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 ... -
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, ... -
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 ... -
Water Flow Requirements of Post-smolt Atlantic Salmon (Salmo salar L.) Reared in Intensive Seawater Flow-through Systems: A Physiological Perspective
Calabrese, Sara; Imsland, Albert K. D.; Nilsen, Tom Ole; Kolarevic, Jelena; Ebbesson, Lars O.E.; Hosfeld, Camilla Diesen; Fivelstad, Sveinung; Pedrosa, Cindy; Terjesen, Bendik Fyhn; Stefansson, Sigurd O.; Takle, Harald Rune; Sveier, Harald; Mathisen, Frode; Handeland, Sigurd Olav (Journal article; Peer reviewed, 2023)Environmental challenges related to open sea cage production of Atlantic salmon have sparked interest in developing commercial-scale semi-closed sea systems for post-smolt Atlantic salmon (100–1000 g). Determining the ...
