Application of biological filter in recirculating aquaculture system (RAS) for super-intensive whiteleg (Litopenaeus vannamei) shrimp farming in Vinh Long province

Tóm tắt

   The research and development of a biofilter for whiteleg shrimp farming, intended for high-density cultivation, has been conducted in laboratory settings and practical applications. The results in the laboratory illustrate the high potential for application in practice. To guarantee the procedure's feasibility, it was deemed necessary to implement an experimental application of the process in a pond with an area of 500 m². The parameters for the practical model have been determined for the mass balance of total ammonia, solids, dissolved oxygen, biofilter size, and flow time in the water circulation system. Experimental results indicate a high treatment efficiency, with H₂S removal reaching approximately 77% and an increase in dissolved oxygen concentration ranging from 42% to 48%.
