Abstract
The future of abalone farming in Soulh Africa may provide benefits by the integration of abalone-seaweed re-circulation systems. This is a new system design of abalone fed on a kelp diet integrating seaweed culture facilitated by a re-circulation system. This kind of culture has the potential to increase abalone growth through increased water temperature, minimizing pumping costs while also incorporating production of on-farm seaweed resources. This has, however, the potential disadvantage to increase the suspended particulale concentration in the tank environment, with subsequent negative effects on abalone health. This study ties in with an existing Swedish-South African joint project. The results of this study will be used as inputs when trying to model a complete commercial recirculated abalone farm. Divided into two experiments this study records suspended particulate matter, particle size range and water nutrient concentrations (phosphate, ammonium and nitrite).
