The vessel arrived in Luanda on 28 January at 2200 hrs. The scientific staff embarked on 29 January and the vessel departed at 1800 hrs.
Figures 1-4 show the cruise track with the hydrographical sections and the fishing stations. The two first days were spent steaming south mostly along the shelf testing the fishing gears in a few hauls and adjusting the instruments.
Four days were spent working in the Baia dos Tigres area between Porto Alexandre and the border with Namibia. Rich fish concentrations were found in this area with horse mackerel mixed with hake and other demersal fish dominating in the offshore parts of the bank and sardinellas and sardine inshore. A calibration of the acoustic instruments was undertaken inside the Baia dos Tigres.
The shelf between Porto Alexandre and Benguela is mostly narrow and this part was covered in about 1½ day.
From Benguela to Cabeca da Baleia most of the work was concentrated on the inshore parts of the shelf as the offshore parts were largely free of any fish recordings.
Further north, past Pta do Quicombo and Pta do Morro it was found convenient to cover the offshore wide bank areas during the day and spend the night over the inshore parts where the small pelagic fish found here can be sampled with pelagic trawl in the absence of daylight.
The vessel called on Luanda 15-17 Feb. for meetings and change of cruise leader.
The shelf north of Luanda was covered in the period 17-26 Feb. In this area the concentrations of small pelagic fish were considerably lower than in the southern part. The area was surveyed in a grid pattern with semi-random bottom-trawl stations for swept-area analysis.
In the northern part the vessel was forced to anchor several times after nightfall due to heavy oil-drilling activities and poorly updated sea-charts.
The vessel called on Cabinda on 26 Feb. to disembark the Angolan scientists.
During the survey there were carried out:
60 bottom trawl stationsThe total distance surveyed in Angolan waters was 4400 nm.
56 pelagic trawl stations
