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, ... -
Endoplasmic reticulum stress as a key mechanism in stunted growth of seawater rainbow trout (Oncorhynchus mykiss)
Morro, Bernat; Broughton, Richard; Vigo, Pablo Balseiro; Handeland, Sigurd Olav; Mackenzie, Simon A.; Doherty, Mary K.; Whitfield, Phillip D.; Shimizu, Munetaka; Gorissen, Marnix; Sveier, Harald; Albalat, Amaya (Journal article; Peer reviewed, 2021)Background Rainbow trout (Oncorhynchus mykiss) is a salmonid species with a complex life-history. Wild populations are naturally divided into freshwater residents and sea-run migrants. Migrants undergo an energy-demanding ... -
Exploring the impact of thermal delousing on gill health and microbiome dynamics in farmed Atlantic Salmon
Elsheshtawy, Ahmed; Clokie, Benjamin Gregory James; Albalat, Amaya; Nylund, Are; Kvåle, Birgit Lilletveit; Andersen, Linda; Moore, Lindsey; Mackenzie, Simon A. (Journal article; Peer reviewed, 2024)The economic cost of salmon louse (Lepeophtheirus salmonis and Caligus rogercresseyi) infestations in the Atlantic salmon (Salmo salar) industry has been estimated to be around $900 million annually. This high cost has ... -
Optimization of Low-Biomass Sample Collection and Quantitative PCR-Based Titration Impact 16S rRNA Microbiome Resolution
Clokie, Benjamin Gregory James; Elsheshtawy, Ahmed; Albalat, Amaya; Nylund, Are; Beveridge, Allan; Payne, Chris J.; Mackenzie, Simon A. (Journal article; Peer reviewed, 2022)The major aquatic interface between host and environment in teleost finfish species is the gill. The diversity of this infraclass, high complexity of the organ, and its direct exposure to the surrounding environment make ...
