Improving scallop (Pecten maximus and Placopecten magellanicus) spat production by initial larvae size and hydrodynamic cues used in nursery system
(Journal article; Peer reviewed, 2019)There are several factors affecting scallops during the metamorphosis process that could explain the relatively low post-larvae yield observed in hatcheries. Competent bivalve larvae respond to different settlement cues ... -
Improving size selection in the Norwegian red king crab (Paralithodes camtschaticus) fishery through modification to pot design and soak time.
(Peer reviewed; Journal article, 2023)Red king crab (Paralithodes camtschaticus) represent a valuable inshore fisheries resource for communities in northern Norway. The fishery is regulated east of the 26th meridian by vessel quotas and a minimum landing size ... -
In a squeeze: Epibiosis may affect the distribution of kelp forests
(Journal article; Peer reviewed, 2019)The processes limiting the population recovery of the kelp Saccharina latissima after recent large‐scale loss from the south coast of Norway are poorly understood. Previous investigations do, however, suggest that the ... -
In sea trout, the physiological response to salmon louse is stronger in female than in males
(Peer reviewed; Journal article, 2023)The aims of this study were to compare male and female sea trout (Salmo trutta) with respect to their hypo-osmoregulatory ability over a simulated migration to seawater and their clinical and physiological response to ... -
In situ calibration of observatory broadband echosounders
(Peer reviewed; Journal article, 2020)Today, numerous scientific echosounders are used as continuously monitoring systems in ocean observatories. These echosounders are usually calibrated in shallow water, either in laboratory tanks or at random ocean docks ... -
In situ recordings of large gelatinous spheres from NE Atlantic, and the first genetic confirmation of egg mass of Illex coindetii (Vérany, 1839) (Cephalopoda, Mollusca)
(Peer reviewed; Journal article, 2021)In total, 90 gelatinous spheres, averaging one meter in diameter, have been recorded from ~ 1985 to 2019 from the NE Atlantic Ocean, including the Mediterranean Sea, using citizen science. More than 50% had a dark streak ... -
In situ sea lice egg sterilization with UVC light
(Rapport fra havforskningen;2019 - 29, Research report, 2019)Sea-cage salmon farming creates ideal conditions for population growth of the salmon louse Lepeophtheirus salmonis, potentially leading to poor welfare and mortality in farmed salmon and nearby wild salmonids. Frequent ... -
In vitro assessment of protein digestibility and mineral solubility of black soldier fly larvae meals for monogastric animals
(Peer reviewed; Journal article, 2022)Animal farming is a fast-growing sector which demands a large supply of feed materials and the search for novel feed ingredients with a smaller impact on the global environment has been intensified. However, before the ... -
In vitro digestion method to evaluate solubility of dietary zinc, selenium and manganese in salmonid diets
(Peer reviewed; Journal article, 2020)The determination of dietary mineral solubility is one of the main steps in the evaluation of their availability for a given species. -
In vitro toxicity of glyphosate in Atlantic salmon evaluated with a 3D hepatocyte-kidney co-culture model
(Peer reviewed; Journal article, 2022)A novel 3D Atlantic salmon co-culture model was developed using primary hepatocytes and kidney epithelial cells isolated from the same fish. Mono and co-cultures of primary hepatocytes and kidney epithelial cells were ... -
In vivo CRISPR/LbCas12a-mediated knock-in and knock-out in Atlantic salmon (Salmo salar L.)
(Peer reviewed; Journal article, 2023)Genome editing using the CRISPR/Cas system offers the potential to enhance current breeding programs and introduce desirable genetic traits, including disease resistance, in salmon aquaculture. Several nucleases are available ... -
Inclusion of recreational fishing in data-limited stocks: a case study on Norway lobster (Nephrops norvegicus) in Norway
(Others, 2022)Recreational and semi-subsistence fisheries are challenging to monitor but can act as precursors of developments in commercial fisheries, contributing information in data-limited situations. We compared trends in commercial ... -
Incorporating intra-annual variability in fisheries abundance data to better capture population dynamics
(Peer reviewed; Journal article, 2022)To reduce the risk of overexploitation and the ensuing conservation and socio-economic consequences, fisheries management relies on receiving accurate scientific advice from stock assessments. Biomass dynamics models used ... -
Incorporation of feed and fecal waste from salmon aquaculture in great scallops (Pecten Maximus) co-fed by different algal concentrations
(Peer reviewed; Journal article, 2019)Juvenile scallops of Pecten maxiumus were studied to see the capability to clear out and incorporate salmon feed and feces (30 µg L-1). Algae were also given, in a low and high concentration in addition to feed and faeces, ... -
Increased barium levels in recent marine sediments from the Norwegian and Barents Seas suggest impact of hydrocarbon drilling and production
(Peer reviewed; Journal article, 2023)Barium (Ba) in recent marine sediments can originate from natural and anthropogenic sources including discharges from the oil and gas industry. In this study, we use data from the Norwegian and Barents Seas to assess whether ... -
Increased catches of snow crab (Chionoecetes opilio) with luminescent-netting pots at long soak times
(Peer reviewed; Journal article, 2020)Luminescent netting increases the catch rate of snow crabs (Chionoecetes opilio) over short soak times (1 d), however the commercial fishery often requires longer soak periods, up to1 week. Building on previous research, ... -
Increased functional diversity warns of ecological transition in the Arctic
(Peer reviewed; Journal article, 2021)As temperatures rise, motile species start to redistribute to more suitable areas, potentially affecting the persistence of several resident species and altering biodiversity and ecosystem functions. In the Barents Sea, a ... -
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, ... -
