Swimming energetics of Atlantic salmon in relation to extended fasting at different temperatures
Hvas, Malthe (Peer reviewed; Journal article, 2022)Predicted future warming of aquatic environments could make fish vulnerable to naturally occurring fasting periods during migration between feeding and spawning sites, as these endeavours become energetically more expensive. ... -
The gill parasite Paramoeba perurans compromises aerobic scope, swimming capacity and ion balance in Atlantic salmon.
Hvas, Malthe; Karlsbakk, Egil; Mæhle, Stig; Wright, Daniel William; Oppedal, Frode (Journal article; Peer reviewed, 2017)The parasitic amoeba Paramoeba perurans is an aetiological agent of amoebic gill disease (AGD), a serious problem in seawater salmonid aquaculture globally. Other finfish species are also infected and infection events may ... -

Welfare effects of environmental hypercapnia quantified by indicators based on morphology and allostatic load in Atlantic salmon (Salmo salar)
Höglund, Erik; Folkedal, Ole; Aerts, Johan; Hvas, Malthe; Øverli, Øyvind; Mangor-Jensen, Anders; Vindas, Marco A.; Nilsson, Jonatan; Kristiansen, Tore (Peer reviewed; Journal article, 2023)Water supply is a limited resource in most salmon hatcheries, which is compensated by reduced water flow and oxygenation. However, reduced water exchange can lead to accumulation of CO2, resulting in environmental hypercapnia, ... -
What is The Limit of Sustained Swimming in Atlantic Salmon Post smolts?
Hvas, Malthe; Folkedal, Ole; Oppedal, Frode (Peer reviewed; Journal article, 2021)A trend in Atlantic salmon aquaculture is to establish new production sites that are susceptible to extreme weather conditions; however, strong and persistent water currents may compromise fish welfare. Defining acceptable ...
