RESEARCH SHIP AFRICANA

 

RESEARCH SHIP AFRICANA

RESEARCH SHIP AFRICANA

BACKGROUND:
Africana, was built and commissioned in 1982 for the then Sea Fisheries Research Institute. She has achieved close to 40 000 scientific stations. The Africana is based in Cape Town and owned by the Department of Agriculture, Forestry and Fisheries.
The Africana is the flagship of the Branch: Fisheries. Her main roll is as a platform for research and monitoring the fish stocks which is undertaken to guide the management of South Africa’s offshore fisheries. An array of scientific winches caters for biological, physical and chemical oceanography research.
A suite of hull mounted acoustic transducers, high tech scientific echo-sounders and her speacialised design makes her one of the best vessel in the world for hydro-acoustic surveys.
A purpose- built stern trawler, the Africana is designed specifically for both Pelagic and Demersal trawling, hydro acoustic surveys, deployment of underwater sensors up to 6000m depth, towing of various sampling nets and is ice strengthened for working in the southern oceans where she has conducted krill surveys in the past.
