Anchovy and Pilchard Spawning Stock Survey on the Africana Voyage 057, November 1987

The main objective of the cruise was to determine acoustically the biomass of the pilchard and anchovy spawning stocks between Hondeklip Bay and the eastern end of the Agulhas Bank. Additionally, the relationship between the distribution of pelagic fish, their eggs and the water temperature was investigated, and chemical samples were taken along lines of stations as part of an ongoing investigation with the supply of nutrients to the Agulhas Bank.

Microplankton monitoring along the west coast of South Africa

Microplankton, comprising of both phyto- and zooplankton in the 20-200μm size range, are a diverse and ecologically important group. They form the foundation of the food web, are instrumental in carbon and nutrient cycling, generate at least 50% of global oxygen and facilitate energy flow to higher trophic levels. Although they are found in all oceans globally, their diversity and abundance is varied. Due to their high sensitivity and rapid response to changes in the environment, their...
