    Cruise Report Dr. Fridtjof Nansen - Fisheries Resource Survey Iran, 21-23 May; 30 May-2 June; 12-15 June 1984 1984

    The research vessel “Dr. Fridtjof Nansen” is scheduled to undertake several fishery resources surveys in the North Arabian Sea during 1983-84. These investigations are part of the UNDP/FAO Global Programme GLO/82/001. The first cruise in Iranian waters under this programme was carried out in late September 1983. The survey programme included acoustical survey for the purpose of mapping fish distribution and abundance estimation, trawling for identification of echo recordings, biological sam pling and hydrographical work. The vessel carried out similar surveys in these waters during the North Arabean Sea Programme 1975-1976. These investigations are reported in five cruise reports, and further analysed by Kesteven et al. (1981). The present survey should, according to the original cruise plan, carry out similar investigations on the shelf of Iran, from Ras al Shir to the Pakistanian border in the period 21 May-2 June 1984. After about 2 days work on this survey, break down in the electric generator made it impossible to operate the trawl gears, and 7 days of the original cruise plan were lost repairing the generator in Dubai. In addition, formal restrictions on travel for the Iranian scientists, reduced the vessels operational time severely. As a consequence the original survey programme had to be reduced and was limited to an acoustic coverage of the mesopelagic resources of the Iranian side of the Oman gulf.

    The research vessel “Dr. Fridtjof Nansen” is scheduled to undertake several fishery resources surveys in the North Arabian Sea during 1983-84. These investigations are part of the UNDP/FAO Global Programme GLO/82/001. The first cruise in Pakistani waters under this programme was carried out in September 1983. The survey programme included acoustical survey for the purpose of mapping fish distribution and abundance estimation, trawling for identification of echo recordings, biological sampli ng and hydrographic observations. “Dr. Fridtjof Nansen” carried out similar surveys in Pakistani waters during the North Arabian Sea Programme in 1975-76 and during the Joint NORAD/Pakistan Project from January to June 1971. The results from these investigations have been presented in cruise reports as well as in summary reports. The present survey was carried out during the period 19 January to 2 February 1984. Cruise tracks and the stations worked out appear in Figure 1. The sci entific staff consisted of the following: From Institute of Marine Research, Bergen, Norway:

    In accordance with the survey plan a main acoustical coverage of the shelf from Agadir to Cape Juby was first to be made to localize the aggregations of small pelagic fish, mainly sardines. Then effort was to be concentrated on these aggregations with detailed studies on biomass estimation, target strength and fish behaviour.
