Researcher Liu Xingguo, invited by Professor Li Dapeng of HZAU, gave a lecture to nearly a hundred attendees themed “Eco-engineering: An Effective Way for Green and Clean Pond Culture” in Conference Hall 109 of Fishery Building on the morning of 14th September.
Liu said, despite its great importance, pond culture is confronted with such problems as extensive production mode, low water and soil utilization rate, severe pollution (pollutants include heavy metal, antibiotic and degradation-resistant compound) and shortage of technical support for transformation and upgrading. He stressed that eco-engineering is a pragmatic approach to realizing “green, clean and targeted” pond culture, a point of view supported by the subsequent display of advanced foreign breeding systems, namely, farming-fishing complex planting and breeding system, inner circulating pond aqua-cultural system and bio-flocculation aqua-cultural system.
Based on his own study, Liu then introduced the research and application of eco-engineering into pond culture in China. In order to solve the problem that current pond culture primarily relies on personal experience while there is an acute shortage of human resources, Liu said his research team had developed a precision aqua-cultural management system through combining big data gathering and information engineering system. The precision system allows farmers to collect data and monitor pond culture under remote, smart and effective management. Nowadays, the green breeding bases, which are more reasonable in biological structure and composition, more effective in water-saving and waste reduction and more profitable in eco-breeding, have been widely applied in China, including circulating pond cultural base, water-head eco-breeding base, comprehensive planting-breeding base and eco-fallow base.
At last, Liu showed us the grading pond cultural system of megalobrama amblycephala, the south-north relay breeding system of tilapia mossambica and the highly-efficient green pond cultural system and suggested that we should divert our attention from the traditional notion of pond culture to green and clean production system and precision management in aquaculture as “green, clean and targeted” pond culture will be the trend in the coming years.
The forum concluded with a question & answer session.
