«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 based on a funding of operation to be shared by FAO and Norway.

The first six years of operation have included surveys of the pelagic fish resources of the NW Arabian Sea (1975-76), and of the coastal fish resources of Pakistan, Mozambique, Sri Lanka and Bangladesh (1977-79), and finally those of Burma described in this report. 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 the relevant fisheries research organizations in the countries concerned.

Results of the previous surveys have been reported on in a number of cruise-and progress reports under each programme.
