(IMR/PINRO Joint Report Series;2024 - 7, Research report, 2024)On 30th March 2022 all Russian participation in ICES was temporally suspended. Although the announcement of the suspension stressed the role of ICES as a “multilateral science organization”, this suspension applied not ... -
Survey report (Part 2) from the joint Norwegian/Russian Ecosystem Survey in the Barents Sea and the adjacent waters August-October 2023 — Marine environment, Mesozooplankton, Commercial Demersal Fish, Fish Biodiversity, Commercial Shellfish, Benthic Invertebrate Community, Marine Mammals and Seabirds
(IMR/PINRO Joint Report Series;2024 - 9, Research report, 2024)The aim of the joint Norwegian/Russian ecosystem survey in the Barents Sea and adjacent waters, August-October (BESS) is to monitor the status and changes of in the Barents Sea ecosystem. The survey has since 2004 been ... -
Panel-based assessment of ecosystem condition as a platform for adaptive and knowledge driven management
(Peer reviewed; Journal article, 2024)Ecosystems are subjected to increasing exposure to multiple anthropogenic drivers. This has led to the development of national and international accounting systems describing the condition of ecosystems, often based on ... -

Omega-3 Futures in Aquaculture: Exploring the Supply and Demands for Long-Chain Omega-3 Essential Fatty Acids by Aquaculture Species
(Peer reviewed; Journal article, 2024)Long-chain polyunsaturated fatty acids (LC-PUFA), like 22:6n-3 (Docosahexaenoic acid; DHA) and 20:5n-3 (Eicosapentaenoic acid; EPA), are recognized for a range of important physiological roles in many aquaculture species. ... -
Ecosystem risk from human use of ocean space and resources: a case study from the Norwegian coast
(Peer reviewed; Journal article, 2024)Coastal and adjacent shelf waters are generally highly productive ecosystems harboring important ecological processes and exposed to a range of anthropogenic pressures from land-based and marine sectors. Ensuring that the ... -
Effect of environmental drivers on the spatiotemporal distribution of mackerel at age in the Nordic Seas during 2010-20
(Peer reviewed; Journal article, 2024)A joint spatio–temporal distribution model of mackerel (ages 3–10) was developed to investigate the age-based responses of mackerel to three environmental drivers: sea surface temperature (SST), mixed layer depth, and ... -
Impact of aggregate-colonizing copepods on the biological carbon pump in a high-latitude fjord
(Peer reviewed; Journal article, 2024)Zooplankton consumption of sinking aggregates affects the quality and quantity of organic carbon exported to the deep ocean. Increasing laboratory evidence shows that small particle-associated copepods impact the flux ... -
Warming changes the life history composition of marine fish communities at high latitudes
(Peer reviewed; Journal article, 2024)Across marine ecosystems, species are redistributing as a response to increased sea temperatures. In the Arctic, rapid warming causes poleward shifts of boreal species. Which species are redistributing and the drivers of ... -
Are rigid sorting devices necessary to control size selectivity in demersal trawl fisheries?
(Peer reviewed; Journal article, 2024)Diamond mesh codends are the most common size selectivity devices in trawls for releasing bycatch and undersized individuals. However, codend selectivity can vary due to the flexibility of the netting meshes, making ... -
Virus-specific antibody secreting cells reside in the peritoneal cavity and systemic immune sites of Atlantic salmon (Salmo salar) challenged intraperitoneally with salmonid alphavirus
(Peer reviewed; Journal article, 2024)The development and persistence of antibody secreting cells (ASC) after antigenic challenge remain inadequately understood in teleosts. In this study, intraperitoneal (ip) injection of Atlantic salmon (Salmo salar) with ... -
Towards eDNA informed biodiversity studies – Comparing water derived molecular taxa with traditional survey methods
(Peer reviewed; Journal article, 2024)Managing natural resources in a sustainable manner requires understanding the complexity of ecosystems and the species that are associated with the different parts of the ecosystem. Much of this knowledge is derived from ... -
The Eurasian Arctic Ocean along the MOSAiC drift in 2019–2020: An interdisciplinary perspective on physical properties and processes
(Peer reviewed; Journal article, 2024)The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC, 2019–2020), a year-long drift with the Arctic sea ice, has provided the scientific community with an unprecedented, multidisciplinary ... -
Ecological interactions between farmed Atlantic salmon and wild Atlantic cod populations in Norway: A review of risk sources and knowledge gaps
(Peer reviewed; Journal article, 2024)Aquaculture provides an important and expanding source of protein rich and healthy food to the world. However, to minimize environmental harm from aquaculture, interactions with wild fish communities need to be thoroughly ... -
Exploring Growth Patterns of Maurolicus muelleri across Three Northeast Atlantic Regions
(Peer reviewed; Journal article, 2024)Maurolicus muelleri is an important component of mesopelagic ecosystems; nevertheless, we possess only limited knowledge about its biological features. We collected samples of M. muelleri from six scientific surveys between ... -
Diversification of marine aquaculture in Norway under climate change
(Peer reviewed; Journal article, 2024)Recently there has been increased interest in species diversification in aquaculture as a strategy to adapt to climate change. Since species diversification is a long-term strategy, climate change and future farming ... -
Intercorrelations of Chlorinated Paraffins, Dechloranes, and Legacy Persistent Organic Pollutants in 10 Species of Marine Mammals from Norway, in Light of Dietary Niche
(Peer reviewed; Journal article, 2024)Short-, medium-, and long-chain chlorinated paraffins (CPs) (SCCPs, MCCPs, and LCCPs) and dechloranes are chemicals of emerging concern; however, little is known of their bioaccumulative potential compared to legacy ... -
