Filgueira, Ramón; Strople, Leah; Strohmeier, Tore; Rastrick, Samuel; Strand, Øivind (Journal article; Peer reviewed, 2019)The growing demand for aquaculture products can only be maintained by increasing the production of lower trophic species such as bivalves and tunicates. Low trophic species avoid the energy losses during trophic transfers ... -

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 ... -
The Potential of Kelp Saccharina japonica in Shielding Pacific Oyster Crassostrea gigas From Elevated Seawater pCO<inf>2</inf> Stress
Jiang, Zengjie; Jiang, Weiwei; Rastrick, Samuel; Wang, Xiaoqin; Fang, Jinghui; Du, Meirong; Gao, Yaping; Mao, Yuze; Strand, Øivind; Fang, Jianguang (Peer reviewed; Journal article, 2022)Ocean acidification (OA) caused by elevated atmospheric CO2 concentration is predicted to have negative impacts on marine bivalves in aquaculture. However, to date, most of our knowledge is derived from short-term ... -
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 ... -
Prøvedyrking av stort kamskjell i mellomkultur - 1995-1996
Brynjelsen, Eirik; Strand, Øivind (Fisken og havet, Research report, 1996)The production of King scallop (Pecten maximus) in culture may involve three steps; artificial spat production in hatchery, intermediate culture for production of seed and production of cornrnercial sized scallops in ... -
Rapid water temperature variations at the northern shelf of the Yellow Sea
Asplin, Lars; Lin, Fan; Budgell, Paul; Strand, Øivind (Peer reviewed; Journal article, 2021)During summer, there is great spatial variability in bottom water temperature on the northern shelf of the Yellow Sea. This variability is associated with a thermal front along the shelf. Oscillatory currents from semidiurnal ... -
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.
