From 27 February to 14 April the R. V. "Johan Hjort" carried out a survey to locate sprawning grounds of capelin. The greatest quantities of eggs were found on gravel and on shell gravel at depths between 25 m and 100 m, but eggs in mall numbers occured down to about 300 m. At the spawning grounds the temperature varied between 3°C and 4°C. Eiders and haddock were observed feeding on capelin eggs.
