In Quang Ninh, there are two methods of marine aquaculture catering to different species: cage farming for fish and raft farming for bivalve molluscs. The floating cage farming method offers technical advantages, including ease of management, simplicity in feeding, convenience in cleaning, and good oxygen supply due to wind disturbance. However, the main limitation is the restriction of flow, leading to nutrient agglomeration near the cage. Waste from aquaculture, including uneaten food, solid waste, and inorganic and organic solutes from the excretion of cultured organisms, causes negative impacts such as eutrophication and increased nutrient emissions from the substrate, which affect the quality of the water environment. In the aquaculture industry, numerous efforts have been undertaken to mitigate organic and nutrient waste in and around cage farming areas through enhanced feed efficiency, advanced feed management systems, and other solutions. However, despite technological advancements, the issue of organic (nutrient) pollution linked with cage fish farming has not been entirely eradicated. Integrated MultiTrophic Aquaculture (IMTA) is a concept modeled after the inherent function of the food chain in the marine environment. In this food chain, each species typically finds a suitable food spectrum from the waste produced by another species. Currently, countries around the world have adopted the IMTA farming model to address organic and nutrient pollutants originating from concentrated cage aquaculture activities. However, in Vietnam, particularly in Quang Ninh province, there have been no specific studies conducted on solutions to mitigate and address organic and nutrient pollution stemming from concentrated cage farming activities in coastal areas. Based on a review of research results, the study proposes a method for designing experiments and evaluating the effectiveness of treating organic and nutrient pollutants in the IMTA farming model.
