To maintain a steady supply of live fish, mariculture is an important fisheries industry in Hong Kong and China. However, threats like toxic algal blooms always cause significant economical loss, and discouraging the development and investment to the industry. Therefore, a rapid detection platform that can offer identification and monitoring of the toxic algae in the aquaculture environment is proposed to be established to provide early warning signals in helping the industry. A detection platform is developed through collaboration between Hong Kong (SKLMP) and partner in Shenzhen (Graduate School at Shenzhen, Tsinghua University). In Hong Kong side, a DNA-based database will be generated for various marine toxic algal species and strands. This DNA information will be used to cross validate the physical parameters obtained by polarization measurement from Shenzhen’s partner. The consented species – and strand- specific physical parameters for each single species can be further linked up and setup in the polarization measuring system. The detection system can be further developed into product for field monitoring application. Any update for the system can be simply made through enriching the database information. We anticipated that this detection platform is highly cost-effective and sustainable in its application.
