the first means is as follows: and (3) layered culture, namely putting fish fries in the main cage 10, culturing the fish fries, inputting gas into the air bag 61 through the air pipe 63 by connecting the air pump with the valve 64 after the fish fries enter the laying period, so that the air bag 61 is in an inflated state to communicate the main and auxiliary cages, enabling the adult fish to enter the auxiliary cage 30 with the mesh smaller than the roes of the adult fish, enabling the adult fish to enter the main cage 10 after the adult fish produces the roes in the auxiliary cage, then discharging the gas in the air bag 61 to close the middle through holes and further limit the adult fish by utilizing the passability of the through holes in the middle of the connecting air plate 62, and finally collecting and catching or continuously culturing the adult fish in the main cage 10 to realize a layered culture mode.
The second means: the method is characterized in that a culture mode is not adopted, the cultured objects can freely move in the main net cage 10 and the auxiliary net cage 30, when typhoon weather occurs, most of the cultured objects are concentrated in the auxiliary net cage 30 through bait throwing or other modes, the air bags 61 are deflated to form a state that the auxiliary net cage 30 is not communicated with the main net cage 10, the cultured objects are concentrated below the whole body of the culture net cage to increase the gravity center of the culture net cage, the integral stability of the culture net cage is maintained, and the loss of the net cage culture mode caused by the influence of severe weather is avoided.
