Habitat associations of juvenile Atlantic cod (Gadus morhua L.) and sympatric demersal fish communities within shallow inshore nursery grounds
(Peer reviewed; Journal article, 2022)Resolving the relationship between demersal fish and sublittoral biotic habitats and substrates is a key element in the protection of important nursery grounds for strengthening fish recruitment. In Norway, coastal Atlantic ... -
Habitat Attributes Dictate the Roles of Dispersal and Environmental Filtering on Metacommunity Assembly at Coastal Soft‑Bottom Ecosystems
(Peer reviewed; Journal article, 2022)Tracking the effects of habitat attributes on species distribution is pivotal to the understanding of community assembly across space and time. We used the elements of metacommunity (EMS), which evaluates coherence, turnover, ... -
Habitat choice by marine zooplankton in a high-latitude ecosystem
(Journal article; Peer reviewed, 2008-07-29)According to habitat choice theory, zooplanktonic prey should choose a depth habitat that maximizes food intake while minimizing predation risk. Body size affects competitive ability and vulnerability in zooplankton, ... -
Habitat configurations shape the trophic and energetic dynamics of reef fishes in a tropical–temperate transition zone: implications under a warming future
(Peer reviewed; Journal article, 2022)Understanding the extent to which species’ traits mediate patterns of community assembly is key to predict the effect of natural and anthropogenic disturbances on ecosystem functioning. Here, we apply a trait-based community ... -
Habitat discontinuities separate genetically divergent populations of a rocky shore marine fish

Habitat selection and competition amongst 0-group gadidae off Mid-Norway
(Working paper, 1988)Juvenile gadids and other co-occurring fishes were collected during August in the years 1981 to 1983 at the Møre coast (Mid-Norway). The gears used were pelagic trawl, bottom trawl, Danish seine and beach seine. All species ... -
Habitat selection and inter year class interactions of young cod (Gadus morhua) in aquaria. In: Flødevigen rapportserie no 1, 1987
(Flødevigen rapportserie, Research report, 1987)Groups of five small (12 - 18 cm) cod were kept in aquaria with two compartments, one with sand and one with stones and algae. When alone, the small fish usually spent most of the time in the compartment with stones and ... -
Habitat selection of juvenile cod (Gadus morhua), whiting (Merlangus merlangius) and some littoral fish in an aquarium. In: Flødevigen rapportserie no 1, 1987
(Flødevigen rapportserie, Research report, 1987)Experiments were conducted to study the habit at selection of juvenile cod Gadus morhua, juvenile whiting merlangus merlangius, black goby Gobius niger, great pipefish Syngnathus acus, sand eel Ammodytes tobianus, ... -
Habitat use and growth of yellow-stage European eel in coastal and freshwater ecosystems in Norway
(Peer reviewed; Journal article, 2022)Many anguillid eel species display facultative catadromy. Some eel spend their entire life cycle in marine coastal areas, but the geographical extent of this, especially at the extremes of their distributional ranges, is ... -

Habitat variability and faunal zonation at the Ægir Ridge, a canyon-like structure in the deep Norwegian Sea
(Peer reviewed; Journal article, 2022)The Ægir Ridge System (ARS) is an ancient extinct spreading axis in the Nordic seas extending from the upper slope east of Iceland (∼550 m depth), as part of its Exclusive Economic Zone (EEZ), to a depth of ∼3,800 m in the ... -

Haddock avoidance reactions during trawling
(ICES CM Documents;1986/B:36, Working paper, 1986)Fish reaction to the whole trawling operation was studied using a stationary echo sounder-system observing the fish in front of the vessel and during trawl passage. Strong avoidance reactions were observed on haddock, ... -
The Haddock in Norwegian Waters - I. Vertebrae Counts and Brood Strength Variations of young fish
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1952)The uniformity in vertebrae number, brood strength and growth which has been shown to exist in young haddock from northern Norway and the Barents Sea implies that these areas are inhabited by one main population. The ... -
The Haddock in Norwegian Waters : Methods in age and growth investigations

The haemoglobin polymorphism in Atlantic cod (Gadus morhua L.); genotypic differences in somatic growth and in maturing age in natural populations. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983
(Flødevigen rapportserie, Conference object, 1984)The two common alleles at the polymorphic haemoglobin locus HbI (Sick, 1961) in the Atlantic cod (Gadus morhua L.) code for proteins whose functional properties are differentially influenced by environmental ... -

Half a century of genetic interaction between farmed and wild Atlantic salmon: Status of knowledge and unanswered questions
(Peer reviewed; Journal article, 2017)Atlantic salmon (Salmo salar) is one of the best researched fishes, and its aquaculture plays a global role in the blue revolution. However, since the 1970s, tens of millions of farmed salmon have escaped into the wild. ... -
Half a century of high-latitude fisheries oceanography research on the "recruitment problem" in Northeast Arctic cod (Gadus morhua)
