  1. 1. Development of osmo- and appetite regulation during transfer of smolt from freshwater to increasing salinities

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Jonna Hellesten; [2023-01-26]
    Nyckelord :;

    Sammanfattning : Atlantic salmon (Salmo salar) is common in Scandinavian aquaculture and must be transferred from freshwater to seawater to grow properly. Despite being assessed as ready smolts, meaning they have gone through the physiological changes to prepare for SW transfer, the transfer result in a mortality rate of around 13-19%, and significant appetite- and growth reductions.

  5. 4. STARTING FROM THE BOTTOM: USING LOW TROPHIC SPECIES IN SALMON FEEDS. Assessing the environmental performance of novel salmon feeds with LCA .

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Moritz Hempel; [2022-08-30]
    Nyckelord :LCA; Salmon aquaculture; novel feeds; seaweed; blue mussel;

    Sammanfattning : Over the past 30 years, the formulation of salmon feeds has shifted from being based on marine ingredients like fishmeal and fish oil towards more plant-based ingredients. This shift was caused by limited supply of wild fish and general sustainability concerns related to using forage fish for feed, so they were mainly replaced with vegetable-protein. LÄS MER
