Understanding microbial drivers towards control of biofouling in marine aquaculture

Biofouling is a notorious and costly issue in marine aquaculture. The current best practice relies on mitigation of biofouling after its formation utilizing frequent manual cleaning incurring large operational expenditure and OH&S concerns. This PhD thesis aims to assess the practical feasibility of a novel silane-QAC-dendritic polymer coating that can prevent the formation of biofouling on fish pens and other marine infrastructure. Preliminary results showed that the coating strongly inhibited the growth of bacteria, providing strong evidence for the successful implementation in practice. To evaluate its effectiveness, a comprehensive series of laboratory and field trials will be conducted to assess 1) the anti-biofouling performance 2) the coating stability and service life, and 3) the microbiological safety and efficacy. Based on the experimental results obtained in this PhD thesis, a comprehensive cost-benefit analysis will be conducted.
