Perspectives on ecosystem-based approaches to the management of marine resources
Wrasse (Labridae) as cleaner fish in salmonid aquaculture – The Hardangerfjord as a case study
(Journal article; Peer reviewed, 2013-10-15)
Several species of wrasse (Labridae) are used as cleaner fish to remove salmon lice from farmed Atlantic salmon. We estimated the fishery and use of wrasse in Hardangerfjord. The estimated numbers of labrids used on salmon ...
Grazing Rates of Calanus finmarchicus on Thalassiosira weissflogii Cultured under Different Levels of Ultraviolet Radiation
(Journal article; Peer reviewed, 2011-10-18)
UVB alters photosynthetic rate, fatty acid profiles and morphological characteristics of phytoplankton. Copepods, important grazers of primary production, select algal cells based upon their size, morphological traits, ...
Effect of Sub-Lethal Exposure to Ultraviolet Radiation on the Escape Performance of Atlantic Cod Larvae (Gadus morhua)
(Journal article; Peer reviewed, 2012-04-19)
The amount of ultraviolet (UV) radiation reaching the earth’s surface has increased due to depletion of the ozone layer. Several studies have reported that UV radiation reduces survival of fish larvae. However, indirect ...
Magnetic Compass Orientation in the European Eel
(Journal article; Peer reviewed, 2013-03-15)
European eel migrate from freshwater or coastal habitats throughout Europe to their spawning grounds in the Sargasso Sea. However, their route (~ 6000 km) and orientation mechanisms are unknown. Several attempts have been ...
Welfare of aquatic organisms: Is there some faith-based HARKing going on here?
(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 ...
Effect of turbulence on the energetics of foraging in Atlantic cod Gadus morhua larvae
(Journal article; Peer reviewed, 2004-11-01)
A net energy gain (NEG) model was used to assess the effects of turbulence on the energy budget of Atlantic cod Gadus morhua larvae, feeding on copepod nauplii at different concentrations. The geometry of their prey search ...
Applications of sensory biology in marine ecology and aquaculture
Politics and socio-economics of ecosystem-based management of marine resources
