Q: Can I grow tilapia on the Highveld?
A: In summer all parts of South Africa are suitable for growing tilapia if the water is over 20˚C. However, winter water temperatures that fall below 13˚C will kill farmed tilapia, and they will not grow well at temperatures below 18˚C. Thus, only a summer ‘crop’ can be harvested on the Highveld. The use of hot-house tunnels make tilapia farming more geographically widespread, however.
