The development of early pioneer neurons in the annelid Malacoceros fuliginosus
(Journal article; Peer reviewed, 2020)Background Nervous system development is an interplay of many processes: the formation of individual neurons, which depends on whole-body and local patterning processes, and the coordinated growth of neurites and synapse ... -
Development of flow cytometry-based techniques for assessing microbial inactivation after water disinfection and downstream processes
(Doctoral thesis, 2023-01-17)Overvåking av mikrobiell vitalitet i akvatiske miljøer kan være utfordrende. Flere metoder er tilgjengelig, og Flow cytometri (FCM) analyser er en effektiv måte å få informasjon om mikrobene. Å kombinere ulike liv/død-farginger ... -
Development of infectious cDNA clones of Salmonid alphavirus subtype 3
(Peer reviewed; Journal article, 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 ... -
Development of novel methods to evaluate availability of zinc, selenium and manganese in Atlantic salmon (Salmo salar)
(Doctoral thesis, 2019-06-06)During the recent years, the composition of salmonids diets has changed from the use of mainly marine-based ingredients (e.g. fish meal and fish oil) to an increased use of plant-based ingredients (e.g. soybean meal and ... -
The development of nuclear protein coding genes as phylogenetic markers in bark and ambrosia beetles (Coleoptera: Curculionidae)
(Doctoral thesis, 2018-03-20)Bark and ambrosia beetles are grouped into two different subfamilies (Scolytinae and Platypodinae), within the superfamily Curculionoidea (more than 60,000 described species). These insects constitute a large part (circa ... -
Development of the adaptive immune system in ballan wrasse (Labrus bergylta) and the impact of different start-feed diets
(Doctoral thesis, 2024-01-19)Berggylt (Labrus bergylta) spiser hovedsakelig bløtdyr, pigghuder og krepsdyr, der også ektoparasitter som plukkes fra andre fisker kan nyttes. Denne egenskapen har ført til at berggylt nå er brukt som rensefisk innen ... -
Development of the salmon louse Lepeophtheirus salmonis parasitic stages in temperatures ranging from 3 to 24°C
(Peer reviewed; Journal article, 2019-09-05)The development rate of the salmon louse Lepeophtheirus salmonis is greatly influenced by seawater temperature. This study describes how the growth rate of L. salmonis changes with temperature and identifies the extreme ... -
Development stage distribution as a proxy for feeding success and growth for first feeding Norwegian spring spawning herring larvae
(Journal article; Peer reviewed, 2020)The estimation of growth rates in young herring larvae (Clupea harengus) in the field can be difficult because the primary increments in the otoliths may not be discernible or formed at a daily level. Likewise, the estimation ... -
The developmental basis for the evolution of new morphologies in Spiralia
(Doctoral thesis, 2020-11-20)Spiralia is a clade of bilaterally symmetrical animals, which display an extreme diversity of divergent body plans accompanied by the presence of multiple subclades- specific morphological and developmental characters. ... -
Developmental RNA-Seq transcriptomics of haploid germ cells and spermatozoa uncovers novel pathways associated with teleost spermiogenesis
(Journal article; Peer reviewed, 2022)In non-mammalian vertebrates, the molecular mechanisms involved in the transformation of haploid germ cells (HGCs) into spermatozoa (spermiogenesis) are largely unknown. Here, we investigated this process in the marine ... -
Developmental stages of the ballan wrasse from first feeding through metamorphosis: Cranial ossification and the digestive system
(Journal article; Peer reviewed, 2022)We have described six developmental stages for the ballan wrasse, from the first feeding until the juvenile stage, supported by specific descriptions of cranial ossification, maturation of the digestive tract, and ... -
Diatom frustules as a biomaterial: effects of chemical treatment on organic material removal and mechanical properties in cleaned frustules from two Coscinodiscus species
(Peer reviewed; Journal article, 2016-08)The three-dimensional structure of silica diatom frustules offers a great potential as nanoporous material for several nanotechnological applications, but the starting point for these applications is the ability to obtain ... -
Diel vertical migration and feeding pattern of M. muelleri in Masfjorden in late autumn
(Master thesis, 2009-03-20)The purpose of this study was to investigate diel vertical migration, feeding pattern and diet composition of mesopelagic fish Maurolicus muelleri in Masfjorden in late autumn and compare these with the previous studies. ... -
Diet affects the redox system in developing Atlantic cod(Gadus morhua) larvae
(Peer reviewed; Journal article, 2015-08)The growth and development of marine fish larvae fed copepods is superior to those fed rotifers, but the underlying molecular reasons for this are unclear. In the following study we compared the effects of such diets on ... -
The diet of juvenile Atlantic mackerel (Scomber scombrus) feeding in new northern nursery areas along the Norwegian coast
(Journal article; Peer reviewed, 2022)The North-east Atlantic mackerel stock size increased substantially from 2006–2014 coinciding with high recruitment. This resulted in a pronounced northerly geographic expansion of mackerel, followed by an influx of juvenile ... -
Dietary fatty acids and their ratio: impact on Atlantic salmon health, mineral status and intestinal lipid transport
(Doctoral thesis, 2022-06-30)The rapid growth of the aquaculture industry and the sharp decline of capture fisheries necessitates finding alternative sources for fish oil and fish meal in aquafeeds. However, the inclusion of VOs in aquafeed alters the ... -
Dietary histidine supplementation prevents cataract development in adult Atlantic salmon, Salmo salar L., in seawater
