Body size of male Atlantic salmon (<span><i>Salmo salar</i></span> L.) at introduction of a 5‐week <span>LD12</span>:12 winter signal influences their decision to mature early or smoltify Open
Sexual maturation of male Atlantic salmon post‐smolts (‘jacking’) is undesired in aquaculture and seems to occur due to the intensification in modern facilities. Maturation depends on internal and external factors (temperature, photoperiod…
Transcriptome analysis reveals effects of ethynylestradiol and bisphenol A on multiple endocrine and metabolic pathways in the pituitary and liver of female Atlantic cod (Gadus morhua) Open
Introduction The pituitary and liver are among the main sites of action of estrogens in fish. Years of research has shown that xenoestrogens can interfere with functions of estrogens. There is however incomplete understanding of xenoestrog…

DNA, RNA, and prokaryote community sample stability at different ultra-low temperature storage conditions Open
Long-term storage of extracted DNA, RNA, and samples for DNA and RNA extractions is usually done in ultra-low temperature freezers using the standard temperature of −80°C. While this standard was based on the maximum capacity of early gene…
The effect of photoperiod manipulation on Atlantic salmon growth, smoltification and sexual maturation: A case study of a commercial RAS Open
The effect of photoperiod manipulation on growth, smoltification and maturation was assessed in Atlantic salmon through an observational study performed in a commercial RAS facility from June (25.0 ± 11.0 g) to October 2018 (151.1 ± 25.5 g…
Differential Regulation of the Expression of the Two Thyrotropin Beta Subunit Paralogs by Salmon Pituitary Cells In Vitro Open
We recently characterized two paralogs of the thyrotropin (TSH) beta subunit in Atlantic salmon, tshβa and tshβb , issued from teleost-specific whole genome duplication. The transcript expression of tshβb , but not of tshβa , peaks at the …
Environmental and neuroendocrine control of smoltification in long-river (Loire - Allier) Atlantic salmon Open
Smoltification is a metamorphic event in salmon, which initiates downstream migration and pre-adapts juvenile for seawater entry. The PhD aimed at investigating endocrine and environmental regulation of smoltification in the endangered lon…
