Eggkvalitet er definert som evnen et egg har til å bli befruktet og utvikles til et normalt embryo. Dårlig eggkvalitet kan føre til problemer med aktivering/befruktning eller senere stoppe embryonalutviklingen. Eggkvalitet baseres i hovedsak på egenskaper fra moren (maternale faktorer), men ytre faktorer kan påvirke eggkvaliteten. I kommersiell stamfiskproduksjon av Atlantisk laks (Salmo salar L.) ...

I hvilken grad får lang tids bruk betydning ia dganegne til marine ressurser og i allokeringen av ressurser mellom konkurrerende stater?

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 ...

Evidence-informed decision-making is in increasing demand given growing pressures on marine environments. A way to facilitate this is by knowledge exchange among marine scientists and decision-makers. While many barriers are reported in the literature, there are also examples whereby research has successfully informed marine decision-making (i.e., ‘bright-spots’). Here, we identify and analyze 25 ...

Basert på en dyptgående studie av åtte betydningsfulle importselskaper, analyserer denne masteroppgaven beslutningskriteriene til innkjøperne ved deres valg av produkter og leverandører med et spesielt henblikk til produktet norsk sild. Studien har en kvalitativ og eksplorerende forskningsstrategi. Med basis i grunnleggende markedsføringsteori og spesifikk litteratur om importøradferd, blir det ...

Three wild-caught female harp seals (Pagophilus groenlandicus) from the Greenland Sea stock were brought into temporary captivity in connection with a controlled validation study on energetics. The two pups and one adult were kept in two indoor and outdoor experimental facilities approved by the Norwegian Animal Research Authority. They were trained daily using operant conditioning to participate ...

Coastal fisheries resources play a crucial role in promoting food security and incomes throughout the world. In recent years there has been important concerns all over the world about the overexploitation of wild fish stocks. In many developing coastal countries this overexploitation has been attributed to the increasing demand of fish products and exacerbated by modernization and development of new ...
