Effects of temperature and feeding regime on cortisol concentrations in scales of Atlantic salmon post-smolts
(Peer reviewed; Journal article, 2023)Anadromous fish are vulnerable to anthropogenic and environmental stressors including pollution, rising temperatures, and changes in food availability. Knowledge of how fish respond to specific stressors aid our understanding ... -
Is it possible to photoperiod manipulate spawning time in planktivorous fish ? A long-term experiment on Atlantic herring
(Peer reviewed; Journal article, 2022)The oocyte development (vitellogenesis) of individual fish is highly dependent upon their physiology which is influenced by both intrinsic and extrinsic factors. Thus, if individuals encounter poor biophysical conditions, ... -
Orientation behavior and swimming speed of Atlantic herring larvae (Clupea harengus) in situ and in laboratory exposures to rotated artificial magnetic fields
(Peer reviewed; Journal article, 2020) -
Parasite development affect dispersal dynamics; infectivity, activity and energetic status in cohorts of salmon louse copepodids
(Peer reviewed; Journal article, 2020)The salmon louse, Lepeophtheirus salmonis, is a parasitic copepod infecting wild and farmed salmonid fishes in the northern hemisphere. It has a direct lifecycle with a planktonic dispersal phase and an infective copepodid ... -
Predation mortality from ambush and cruising predators on newly-settled 0-group gadoids
(Peer reviewed; Journal article, 2020)We investigated predation from an ambush predator (shorthorn sculpin) and two cruising predators (Atlantic cod and saithe) on bottom-settled 0-group cod and saithe juveniles in a fjord in northern Norway. Stomach contents ... -
Resistant calcification responses of Arctica islandica clams under ocean acidification conditions
(Peer reviewed; Journal article, 2023)Ocean acidification (OA) directly impacts marine calcifying organisms including ecologically and commercially important shellfish species such as Arctica islandica (A. islandica). To test whether documented growth resilience ... -
Synergism between cruising cod and ambush sculpin predators on 0-group gadoids is modified by daylight cycle and presence of aggressive wolffish
(Peer reviewed; Journal article, 2020)Shorthorn sculpin (Myoxocephalus scorpius) and large cod (300–400 g body weight) are important predators on newly settled 0-group cod (Gadus morhua) and saithe (Pollachius virens) in Porsangerfjorden in northern Norway. ... -
The effect of nutritional condition by two nucleic acid derived indices on the growth to post-flexion of Atlantic bluefin tuna and Atlantic bonito larvae
(Journal article; Peer reviewed, 2019)Notochord flexion increases the swimming capacity of fish larvae, aids in the capture of mobile prey, and coincides with the timing of when the physiological capacities of larvae begin to develop significantly, allowing ...
