Dietary and seasonal variability in trophic relations at the base of the North Sea pelagic food web revealed by stable isotope and fatty acid analysis
Katherina L., Schoo; Maarten, Boersma; Malzahn, Arne; Martin G.J., Loeder; Karen H., Wiltshire; Aberle-Malzahn, Nicole (Journal article; Peer reviewed, 2018-11)A two-dimensional biomarker approach including fatty acids and stable isotopes of seston and copepods was applied to examine how the variability at the base of the food web affects trophic interactions between primary ... -

Food-limited growth of larval Atlantic herring Clupea harengus recurrently observed in a coastal nursery area
Paulsen, Matthias; Clemmesen, Catriona; Hammer, Cornelius; Polte, Patrick; Malzahn, Arne (Journal article; Peer reviewed, 2017)Food-limited growth of larval fish, defined as growth rates lower than observed in other habitats or from laboratory experiments at a given temperature, is rarely reported in field studies. This would imply that either ... -
Growth and nutritional composition of the polychaete Hediste diversicolor (OF Müller, 1776) cultivated on waste from land-based salmon smolt aquaculture
Wang, Haiqing; Seekamp, Inka; Malzahn, Arne; Hagemann, Andreas; Carvajal, Ana Karina; Slizyte, Rasa; Standal, Inger Beate; Handå, Aleksander; Reitan, Kjell Inge (Journal article; Peer reviewed, 2019-03-15)Increased aquaculture production will result in increased amounts of waste produced, and these wastes are highly underexploited. Polychaetes might effectively consume such waste and transfer them into compounds as marine ... -
Ocean acidification effects on mesozooplankton community development: Results from a long-term mesocosm experiment
Alguero-Muñiz, Maria; Alvarez-Fernandez, Santiago; Thor, Peter; Bach, Lennart T; Esposito, Mario; Horn, Henriette G.; Ecker, Ursula; Langer, Julia A F; Taucher, Jan; Malzahn, Arne; Riebesell, Ulf; Boersma, Maarten (Journal article; Peer reviewed, 2017-04-14)Ocean acidification may affect zooplankton directly by decreasing in pH, as well as indirectly via trophic pathways, where changes in carbon availability or pH effects on primary producers may cascade up the food web thereby ... -
The Potential for Upscaling Kelp(Saccharina latissima) Cultivation in Salmon-Driven Integrated Multi-Trophic Aquaculture (IMTA)
Fossberg, Julia; Forbord, Silje; Broch, Ole Jacob; Malzahn, Arne; Jansen, Henrice M; Handå, Aleksander; Førde, Henny; Bergvik, Maria; Fleddum, Anne Lise; Skjermo, Jorunn; Olsen, Yngvar (Journal article; Peer reviewed, 2018-11-09)Integrated multi-trophic aquaculture (IMTA) has the potential of reducing open-cage fish farming impacts on the environment while also introducing new value chains. The aim of this study was to investigate the growth and ...
