The main aim of the study is to assess the productivity and supply chain of aquaculture projects in Gauteng Province, South Africa. The research adopted the use of quantitative method; and collected data and information from the five regions that make up the province. Both primary and secondary data were collected. The study used correlation analyses to determine the perfect fit or negative fit of some variables to supply chain as well as the consumers‟ reactions to the questionnaires. Gross margin analysis as well as gross profit margin ratio was used to determine the profitability of aquaculture production in the province. Findings of the study revealed underutilization of production capacities of the established fish farms. The fish farmers in the study are currently using 36% of the capacities of the established aquaculture projects in the study area. The profit margin was in excess of 40% in all the projects surveyed. The study further revealed lack of proper, effective and efficient supply chain for aquaculture projects which adversely affect aquaculture growth and sustainability in Gauteng Province / Agriculture, Animal Health and Human Ecology / M.
