Their culture in modern times follows a similar trend to that of tilapias: first domestication trials by the year 1950 and adoption of the North African catfish Clarias gariepinus as the most desirable catfish for aquaculture in the mid 1970s. The growth performance of a number of wild populations of the African catfish C. gariepinus (Clariidae) was assessed by means of the growth index Ø. The values of Ø ranged from 2.97 to 3.67 with some of the highest values coming from the coldest lakes, suggesting that this catfish can grow well at relatively low temperatures, unlike many other tropical species. In the developing world, more than one billion poor people obtain most of their animal protein from fish and 250 million depend on fishing and aquaculture for their livelihoods. This forecast would change in the event of a deteriorating global economy. Aquaculture Research 31: 565 – 573.
