Lumpfish (Cylcopterus lumpus) is increasingly used as cleaner fish in intensive farming of Atlantic salmon (Salmo salar) with an aim to control the infection of lice on the salmon. The lumpfish is itself exposed to a number of infections, both bacterial, viral, parasitic and fungal, and there is still a lack of knowledge regarding these infections and their impact on the fish. In order to assess the ...

The Norwegian aquaculture industry is today experiencing increasing demands of Atlantic salmon (Salmo salar L.) from global markets. However, past years has not seen the same rise in production as in value. In a time where several area and environmental-related challenges are hindering further growth of the Norwegian aquaculture industry, the development licenses have become the latest licensing ...

This master thesis will consider the institutional aspects of traditional fisheries regulation among the small Indigenous minorities of the North, Siberia and the Far East of Russia, using the Kola Sámi settled in Murmansk region as case. The thesis studies the potential for influence of local institutions on the traditional fisheries management. Based on documents and internet sources the thesis ...

Cold water species living at high latitudes are expected to respond rapidly to climate change due to their sensitivity to increasing temperature. Water temperature strongly affects the ecology of fish, influencing food intake and conversion, and ultimately somatic growth rate. In a lake, somatic growth rates will also be contingent on food availability, which is negatively affected by fish abundance. ...

Over the last 50 years, the management needs of the Norwegian aquaculture industry have become increasingly complex. The stakeholders in the management vary diversely from environmental agencies and NGOs, to local and national governmental bodies, to those operating the farms themselves. Consequently, the establishment of the Traffic Light System as a management tool has been a long and challenging ...

Det er en økende bekymring for at antibiotikaene vi har tilgjengelige i dag ikke vil være effektive mot humane patogener grunnet resistensutvikling. WHO har uttalt at en pre-antibiotika tid der vanlige infeksjoner og mindre skader kan drepe, er en reell virkelighet i det 21. århundre. Havet dekker over 70% av jordoverflaten, og det er estimert at mellom 50 og 80% av alle arter lever i havet. Organismer ...

The growing Atlantic salmon (Salmo salar) aquaculture production is confronted with many challenges that limit the potential development of the industry. The major current problem threatening the salmon aquaculture production is the parasitic sea lice (Lepeophtheirus salmonis) that negatively affects both cultured salmon and wild stock populations. Several treatment options have failed to deliver ...

Cyanobacteria are a unique source of natural products, where most of them are synthesized by non-ribosomal peptide synthase, polyketide synthase, or a hybrid of these pathways. The identification of such biosynthetic genes responsible for the production of secondary metabolites is still a relatively unexplored area, and it remains many natural products for which a biosynthetic origin is unknown. ...

Nye metoder for å smoltifisere lakseunger er stadig vanligere. Den klassiske metoden er å regulere daglengde for å simulere en naturlig sesongrytme, mens det i dag blir vanligere å tilføre salt i ferskvann- og/eller fôr for å stimulere smoltifisering. Samtidig vil aktører ha settefiskperioden lengere slik at smolten er større ved utsett. Bruk av disse metodene anses å bidra til raskere smoltifisering, ...

Sammendrag Denne masteroppgaven omhandler innovasjon i klyngeprosjekt i distriktene. Formålet med denne oppgaven var å forstå hvilke faktorer som fremmer innovasjon i slike klyngeprosjekt. I mitt teoretiske rammeverk har jeg benyttet Joseph Schumpeters innovasjonsteori, samt innovasjonsteori av Larry Keeley (m, flr.) og av Francis & Bessant. Som hovedteori i har jeg valgt Michael Porters klyngeteori. ...
