A number of indigenous Southern African fish species would be ideal for aquaculture operations. It’s time for serious research into their potential.
Private fish farms and government are working together to breed tilapia and grow aquaculture production in Zambia.
While the Nile tilapia is the fastest grower, it is easier to obtain a permit for the slower-growing Mozambique tilapia.
The production of trout remains a heated topic between conservationists and aquaculturists.
Many experts have the theoretical knowledge, but fail to put themselves in the shoes of the rural, small-scale fish farmer.
Green water culture provides a highly nutritious ‘soup’ of feed for fish stock, promoting faster growth. It also cuts out the high cost of artificial feed.

If you want to grow plants and decent-sized fish, the first step is to get rid of those plastic circular bins.
There are massive dams and reservoirs in South Africa that are ideal for cage culture, yet are not used for this purpose. What a waste of this marvellous resource!
Brackish water can be put to good use in the cultivation of tilapia. Despite being primarily a freshwater species, tilapia are salt-tolerant and actually thrive in saline conditions.
On paper, many aquaculture systems look appealing, but are they suited to South Africa’s challenging conditions?
