Due to the aging ponds and diseases such as farming, shrimp farming production and development has been severely restricted. The authors studied the culture of P.vannamei by feeding a certain amount of Trachinotus ovatus and Scyllaserrata (Forskal) to the culture of polyculture of fish, shrimp and crab Method to effectively improve the breeding ecological environment, prevent the occurrence of breeding diseases and disease spread, the breeding effect has been significantly improved, and in 2007 breeding production test was successful, the average yield of 11062.0 yuan / 667m2, a profit of 6308.5 yuan / 667m2, achieved good economic benefits.
