Ambisjoner om videre vekst i norsk havbruksnæring har vært hyppig uttalt, både av næringen selv, og av skiftende regjeringer. Sentralt er at næringen skal gis muligheten til vekst, så lenge det skjer innenfor miljømessige bærekraftige rammer. Dette kan betraktes som en politisk målsetting for norsk havbruksnæring. Men næringens muligheter for vekst avgjøres ikke av politiske målsettinger alene. Andre ...

This paper reviews the bioeconomic literature on habitat-fisheries connections. Many such connections have been explored in the bioeconomic literature; however, missing from the literature is an analysis merging the potential influences of habitat on both fish stocks and fisheries into one general, overarching theoretical model. We attempt to clarify the nature of linkages between the function of ...

Behavioral parameters are reliable and useful operational welfare indicators that yield information on fish health and welfare status in aquaculture. However, aquatic environment is still constraining for some solutions based on underwater cameras or echo sounder transmitters. Thus, the use of bio-loggers internally or externally attached to sentinel fish emerges as a solution for fish welfare ...

Book review of Leena Heinämäkis book from 2010. Rovaniemi: Lapland University Press. 380 p, softcover.

Input and output measures, including the use of (Pigou) taxes, have been recommended to bridge the gap between average and marginal revenues in fisheries. Several countries have improved management, but few have followed the fiscal recommendations. On the contrary, subsidies that can expand capacity and effort have been and still are used. For decades, international organizations such as the WTO, ...

Since 1986, the management of radioactive contamination in food and feed in Norway has been driven mainly by the Chernobyl Disaster follow-up. Monitoring and countermeasures are still in place to reduce the exposure to the population. The Norwegian Food Safety Authority is in the process of revising the maximum levels (MLs) for radioactive substances in drinking water and food and establishing ...

Marine mammals are important players in the Barents Sea ecosystem but their structural role in the foodweb has been little explored. We compare foodweb-related characteristics within and between phylogenetic groups for 19 marine mammals. As a group, they directly connect to the most central species (i.e cod and haddock) in the Barents Sea (i.e. cod and haddock) and consume over half of the available ...

Det er ikke tvil om at røde blodceller er livsviktige, siden de forsyner kroppen med oksygen, og laksens blodceller frakter oksygen kanskje enda mer effektivt enn våre blodceller gjør. Men det er ikke det eneste de røde blodcellene i laksen kan. De har en cellekjerne som kan uttrykke en mengde gener - de har sensorer for virus og stresshormoner og mye mer - og får signaler fra ...

Salmon farming is a rapidly growing industry in the North and its sustainable development depends on adequate governance. We have assessed the governance systems for salmon farming in four northern countries, Canada, the Faroe Islands, Iceland, and Norway. In all the countries, the industry is marked by controversies, linked to the environmental and societal impacts of its activities. The question ...

B cell responses are a crucial part of the adaptive immune response to viral infection. Infection by salmonid alphavirus subtype 3 (SAV3) causes pancreas disease (PD) in Atlantic salmon (<i>Salmo salar</i>) and is a serious concern to the aquaculture industry. In this study, we have used intraperitoneal (IP) infection with SAV3 as a model to characterize local B cell responses in the peritoneal ...
