Abstract:

As an advantaged group of demersal polychaete animals, Nereis diversicolor is widely used in ecological remediation. Shrimp pond has long-term cultivation in high density, and the problems such as substrate aging and deterioration of water quality exist, leading to the popularity of shrimp disease and creating massive loss. The overall quality of sedimentary environments clearly determines the outcomes of shrimp cultivation. Putting a certain density of Nereis diversicolor (N. diversicolor) in the shrimp pond can effectively relieve accumulation in the harmful materials. With the increased utilization of the internet of things (IoT) in aquiculture, aquacultural informatization will become a trend in the future. Beginning with a discussion on the ecological remediation function of N. diversicolor, the authors denotes the importance and necessity of mixed culture of shrimp and N. diversicolor. They designed the shrimp-N. diversicolor co-cultivation informatization breeding mode, while combining the concepts of informatization and ecologicalization with intensification. Compared with the existing traditional intensive farming, the new pattern introduces N. diversicolor to the shrimp pond, allowing it to purify itself. It utilizes the IoT technology, so as to effectively realize the integration of aquiculture and artificial intelligence. Moreover, it enhances the breeding level and quality of the aquatic products. However, the shrimp-N. diversicolor co-cultivation informatization breeding mode is now at a stage of exploration and establishment; thus, there are numerous problems and difficulties that need to be resolved and overcome in the actual production process. This paper analyzes possible difficulties that may emerge with the mode, and peers into the future of its application.
