Thanks to an agreement between the Institute of Fisheries Research of Mozambique and the Soviet part Azcherniro and Ingribpomrazvedka, surveys in the waters of Mozambique were conducted from June to August 1981 on the ship Pantikapei. The survey made along the Sofala Bank and Boa Paz (16°00-21°00'S) was at a depths of 11 and 90 meters. Demersal and pelagic fisheries experiments were conducted using acoustic devices. This paper described the results obtained on demersal fishery resources.

Relatório do cruzeiro realizado no Banco de Sofala pelo navio SRTM "Sebastopolsky ribak" de Setembro a Outubro de 1982: camarāo de águas pouco profundas

In September-October 1982, the Soviet ship "Sebastopolsky Rybak" conducted a cruise on the Sofala Bank in the area between 16°20'S and parallel 19°40'S. Two surveys were made, one from South to North (depth 10-110 meters) and vice versa. The type of coverage used was systematic. The Sofala Bank was divided into seven sub-areas. During this cruise sub-areas 3 and 4 were covered. Sub-area 5 has not been fully covered.

From November 18th to December 17th 1982, the SRTM "Sebastopolsky Rybak" carried out research cruises on the Sofala Bank in the area between 16°20'S and parallel 19°40'S. The authors analyze data collected on biological characteristics, sexual maturity and localization of Penaeus indicus, Metapenaeus monoceros, Penaeus japonicus, Penaeus monodon and Penaeus latisulcatus.
