Cage culture of fine grass with green material with the implementation of feeding, is conducive to regulating the nutritional needs of fish, thereby enhancing the growth rate of fish. However, due to the general setting of cages in large lakes, reservoirs, rivers, the surface is wide, storms, concentrate is often easy to lose.
