Integrated aquaculture is defined as the polyculture of multiple aquatic species in a waters or culture of aquatic species within, or together with, the undertaking of other productive activities. Examples of the integrated culture of rice and fish have existed in China since 1800 B.C. More recently, large scale integrated mariculture was initiated in 1975. At present, there are several dozen types of integrated aquaculture in China that offer several ecological benefits, including waste reclamation through trophic relationship, maintenance of ecological balance by complementary or commensalisms of farmed species or production systems, optimization of resource use (time, space and food), and disease prevention. Integrated aquaculture can be divided into three forms: technical integration, species integration, and system integration, which consists of two sub-groups (integration of aquatic systems and integration of aquatic and land systems).
