Abstract:

In order to further understand the application of Integrated Multi-Trophic Aquaculture (IMTA) in aquaculture industry, the paper sorted out the development history of IMTA, and outlined the main aquaculture species of IMTA, including fishes, crustaceans, bivalves, echinoderms and algae, et al. It summarized land-based and marine IMTA, and pointed out that freshwater and brackish water IMTA were part of the land-based aquaculture models, while seawater and offshore IMTA belonged to marine IMTA. The article also outlined the advantages of IMTA in terms of aquaculture environment, energy utilization, economic benefits, and reduction of waste discharge. At present, IMTA still has problems in the aspects of technical implementation, ecological impacts and sustainable development. Future research should focus on the interactions among different species components, system optimization, and disease control to promote the sustainable development of aquaculture.
