Abstract The spawning population of invasive Pacific pink salmon (Oncorhynchus gorbuscha) has only continued to increase in the river systems on the Varanger peninsula in Norway, causing concerns across institutional boundaries and management communities. So far, the Norwegian research efforts on Pacific pink salmon have been centred on consequential effects in marine- and freshwater ecosystems, ...

Kongekrabbe har blitt fisket kommersielt i Norge siden 2002 og har blitt en viktig art for den norske sjømatindustrien, med stor økonomisk betydning i lokalsamfunn langs Finnmarkskysten. Med en eksport på 2000 tonn, til en verdi av 579 millioner kroner var kongekrabbe verdimessig den nest største arten i skalldyrkategorien i 2018. Mesteparten av kongekrabbe blir eksportert levende mens de resterende ...

<p>Norsk fiskeindustri har tatt i bruk både ny teknologi og nye styringsverktøy for å øke effektiviteten, forbedre utnyttelsen av råstoffet og styrke fortjenesten. Ett av styringsverktøyene som har blitt introdusert i de seinere årene er Lean. Dette er et styringsverktøy som har sitt utspring i Toyota Motor Corporation og japansk kultur. <p>Denne studien ser nærmere på hvordan Lean er satt sammen ...

Fjord and shelf food webs are frequently supplemented by the advection of external biomass, which in high-latitude seas often comes in the form of lipid-rich copepods that can support a wide range of fish species, including Northeast Arctic cod (Gadus morhua). A seasonal match or mismatch at the lower trophic levels (phytoplankton and zooplankton) is central in determining how much energy and biomass ...

Background: The gene editing tool, CRISPR/Cas9, can potentially be applied in aquaculture to combat some of the problems of the farmed salmon industry including infectious diseases. The RNP (ribonucleoprotein)-based CRISPR/Cas9 strategy has recently been shown to be efficient in gene editing in diverse cell lines and organisms. Application of RNP strategy in salmon cell biology is still at its ...

Institutional barriers are critical obstacles to policy implementation. Such barriers hamper the performance of marine policies and may also limit the potential for adapting governance arrangements in order to improve policy performance. Instigating transformation within longstanding governance arrangements is very challenging and is often hampered by institutional barriers such as path dependency, ...

Shrimp feed formulations have moved towards less fish meal and more of the readily available and cheaper plant proteins. To counteract the lower attractiveness and palatability of plant proteins, feeds are supplemented with ingredients known to have chemoattractive properties that will increase feed intake. This study investigated the putative chemoattractive effect of Calanus finmarchicus hydrolysate, ...

Background Migratory birds generally have tightly scheduled annual cycles, in which delays can have carry-over effects on the timing of later events, ultimately impacting reproductive output. Whether temporal carry-over effects are more pronounced among migrations over larger distances, with tighter schedules, is a largely unexplored question. <p><p>Methods We tracked individual Arctic Skuas ...

Management of thorny skate (Amblyraja radiata) in the Northwest Atlantic has posed a conservation dilemma for several decades due to the species' lack of response to strong conservation efforts in the US Gulf of Maine and the Canadian Scotian Shelf, confusion over the relationship between two reproductive size morphs of differing life histories that are sympatric in the Northwest Atlantic, and ...

The current paper contributes to signalling theory by demonstrating the importance of digital quality signals in influencing consumer preferences for sales and segmentation in the context of marketing fresh fish online. We conducted a choice-based conjoint analysis with a latent class segmentation to analyse the significance of digital quality signals compared to traditional attributes online. The ...
