Miljøeffektene av fornybar energi

NINA har ledet et samarbeidsprosjekt som har vurdert miljøeffektene av fornybar energi. Nå har vi publisert en nettside med interaktive kart som sammenligner vannkraft, vindkraft på land og solenergi. Bransjeprognoser med mer energiutbygging vil kreve miljømessige avveininger. tinyurl.com/4wabb9hd

Pathogen and Gene Expression Profiles of Atlantic Salmon From an Endangered Population The role of pathogens in impacting the behaviour and fate of salmonids has been studied extensively for some selected pathogens such as sea lice. However, the whole pathobiome of the fish are seldom ...

I don't know of any size comparison, but have heard also from others who know pink salmon from the Pacific that they look like they have a higher condition factor here. They certainly look well fed also this year!

Adult male pink salmon

This year, traps will be installed in 63 Norwegian rivers to remove pink salmon before they are able to spawn. New publication assessing these extraordinary measures, based on experiences two years ago: reabic.net/journals/mbi/2025/2/MBI_2025_Thorstad_etal.pdf @ninanatureresearch.bsky.social

Complementing Beach Seining With Dive Surveys Improves Fine‐Scale Resolution of 0‐Group Gadoid Distributions in Nearshore Habitats Located within the Westfjords of Iceland, the fine-scale depth distribution of juvenile 0-group gadoids was surveyed in nearshore nursery habitats using beach seine and dive survey methods. The beach....

🎣 New paper! Combining dive surveys and beach seining reveals contrasting nursery use: 0-group saithe dominate shallow algal zones early in summer, while cod settle later and use broader depths.

Adult Atlantic salmon in a river

Do poor growth conditions at sea result in salmon returning to rivers to spawn at a younger or older age? New study shows that that rapid growth can lead to later maturation but maturation age can be influenced by shifts in growth during the marine migration link.springer.com/article/10.1... 🐟

Submersed Aquatic Vegetation Enhances Density and Diversity of Epifaunal Invertebrates Compared to Filamentous Mats in the Central Baltic Sea This study evaluates the relative importance of Submersed Aquatic Vegetation (SAV) and filamentous mats in shaping epifaunal invertebrate communities in the central Baltic Sea. Our results showed tha....

Submersed aquatic vegetation (SAV) enhances epifaunal diversity & abundance, esp. grazers. 🌱🐌🐚🌊Filamentous algal mats mainly increase gastropod populations. Protecting SAV & reducing eutrophication are vital for sustaining Baltic Sea invertebrate communities.
