Porphyra spp. Is one of the farmed seaweeds with the highest global output value and has an important impact on the coastal fishery economy and ecological environment. This study reviews the current industrial status of major porphyra producing countries, analyzes the economic value and industrial chain of porphyra cultivation, and explores the ecological and environmental impacts of cultivation activities. The results show that while the porphyra industry generates economic benefits, it can improve Marine water quality and increase carbon sequestration and carbon sinks. However, it also poses risks such as eutrophication and disease transmission. This study introduces the progress of sustainable aquaculture technologies such as eco-friendly breeding models, digital monitoring, and germplasm improvement, and discusses the promoting effects of government policies, fishermen's cooperation, and social awareness on the development of the industry. Take Fujian Province as an example to analyze the experience of sustainable development of the porphyra industry. Finally, we look forward to the future prospects and challenges of the porphyra industry under the influence of climate change and market fluctuations, and put forward comprehensive management suggestions. The results of this study provide a theoretical reference for promoting the sustainable development of the porphyra industry.
