every year. However, there is limited research into how efficiently they do this job. Now scientists have gone through all published studies in the field – and found large knowledge gaps.

75 percent fewer salmon lice with new type of sea cage

11.11.2019

Physically separating salmon from salmon louse larvae reduces infestation of salmon by 75 percent compared with a normal sea cage. This has now been scientifically demonstrated using a “snorkel” cage at a commercial fish farm.

Organic mineral supplements are better for fish and the environment

28.10.2019

If farmed salmon receive the minerals in their feed in organic forms, they need smaller amounts of them to grow big and strong. As a result, less of these minerals enter the environment.

Sustainable fisheries: Commitments are important, but cannot replace laws and institutions

23.10.2019

The Institute of Marine Research has analyzed 182 Our Ocean commitments from the past five years. Overall, the commitments have mainly generated attention and funding. The direct impact on sustainable fisheries and management is less obvious.
