However, triploid salmon appear less tolerant to high water temperatures and low oxygen levels ... -
Chemical characterization of 21 species of marine macroalgae common in Norwegian waters: benefits of and limitations to their potential use in food and feed
Biancarosa, Irene; Belghit, Ikram; Bruckner, Christian Guido; Liland, Nina Sylvia; Waagbø, Rune; Amlund, Heidi; Heesch, Svenja; Lock, Erik-Jan (Peer reviewed; Journal article, 2018-01-18)BACKGROUND: In the past few years, much effort has been invested into developing a new blue economy based on harvesting, cultivating and processing marine macroalgae in Norway. Macroalgae have high potential for a wide ... -
Dietary histidine supplementation prevents cataract development in adult Atlantic salmon, Salmo salar L., in seawater
Waagbø, Rune; Tröße, Christiane; Koppe, Wolfgang; Fontanillas, Ramon; Breck, Olav (Peer reviewed; Journal article, 2010-11)The aim of the present study was to investigate the cataract preventive effect of dietary histidine regimes in adult Atlantic salmon (Salmo salar L.) in seawater, both through manipulating the dietary histidine level and ... -
Dietary selenium required to achieve body homeostasis and attenuate pro-inflammatory responses in Atlantic salmon post-smolt exceeds the present EU legal limit
Prabhu, P. Antony Jesu; Holen, Elisabeth; Espe, Marit; Silva, Marta Sofia; Holme, May-Helen; Hamre, Kristin; Lock, Erik-Jan; Waagbø, Rune (Journal article; Peer reviewed, 2020)Selenium (Se) supplementation either as inorganic or organic form was evaluated in Atlantic salmon post-smolt in vivo and in vitro. The basal diet was formulated to be low in fish meal and contain 0.24 mg Se kg−1; six other ... -
