Otolith growth across two generations in Atlantic herring (Clupea harengus)
(The University of Bergen, 2018-06-27)The Atlantic herring (Clupea harengus) has a wide distribution and a complex metapopulation structure with interactions between the sub-populations. The sub-populations show different adaptations, both genetic and ...Master thesis -
The impact of micro-mineral sources and their availability on hepatic lipid metabolism in Atlantic salmon (Salmo salar)
(The University of Bergen, 2018-06-27)The increased use of plant-based ingredients in aquafeeds for Atlantic salmon has led to an increase in phytate, an antinutrient binding micro minerals and reducing their bioavailability. It has been suggested that the ...Master thesis -
Forkunnskaper i biologiundervisningen: En kvalitativ studie av læreres begrunnelse for hvorfor og hvordan man kan inkludere elevers forkunnskaper i undervisningen
(The University of Bergen, 2018-06-27)Studien handler om læreres forståelse av temaet forkunnskaper: hvorfor er det viktig å inkludere den kunnskapen elevene besitter, samt metoder for hvordan man kan inkludere denne kunnskapen. Inkludering av forkunnskaper ...Master thesis -
Recreational fishing for Nephrops in Hordaland, Norway - catches and potential mercury intake
(The University of Bergen, 2018-06-26)Few studies provide information about recreational fishing in Norway. As recreational fishing often occurs in areas close to high-density surroundings, possibly affected by environmental pollutants, it is important to ...Master thesis -
Assessment of growth performance and liver lipid accumulation in Atlantic salmon (Salmo salar) fed an insect-based diet
(The University of Bergen, 2018-06-26)Increase in price and reduced availability of fish meal (FM) has caused the aquaculture industry to look at alternative sources for nutrients for feed production. Vegetable protein sources can replace a substantial part ...Master thesis -
Studying the waste recycling potential of naturally occurring polychaetes on benthic trays under a Norwegian fish farm
(The University of Bergen, 2018-06-26)With an increasing salmon industry comes an increasing amount of waste released into the environment, impacting benthic environments in particular. This study investigated the potential of utilizing naturally occurri ...Master thesis -
Can enrichment improve the post-release survival of hatchery-reared Atlantic salmon fry (Salmo salar)? – A field experiment
(The University of Bergen, 2018-06-26)Release of captive-reared fish to supplement reduced, wild populations has become a common tool for conservation and management. Such attempted population enhancements have, however, had limited success, and several ...Master thesis -
