英文摘要：

It is one of the key projects in fish cage design and calculation to predict the change of cage shape resulting from currents, since low anti-current characteristics of the cage brings some severe effects on fish farming. In this paper, a nonlinear finite element method （FEM） is employed to determine the anti-current characteristics of the cage by solving the equilibrium configuration and tension of the cage. It is expected that some measures or methods to improve the anti-current characteristics of the cage can be found by numerical simulation instead of the model test in the flume tank and the field trial on the sea.
