Abstract:
In order to find the key stage causing serious environmental pollution in aquaculture industry production, relevant input and output data of the
Penaeus vannamei industry in Rizhao City was collected by field research. The eFootprint software was used to evaluate the life cycle assessment of the environmental impacts of the two culture modes (industrial aquaculture and pond culture). The results show that the environmental impact of the industrial aquaculture were greater than that of pond culture. Among the environmental impacts, the most influential factors were water resource consumption index, the eutrophication potential value index, the climate change environmental impact index, the acidification environmental impact index and the primary energy consumption environmental impact index. Environmental impact index of water resource consumption in industrial aquaculture and in pond culture were 17.72 and 4.73, the eutrophication potential value impact index 6.12 and 2.24, the climate change environmental impact index 3.46 and 0.91, the acidification environmental impact index 2.63 and 0.77, the primary energy consumption environmental impact index 0.69 and 0.17, respectively. Therefore, strengthening environmental management in the upstream industry of aquaculture, trading-off the production planning of pond culture and industrial aquaculture, improving the effective use of water resources are the key measures to promote healthy development of aquaculture.
