As pressure grows on the world’s arable land, aquaculture must play a bigger role in food production if we are to feed a population of 9,8 billion by 2050, as estimated by the United Nations, says University of Cape Town (UCT) emeritus professor John Bolton. Bolton is a leading expert on the biology and phylogeography of seaweeds, South African kelp forests, and integrated seaweed–marine animal aquaculture.

Nutritionally, seaweeds as a food are said to contain ‘everything except calories’. He added that the market for seaweeds as ‘functional foods’, offering more than just standard nutrition, is rapidly expanding in Western countries. Bolton has published extensively, not only on the seaweeds of South Africa but also of Namibia, Angola, Madagascar, the Éparses Islands of the Mozambique Channel, Kenya, Mauritius and Reunion.

This has been proven over many years on South African abalone farms which grow the sea lettuce Ulva in abalone effluent, to produce feed for the abalone.” Click here to read the full article. – Bizcommunity
