Earlier or delayed seasonal broodstock spawning changes nutritional status and metabolic programming of growth for next-generation Atlantic salmon
Skjærven, Kaja Helvik; Mommens, Maren; Adam, Anne-Catrin; Saito, Takaya; Oveland, Eystein; Espe, Marit (Peer reviewed; Journal article, 2022)Atlantic salmon (Salmo salar) breeding companies depend on changing light, temperature and feeding regimes to achieve new generations outside the natural spawning season. However, there have been few conducted trials ... -
Impact of Antioxidant Feed and Growth Manipulation on the Redox Regulation of Atlantic Salmon Smolts
Yin, Peng; Bjørnsson, Bjørn Thrandur; Fjelldal, Per Gunnar; Saito, Takaya; Remø, Sofie C.; Edvardsen, Rolf Brudvik; Hansen, Tom Johnny; Sharma, Sandeep; Olsen, Rolf Erik; Hamre, Kristin (Peer reviewed; Journal article, 2022)Accumulating evidence indicates a close relationship between oxidative stress and growth rate in fish. However, the underlying mechanisms of this relationship remain unclear. This study evaluated the combined effect of ... -
Intracellular trafficking of fatty acids in the fish intestinal epithelial cell line RTgutGC
Selvam, Chandrasekar; Saito, Takaya; Sissener, Nini; Prabhu, P. Antony Jesu; Sæle, Øystein (Peer reviewed; Journal article, 2022)The shift towards higher inclusion of vegetable oils (VOs) in aquafeeds has resulted in major changes in dietary fatty acid composition, especially increased amounts of monounsaturated fatty acids (MUFAs) and decreased ... -
Metabolic and molecular signatures of improved growth in Atlantic salmon (Salmo salar) fed surplus levels of methionine, folic acid, vitamin B6 and B12 throughout smoltification.
Adam, Anne-Catrin; Saito, Takaya; Espe, Marit; Whatmore, Paul; Fernandes, Jorge Manuel de Oliveira; Vikeså, Vibeke; Skjærven, Kaja Helvik (Peer reviewed; Journal article, 2021)A moderate surplus of the 1C nutrients methionine, folic acid, vitamin B6 and B12 above dietary recommendations for Atlantic salmon has shown to improve growth and reduce hepatosomatic index in the on-growing salt water ... -
Methionine: An Indispensable Amino Acid in Cellular Metabolism and Health of Atlantic Salmon
Espe, Marit; Adam, Anne-Catrin; Saito, Takaya; Skjærven, Kaja Helvik (Peer reviewed; Journal article, 2023)Methionine is an indispensable amino acid with an important role as the main methyl donor in cellular metabolism for both fish and mammals. Metabolization of methionine to the methyl donor S-adenosylmethionine (SAM) has ... -
Micronutrient supplementation affects DNA methylation in male gonads with potential intergenerational epigenetic inheritance involving the embryonic development through glutamate receptor-associated genes
Saito, Takaya; Whatmore, Paul; Taylor, John F.; Fernandes, Jorge Manuel de Oliveira; Adam, Anne-Catrin; Tocher, Douglas R.; Espe, Marit; Skjærven, Kaja Helvik (Peer reviewed; Journal article, 2022)DNA methylation has an important role in intergenerational inheritance. An increasing number of studies have reported evidence of germline inheritance of DNA methylation induced by nutritional signals in mammals. Vitamins ... -
Micronutrient supplementation affects transcriptional and epigenetic regulation of lipid metabolism in a dose-dependent manner
Saito, Takaya; Whatmore, Paul; Taylor, John F.; Fernandes, Jorge Manuel de Oliveira; Adam, Anne-Catrin; Tocher, Douglas R.; Espe, Marit; Skjærven, Kaja Helvik (Peer reviewed; Journal article, 2020) -
Optimising delousing strategies: developing best practice recommendations for maximal efficacy and positive welfare - Final Report
Bui, Samantha; Skern-Mauritzen, Rasmus; Saito, Takaya; Thompson, Cameron (Rapport fra havforskningen;, Research report, 2023)The salmon aquaculture industry currently uses a range of strategies to combat salmon louse epidemics, however acute delousing methods are limited due to poor efficacy, poor welfare and environmental impacts, or potential ... -
Out-of-season spawning affects the nutritional status and gene expression in both Atlantic salmon female broodstock and their offspring
Skjærven, Kaja Helvik; Oveland, Eystein; Mommens, Maren; Samori, Elsa; Saito, Takaya; Adam, Anne-Catrin; Espe, Marit (Peer reviewed; Journal article, 2020)The Atlantic salmon aquaculture industry relies on adjustments of female broodstock spawning season to meet the demand for delivery of embryos outside the natural spawning season. Earlier results from zebrafish have shown ... -
Parental selenium nutrition affects the one-carbon metabolism and the hepatic dna methylation pattern of rainbow trout (Oncorhynchus mykiss) in the progeny
Wischhusen, Pauline; Saito, Takaya; Heraud, Cécile; Kaushik, Sadasivam J.; Fauconneau, Benoit; Prabhu, P. Antony Jesu; Fontagné-Dicharry, Stéphanie; Skjærven, Kaja Helvik (Peer reviewed; Journal article, 2020)Selenium is an essential micronutrient and its metabolism is closely linked to the methionine cycle and transsulfuration pathway. The present study evaluated the effect of two different selenium supplements in the diet of ... -
Seasonal Changes in Photoperiod: Effects on Growth and Redox Signaling Patterns in Atlantic Salmon Postsmolts
Yin, Peng; Saito, Takaya; Fjelldal, Per Gunnar; Björnsson, Björn Thrandur; Remø, Sofie C.; Hansen, Tom Johnny; Sharma, Sandeep; Olsen, Rolf-Erik; Hamre, Kristin (Peer reviewed; Journal article, 2023)Farmed Atlantic salmon reared under natural seasonal changes in sea-cages had an elevated consumption of antioxidants during spring. It is, however, unclear if this response was caused by the increase in day length, ...
