Bioøkonomisk analyse av negative eksternaliteter mellom lakseoppdrettsanlegg
(Masteroppgave/UIS-TN-ISØP/2019;, Master thesis, 2019-06)Norsk oppdrettsnæring har vært en industri i stadig vekst helt frem til 2015, hvor problemer knyttet til blant annet lakselus og sykdom satte en brems på veksten. Næringen har alltid slitt med denne type negative faktorer, ... -
Climate Risk in Norwegian Aquaculture
(Masteroppgave/UIS-HH/2018;, Master thesis, 2018-06)Climate change poses significant challenges on a global scale, and financial impacts could be caused both directly through natural disaster and indirectly through a transition to a lower- carbon economy. Climate change and ... -
Comparative study of circular and square gravity-based fish cages with different dimensions under pure current conditions
(Peer reviewed; Journal article, 2021-12)Two typical gravity-based fish cages with circular and square shapes are modeled in the present study to compare their cage deformations, cultivation volumes and drag forces under different pure current conditions. Two hy ... -
Delivering the Goods: The Determinants of Norwegian Seafood Exports
(Peer reviewed; Journal article, 2020-01)Seafood is the world’s most traded food product. In recent years, aquaculture has become an increasingly important part of seafood production, facilitating increased trade. However, despite evidence that fish farmers have ... -
Dependence of Profitability on Time, Sector & Region across Aquaculture Value Chains in Norway
