Developments in national fisheries and marine environmental policies during the last 30 years have changed the relationship between coastal communities and the marine resources that people in these communities traditionally harvested. In Norway, for example, when the state authorities have made decisions to defend what they regard as national interests, the local level has been left with authority ...

Warm water treatment has in recent years become widely used for ridding salmonids of sea lice in aquaculture although the consequences of the treatment for fish welfare are not adequately investigated. The objective of this study was to document potential long-term welfare effects of repeated warm water treatments on Atlantic salmon (Salmo salar). Five weeks after a baseline welfare indicator ...

The emergence of drug-resistant bacteria is increasing rapidly in all parts of the world, and the need for new antibiotics is urgent. In our continuous search for new antimicrobial molecules from under-investigated Arctic marine microorganisms, a marine fungus belonging to the family Lulworthiaceae (Lulworthiales, Sordariomycetes, and Ascomycota) was studied. The fungus was isolated from driftwood, ...

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, ...

Norge er verdens største produsent av atlantisk laks og ambisjonene er å femdoble lakseproduksjonen frem mot 2050. Siden 2012 har det ikke vært produksjonsvekst i oppdrettsnæringen som følge av problemer med lakselus og ulike fiskesykdommer. Problemene har tvunget oppdrettsnæringen å tenke i nye baner for å oppnå videre vekst. Siste årene har flere oppdrettsselskap startet utbygging av landbaserte ...

Export–import relationships are very complex and are regulated by different legal instruments. Incoterms 2000 is one of the most important issues in the international seafood trade. Its use varies depending on business environments, countries and companies involved. The most common factors affecting the choice of delivery terms from Incoterms 2000 are volume/value of the consignment, control over ...

Ecosystem-based management presupposes that the state and development trends of an ecosystem - or of ecological quality - can be measured and followed. Currently, in many coastal countries there exists a variety of monitoring practices that are concerned with single issues only, and are not an integrated part of a larger framework. With the trend towards more comprehensive forms of ecosystem-based ...

Agriculture plays vital role in Ethiopian economy. However, despite its importance and potential, the sector has remained at subsistence level. Animal protein is the most deficient nutrient in human diet. One of the traditional sources of animal protein of the developing world is through livestock rearing. Unfortunately, the livestock production is under increasing pressure from the combined effects ...

Fungi are among the most prolific producers of secondary metabolites, many of which have huge utility for society as various anti-infective and anticancer drugs. The genes encoding these secondary metabolites are arranged in continuous biosynthetic gene clusters (BGCs). Each fungus can have tens of different BGCs in its genome, possessing the ability to produce a multitude of secondary metabolites ...
