After a 90% drop in lobster stocks over the past century, new research from the Institute of Marine Research (Havforskningsinstituttet) in Bergen shows that protection zones along Norway’s coast are finally working.
More than 40 municipalities have now established over 70 lobster reserves stretching from the Swedish border to Narvik. These areas ban traps and nets — and it’s paying off. Lobsters are growing larger, and populations are increasing.
Success spreads beyond lobster
Studies indicate that egg and larval production in lobster reserves is seven to nine times higher than in open fishing areas. This “spillover” could also benefit other coastal species such as cod and wrasse.
HI scientists are now examining whether connecting smaller reserves into larger protected networks could strengthen overall marine biodiversity.
Towards a 2030 ocean goal
Norway has pledged to protect 30% of its coastal and marine areas by 2030, in line with global conservation targets. The institute argues that linking marine reserves into a coherent system could protect multiple habitats and ensure the resilience of aquatic life.
“Nature has an incredible ability to heal itself — if we only give it the chance,” said Havforskningsdirektør Nils Gunnar Kvamstø.
