Each process requires detailed investigation, planning and execution in order to mitigate risk to the aquaculture operation. Failure to deal appropriately with any one of these components of the value chain can doom the entire project.
RAS is a complex, sophisticated engineering and operating process that is capital intensive. However, it is also the only financially viable way to achieve large scale fish production in South Africa. It is also environmentally responsible due to the following:
- Reduced foot print
- Reduced water requirement
- Improved Feed Conversion Ratio
The complexity of developing the RAS project is not dissimilar to the engineering complexity of a large capital project, such as developing a mine. Thus, the work that must be undertaken at the formative stages of project development will often determine whether the project succeeds or fails. It is not a simple process and so securing the input of professional advisors is paramount in ensuring that both capital and time are not needlessly wasted.
Further, success of the operation is often a function understanding the optimal growth cycle of the selected species. This requires knowledge of the species-specific factors of success:
