The fate of vitellogenic follicles in experimentally monitored Atlantic cod Gadus morhua (L.): Application to stock assessment
(Journal article; Peer reviewed, 2010-05)In this paper we report on the fate of vitellogenic follicles (VF) as either alpha atretic follicles (αF) or post-ovulatory follicles (POFs) using histology and captive Atlantic cod (Gadus morhua) in three experiments. In ... -
Feeding preference of recaptured Atlantic salmon Salmo salar following simulated escape from fish pens during autumn
(Journal article; Peer reviewed, 2010-12-21)Escapes of farmed fish from coastal farms around the world are believed to have genetic and ecological consequences for wild fish populations. Each year there are numerous escapes of adult farmed Atlantic salmon Salmo ... -
Forensic identification of severely degraded Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) tissues
(Journal article; Peer reviewed, 2010-11-03)Aquaculture is a globally important and rapidly growing industry. It contributes positively to the economy and sustainability of coastal communities, but it is not without regulatory challenges. These challenges are diverse, ... -
Genomic organization and gene expression of the multiple globins in Atlantic cod: conservation of globin-flanking genes in chordates infers the origin of the vertebrate globin clusters
(Journal article; Peer reviewed, 2010-10-20)Background: The vertebrate globin genes encoding the α- and β-subunits of the tetrameric hemoglobins are clustered at two unlinked loci. The highly conserved linear order of the genes flanking the hemoglobins provides a ... -
Investigating the drivers of maturation dynamics in Barents Sea haddock (Melanogrammus aeglefinus)
(Journal article; Peer reviewed, 2011-08)Changes in size and age at maturation of many exploited fish stocks have been investigated and the influences of environmental factors and exploitation have often been inferred, but not explicitly investigated. Here we ... -
Learning and anticipatory behaviour in a “sit-and-wait” predator: the Atlantic halibut
(Journal article; Peer reviewed, 2010-03)We studied the learning capacities and anticipatory behaviour in a “sit-and-wait” predatory fish, the Atlantic halibut, Hippoglossus hippoglossus. In Experiment 1 two groups of halibut received series of light flashes ... -
Long-term changes in the total egg production of Norwegian spring-spawning herring Clupea harengus (L.)—Implications of variations in population structure and condition factor
(Journal article; Peer reviewed, 2010-05)The reproductive potential of Norwegian spring-spawning herring (Clupea harengus) was estimated in terms of total egg production (TEP) for the period 1935–2005, using a model where spawning stock numbers (SSN)-, weight- ... -
Marine indikatorer
(DN-utredning;4-2010, Chapter, 2010-09)The Nature Index (NI) is established to get an overview of the state and development of biodiversity within the major ecosystems of Norway. It includes marine, limnic and terrestrial ecosystems. The aim of the index is to ... -
Mechanisms regulating oocyte recruitment and skippedspawning in Northeast Arctic cod (Gadus morhua L.)
(Journal article; Peer reviewed, 2009-09)To examine mechanisms that affect fecundity, atresia and skipped spawning in Northeast Arctic cod (Gadus morhua L.), we conducted an experiment where wild-caught cod (>60 cm) kept under restricted food regimes were subjected ... -
Mortality of mackerel (Scomber scombrus L.) after pursing and slipping from a purse seine
(Journal article; Peer reviewed, 2010-10)A new method was used to study the effect of crowding and subsequent slipping from a purse seine on the mortality of Atlantic mackerel (Scomber scombrus L.). Mackerel were allowed to swim from a purse seine through a ... -

RNA deep sequencing of the Atlantic cod transcriptome
(Journal article; Peer reviewed, 2010-05-20)The Atlantic cod (Gadus morhua) is an emerging aquaculture species. Efforts to develop and characterize its genomic recourses, including draft-grade genome sequencing, have been initiated by the research community. The ... -
Stereological calibration of the profile method to quickly estimate atresia levels in fish
(Journal article; Peer reviewed, 2010-05)The (physical) ‘disector method’, a frequently cited stereological technique, has so far received little attention within fish fecundity studies, although it can be used to provide unbiased, assumption-free data on levels ... -

Tenacibaculum sp. associated with winter ulcers in sea-reared Atlantic salmon Salmo salar
(Journal article; Peer reviewed, 2011-05-09)Coldwater-associated ulcers, i.e. winter ulcers, in seawater-reared Atlantic salmon Salmo salar L. have been reported in Norway since the late 1980s, and Moritella viscosa has been established as an important factor in ... -
The genome sequence of Atlantic cod reveals a unique immune system
(Journal article; Peer reviewed, 2011-08-10)Atlantic cod (Gadus morhua) is a large, cold-adapted teleost that sustains long-standing commercial fisheries and incipient aquaculture. Here we present the genome sequence of Atlantic cod, showing evidence for complex ... -
Thermal niche of Atlantic cod Gadus morhua: limits, tolerance and optima
(Journal article; Peer reviewed, 2010)Recent studies in the marine environment have suggested that the limited phenotypic plasticity of cold-adapted species such as Atlantic cod Gadus morhua L. will cause distributions to shift toward the poles in response to ... -
Viral Haemorrhagic Septicemia (VHS) in wild and farmed fish in Norwegian waters
(Conference object, 2011-05)Viral Haemorrhagic septicaemia viruses (VHSV) are isolated from 82 different fish species and are globally spread in freshwater as well as marine environments. The virus can cause disease outbreaks both in wild and ...
