Changes in circulating insulin-like growth factor-1 and its binding proteins in yearling rainbow trout during spring under natural and manipulated photoperiods and their relationships with gill Na+, K+-ATPase and body size
Cui, Wenda; Takahashi, Eisuke; Morro, Bernat; Vigo, Pablo Balseiro; Albalat, Amaya; Pinto Pedrosa, Cindy; Mackenzie, Simon A.; Nilsen, Tom Ole; Sveier, Harald; Ebbesson, Lars O.E.; Handeland, Sigurd Olav; Shimizu, Munetaka (Journal article; Peer reviewed, 2022)Smoltification in salmonids occurs during spring in response to increasing photoperiod to prepare for marine life. Smoltification is associated with increased hypo-osmoregulatory ability and enhanced growth potential, ... -
The exorhodopsin and melanopsin systems in the pineal complex and brain at early developmental stages of Atlantic halibut (Hippoglossus hippoglossus)
Eilertsen, Mariann; Drivenes, Øyvind; Edvardsen, Rolf; Bradley, Clarissa A.; Ebbesson, Lars O.E.; Helvik, Jon Vidar (Journal article; Peer reviewed, 2014)The complexity of the nonvisual photoreception systems in teleosts has just started to be appreciated, with colocalization of multiple photoreceptor types with unresolved functions. Here we describe an intricate expression ... -
Exposure to cold temperatures differentially modulates neural plasticity and stress responses in post-smolt Atlantic salmon (Salmo salar)
Tang, Patrik Anthony; Stefansson, Sigurd Olav; Nilsen, Tom Ole; Gharbi, Naouel; Lai, Floriana; Tronci, Valentina; Vigo, Pablo Balseiro; Marnix, M.; Ebbesson, Lars O.E. (Journal article; Peer reviewed, 2022)The transfer success of farmed post-smolt Atlantic salmon (Salmo salar) to sea-cages rely on neural adaptions to promote stress resilience. As low temperatures impact physiology, this suggests that off-season transfer to ... -
Impact of fish density and specific water flow on skin properties in Atlantic salmon (Salmo salar L.) post-smolts
Sveen, Lene Rydal; Timmerhaus, Gerrit; Torgersen, Jacob Seilø; Ytteborg, Elisabeth; Jørgensen, Sven Martin; Handeland, Sigurd Olav; Stefansson, Sigurd Olav; Nilsen, Tom Ole; Calabrese, Sara; Ebbesson, Lars O.E.; Terjesen, Bendik Fyhn; Takle, Harald Rune (Peer reviewed; Journal article, 2016)Prolonged production of Atlantic salmon (Salmo salar) post-smolts in closed-containment systems has prompted research into biological requirements under higher production intensities. This study examined the effect of fish ... -
Increased Thermal Challenges Differentially Modulate Neural Plasticity and Stress Responses in Post-Smolt Atlantic Salmon (Salmo salar)
Tang, Patrik Anthony; Gharbi, Naouel; Nilsen, Tom Ole; Gorissen, M.; Stefansson, Sigurd Olav; Ebbesson, Lars O.E. (Journal article; Peer reviewed, 2022)The successful transfer of farmed post-smolt Atlantic salmon (Salmo salar) depends on proper stress responses and cognitive functions during the early seawater (SW) phase. However, with increasing summer oceanic temperatures, ... -
The ontogeny and brain distribution dynamics of the appetite regulators NPY, CART and pOX in larval Atlantic cod (Gadus morhua L.)
Le, Hoang T.M.D.; Angotzi, Anna Rita; Ebbesson, Lars O.E.; Karlsen, Ørjan; Rønnestad, Ivar (Peer reviewed; Journal article, 2016-04-21)Similar to many marine teleost species, Atlantic cod undergo remarkable physiological changes during the early life stages with concurrent and profound changes in feeding biology and ecology. In contrast to the digestive ... -
Stocking density limits for post-smolt Atlantic salmon (Salmo salar L.) emphasis on production performance and welfare
Calabrese, Sara; Nilsen, Tom Ole; Kolarevic, Jelena; Ebbesson, Lars O.E.; Pinto Pedrosa, Cindy; Fivelstad, Sveinung; Hosfeld, Anne-Camilla Diesen; Stefansson, Sigurd Olav; Terjesen, Bendik Fyhn; Takle, Harald Rune; Martins, Catarina I.M.; Sveier, Harald; Mathisen, Frode; Imsland, Albert Kjartanson; Handeland, Sigurd Olav (Peer reviewed; Journal article, 2017-02)For the development of commercial scale semi-closed sea systems for farming post-smolt Atlantic salmon (Salmo salar), further knowledge is required on the interaction between fish density, farming conditions and fish ... -
Transient photoreception in the hindbrain is permissive to the life history transition of hatching in Atlantic halibut
Eilertsen, Mariann; Valen, Ragnhild; Drivenes, Øyvind; Ebbesson, Lars O.E.; Helvik, Jon Vidar (Journal article; Peer reviewed, 2018)In nonmammalian vertebrates, photoreception takes place in the deep brain already early in development, but knowledge is lacking about the functions of these nonvisual photoreceptive systems. Prior to hatching, Atlantic ... -
