This invention discloses a land-based circular pond ecological seedling cultivation system and method for giant freshwater prawns, belonging to the field of seedling cultivation technology. It includes steps such as stocking, water quality management, feeding management, pond transfer, and larval desalination. The system maintains a microalgae abundance of 10⁴-10⁷ cells / mL through microecological regulation, adds beneficial microecological agents, and purifies the water using a microfiltration machine, disinfection tank, and water purification tank. Feeding management is adjusted according to the larval growth stages: no feeding in stage I, mainly Artemia nauplii in stages II-VI, gradually increasing shrimp flakes in stages VII-XI, and feeding egg custard and shrimp flakes during the larval stage. Pond transfer is carried out when ammonia nitrogen ≥2 mg / L or nitrite ≥0.5 mg / L. Larval desalination is achieved by adding fresh water daily to reduce salinity to 3‰. This invention is suitable for large-scale seedling cultivation, significantly improving larval survival rate and growth rate, and is characterized by high efficiency and ecological sustainability. It can be widely applied to other aquaculture fields.
