Immersion and intraperitoneal injection are the two most common methods used for the vaccination of fish. Because both methods require that fish are handled and thereby stressed, oral administration of vaccines as feed supplements is desirable. In addition, in terms of revaccination (boosting) of adult fish held in net pens, oral administration of vaccines is probably the only feasible method to ...

Highly repetitive sequences are the bane of genome sequence assembly, and the short read lengths produced by current next generation sequencing technologies further exacerbates this obstacle. An adopted practice is to exclude repetitive sequences in genome data assembly, as the majority of repeats lack protein-coding genes. However, this could result in the exclusion of important genotypes in newly ...

Protists dominate eukaryotic diversity and play key functional roles in all ecosystems, particularly by catalyzing carbon and nutrient cycling. To date, however, a comparative analysis of their taxonomic and functional diversity that compares the major ecosystems on Earth (soil, freshwater and marine systems) is missing. Here, we present a comparison of protist diversity based on standardized high ...

Proximity between actors within an organisation can be relevant for interactive learning and innovation because it promotes collaboration and knowledge exchange. However, proximity has mainly been studied as a characteristic of the relationships between actors belonging to different organisations. In this paper, a case study of a faculty at a university is used to investigate proximity within this ...

Marine copepods of the genus Pseudocalanus (Calanoida) are common in Svalbard waters as well as throughout the northern hemisphere. They contribute considerably to plankton biomass in addition to Calanus spp. and play an important role in the marine food web as a link between planktivores, such as fish larvae, and microalgae. Pseudocalanus consists of several sibling species, and two of them, ...

Ved hjelp av kvalitativ metode har jeg studert hva som er forløperne til utviklingen av psykologisk trygghet for sykepleierne i akuttpsykiatrien. Slik kan jeg bidra med kunnskap om hva som sykepleierne selv oppgir er viktige faktorer for psykologisk trygghet. Dette kan bidra til et godt arbeidsmiljø og dermed økt stabilisering av sykepleierne som arbeidskraft og gir økt pasientsikkerhet i behandlingen. ...

Knowledge of people's understanding of environmental problems is vital for the effective implementation of the ecosystem approach to marine management. This is especially relevant when conservation goals are aimed at ecosystems in the deep-sea that are remote to the consciousness of most people. This study explores public perceptions of the deep-sea environment among the Scottish and Norwegian public. ...

It is predicted that by the year 2050, the world population will reach 9.8 billion (UN, 2017). The need for fish as a good source of nutrition is also increasing. Total global aquaculture production is now exceeding the global capture fisheries production by over 18.32 million tons (FAO,2019). This increasing demand for aquatic animals as human food, limited marine captured fisheries, and the ...

While European policies have progressed towards an Ecosystem Approach to Fisheries Management (EAFM), limited attention has been paid to the implications for its advisory system. This paper analyses the advisory landscape in the European Union (EU) by addressing two questions: to what extent can the needed advice be provided? how prepared is the management system to integrate ecosystem advice? We ...
