min studie vil jeg se på muligheten for å introdusere et nytt lakseprodukt til Japan, Varmrøykt laks. Varmrøkt laks ble valgt som utgangspunkt fordi dette er et bearbeidet lakseprodukt som antatt hadde ingen eller lite anerkjennelse i Japan. Ved å introdusere et bearbeidet lakseprodukt ingen hadde noe forhold til og deretter måle oppfatning av dette produktet, kunne man si noe om mulighetene for ...

Light fishing is one of the most advanced and successful methods in several fisheries worldwide. Light fishing operations in Myanmar involve using light luring methods in inshore and offshore fisheries, especially for catching squids and pelagic fishes in squid seine (stick-held falling net) and purse seine vessels. Technological advancements have led fishers to use more power, light intensity, and ...

Background: The effect of diet on fatty acids in Atlantic salmon, particularly omega-3 long-chain polyunsaturated fatty acids (n-3 LC PUFA), has been understudied due to lack of marine raw materials (fish meal and fish oil). A variety of ingredients are used as replacements for fish meal for Atlantic salmon. The aim of this systematic literature review (SLR) is examining the effect of omega 3 fatty ...

The commercial farming of juvenile lumpfish requires monitoring of gonadal development to achieve synchronized production. Conventional methods such as gonadosomatic index (GSI), sex hormone analyses, gonadal histology, endoscopy, and gene expression analyses are costly, invasive, and often involve sacrificing the fish. We assessed the efficiency of ultrasound as a non-invasive method for monitoring ...

This book is about the on-going transition of fisheries governance and the emergence of research practices and advice frameworks that allow for the co-creation of common knowledge bases for management. This chapter introduces the context under which the GAP project (‘Bridging the gap between science and stakeholders') was conceived, describes its overall approach, orientates the reader to key issues ...

Scientific debates often revolve around the issues of ‘unbiased science’ with the majority of scientists keeping themselves at arm’s length from policy-making to ensure their credibility. Participatory research has been shifting these dynamics and has led to the emergence of research practices and advice frameworks that allow co-creation of common knowledge bases for management. This chapter, following ...

Small-scale fisheries are highly relevant in Norway. Until 1989, small-scale fisheries were open access and, like other Norwegian fisheries, subsidised; since then they have changed radically. The closure of major fisheries in the early 1990s, following collapses in important stocks and the removal of direct subsidies, has affected fisheries of all sizes. Societal changes have also had an impact on ...

Combining Games and Agent-Based Models (ABMs) in a single research design (i.e. GAM design) shows potential for investigating complex past, present, or future social phenomena. Games offer engaging environments that can help generating insights into social dynamics, perceptions, and behaviours, while ABMs support the representation and analysis of complexity. We present here the first attempt to ...

Are there limits to the governability of a fishery? The establishment of a 200 nautical mile economic zone in Norway in 1977 made it possible to change from an open-access regime to a more closed one. In this process, the former self-regulating Norwegian fishing industry, to a large extent, accepted and adapted an explicit, hierarchical form of state-run governance. However, the process of change ...

Heavy metal (Cu, Zn, Cd, Pb and Fe) concentrations in salt marsh sediments of the Karnafully River coast were investigated in this study. Sediment samples of four different sites were analysed for selected heavy metals by AAS (atomic absorption spectrophotometry). The mean values of heavy metals were 45.79 µg/g for Cu, 105.0 µg/g for Zn, 0.43 µg/g for Cd, 26.70 µg/g for Pb and 3297.38 µg/g for Fe ...
