Abstract
M.Sc.
This project considers the feasibility of using heated cooling water from coal-fired
power stations within Eskom for the culturing of C/arias gariepinus (Sharptooth
catfish) and Oreochromis mossambicus (Mozambique tilapia). The work includes: an
overview of world wide trends in power plant thermal effluent aquaculture, the
identification of suitable power stations for aquaculture, long term monitoring of the
physical and chemical characteristics of the cooling water at selected power stations,
including the effects of the cooling water on the growth response, food conversion,
condition factor, survival rate and suitability for human consumption of the
aforementioned fish species reared in the cooling water at Matla and Kriel Power
Stations.
