Putting one percent grasshopper meal in the feed doesn’t make it sustainable
In an interview with Intrafish, the CEO of the salmon farmer Cermaq, Geir Molvik, calls for nuances in the debate on alternatives to fishmeal and fish oil (FM & FO), a debate which Geir Molvik feels is based on misinformation and greenwashing.
“Putting one percent grasshopper meal in the feed does not automatically mean that it becomes more sustainable[…] We need new feed ingredients. Not because the ones we use today are not sustainable, but because we need to produce more seafood to reach the United Nation’s sustainable development goals.” Geir Molvik, the CEO of salmon farmer Cermaq, told Intrafish.
FM & FO are scarce resources, and when demand exceeds supply, alternatives might be fruitful. However, to reduce the levels of FM&FO can affect the farmed fish negatively, because FM&FO contains several essential nutrients.
A new study produced by Nofima, among others, has investigated how the change of feed composition in salmon diets have influenced the salmons’ wellbeing. In the year 2000, approximately 30 per cent of the fat in salmon feed came from the ocean, while in 2016, only 10 per cent was marine-based. This decrease of marine-based ingredients has resulted in a significant reduction in, among others, the levels of long-chained omega-3 fatty acids.
The study, published in the international journal of molecular science, indicated that the levels of specific omega-3 fatty acids affected the salmon’s ability to recover from moments where the fish stop eating, such as during spawning or an outbreak of certain diseases.
A new focus on the arctic region
ICES describes the Arctic as one of Earth’s most important regions and finds that the polar ecosystems are changing. The local fisheries are affected by increasing temperatures and melting ice, and ICES is now investigating which ecological changes are likely to take place in the region during the coming decades. Such information will help ICES in its ecosystem approach to fisheries management.
Over the last decade, ICES has prioritized research on the Arctic in order to better understand the ecosystem changes and their effects on natural and human dimensions in that ecosystem.

Released: The EU Blue Economy Report 2020
In June, the European Commission published “The EU Blue Economy Report 2020” which gives an overview of how the economic sectors in EU have performed in relation to oceans and the coastal environment. These sectors provide 5 million jobs and had an annual turnover of €750 billion in 2018, and the blue economy presents a great potential for the green recovery after the coronavirus pandemic. In addition to the provision of food from the sea, the sector also contributes with jobs in coastal communities as well as marine renewable energy. The EU is currently the world leader in ocean energy technology, and it is on its way to produce up to 35% of its electricity from offshore sources by 2050.
The blue economy is an important player in the fight against global warming, and the EU supports it through several innovative investments. With the impacts of the current coronavirus crisis, the EU has taken several measures to protect the EU economy including different sectors in the blue economy.

New study: fish oil improves children’s cognitive functions
A new study has found that an increased consumption of oily fish can have a positive effect on the cognitive functions of children. The attention and processing speed increased for the children who ate oily fish, and in addition the parents experienced a decrease in socioemotional problems. They found that the children who consumed oily fish worried less compared to before. Previous studies have likewise found that an increased intake of omega-3 fatty acids have a positive effect on the brain, and this new research thereby emphasizes that point.
