Effects of seismic shooting on the lesser sandeel (Ammodytes marinus Raitt) - a field study with grab sampling and in situ video observations
(The University of Bergen, 2004)
Seismic shooting with airguns has been conducted continuously in the North Sea for about 40 years. In the past two decades there has been conflicts of interest between Norwegian industrial trawlers fishing for sandeel and ...
Lifespan extension in a semelparous chordate occurs via developmental growth arrest just prior to meiotic entry
It is proposed that the ageing process is linked to signaling from the germline such that the rate of ageing can be adjusted to the state of the reproductive system, allowing these two processes to co-evolve. Mechanistic ...
Characterization of Small, Mononuclear Blood Cells from Salmon Having High Phagocytic Capacity and Ability to Differentiate into Dendritic like Cells
(Public Library of Science, 2012-11-14)
Phagocytes are the principal component of the innate immune system, playing a key role in the clearance of foreign particles that include potential pathogens. In vertebrates, both neutrophils and mononuclear cells like ...
Hypoxia tolerance thresholds for post-smolt Atlantic salmon: Dependency of temperature and hypoxia acclimation
Atlantic salmon (Salmo salar L.) experience periodic drops in dissolved oxygen (O2) inside aquaculture sea cages. In order to evaluate whether fish function or welfare is compromised during such drops in O2 (termed hypoxia), ...
Modeling early life history of cod
(The University of Bergen, 2007-03-02)
Newly hatched Atlantic cod (Gadus morhua) larvae face an uncertain future when they first enter their marine pelagic habitat. Prior to complete yolk absorption, the larvae will have to find food. This process includes ...
Bestandsstudie av breiflabb (Lophius piscatorius L.) langs kysten av Møre og i Nordsjøen
(The University of Bergen, 2003)
CarboSchools - et utvannet klimaprosjekt eller et forbilde for gode feltstudier i biologi. En casestudie av en biologiklasses erfaringer og utbytte knyttet til CarboSchools prosjektet.
(The University of Bergen, 2010-12-20)
Sammendrag Internasjonale undersøkelser som TIMMS og PISA, samt søkertallene til høyere utdannelser har vist en negativ utvikling for realfagene både kunnskapsmessig og rekrutteringsmessig i løpet av 90-tallet og begynnelsen ...
Cladorhizid sponges from hydrothermal vents and cold seeps in the NE Atlantic Ocean
(The University of Bergen, 2009-09-30)
Sponges are known to frequently contain a great number of symbiotic organisms. Symbiosis is also a characteristic trait of vent and seep animals worldwide. Sponges in the deep sea family Cladorhizidae, otherwise also known ...
Ballan wrasse (Labrus bergylta) predation on hatchery reared scallop (Pecten maximus) spat
(The University of Bergen, 2005)
Sea ranching of the great scallop (Pecten maximus) may have a high potential for future aquaculture in Norway. The edible crab (Cancer pagurus) and starfish (Asterias rubens) have been identified as the major predators, ...
Spatial Distribution of Seatrout Spawning and the Effects on Juvenile Abundance in River Teigdalselva, Western-Norway
(The University of Bergen, 2011-06-01)
The spatial distribution of seatrout spawning-grounds, microhabitat features and the resulting juvenile distribution were observed in a typical Western-Norwegian river. A total of 1870 squares within 187 cross-transects ...
