Pan J.F., 2026, Water quality regulation for sustainable production of giant freshwater prawn (Macrobrachium rosenbergii), Bioscience Evidence, 16(4): 264-276 (doi: 10.5376/be.2026.16.0020)

Giant freshwater prawn (Macrobrachium rosenbergii) is an important freshwater aquaculture species worldwide. However, with the increase in farming density and intensification, problems such as water eutrophication, dissolved oxygen fluctuations, ammonia nitrogen accumulation, and algae imbalance have gradually become major factors limiting the sustainable development of the industry. This study summarizes the effects of temperature, dissolved oxygen, pH, nitrogen compounds, water transparency, and algal dynamics on the growth, survival, and health of M. rosenbergii. It also analyzes the application effects of water environment management strategies, including aeration management, biofloc technology, probiotic regulation, precise feeding, and integrated multi-trophic aquaculture. Based on practical cases of pond culture, biofloc farming, ecological polyculture, and rice–prawn integrated farming in Zhejiang Province, China, this study discusses the positive effects of water quality improvement on growth performance, immune health, feed utilization efficiency, and economic benefits. Optimization of a single water quality indicator is difficult to meet the requirements of high-density aquaculture. A comprehensive management model combining microbial regulation, ecological circulation, and digital monitoring can effectively improve pond environmental stability, reduce farming risks, and achieve coordinated improvement of production and ecological benefits. In the future, precise water quality regulation systems based on the Internet of Things, artificial intelligence, and climate-adaptive management will become an important direction for promoting the green, efficient, and sustainable development of the M. rosenbergii industry.
