The copepod by the Norwegian name "Raudåte" (Calanus finmarchicus) is an ecologically important species in the Norwegian and Barets Sea. In the food chain it is located between algea and fish, hence the species is a key species regarding energy transfer between primary producers and commericial fish species. Of the coast of Norway it periodically constitutes 90% of standig stock of zooplankton.
Copepodite V with large lipid storage.
The first attempts to culture Calanus finmarchicus is described in Nature (Corkett, 1967), and many following have been unsuccessful. At Sealab in Trondheim, in a collarboration between Biotrix, SINTEF and NTNU, we now have the first multigeneration C. finmarchicus culture in the world.
Studies using the C. finmarchicus culture includes:
Because of the geographic distribution our culture can be used as a model for assessing effects of chemicals on Arctic and Sub-Arctic key species.
During the last six months several projects where the Calanus finmarchicus culture is involved has been funded and launched.
Our research group consists of scientists from different research institutes located at Sealab in Trondheim, Norway. SINTEF Materials and Chemistry, BioTrix, NTNU and SINTEF Fisheries and Aquaculture are the main contributors, but we also have close collaboration with other research institutes both nationally and internationally.
