汚染の原因にもなっていた。[Problems to be Solved by the Invention] However, since conventional automatic feeding devices feed at a constant speed for a certain period of time, a situation may occur where the feeding rate of the farmed fish school decreases but continues to be fed at the same rate. In addition to reducing feed efficiency, this was also a cause of marine pollution.
【０００５】本発明は、上記の点にかんがみてなされた
もので、その目的は、養殖魚群の摂餌状況に応じて給餌
制御を行い得る自動給餌装置を提供することである。The present invention has been made in view of the above points, and its object is to provide an automatic feeding device that can control feeding according to the feeding status of a group of farmed fish.

作を制御する給餌制御手段とを備えている。[Means for Solving the Problems] In order to solve the above-mentioned problems, an automatic feeding device according to the present invention includes a means for feeding food for cultured fish, and a method for feeding food during a feeding operation by the feeding means. a detection means for detecting feeding status of a school of cultured fish in a cage;
Feeding control means for controlling the feeding operation of the first-stage feeding means based on the detection result of the detection means.

群の摂餌状況の検知開始を指示する。[Operation] The feeding control means may be controlled at 6 o'clock, 11 o'clock, 1 o'clock, for example.
At a predetermined time such as 5 o'clock, the feeding means is activated to start the feeding operation. After continuing the feeding operation for, for example, 5 minutes, the detection means is instructed to start detecting the feeding status of the cultured fish group in the cage.

群の摂餌状況を検知する。[0008] Then, the detection means starts detecting the feeding status of the cultured fish group, for example, by the following method. In other words, when feeding is not being carried out, the cultured fish in the cage are randomly located in various locations, such as being dispersed evenly across the cage or swimming in groups. On the other hand, when feeding begins, farmed fish gather at the feeding area.
Especially in large numbers, they gather under the feeding opening of automatic feeding devices. The cultured fish that have consumed enough food then move away from the feeding port and disperse to various parts of the fish tank (particularly in the lower part). Therefore, the detection means, for example, emit an initial number of ultrasonic waves at predetermined time intervals, and if the number of reflected sounds from the cultured fish in the lower area (deep area) of the cage is a certain number or more, it is considered that the fish have been sufficiently fed. If there are many cultured fish that have moved away from the feeding port and have come to the lower area of the cage, and the number of reflected sounds from the cultured fish in the lower area (deep area) of the cage is less than a certain number, it means that they are still feeding near the feeding port. The feeding status of a school of farmed fish is detected using methods such as determining whether there are a large number of farmed fish inside.

Temporarily stop the feeding operation by
Thereafter, when the cultured fish school begins to feed actively, control is performed such as restarting the feeding operation.

Based on the clock signal from the clock circuit 4, the relay RL is turned on at predetermined time intervals to start the feeding operation by the feeding machine 1. After starting the feeding operation, the fish school sensor 3 is controlled to investigate the distribution of farmed fish, and based on the investigation result, the relay RL is turned OFF/ON to control the feeding operation of the feeding machine 1.

より、養殖魚群の摂餌状況を判断する。The fish school sensor 3 detects the presence of a school of fish by transmitting and receiving ultrasonic waves, and is composed of an ultrasonic transmitter, an ultrasonic receiver, and an ultrasonic generation circuit, and serves as a vibrator for transmitting and receiving ultrasonic waves. uses a material with a large electrostrictive effect, such as barium titanate. The ultrasonic generation circuit generates pulses under the control of the feeding controller 2 and outputs them to the ultrasonic transmitter. Then, the vibrator vibrates and emits ultrasonic waves, and the reflected sound is received by the ultrasonic receiver. Note that the dead zone in the figure means a zone in which the fish school sensor 3 cannot detect a school of fish. Also, CH-1, C
H-2,...CH-7, CH-8 each have a depth of 1.5
m ~2.5m, 2.5m ~3.5m,...7.5m ~8
．． It supports bands of 5m, 8.5m to 9.5m, and the feeding controller 2 supports CH-7 (7.5m to 8.5m)
The feeding status of a school of farmed fish is determined by counting the reflected sound from farmed fish in this band.

の混同を回避するためである。[0015] The reason why the feeding status of the cultured fish school is not judged based on the reflected sound from the cultured fish in the lowest CH-8 band is due to the difference between the sound reflected from the seabed, fish nets, etc. This is to avoid confusion.

式を採用することも可能である。[0016]Also, as a method for detecting the feeding status of a school of farmed fish, methods such as image processing using an underwater television or detection by sound can be considered, but the former has limitations in price, durability, and transparency. The latter has problems in that it is necessary to adopt acoustics depending on the fish species, fish age, and culture method.In comparison, ultrasonic detection has problems with existing inexpensive methods. Since a fish detection sensor can be used, in this embodiment, the ultrasonic school sensor 3 as described above is used.
Of course, it is also possible to use an image processing method or an audio method.

らされる。The battery 5 is used as a power source for the automatic feeding device and is charged by a solar battery 6. In other words, the fish tank is built offshore or in an inlet.
Since commercial power is not available, batteries are used and charged by solar cells so that there is no need to replace the batteries. Note that the buzzer 7 is sounded when starting the feeding operation.
【００１８】次に、給餌コントローラ２の制御動作を図

(Step F-1). Due to this buzzer sound, cultured fish reflexively gather near the feed outlet 1c of the feeder 1, and the fish tank operator can recognize from a distance that the automatic feeding device is operating normally. can do.

かを判断する（ステップＦ−６）。[0020]Next, after feeding is discharged into the cage at a constant speed for 5 minutes by the feeder 1 (step F-2), the buzzer 7 is sounded (step F-3). Then, ultrasonic waves are transmitted from the ultrasonic transmitter of the fish school sensor 3 (step F-
4), the reflected sound is received by an ultrasonic receiver (step F-5). Then, it is determined whether the setting conditions are satisfied (step F-6).

) The condition is that the number of reflected sounds from farmed fish in the deep zone becomes a certain number. In addition, CH-7 (7.5m ~
The determination as to whether the sound is reflected from a cultured fish in the deep zone (8.5 m) is made based on the time required from transmitting the ultrasonic wave to receiving the reflected sound.

給餌動作を再開する（ステップＦ−７）。As a result of the judgment in step (F-6), if the above-mentioned setting conditions are not satisfied, there are many cultured fish still feeding near the feed outlet 1c, and they have eaten enough food and have moved to the lower layer area. Since it is considered that there are few cultured fish that have come to feed, if the feeder 1 is currently off, it is turned on to restart the feeding operation by the feeder 1 (step F-7).

(Step F-8). As a result, 15 consecutive
If the feeder 1 is off for more than 1 minute, there may still be some cultured fish to feed when the feeding operation is restarted, so in order to quickly grow the cultured fish, turn on the feeder 1 for just 1 minute. After trying feeding for 1 minute (step F-9)

After minutes have elapsed, the ultrasound is transmitted and the reflected sound corresponding to the transmitted ultrasound is received, and among the reflected sounds, CH-7 (7.
The process of counting only the reflected sounds from cultured fish in the deep zone (5 m to 8.5 m) is repeated every 5 minutes. At that time, if the count value has not reached the stop level after 5 minutes, it is assumed that there are many farmed fish feeding and feeding continues, and when the count value reaches the stop level, As a general rule, feeding should be stopped as there are many farmed fish that are full. However, even if it is thought that there are many cultured fish that are full, if the feeding operation has been stopped for 15 consecutive minutes or more, try feeding for just one minute. This is because feeding is not restarted no matter how long you wait even though the fish are not full, so some farmed fish may have given up and moved to the lower layer of the fish tank. Call them to the nearby area (upper layer) and feed them until they are fully satisfied.

Reset every minute. Further, the total feeding time of 2 hours is determined in consideration of the number of cultured fish in the cage and the feed release rate by the feeder 1, so that the optimum amount of feed can be fed.

It is also possible to control. Further, it is also possible to apply the present invention to a feeding machine having a feeding start/feeding stop mechanism other than a screw conveyor. Furthermore, methods for detecting the feeding status of cultured fish schools include, for example, detecting the amount of food that falls to the lower layer of the cage without being fed by the cultured fish group, or detecting the distribution amount of the cultured fish group in the upper layer of the cage. Other methods may also be used. When detecting the distribution of the cultured fish school in the upper layer of the cage, the feeding operation may be interrupted when the number of cultured fish in the upper layer becomes less than the initial number.
