A local polytechnic has developed a farming system that can potentially benefit fish farmers. The common problems cited by fish farmers include a lack of technical know-how, high fish mortality rates and no control over water quality. Over the past year, researchers and students from the Singapore Polytechnic have developed a commercial system that allows high-density fish farming by having 36,000 fish in 120 bulk containers. This allows for further productivity in a limited land space. The individual bulk containers also have an auto-feeding system. The system also makes use of existing technologies for water treatment to take place naturally. Channel News Asia 11 Dec 2011
