Abstract：Northern coastal regions face significant challenges in aquaculture due to large seasonal temperature variations and short farming cycles，resulting in low resource utilization efficiency and frequent disease outbreaks under traditional monoculture systems. This study systematically optimizes polyculture techniques by leveraging the ecological niche complementarity of kuruma shrimp （Penaeus japonicus），Pacific white shrimp （Litopenaeus vannamei），and swimming crab （Portunus trituberculatus）.Key integrated measures include：Pond infrastructure modification;Interspecies ratio optimization;Precision water quality management.Field trials conducted from January to December 2024 demonstrated that this model achieves an average comprehensive benefit exceeding 30 OOo CNY per unit， providing a viable solution for marine pond aquaculture in northern China.
