Instar growth and Development of Lepeophtheirus salmonis Copepodids.
(The University of Bergen, 2009-05-07)
Salmon louse Lepeophtheirus salmonis, (Krøyer, 1837) is a caligid parasite, responsible for major economical loss and welfare issues in Norwegian marine culture of salmonid species. Infections are mainly controlled with ...
Geomicrobial characterisation of a 60 m long permafrost core, taken over a future CO2 storage site at Svalbard
(The University of Bergen, 2014-09-11)
In connection with a planned CO2 storage pilot project in the Arctic, a 60 m long permafrost core was drilled in Adventdalen, Svalbard, representing the poorly studied deep permafrost ecosystems. The on-shore drilling was ...

(John Wiley & Sons, Inc., 2013)
High Arctic Invertebrate Biogeography. Patterns and Colonization Processes since the Last Glacial Maximum
(The University of Bergen, 2011-09-22)
The biogeography of Arctic terrestrial invertebrate species, and particularly processes creating and determining patterns of species distribution, have rarely been considered as a whole, but rather on a regional basis, ...
Microbiological aspects of fish handling and processing in the Norwegian pelagic sector
(The University of Bergen, 2015-03-17)
Most global marine fish resources seem to have reached their limit of sustainable exploitation, whereas the demand for high quality fish products is still increasing. The fish sector needs to comply with the growing market ...
Factors affecting the efficiency and selectivity of the Andaman Sea demersal sampling trawl
(The University of Bergen, 2011-12-05)
The average catch per unit of swept area (CPUE) from bottom trawl surveys by research vessels are used as an index of abundance for the demersal fish resources of the Thai waters of the Andaman Sea. The surveys are ...
Long-term dynamics of wadi trees in a hyper-arid cultural landscape
(The University of Bergen, 2007-03-09)
This study focuses on the long-term dynamics of wadi (dry river valley) trees, in particular Acacia tortilis (Forssk.) Hayne, in the hyper-arid Eastern Desert of Egypt. The project was motivated by the importance of ...
Using behaviour of herring (Clupea harengus L.) to assess post-crowding stress in purse-seine fisheries
(The University of Bergen, 2014-05-30)
Within the purse-seine fishery crowding fish at high densities, during the process of slipping, has been shown to cause high mortalities. Mitigation measures are therefore needed to enable fishermen to avoid slipping fish, ...
Strategies for partition between reproductive investment and body growth in stationary and migratory stocks of Atlantic herring
(The University of Bergen, 2011-06-01)
The present study focused on the trade-off between reproductive investment and body growth of migratory and stationary Atlantic herring (Clupea harengus) populations. Published data from Norwegian spring-spawning (NSS) ...
