Additive effects of enhanced ambient ultraviolet B radiation and increased temperature on immune function, growth and physiological condition of juvenile (parr) Atlantic Salmon, Salmo salar
Jokinen, Ilmari E.; Salo, Harri M.; Markkula, Eveliina; Rikalainen, Kaisa; Arts, Michael T.; Browman, Howard I. (Journal article; Peer reviewed, 2010-09-29)Climate change models predict increased ultraviolet B (UVB) radiation levels due to stratospheric ozone depletion and global warming. In order to study the impact of these two environmental stressors acting simultaneously ... -
Early ontogeny of the Atlantic halibut Hippoglossus hippoglossus head
Cloutier, R.; de Souza, J. Lambrey; Browman, Howard I.; Skiftesvik, Anne Berit (Journal article; Peer reviewed, 2011-04-04)An ontogenetic sequence of Atlantic halibut Hippoglossus hippoglossus larvae, reared in intensive culture conditions, was cleared and stained and histologically processed to determine normal cranial chondrification for ... -
Effects of UV Radiation and Diet on Polyunsaturated Fatty Acids in the Skin, Ocular Tissue and Dorsal Muscle of Atlantic Salmon (Salmo salar) Held in Outdoor Rearing Tanks
Arts, Michael T.; Browman, Howard I.; Jokinen, Ilmari E.; Skiftesvik, Anne Berit (Journal article; Peer reviewed, 2010-07)The effect of UV radiation (UVR) on juvenile Atlantic salmon (Salmo salar) was assessed by measuring the fatty acid (FA) profiles of muscle, dorsal and ventral skin, and ocular tissues following 4-month long exposures to ... -
Foraging behaviour of larval cod (Gadus morhua) at low light intensities
Vollset, Knut Wiik; Folkvord, Arild; Browman, Howard I. (Journal article; Peer reviewed, 2011-02-13)The ability to forage at low light intensities can be of great importance for the survival of fish larvae in a pelagic environment. Three-dimensional silhouette imaging was used to observe larval cod foraging and swimming ... -
The three-dimensional prey field of the northern krill, Meganyctiphanes norvegica, and the escape responses of their copepod prey
Abrahamsen, Mari B.; Browman, Howard I.; Fields, David M.; Skiftesvik, Anne Berit (Journal article; Peer reviewed, 2010-02-24)In the north Atlantic, Meganyctiphanes norvegica feeds predominantly on copepods, including Calanus spp. To quantify its perceptual field for prey, and the sensory systems underlying prey detection, the responses of tethered ... -
Welfare of aquatic organisms: Is there some faith-based HARKing going on here?
Browman, Howard I.; Skiftesvik, Anne Berit (Journal article; Peer reviewed, 2011-05-09)Much of the literature on aquatic animal welfare is flawed by 4 non-mutually exclusive (and often inter-related) biases: under-reporting/ignoring of negative results, faith-based research and/or interpretations, Hypothesizing ...
