| Abstract: | The effects of the direction of current on the drag on fish cages are studied in the present paper. The drags on cages of different shapes, including cylindrical, truncated conical, cuboidal and hexagonal, are compared. The drag on the truncated conical net is smaller than that on other shapes of the same area. This net shape with a small apex angle is suggested for the design of fish cages. |
