Caligus elongatus and other sea lice of the genus Caligus as parasites of farmed salmonids: A review
Hemmingsen, Willy; MacKenzie, Ken; Sagerup, Kjetil; Remen, Mette; Bloch-Hansen, Karin; Imsland, Albert (Journal article; Peer reviewed, 2020)This review was prompted by reports of unusually large numbers of sea lice tentatively identified as Caligus elongatus infesting farmed salmon in northern Norway. Following a brief introduction to the sea lice problem in ... -
Changes in water temperature and oxygen: the effect of triploidy on performance and metabolism in large farmed Atlantic salmon
Sambraus, Florian; Remen, Mette; Olsen, Rolf Erik; Hansen, Tom Johnny; Waagbø, Rune; Torgersen, Thomas; Lock, Erik-Jan; Imsland, Albert; Fraser, Thomas W.K.; Fjelldal, Per Gunnar (Peer reviewed; Journal article, 2018)In salmon farming, the use of sterile triploids (3N) can mitigate the problem of escapees interbreeding with wild salmon. However, triploid salmon appear less tolerant to high water temperatures and low oxygen levels ... -
Hypoxia tolerance thresholds for post-smolt Atlantic salmon: Dependency of temperature and hypoxia acclimation
Remen, Mette; Oppedal, Frode; Imsland, Albert K.; Olsen, Rolf Erik; Torgersen, Thomas (Journal article, 2013-12-05)Atlantic salmon (Salmo salar L.) experience periodic drops in dissolved oxygen (O2) inside aquaculture sea cages. In order to evaluate whether fish function or welfare is compromised during such drops in O2 (termed hypoxia), ... -
The oxygen requirement of Atlantic salmon (Salmo salar L.) in the on-growing phase in sea cages
Remen, Mette (Doctoral thesis, 2012-10-30)Atlantic salmon aquaculture is a successful and growing industry, with a global production of more than 1.4 million tonnes in 2010. In the on-growing phase, Atlantic salmon are normally kept in sea cages, where both the ... -
Possible use of lumpfish to control Caligus elongatus infestation on farmed Atlantic salmon: A mini review
Imsland, Albert; Remen, Mette; Bloch-hansen, karin; Sagerup, Kjetil; Mathisen, Remi; Myklebust, Elisabeth A.; Reynolds, Patrick (Journal article; Peer reviewed, 2020)In this mini review, we systematized current knowledge about the number of Caligus elongatus on farmed Atlantic salmon in relation to the use of lumpfish as cleaner fish. The review was prompted by reports of an unusually ... -
Production performance of Atlantic salmon post-smolts in cyclic hypoxia, and following compensatory growth
Remen, Mette; Aas, Turis Synnøve; Vågseth, Tone; Torgersen, Thomas; Olsen, Rolf Erik; Imsland, Albert; Oppedal, Frode (Peer reviewed; Journal article, 2014-07)This study investigated the production performance of the Atlantic salmon postsmolt (Salmo salar L.) subjected to cyclic oxygen reductions (hypoxia) of varying severity. Triplicate groups (N = 955) were kept at constant ... -
Temperature and size-dependency of lumpfish (Cyclopterus lumpus) oxygen requirement and tolerance
Remen, Mette; Nes, Armand Moe; Hangstad, Thor Arne; Geraudie, Perrine; Reynolds, Patrick; Urskog, Tonje Cecilie; Hanssen, Anna; Stefansson, Sigurd Olav; Imsland, Albert (Journal article; Peer reviewed, 2022)Lumpfish are currently produced and utilized as cleaner fish, to control sea lice infestation rates in salmon net pens, but information on environmental requirements is still limited. This study aimed to determine the zone ...
