摘要： Integrated multi-tropic aquaculture (IMTA) systems have been used in China for many years and have achieved significant economic, social, and ecological benefits. However, there is still a lack of benthic bioremediation species that can effectively utilize the aquaculture particulate organic waste in the system. PolychaetePerinereis aibuhitensisGrube is used as an environmental remediation species for large-scale aquaculture to reduce particulate organic waste, which is of great significance to environmental protection. To improve bio-elements utilization efficiency,P. aibuhitensiswas applied for IMTA indoor fish (Hexagrammos otakii) farming. Results showed that in the system, production of 1 kg of the fish discharged 2 141-2 338 mg of carbon and 529-532 mg of nitrogen, while in the monoculture of the fish, the figures were 3 033-3 390 mg and 764-794 mg, or 24.84%-35.26% and 30.35%-33.32% less, respectively. This approach promoted IMTA technology that could utilize the particulate organic waste from intensive aquaculture and reduce the adverse environmental effects.
