By considering the structure of Scallop's body, density of inorganic suspended particle and dissolved oxygen (DO) are the main factors that influence the environmental tolerance of the Scallop and the ability on purification by filtrating. By building a model of the Scallop's filtration process, using Scallop's soft body mass, and water temperature, salinity, DO density, inorganic suspended particle density, it is possible to decide the Scallop's tolerance against anoxic water and inorganic suspended particle by developing a biological model. Under condition of anoxic water (DO density under 2.0mg/L), the Scallop's subsistence condition would be determined only by the tolerance of DO density and the density of inorganic suspended particle does not affect. When the condition of high turbidity lasts more than a day, and the surrounding water is hypoxia (DO density under 5.0mg/L), Scallop starts to decrease from small individuals by the influence of the inorganic suspended particle. However under condition of saturated oxygen, death will not occur in any level of the inorganic suspended particle density.
