Land-based aquaculture systems play an important role in the era of facility-based fisheries. Whether it is a full-cycle land-based recirculating aquaculture model or a land-based nursery model in deep-sea aquaculture， or land-based aquaculture in land-sea relay aquaculture models， the performance of land-based systems is critical. However， land-based aquaculture systems still face challenges in solid waste management， especially the efficient collection and removal of settleable particles like uneaten feed and feces. Accumulation of these wastes adversely impacts the stability of water quality， biological safety of cultured organisms， and production operations. To accurately and comprehensively describe the factors influencing the movement of settleable particles in aquaculture tanks， this paper focuses on reviewing the effects of hydrodynamic characteristics of aquaculture tanks， structural characteristics of the tanks， and the inherent properties of settleable particles on the movement of settleable particles. Aiming at the difficulties of removing settable particles in land-based systems， this paper proposes valuable research directions to improve the aquaculture environment， enhance fish health， and improve the water quality of the aquaculture system， thus providing theoretical support and practical guidance for production.
