Basic Facts Funded through the INCO-DEV section of FP5
Duration of the project: Nov 2001 - Oct 2005
Funded to the sum of almost €1,000,000
6 partner countries (+ 2 subcontractor countries) involved
It is an expansion of AlgaeBase (One of the five largest biological databases in the world) www.algaebase.org
AlgaeBase contains:
34,588 bibliographical references, 2,314 common names, 109,473 distributional records, 17,657 etymological entries, 5,785 genera, 2,879 images, 61,738 species

• Despite its enormous coastline and burgeoning maritime populations, Africa has not seen major developments of a seaweed industry except in Tanzania and South Africa, and recently in Mozambique.
• SeaweedAfrica is prioritizing the entry of information from Africa due to the relative inaccessibility of knowledge of seaweeds form Africa despite the incredible biodiversity which is particularly high on the east coast.
Basic Facts

• In some areas, such as Namibia and the west coast of South Africa, upwelling of cold water shows enormous potential for maricultural development if the right algae and management techniques can be found.
Therefore one of the aims of SeaweedAfrica is
“To increase access to information on seaweeds, allowing
‘‘best practice’best practice’ in sustainable seaweed farming”
Basic Facts
To aid and accelerate seaweed aquaculture through developing the seaweed database to include information on:
• Seaweed uses• Common names• Commercial usage – Aquaculture & Harvesting• Ecological data• Regulation and legislation information
In other words to assemble knowledge currently dispersed particularly information that pertains to the development of an African industry

You can enter a search for:
• Species name such as Gracilaria gracilis
• Common name
• Country
• Ecological / aquaculture or harvest records
An example of a search on the site for the uses associated with Gracilaria gracilis
You will then be given a number of choices to search for further information on this species e.g. uses and compounds highlighted in red above. If you click on this link you will be provided with a list of the seaweed’s uses and their associated compounds.

Potential of SeaweedAfricaResource distribution
Allows any country to identify what species occur on their coast
Uses & potential uses of different species Important for countries who wish to initiate a
seaweed utilisation strategy
Current Resource Yields Scale of harvesting is unappreciated by many Current information on yields will act as a tool
to illustrate the potential sustainable exploitation that can be achieved

Ecological Information Information on life histories of commercial
species is vital Preserving biodiversity May provide a secondary crop
Information on associated species To ensure maximum efficiency of
aquaculture initiatives To facilitate ecological/acceptable
harvesting practices
Methods of cultivation & Harvesting Help to amalgamate different methods to
produce the most appropriate technology
Regulation management First point of contact – country Legislation - country
Who will benefit?• The expanded database aims to satisfy the needs of
policy makers wishing to initiate sustainable seaweed production or effectively regulate already existing seaweed production; whether that production be by harvesting or aquaculture.
• Other groups that will benefit from the information include universities, industry, government agencies, multidisciplinary research institutions, libraries, museums, non-governmental organisations and interested individuals.
