«Dr. Fridtjof Nansen» The fishery research vessel «Dr. Fridtjof Nansen" belongs to the Norwegian Agency for Development Cooperation (NORAD). It was designed and built for scientific and exploratory investigations of fishery resources of developing countries, under a joint plan with the Fisheries Department of FAO. A list of the vessels operational assignment from 1975 to 1987 is shown on the back cover. The Institute of Marine Research. Bergen is under a subcontract with NORAD responsible for the operation of the vessel, and the various research programmes were planned and conducted jointly with FAO and the relevant fisheries research organizations in the countries concerned. Results of the previous surveys have been presented in a
number of cruise-and progress reports under each programme. |
