The present invention in the process of growing the fry from the sea cages to the medium rearing fish, after generating a signal of a specific frequency, the reflexive learning to spray artificial feed repeatedly learning for a certain period of time to the fish family sequential adaptation process to the natural environment The present invention relates to a marine ranching sound feeding device that increases the survival rate of the reared fish stocked in the sea. More specifically, each acoustic feeding device installed in a plurality of buoys floating in the sea is controlled by radio signals on land. A land control station can be established to enable the two-way communication between the land control station and the sound feeder so that remote control of the sound feeder on the sea can be achieved. The present invention relates to a control system for a marine ranch acoustic feeding device and a control method thereof.

Recently, Korea's coastal and offshore fisheries have been devastated due to the establishment of exclusive economic zone (EEZ) of the neighboring countries and the depletion of coastal fish stocks. The company is piloting the sea ranching business, which grows from marine cages to medium reared fish and discharges them in the sea where artificial reefs are installed.

Currently, the sea ranching project, which is being piloted, is carried out by putting 7 ~ 10mm sized larvae such as sea bass, seabream and red snapper, which are inhabited offshore, into marine cages from around May to June, and then growing them as intermediate feeds. Around November, they are discharged into the sea ranch setting sea where artificial reefs are installed.

In this way, the target fish raised in marine cages need to supply 6-7 times of artificial feed per day by manpower, which not only requires a lot of manpower and budget, but also raises the intermediate reared fish grown as artificial feed in marine cages. After discharge into the artificial feed grows to natural food, the fish immediately discharged due to changes in the natural environment in the process in this process has a problem that the survival rate is lowered because the natural food intake is not easy in the area.

Therefore, it is impossible to artificially feed artificial fish after feeding them to the sea, and it is impossible not only to provide food to humans, but also to increase the efficiency of the sea ranching business because it requires huge manpower and budget. The situation is required to introduce a system that can increase the survival rate in the sequential adaptation process to the natural environment after discharge to the sea.

1 is a conceptual view of a general sea ranch, the size of 7 ~ 10mm sized larvae such as jeopbolak and red snapper inhabiting coasts with less glimpse in the cages from about 5 ~ 6 month to about 10 ~ November It is discharged into the sea ranch setting sea where artificial reefs are installed.

The discharged intermediate reared fish is subjected to the change process of finding food in the artificial reef group or natural grass through the staying grass and the induction grass, but it is not easy to ingest the natural food in the sea area during the change process of finding the food directly in the sea after being discharged. The medium reared fish discharged to the sea where the grass is installed sends out the sound that reacts and gathers near the staying grass, and then installs an acoustic feeding device that feeds the food artificially to support the changing process of finding food, thereby increasing the survival rate. It is the purpose of the sea ranch to increase the

In order to provide artificial feed until the discharged intermediate reared fish adapts to the changing process of finding natural food, it is necessary not only to have an acoustic feeding device, but also to feed the sound simultaneously with the growth of the reared middle reared fish. It must be done through learning.

Therefore, as described above, after spawning an acoustic signal of a specific frequency in water, the condition reflection learning spraying artificial feed is repeatedly learned for a certain period of time to improve the survival rate of the intermediate reared fish discharged during sequential adaptation to the natural environment. It has been proposed that the sound feeder of the sea ranch is high.
