This paper presents field experiment results of using a new technology to harvest copepods (Calanus sp.) in the ocean by bubble upwelling. Two largo-scale bubble rafts, a 21 m2 and a flexible 75 m2 bubble raft with tow parallel and perpendicular sparger elements, respectively, were field tested in areas with high, upper 25-m water column Calanus densities. Measured bubble-driven upwelling velocities ...

<p>Fisheries Stakeholders are understandably most concerned with immediate problems. Often these problems are related to proposed rule changes. This short term focus is in itself a serious problem for introducing Ecosystems Based Fisheries Management (EBFM), which is typically seen as a long-term approach. However, the short-term response of fishers to rule changes may well have long-term consequences ...

Interferonsystemet er den viktigste mekanismen i det medfødte immunforsvaret mot virus hos vertebrater. Celler som blir infisert av virus, produserer og sekreterer proteinet interferon (IFN) som i neste omgang stimulerer produksjon av antivirale proteiner som hemmer virusreplikasjonen. Mx-protein er et av de viktigste IFN-stimulerte antivirale proteinene. I dette mastergradsarbeidet har effekten av ...

Fisheries agreements between EU-Seychelles have been in place since 1984. Since then, the agreements have been in constant changes in response to the constructive criticisms from NGOs and scientists to the CFP. An exploratory study assessing the relationship between the EU-Seychelles Fisheries Agreements has been conducted. It focuses on the changes and the differences between the Fisheries Partnership ...

Marin plastforsøpling er et tema med vind i seilene. Jeg har gjort kvalitative intervjuer med norske og russiske fiskere. Målet har vært å forstå møte mellom hvordan alt oppstyret rundt forsøpling ser ut fra fiskeflåten, og hvordan styring av fiskeriene påvirker atferden i dem. Institusjonell teori er en sentral del av oppgaven. Avfallssproblemet og håndteringen av det er i ferd med å bli ...

ABSTRACT Angola has a very long coastline, and shares the Benguela Current Large Marine Ecosystem (BCLME) with Namibia and South Africa in the SADC region, one of the most productive LME in the world. The fauna is rich in small pelagic species, crustaceans and demersal fish community, explored by the commercial fishery. Understanding governability as a process of finding balance between the ...

Background: Salmon lice (Lepeophtheirus salmonis) is an increasing limiting factor of Atlantic salmon (Salmo salar) aquaculture development in Northern Hemisphere. Different types of treatments have been tested and used to control lice on farmed Atlantic salmon with varying results. The aim of this systematic review is to examine effectiveness expressed as the reduction of the number of lice and ...

This thesis is dedicated to study the main challenges that occurs when a new resource is to be made manageable, in accordance with the Norwegian principles of fisheries management and international obligations and agreements. The research object of this thesis is the snow crab (Chionoecetes opilio), and its current establishment in the Barents Sea. The study is based on theory of governability and ...

I de siste par tiårene har det vært en kraftig økning i humant bruk av kosttilskudd som inneholder langkjedede omega-3 fettsyrer, det vil si eicosapentaensyre (EPA) og docosaheksaensyre (DHA). Årsaken er de antatte positive helseeffekter disse fettsyrene har. I dag er det vanligst at slike kosttilskudd tas i form av kapsler, blant annet fordi mange mennesker synes marine oljer er ubehagelig å drikke ...
