Penaeus indicus H. Milne Edwards, 1837: resumo das conclusões dos cruzeiros de pesca exploratória entre 1979 e 1983 no banco de Sofala em Moçambique

From 1979 to 1983, several surveys were carried out with research and fishing vessels at Sofala Bank in Mozambique. Their main objective was the assessment of shallow water prawn stocks, as this resource is of great economic importance for the country. A summary of the conclusions of these surveys regarding the species Penaeus indicus is presented. During the rainy season the species occurs closer to the shore than during the dry season. Estimates of biomass are very variable. The spawning peak seems to occur at the beginning of the rainy season (September-October). The spawning areas are located very close to the shore in the northern part of Sofala Bank and South of 17 degree 10'S in the 15-25 m depth interval.

Statistiques de pêche des sardiniers ivoiriens - année 1983

The sardinella fleet landed the same quantity of sardines in 1983 (11200 tons) as in 1982. Sardinella aurita catches would be more important if the "Syndicat des Armateurs" did not impose quotas - in July 300 boxes and in August 100 boxes by fleet by trip. The extension of the effort to herring stock increased the catches of this species and an over estimation of 44% of the effort have been observed in 1983.
