The redfishes (genus Sebastes) are long-lived, commercial species in the North Atlantic. Excessive harvest through decades has led to a decline in the mature population of golden redfish (Sebastes norvegicus) in Norwegian waters, which is currently considered severely depleted. Accumulating genetic evidence suggests a more complex structure within this genus in the North Atlantic, which has ...

This paper explores hypotheses based on Hofstede’s cultural framework showing that decision-makers’ culture impacts their implicit choice. How people make decisions is tested through the behavioral dimension preference for intuition/preference for deliberation based on data from 1,233 employees in China, Taiwan, the Philippines, and the USA. This study reveals significant variation in individuals’ ...

Mitonuclear discordance between species is readily documented in marine fishes. Such discordance may either be the result of past natural phenomena or the result of recent introgression from previously seperated species after shifts in their spatial distributions. Using ancient DNA spanning five millennia, we here investigate the long-term presence of Pacific bluefin tuna (Thunnus orientalis) and ...

A marine-derived Pleosporales fungus, Uzbekistanica storfjordensis, was isolated from driftwood and described as a new species. The fungus was cultivated in liquid media and a molecular networking-driven approach was used to identify potential new secondary metabolites. The targeted compounds were isolated using preparative HPLC-MS, and through extensive spectroscopic analysis, eight new ophiobolin-type ...

Bycatch of threatened flatfish species is a major concern in mixed-species bottom-set gillnet fisheries in the Yellow Sea, China. Therefore, we tested floated gillnets against standard bottom-set gillnets to reduce bycatch by exploiting difference in species-specific fish behavior. Our results demonstrated that the floated gillnet design can greatly improve species and size selectivity. Floated ...

CO2-en fra Melkøya kan brukes som råvare i produksjon av fôr til både mennesker og dyr. Teknologien er allerede utprøvd ut ved ferrosilisiumproduksjonen i Finnfjordbotn.

The use of recirculating aquaculture systems (RAS) for Atlantic salmon (Salmo salar) production has become increasingly common. RAS water disinfection plays a crucial role on its biosecurity. Peracetic acid (PAA) is a promising disinfectant due to its powerful oxidative properties, broad antimicrobial spectrum, and rapid degradation into no harmful compounds. This study focused on assessing the ...

This study investigates the regional demand for shrimp in Norway by employing the linear approximated Almost Ideal Demand System (LA/AIDS) framework. Shrimp consumption has grown significantly globally, with Norway being no exception. The LA/AIDS model allows us to examine the demand of shrimp across different regions in Norway. We utilize comprehensive data on regional shrimp consumption, prices, ...

β-defensin of flounder plays an important role in immunomodulation by recruiting immune cells and has a potential vaccine adjuvant effect in addition to its bactericidal activity. In this study, adjuvant effects of β-defensin on DNA vaccine OmpC against edwardsiellosis in flounder (Paralichthys olivaceus) were investigated. The bicistronic eukaryotic expression plasmid pBudCE4.1 plasmid vector with ...

Denne rapporten utreder konseptet FiskInfoPlattformen: en digital plattform for fangst og bærekraftsrapportering basert på operasjonell datafangst under fiske. Arbeidet har tatt utgangspunkt i grunnstammen i veikartet for databaserte fiskeritjenester som ble etablert i FHF prosjekt 901803 og er første steg i å utvide dette med nødvendig dataflyt for å støtte bærekraftsrapportering. FNs bærekraftsmål ...
