Etterspørselen etter fisk og skalldyr globalt er stadig økende. Økt kjøpekraft og anbefalinger om å spise mer sjømat har bidratt betydelig til dette. De fleste villfiskbestander er allerede maksimalt utnyttet og økningen i produksjonen har i de siste 30 årene derfor utelukkende kommet fra oppdrett. I dag produseres mer fisk til humant konsum i oppdrett enn hva som høstes av villfisk. En av de største ...

Bacteria employ molecular communication systems termed quorum sensing (QS) to sense cell density and organize collective behavior. Many of these behaviors have implications on modern society and human health. As the antimicrobial toolbox of classic antibiotics shrinks due to extensive spread of resistance in pathogenic bacteria, interfering with bacterial communication by ‘quenching’ the QS signals ...

The International Council for the Exploration of the Sea (ICES) is the primary advisory body in the North-East Atlantic, coordinating about 700 marine institutions throughout Europe, five affiliates, and other international projects. ICES offers guidance on a wide range of topics, from the impact of pollutants on individual animals to the state of fish populations and the consequences of numerous ...

The importance of cold-water blue carbon as biological carbon pumps that sequester carbon into ocean sediments is now being realised. Most polar blue carbon research to date has focussed on deep water, yet the highest productivity is in the shallows. This study measured the functional biodiversity and carbon standing stock accumulated by shallow-water (<25 m) benthic assemblages on both hard and ...

Aquaculture impacts on marine benthic ecosystems are widely recognized and monitored. However, little is known about the community changes occurring in the water masses surrounding aquaculture sites. In the present study, we studied the eukaryotic communities inside and outside salmonid aquaculture cages through time to assess the community changes in the neighbouring waters of the farm. Water ...

«Bevaring av marine områder» er i utgangspunktet et samlebegrep for tiltakene «vern av marine områder» og «andre effektive arealbaserte bevaringstiltak». Norges arbeid med bevaring av marine områder er preget av et internasjonalt rammeverk med havrettskonvensjonen som overordnet rammeverk for marin forvaltning i Norge. Konvensjonen om biologisk mangfold, den internasjonale naturvernunionen (IUCN) ...

Det er ikke tvil om at røde blodceller er livsviktige, siden de forsyner kroppen med oksygen, og laksens blodceller frakter oksygen kanskje enda mer effektivt enn våre blodceller gjør. Men det er ikke det eneste de røde blodcellene i laksen kan. De har en cellekjerne som kan uttrykke en mengde gener - de har sensorer for virus og stresshormoner og mye mer - og får signaler fra ...

The rapid, global spread of COVID-19, and the measures intended to limit or slow its propagation, are having major impacts on diverse sectors of society. Notably, these impacts are occurring in the context of other anthropogenic-driven threats including global climate change. Both anthropogenic stressors and the COVID-19 pandemic represent significant economic challenges to aquaculture systems across ...

As an Arctic gateway, the Norwegian Sea sustains a rich diversity of seasonal and resident species of soniferous animals, vulnerable to the efects of climate change and anthropogenic activities. We show the occurrence of seasonal patterns of acoustic signals in a small canyon of Northern Norway, and investigate cetacean vocal behavior, human-made noise, and climatic contributions to underwater ...

Adjuvants are used to increase the strength, quality, and duration of the immune response of vaccines. Neutrophils are the first immune cells that arrive at the injection site and can release DNA fibers together with granular proteins, so-called neutrophil extracellular traps (NETs), to entrap microbes in a sticky matrix of extracellular chromatin and microbicidal agents. Similar extracellular ...
