The invention discloses a method for cultivating the sipunculus nudus in a pond. The sipunculus nudus is low in the level of the food chain, is high in stress resistance, is fast in growth, belongs to the local ecological plant formation, is stable in resources group, is high in natural distribution density, small in activities range, and is free of the phenomenon of long-distance migration, thereby being very suitable for the artificial cultivation. However, the current artificial culture is low in survival rate, growth speed and yield. According to the characteristics of the different growth stage of the sipunculus nudus, a proper growth cultivation environment is creased in a nichetargeting way, the pond intermediate cultivation technology of the sipunculus nudus is combined with the pond cultivation technology of the sipunculus nudus, the survival rate of the seeds is improved, the seedling quantity per unit area is increased, the artificial breeding quality is guaranteed, and thecultivating survival rate and the cultivating per unit yield are improved, so that the cultivating survival rate reaches at 85%, the cultivating per unit yield reaches at 215kg / mu, and the aim of thehigh-efficiency cultivation of the sipunculus nudus is realized.
