Overvåking av blåskjellbestanden – grunnundersøkelse 2021 og 2022
Strohmeier, Tore; Strand, Øivind; Gatti, Paul; Aguera, Antonio (Rapport fra havforskningen;2022 - 38, Research report, 2022)Blåskjell (Mytilus sp.) er utbredt langs hele kysten av Norge. I de siste 15 årene har Havforskningsinstituttet (HI) mottatt meldinger om at blåskjell er blitt borte fra steder hvor det vanligvis sankes skjell. HI utviklet ... -
Phytoplankton depletion by mussel aquaculture: high resolution mapping, ecosystem modeling and potential indicators of ecological carrying capacity
Cranford, Peter J.; Li, William; Strand, Øivind; Strohmeier, Tore (ICES CM documents;2008/ H:12, Working paper, 2008)Mussels held in suspended culture have an exceptional capacity to filter the water column and reduce suspended particle concentrations. However, seston depletion is only of concern if the phytoplankton are cleared faster ... -
Potential methodological influences on the determination of particle retention efficiency by suspension feeders: Mytilus edulis and ciona intestinalis
Cranford, Peter J.; Strohmeier, Tore; Filgueira, Ramón; Strand, Øivind (Journal article; Peer reviewed, 2016)The retention efficiency (RE) of suspension-feeding bivalve molluscs depends on particle size and is generally assumed to decline below a maximum retention of particles larger than 3 to 7 µm. Previous suggestions that the ... -
Primary production enhancement by artificial upwelling in a western Norwegian fjord
Aure, Jan; Strand, Øivind; Erga, Svein Rune; Strohmeier, Tore (Journal article; Peer reviewed, 2007-12-20)To enhance primary production rate for shellfish cultivation in fjords, a large-scale artificial upwelling experiment was carried out in a western Norwegian fjord during the summers of 2004 and 2005. Pumping 2 m3 s–1 ... -
Regulating Services of Bivalve Molluscs in the Context of the Carbon Cycle and Implications for Ecosystem Valuation
Filgueira, Ramón; Strohmeier, Tore; Strand, Øivind (Chapter, 2019)The role of marine bivalves in the CO2 cycle has been commonly evaluated as the balance between respiration, shell calcium carbonate sequestration, and CO2 release during biogenic calcification; however, this individual-based ... -
Restoration of carrying capacity of mussel farming in fjords by use of artificial upwelling
Aure, Jan; Strand, Øivind; Erga, Svein Rune; Strohmeier, Tore (Conference object, 2007-06-11) -
Seasonal variability in nutrient regeneration by mussel Mytilus edulis rope culture in oligotrophic systems
Jansen, Henrice M.; Strand, Øivind; Strohmeier, Tore; Krogness, Cathinka; Verdegem, Marc; Smaal, Aad (Journal article; Peer reviewed, 2011-06-09)Blue mussel Mytilus edulis cultures contribute to nutrient cycling in coastal ecosystems. Mussel populations filter particulate nutrients from the water column and inorganic nutrients are regenerated by excretion of metabolic ... -
Seasonal variations in mercury, cadmium, lead and arsenic species in Norwegian blue mussels (Mytilus edulis L.) – Assessing the influence of biological and environmental factors
Gomez Delgado, Ana Isabel; Tibon, Jojo; Silva, Marta Sofia; Lundebye, Anne-Katrine; Aguera, Antonio; Rasinger, Josef; Strohmeier, Tore; Sele, Veronika (Peer reviewed; Journal article, 2023)Blue mussels (Mytilus edulis L.) can accumulate undesirable substances, including the potentially toxic elements (PTEs) cadmium (Cd), mercury, (Hg), lead (Pb), arsenic (As) and As species. In this study, the levels of PTEs ... -
Spatial and temporal organic carbon burial along a fjord to coast transect: A case study from Western Norway
Duffield, Christopher James; Alve, Elisabeth; Andersen, Nils; Andersen, Thorbjørn J.; Hess, Silvia; Strohmeier, Tore (Journal article; Peer reviewed, 2017)We investigated spatial and temporal changes in accumulation rate and source of organic carbon on a gradient along the Lysefjord and the more coastal Høgsfjord, Western Norway. This was achieved through analysis of total ... -
Spatio-temporal dynamics in the dissolved nutrient waste plume from Norwegian salmon cage aquaculture
Jansen, Henrice M; Broch, Ole Jacob; Bannister, Raymond; Cranford, Peter J.; Handå, Aleksander; Husa, Vivian; Jiang, Zengjie; Strohmeier, Tore; Strand, Øivind (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 ... -

Strømforhold, fødetilgang og algetoksiner i et blåskjellanlegg
Aure, Jan; Strohmeier, Tore; Duinker, Arne; Castberg, Tonje; Svardal, Asbjørn Martin (Fisken og havet, Research report, 2002)Seawater currents, mussel (Mytilus edulis L.) condition index (content of soft tissue), algae concentrations and algae toxins (DST) were measured in a commercial farm in Lysefjorden, in southern Norway. Based on the data ... -
Temporal and spatial variation in food availability and meat ratio in a longline mussel farm (Mytilus edulis)
Strohmeier, Tore; Duinker, Arne; Strand, Øivind; Aure, Jan (Journal article; Peer reviewed, 2008-02-11)The influence of temporal and spatial variation in food availability on mussel meat ratio and biomass was studied in a longline mussel farm (100 m wide and 250 m long, Mytilus edulis) during an eight-month period. Current ... -
