Biochemical composition of Hediste diversicolor (OF Müller, 1776) (Annelida: Nereidae) reared on different types of aquaculture sludge
Anglade, Inka; Dahl, Thomas; Kristensen, Bjørn; Hagemann, Andreas; Malzahn, Arne; Reitan, Kjell Inge (Peer reviewed; Journal article, 2023)Introduction: Sustainable growth of the salmon aquaculture industry is highly dependent on the availability of new feed resources as well as improved management and utilization of waste streams from production. Polychaetes ... -
Can lipidomics help identifying egg quality in ballan wrasse?
Malzahn, Arne; Sarno, Antonio; Hagemann, Andreas; Farkas, Julia; Musialak, Luciana Alves; Kjørsvik, Elin; Hansen, Bjørn Henrik (Peer reviewed; Journal article, 2022)Ballan wrasse (Labrus bergylta) is in the limelight of aquaculture research due to the species role as cleaner fish in salmon aquaculture. A major drawback is that the salmon industry still depends on wild caught fish as ... -
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 ... -
First feed matters: The first diet of larval fish programmes growth, survival, and metabolism of larval ballan wrasse (Labrus bergylta)
Malzahn, Arne; Ribicic, Deni; Hansen, Bjørn Henrik; Sarno, Antonio; Kjørsvik, Elin; Aase, Anna Sigrid Nordberg; Alves Musialak, Luciana; Garcia Calvo, Laura; Hagemann, Andreas (Peer reviewed; Journal article, 2022)The use of cleaner fish, such as the ballan wrasse (Labrus bergylta), is important for combatting the sea lice problem in salmonid cage farming. Ballan wrasse is the only wrasse species that is cultivated, though only about ... -
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 ... -
Ova lipid profiling and egg quality in wild and captive lumpfish, Cyclopterus lumpus (Linnaeus, 1758)
Hansen, Bjørn Henrik; Kjørsvik, Elin; Malzahn, Arne; Sarno, Antonio; Kulild, Ole Martin; Farkas, Julia; Nordtug, Trond; Rye, Rebecca; Kvæstad, Bjarne; Lein, Ingrid; Hagemann, Andreas (Peer reviewed; Journal article, 2022)Lumpfish (Cyclopterus lumpus) serves an important role as cleaner fish for removing salmon lice in salmon aquaculture. For this use, cultivated lumpfish are preferred over wild-caught fish to avoid overexploitation of ... -
The role of manipulating photoperiod and temperature in oocyte development of the polychaete hediste diversicolor (O.F. Müller, 1976)
Wang, Haiqing; Hagemann, Andreas; Malzahn, Arne; Handå, Aleksander; Uhre, Marianne; Kjørsvik, Elin; Reitan, Kjell Inge (Journal article; Peer reviewed, 2020-12-08)Three different experiments were conducted to examine the oocyte development of the polychaete Hediste diversicolor in response to changing photoperiod and temperature at three different periods of oogenesis. In experiment ... -
