Abstract:

Xiuzhou District is a strong traditional fishery area in Zhejiang Province. In 2023, the total output of aquatic products in Xiuzhou is 33 411 t, and the aquaculture area is 5 547.39 hm². Xiuzhou vigorously promotes the recirculating aquaculture model, which has two main types:1. The use of infrastructure construction to aquaculture water pond circulating water fish, that is, “runway” fish culture; 2.Circular farming in the subsurface flow wetland of paddy fields. At the same time, we explored and implemented a long-term operation and maintenance mechanism of aquaculture tail water, forming a circulating aquaculture model with Xiuzhou characteristics. Through the establishment of a multi-level linkage organization system, the introduction of support policies, tracking the whole process of aquaculture production, and the whole-chain curing technology model, while vigorously demonstrating and promoting the model and achieved remarkable results.

Key words: circulating water, aquaculture, circulating aquaculture model
