Spatial, Ecological and Social Dimensions of Assessments for Bivalve Farming Management
(Chapter, 2019)The general purpose of assessment is to provide decision-makers with the best valuable data, information, and predictions with which management decisions will be supported. Using case studies taken from four scientific ... -
Spatially explicit estimates of stock sizes, structure and biomass of herring and blue whiting, and catch data of bluefin tuna
(Journal article; Peer reviewed, 2015) -
Spatially explicit stock assessment uncovers sequential depletion of northern shrimp stock components in the North Sea
(Others, 2023)Space is a critical component of fisheries management. Despite this, very few of the world's fish and shellfish stocks are currently assessed using methods that are spatially structured. In the Northeast Atlantic, northern ... -
Spatio-temporal dynamics in the dissolved nutrient waste plume from Norwegian salmon cage aquaculture
(Peer reviewed; Journal article, 2018)The aim of this study was to define the waste plume dynamics around a salmon farm in Norway. Systematic water sampling and numerical modeling were implemented to define nutrient concentrations in the upper water column at ... -

(Peer reviewed; Journal article, 2018)The aim of this study was to define the waste plume dynamics around a salmon farm in Norway. Systematic water sampling and numerical modeling were implemented to define nutrient concentrations in the upper water column at ... -
Spatio-temporal turnover and drivers of bentho-demersal community and food web structure in a high-latitude marine ecosystem
(Peer reviewed; Journal article, 2022)Assess the spatial and temporal turnover of bentho-demersal marine fauna by integrating ecological metrics at the community and food web levels and evaluate their main environmental and anthropogenic drivers. -
Spatiotemporal variability of barium in arctic sea-ice and seawater
(Journal article; Peer reviewed, 2018)Freshwater export from the Arctic is critical in determining the density of water at sites of North Atlantic deep water formation, which in turn influences the global flux of oceanic heat and nutrients. We need geochemical ... -
Spatiotemporal variation in climatic conditions across ecosystems
(Peer reviewed; Journal article, 2021)Environmental variation in time and space affects biological processes such as extinction risk and speed of adaptation to environmental change. The spatial structure of environmental variation may vary among ecosystems, ... -

Spawning Atlantic cod (Gadus morhua L.) exposed to noise from seismic airguns do not abandon their spawning site
(Peer reviewed; Journal article, 2022)Seismic airgun surveys may disturb and displace fish at large ranges. If such displacement causes fish to abandon spawning grounds, reproductive success could be impacted. To investigate whether airgun sound causes cod ... -
Spawning energetics and otolith microchemistry provide insights into the stock structure of bonga shad Ethmalosa fimbriata
(Journal article; Peer reviewed, 2019)The gross energy content of spawning batches and the microchemistry of sagittal otoliths in individual female bonga shad Ethmalosa fimbriata were compared between contrasting sampling sites at the Senegalese southern coast ... -
Spawning manipulation, broodfish diet feeding and egg production in farmed Atlantic salmon
(Peer reviewed; Journal article, 2024)Atlantic salmon aquaculture relies on continuous supply of high quality eggs. Broodfish nutrition and manipulation of ovulation time (photoperiod and temperature) are key factors. The optimum feeding period with broodfish ... -
Spawning time in adult polar cod (Boreogadus saida) altered by crude oil exposure, independent of food availability
(Peer reviewed; Journal article, 2023)Fish early life stages are well known for their sensitivity to crude oil exposure. However, the effect of crude oil exposure on adults and their gametes during their spawning period is not well studied. Polar cod, a key ... -
SpawnSeis MV exposure experiment - Survey Report — IMR Survey number 2022812
(Toktrapport;2023 - 4, Research report, 2023)In the project SpawnSeis MV, we aimed to study how a novel seismic source, a marine vibrator, affects behaviour and acoustic communication of wild, free ranging, spawning cod. Cod behaviour was studied by using acoustic ... -
Speciation analysis of organoarsenic species in marine samples: method optimization using fractional factorial design and method validation
(Peer reviewed; Journal article, 2021)Organoarsenic species in marine matrices have been studied for many years but knowledge gaps still exist. Most literature focuses on monitoring of arsenic (As) species using previously published methods based on anion- and ... -
Speciation of zinc in fish feed by size exclusion chromatography coupled to inductively coupled plasma mass spectrometry – using fractional factorial design for method optimisation and mild extraction conditions
(Journal article; Peer reviewed, 2018)Zinc (Zn) is an element essential to all living organisms and it has an important role as a cofactor of several enzymes. In fish, Zn deficiency has been associated with impaired growth, cataracts, skeletal abnormalities ... -
Species composition of three size fractions of zooplankton used in routine monitoring of the Barents Sea ecosystem
(Peer reviewed; Journal article, 2021)Size fractionation with 2000 and 1000 μm screens is used by the Institute of Marine Research in Norway in routine monitoring of zooplankton biomass. This study examines the separation of taxa by this procedure. For copepods ... -
Species separation efficiency and effect of artificial lights with a horizonal grid in the Basque bottom trawl fishery
(Peer reviewed; Journal article, 2022)Achieving effective size selectivity for different species within a fishing gear is a major challenge in mixed fisheries. Fish behaviour may be exploited to separate species into separate codends where different selective ... -
Species-specific discrimination of insect meals for aquafeeds by direct comparison of tandem mass spectra
(Journal article; Peer reviewed, 2019)Insect protein has the potential to become a sustainable feed ingredient for the rapidly growing aquaculture industry. In the European Union, insect derived protein is placed under the same legislation as processed animal ... -
The specification of the data model part in the SAM model matters
(Peer reviewed; Journal article, 2020)This paper considers a general state-space stock assessment modeling framework that integrates a population model for a fish stock and a data model. This way observed data are linked to unobserved quantities in the population ...
