Male reproductive biology of European hake Merluccius merluccius
(The University of Bergen, 2010-05-14)
The reproductive biology of European hake (Merluccius merluccius) has been studied extensively in the field, but mainly focusing on fecundity regulation in females and its implications for the fishery. The European hake ...
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, ...
Mechanisms of cataract development in adult Atlantic salmon growers relative to dietary histidine and plant feed ingredients
(The University of Bergen, 2010-03-19)
Cataracts are defined as opacities of the eye lens and can be caused by a large number of risk factors. In aquaculture, cataracts in farmed Atlantic salmon (Salmo salar L.) represent an ethical problem and can cause ...

(The University of Bergen, 2013-12-17)
The Porifera is a very old group of organisms that has been dated back to more than 500 million years. They are important to marine benthic communities by providing protection, contributing to nutrient recycling and ...
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 ...
Is the evolution of clutch size limited by incubation ability in shorebirds?
(The University of Bergen, 2015-06-01)
Incubation is a crucial aspect of avian life history where differences in incubation techniques and investments can have long lasting effects on offspring and parental well- being and reproductive success. The factors ...
