Comparing the primary energy and phosphorus consumption of soybean and seaweed-based aquafeed proteins – A material and substance flow analysis
(Journal article; Peer reviewed, 2018)This study compares the environmental performances of two protein sources for aquafeed production: Brazilian soy protein and Norwegian seaweed protein concentrates. The efficiency and sustainability of these two production ... -
Considering elements of natural strategies to control salmon lice infestation in marine cage culture
(Peer reviewed; Journal article, 2022)Salmon lice are a severe problem in salmonid aquaculture and also affect wild salmon smolts migrating through fjord systems in spring. To keep the lice burden within acceptable limits, frequent use of chemical delousing ... -
Consumer acceptance of new food trends resulting from the fourth industrial revolution technologies: A narrative review of literature and future perspectives
(Peer reviewed; Journal article, 2022)The growing consumer awareness of climate change and the resulting food sustainability issues have led to an increasing adoption of several emerging food trends. Some of these trends have been strengthened by the emergence ... -
Depigmentation - Possible causes of change in phenotype, potential genetic mechanisms, and methods for investigating the cause of depigmentation
(Bachelor thesis, 2022)Defekter i pigmentering klassifiseres som enten hypo-, hyper- eller depigmentering. Hypo- og hyperpigmentering er tilstander med henholdsvis redusert og økt mengde pigment. Depigmentering er en tilstand hvor områder av ... -
