Increasing catch efficiency for Nephrops in deep-water shrimp (Pandalus borealis) trawl fisheries
(Peer reviewed; Journal article, 2022)In Skagerrak and the North Sea, coastal vessels harvest deep-water shrimp (Pandalus borealis) in a mixed fishery, in which catches of Nephrops (Nephrops norvegicus) are of economic importance for the fleet. Fishermen ... -
Increasing depth distribution of Arctic kelp with increasing number of open water days with light
(Peer reviewed; Journal article, 2023)Kelps are a dominant macrophyte group and primary producer in Arctic nearshore waters that provide significant services to the coastal ecosystem. The quantification of these services in the Arctic is constrained, however, ... -
Increasing dietary levels of the omega-3 long-chain polyunsaturated fatty acids, EPA and DHA, improves the growth, welfare, robustness, and fillet quality of Atlantic salmon in sea cages
(Peer reviewed; Journal article, 2022)The present study evaluated the effects of increasing the dietary levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in Atlantic salmon (Salmo salar) reared in sea cages, in terms of growth performance, ... -
Increasing dietary n-6 FA while keeping n-3 FA stable decreases EPA in polar lipids of farmed Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2020)There is an increased use of vegetable oils containing n-6 fatty acids (FA) in aquafeeds, and several trials indicate that there might be an increased requirement of EPA and DHA for Atlantic salmon when they are fed higher ... -
Increasing Dip Net Mesh Size Results in More Fin Splits in Post-Smolt Atlantic Salmon (Salmo salar)
(Peer reviewed; Journal article, 2022)Dip nets are widely used to retrieve fish from the water but can cause injuries to the fish. The objective of this study was to document the potential effects of dip net mesh size with respect to external injuries, more ... -
Increasing Sequence Search Sensitivity with Transitive Alignments
(Journal article; Peer reviewed, 2013-02-14)Sequence alignment is an important bioinformatics tool for identifying homology, but searching against the full set of available sequences is likely to result in many hits to poorly annotated sequences providing very little ... -
Increasing temperature and prey availability affect the growth and swimming kinematics of Atlantic herring (Clupea harengus) larvae
(Peer reviewed; Journal article, 2022)Climate change will increase the magnitude and duration of warming events and the variability in the phenology and abundance of available prey to the early life stages of fish. These factors influence physiological, ... -
Increasing the dietary n-6/n-3 ratio alters the hepatic eicosanoid production after acute stress in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2021)Earlier studies have indicated that a high inclusion of n-6 fatty acids (FA) in feeds for Atlantic salmon can affect the stress response. To test this hypothesis, Atlantic salmon (Salmo salar) were fed diets containing ... -
Increasing the uptake of multispecies models in fisheries management
(Peer reviewed; Journal article, 2023)Multispecies models have existed in a fisheries context since at least the 1970s, but despite much exploration, advancement, and consideration of multispecies models, there remain limited examples of their operational use ... -
Incubation of halibut yolk sac larvae improved by addition of freshwater and oxygen
(ICES CM Documents;1998/L:14, Working paper, 1998)Halibut fry has been produced regularly by scientific and commercial institutions since late 80- ties. The yearly number of halibut fry produced have, however, not fulfllled the optimistic expectations. This could partly ... -
Indel locations are determined by template polarity in highly efficient in vivo CRISPR/Cas9- mediated HDR in Atlantic salmon
(Peer reviewed; Journal article, 2020)Precise gene editing such as CRISPR/Cas9-mediated homology directed repair (HDR) can increase our understanding of gene function and improve traits of importance for aquaculture. This fine-tuned technology has not been ... -
Indication of high natural mortality for juvenile herring from acoustic and tagging data.
(ICES CM Documents;1980/H:62, Working paper, 1980)Natural mortality for juvenile herring (Norwegian Spring spawners) is discussed on the basis of following data: 1. Acoustic estimates of the 1975 and 1976 yearclasses of herring as 0-group and estimates from tagging ... -
Indirect climatic forcing of the Barents Sea capelin: a cohort effect
(Journal article; Peer reviewed, 2004-06-08)Planktivorous capelin is a key species in the Barents Sea, being of great importance in the exploitation of plankton production in this subarctic region. However, in years with a successful reproduction of the Norwegian ... -
Individual and population-level responses to ocean acidification
(Journal article; Peer reviewed, 2016-01-29)Ocean acidification is predicted to have detrimental effects on many marine organisms and ecological processes. Despite growing evidence for direct impacts on specific species, few studies have simultaneously considered ... -
Individual based spatial models with evolved fish behaviour
(ICES CM Documents;1998/J:16, Working paper, 1998)Due to spatial heterogeneity, the survival and growth of fishes depend upon their habitat. For mobile pelagic fishes, it hence becomes important to analyse the factors responsible for spatial dynamics in order to understand ... -
Individual fish tank arrays in studies of Lepeophtheirus salmonis and lice loss variability
(Journal article; Peer reviewed, 2011-11-03)In studies of the salmon louse Lepeophtheirus salmonis (Krøyer, 1837), experimental design is complicated by a highly variable and unpredictable lice loss among common experimental tanks and a substantial rate of host ... -
Individual growth rate and age at first sexual maturity in Atlantic salmon
(Fiskeridirektoratets skrifter, Serie Havundersøkelser, Research report, 1978)Growth rates and possible connection between growth rate and age at maturation were studied on individually tagged salmon originating from different river populations. Great variations in growth rate and in age at first ... -
