Catch me if you can: How to recapture lumpfish using light as an attractant
Foss, Atle; Imsland, Albert; Roth, Bjørn; Nytrø, Ane Vigdisdatter (Journal article; Peer reviewed, 2020)The use of lumpfish in salmon farming allows the removal of sea lice all year round, without the use of chemicals or mechanical treatments. In Norway alone, around 31 million lumpfish are currently put into sea pens whereas ... -
The effect of alternate-day feeding on growth and feed conversion in Atlantic cod Gadus morhua
Bjørnevik, Marit; Imsland, Albert K. D.; Hanssen, Henriette; Roth, Bjørn; Vikingstad, Erik; Foss, Atle (Journal article; Peer reviewed, 2021)This study aimed to investigate the effect of alternating feeding (Alt) compared with control being fed every day (Con) in the on-growth face of Atlantic cod. Individually marked fish (198 and 98 in the Con and Alt groups, ... -
Effects of altered photoperiod regimes during winter on growth and gonadosomatic index in Arctic charr (Salvelinus alpinus) reared in freshwater
Foss, Atle; Siikavuopio, Sten Ivar; Imsland, Albert (Peer reviewed; Journal article, 2020)The short- and long-term effects of altered photoperiods during winter on growth and final gonadosomatic index (GSI) were investigated in 178 individually tagged 2-year-old smolt Arctic charr from an anadromous strain. The ... -
Effects of short-term starvation periods on flesh quality in Arctic charr (Salvelinus alpinus) in different seasons
Imsland, Albert K.D.; Roth, Bjørn; Christensen, Line Bach; Siikavuopio, Sten Ivar; Foss, Atle (Journal article; Peer reviewed, 2020)Possible effects of short‐term starvation on flesh quality in Arctic charr were studied in spring (March) and summer (August). Groups of juvenile Arctic charr (mean weight March 536 g ± 24; August 461 g ± 15 SEM) were ... -
The influence of anaerobic muscle activity, maturation and season on the flesh quality of farmed turbot
Roth, Bjørn; Imsland, Albert K.; Stien, Lars Helge; Schelvis-Smit, Rian; Gunnarsson, Snorri; Foss, Atle (Peer reviewed; Journal article, 2010-04-26)In order to test seasonal, rearing, maturing and anaerobic muscle activity effect on the flesh quality of turbot (Scophthalmus maximus) a total of 80 farmed turbot from three different strains from reared under natural or ... -
Physiological effects of recapture and transport from net-cages in lumpfish
Foss, Atle; Imsland, Albert (Journal article; Peer reviewed, 2022)Lumpfish are widely used for removing sea lice in salmonid sea-based aquaculture. If these fish are to be harvested and used for human consumption, it is necessary to know how the physical strain associated with removing ... -
Physiological response of temperature shocks in turbot and sole
Foss, Atle; Imsland, Albert; van de Vis, Hans; Abbink, Wout; Lambooij, Bert; Roth, Bjørn (Peer reviewed; Journal article, 2019)In the present study, selected temperature drops were examined to investigate the effects of live chilling on stress and welfare in turbot and sole. This study demonstrated that rapid temperature drops from 11°C–12°C and ... -

Stepwise temperature regulation and its effect on growth, feeding and muscle growth patterns of juvenile Atlantic halibut (Hippoglossus hippoglossus L.)
Larsen, Sondre V.; Imsland, Albert K.; Lohne, Petter; Pittman, Karin; Foss, Atle (Peer reviewed; Journal article, 2010)To investigate the possible direct effect of a stepwise reduction in temperature with increasing size on growth, feeding parameters and muscle growth patterns of juvenile Atlantic halibut (Hippoglossus hippoglossus L.), ... -
Stocking density and its influence on the productivity of red cusk eel, Genypterus chilensis (Guichenot, 1848), in shallow raceways
Foss, Atle; Imsland, Albert; Briceño, Felipe A.; Magnolfi, Spartaco; Magnolfi, Piero; Gutiérrez, Xavier (Journal article; Peer reviewed, 2020)We compared the growth properties of red cusk eel Genypterus chilensis with initial mean weight ± standard error, 106.2 ± 6.1 g reared in shallow raceways at three different stocking densities (28.5, 46.1, and 60.7 kg m-3) ...
