The migration of norwegian herring to icelandic waters and the environmental conditions in may-june, 1961-1964
The present material on zooplankton, temperature and herring have been collected in the Norwegian Sea, from the Faroes along the east and north-east coast of Iceland to Jan Mayen as a part of the Norwegian herring investigations, in collaboration with Iceland and U.S.S.R. during May and June 1961-19...
