Inside the second net member 64 is a pair of space securing frames 62A formed in a closed shape to form a fish activity space, which are installed in upper and lower portions, respectively. In this case, a plurality of space keeping members may be installed between each space securing frame 62A, and the space securing frame 62A may be made alone.

In addition, the support cable 69 may support the second mesh member by connecting the subsea anchor and the second mesh member 64, but each of the space securing frames 62A and the support 67 may be a subsea anchor or an offshore structure. (10) can be supported.

On the other hand, each cage form portion 68 receives the feed supplied from the cage feed facility 90 provided in the deck portion 30 of the hybrid offshore wind farm as shown in Figures 2c and 6 And a feeding device 65 for the same.

Feeding device (65) provided in the cage culture portion 68 is connected to the offshore cage feed facility (90) and feed line (80) provided in the deck portion 30, the offshore cage feed facility (90) It is configured to feed the fish that are fed from the feed.

At this time, the feed line 80 is further provided with a subsea power cable for receiving the power required by the feeder 65 from the wind turbine 20. That is, the power cable is to be wired to be coupled with the feed line (80). However, the present invention is not limited thereto, and the power cable may be connected to each cage form 68 alone.

On the other hand, the feeder 65 is a drive screw 65A installed inside the support body 67 formed in a hollow form and the drive coupled to the lower end of the feed screw 65A to drive the feed screw 65A Supply member 65D having a drive unit 65C made of a motor, and built-in temporary storage hopper (65B) for temporarily storing the feed fed from the feed line 80 is connected to the end of the feed line 80 ) At this time, the lower portion of the transfer screw (65A) is located inside the temporary storage hopper (65B) is configured to transfer the feed stored in the temporary storage hopper (65B) to the upper, the drive motor of the drive unit is an electric motor or a hydraulic motor It is composed.

And, at the upper end of the support 67, the feed spout 65E for dispersing the feed conveyed toward the upper portion of the support 67 by the transfer screw 65A to the upper several places of the space formed by the second net member 64 A plurality of radial may be provided.
