: Model was developed to estimate the production carrying capacity of water bodies based on nutrient inputs from aquacultures, flushing rates and the risk of algal blooms for Shallow-Water Tidal Embayments. Model was applied to Ben Beo bay, Cat Ba island, Hai Phong.The calculations suggest that nutrient loadings from cage-culture practices in 2017 were greater than the carrying capacity of Ben Beo during low and average tidal exchange. The emission of nutrients by fish cultures in 2008 into water body was greater than the sustainable carrying capacity. The aquaculture production in Plan has not overcome Ben Beo’s carrying capacity even during low tidal exchange. However, during neap tide, carrying capacity has been able to overcome
