英文摘要：

The fish farming and aquaculture industry are expanding,and more fishing farms are being located offshore,as the number of suitable near-shore locations is limited.This calls for new technological challenges,as fish farms are being installed at location more exposed to waves and current.Thus,knowledge of their hydrodynamic behavior under the action of waves and currents is important for the design and management of net cages in the open sea.There are many types of net cages,among which gravity cages are the most popular.Thus,in this paper,information on the hydrodynamic behavior of net cages in the open sea is focused on gravity cages.The main methods used for research into hydrodynamic behavior are introduced： physical tests and numerical simulation.For the physical experimental method,the contents in the paper include Modeling criteria for fishing nets in experiments and Scanning method for sea cage motion.For the numerical simulation,the contents in the paper include Numerical model of the float collar and fishing net,Numerical model of a single gravity cage,Calculation of velocity reduction behind a plane fishing net and so on.The researches of this paper will lead to a better understanding of the hydrodynamics of net cage in the open sea.
