摘要:Abstract(#br)From an aquaculture point of view, control of the sexual maturation cycle is critical for a sustainable production of the species. For year-round reliable production of juvenile lumpfish of the appropriate size for stocking salmon cages, there is a need for basi...

摘要:Abstract(#br)The aim of this study was to investigate the effect of continuous light of different duration, applied from late autumn to spring in the second year of the production cycle, on the production performance of Atlantic salmon in Northern Norway. The underlying hypo...

摘要:Abstract(#br)In order to provide year round spawning broodstock, lumpfish (initial size 746 g and 24.9 cm) were reared under four different photoperiod regimes from January 2017 to July 2018. One group was reared under simulated natural photoperiod (LDN, control group) for T...

摘要:Abstract(#br)Two groups of PIT-tagged lumpfish (initial mean weight ± SD, 22.3 ± 2.5 g) were established in land-based tanks. One group received marine pelleted feed (MF group) whilst the other received a mix of pelleted feed, live adult Artemia and frozen sea lice (LF group...

摘要:Abstract(#br)Leptin and ghrelin are important regulators of energy homeostasis in mammals, whereas their physiological roles in fish have not been fully elucidated. In the present study, the effects of leptin and ghrelin on adipogenesis, lipolysis and on expression of lipid ...

摘要:Abstract(#br)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 density and specific water flow on sk...

摘要:Abstract(#br)In recent years rapidly growing research has led to identification of several fish leptin orthologs and numerous duplicated paralogs possibly arisen from the third and fourth round whole genome duplication (3R and 4R WGD) events. In this study we identify in Atl...

摘要:Abstract(#br)Salmonid alphavirus subtype 3 (SAV3) causes pancreas disease (PD) and adversely affects salmonid aquaculture in Europe. A better understanding of disease transmission is currently needed in order to manage PD outbreaks. Here, we demonstrate the relationship betw...

摘要:Abstract(#br)Atlantic salmon ( Salmo salar ) rely on changes in photoperiod for the synchronization of the developmental events constituting the parr–smolt transformation. In the absence of photoperiod cues, parr–smolt transformation is incomplete, and such ‘pseudo-smol...

摘要:Abstract(#br)The 6th International Workshop on Salmonid Smoltification was held in Westport, Ireland, during September 3–7, 2001. Perhaps more so than at past workshops, this meeting took a ‘salmon life cycle’ approach to smoltification. Results presented at the worksho...
