How healthy is the food of the future?
Lantern fish are a group of mesopelagic fish species, and one of the most abundant vertebrates in the world. But could we have them for dinner? Photo: Oda Linnea Brekke Iden / Institute of Marine Research

Blue mussels aren t quite a novel resource, but researchers are now looking into the potential for using them more than is done today.

Luxuriant Arctic forests
In cold marine waters, rocky reefs are often dominated by habitat-forming seaweeds such as kelp. These seaweeds form impressive underwater forests that are not only a phenomenal source of primary productivity and food, but also create three- dimensional structure that provides valuable habitat for many animals and other seaweeds, including harvested species. The recipe for kelp forests in many regions of the world is deceptively simple: a rocky seafloor, enough light to support growth, cool nutrient-rich waters, and low grazing pressure to ensure survival. Add protection from ice scour to this mix and you have the formula for predicting the potential distribution of kelp in Arctic regions.
Marine Robotics Pioneer Bellingham to Lead Hopkins Institute for Assured Autonomy
Jim Bellingham
Credit: Jim Bellingham Jim Bellingham, a pioneer in the worldwide autonomous marine robotics field who has led research expeditions from the Arctic to the Antarctic, has been appointed executive director of the Johns Hopkins Institute for Assured Autonomy (IAA) in Baltimore. The institute is run jointly by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and the Johns Hopkins Whiting School of Engineering (WSE) in Baltimore. For more than 30 years, Bellingham has been a global leader in the development of small, high-performance autonomous underwater vehicles (AUVs), resulting in a class of systems that are now widely used within the military, industry and science communities. He joins Johns Hopkins from the Woods Hole Oceanographic Institution (WHOI) where he was founding director of the Consortium for Marine Robotics since 2014
Charles Høstlund, CEO Norway Royal Salmon
Norway Royal Salmon has announced it is abandoning plans to continue breeding triploid salmon. The news follows a decision by the Ministry of Trade and Industry to order the suspension of future development work on this type of fish until it can be established it is bringing welfare benefits.
The Norwegian Food Safety Authority has decided that no new triploid smolt will be released after the spring of 2022, and that no triploid salmon should be kept at sea past the end of 2023.
Triploid salmon has three sets of chromosomes, unlike ordinary diploid salmon which has two. The extra chromosome, added through hormone treatment, makes the fish sterile, so if they escape and get into rivers they are unable to interbreed with wild fish stocks.
