Feeding behavior and bioenergetic balance of the great scallop (Pecten maximus) and the blue mussel (Mytilus edulis) in a low seston environment and relevance to suspended shellfish aquaculture.
(The University of Bergen, 2009-11-20)
The length of the rugged Norwegian coastal line including all islands exceeds the circumference of the earth, and the coastal zone contains many sheltered areas that are potentially suitable for bivalve farming. However, ...
Salamonid alphavirus (SAV) - genetic characterisation of a new subtype, SAV3, and implementation of a novel diagnostic method
(The University of Bergen, 2006-12-13)
Recruitment processes in West Greenland waters : with special focus on Greenland halibut (Reinhardtius hippoglossoides, W.)
(The University of Bergen, 2007-10-19)
The topic of this thesis is recruitment processes in Greenland Halibut (Reinhardtius hippoglossoides) in West Greenland waters. The focal point is Greenland halibut’s early life history from oocytes in the female ovary ...
The oxygen requirement of Atlantic salmon (Salmo salar L.) in the on-growing phase in sea cages
(The University of Bergen, 2012-10-30)
Atlantic salmon aquaculture is a successful and growing industry, with a global production of more than 1.4 million tonnes in 2010. In the on-growing phase, Atlantic salmon are normally kept in sea cages, where both the ...
Effect of different filter methods on water quality to a marine scallop hatchery
(The University of Bergen, 2010-05-31)
Water quality in marine hatcheries is a critical aspect in the production of spat. Different filtering methods have been used to treat the intake seawater in the hatcheries. The Scalpro AS hatchery uses two different types ...
Stress Response and Recovery in Atlantic Salmon (Salmo salar L.) Fed Diets Low in the Marine n-3 Fatty Acids EPA and DHA
(The University of Bergen, 2014-06-01)
With the fast growth of today's aquaculture industry, the demand for aquafeeds is expanding dramatically. Finding sustainable alternative sources to fishmeal and fish oil (FO) is becoming an urgent issue; vegetable oil ...
The interaction between water currents and salmon swimming behaviour in sea cages
(Public Library of Science, 2014-05-15)
Positioning of sea cages at sites with high water current velocities expose the fish to a largely unknown environmental challenge. In this study we observed the swimming behaviour of Atlantic salmon (Salmo salar L.) at a ...
Does snail grazing affect growth of the old forest lichen Lobaria pulmonaria?
(Cambridge University Press, 2006)
Grazing marks from snails are frequently observed in populations of the old forest epiphyte Lobaria pulmonaria. However, grazing marks are more numerous in thalli from deciduous broadleaved forests than in thalli from ...
Development of infectious cDNA clones of Salmonid alphavirus subtype 3
(BioMed Central, 2010-09-21)
Background: Salmonid alphavirus (SAV) is a widespread pathogen in European aquaculture of salmonid fish. Distinct viral subtypes have been suggested based on sequence comparisons and some of these have different geographical ...
