本発明は、マダイやヒラメなどを大規模な海洋牧場に8
いて養殖する魚類の養殖方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for growing red sea bream, flounder, etc. on a large-scale marine farm.
This article relates to a method for cultivating fish.
従来、海洋牧場に2いて大規模養殖を行う場合、養殖魚
の海洋牧場からの脱出を防止するために、様々な手法が
採られており、最も一般的には、網を用いる手法がある
が、これは網目体が風浪によって損傷し効く、網の保守
、維持に多大な労力と費用とを要するため、最近では網
を用いることなく、魚類に対する威嚇効果全利用する手
法が考えられている。Conventionally, when carrying out large-scale aquaculture on ocean farms, various methods have been used to prevent farmed fish from escaping from the ocean farm, and the most common method is to use nets. This is because the net is damaged by wind and waves, and it requires a great deal of effort and expense to maintain and maintain the net.Recently, methods have been considered that utilize the full effect of intimidating fish without using a net.
その1例として、音を利用する手法があり、これは水中
に8いて、ある周波数の音を発生させて魚類を威嚇し、
養殖魚の海洋牧場からの脱出を防止するものである。One example is a method that uses sound, which involves being underwater and emitting sounds at a certain frequency to intimidate fish.
This prevents farmed fish from escaping from marine farms.
ところが、水中に音波全長時間発生させていると、環境
音として魚類に慣れが生じ、魚類に対する威嚇効果が薄
れ、養殖魚の海洋牧場からの脱出を十分にかつ確実に防
止することができないという問題点がある。However, if sound waves are emitted underwater for a full period of time, fish will become accustomed to the sound as an environmental sound, reducing its intimidating effect on fish, and the problem is that it will not be possible to sufficiently and reliably prevent farmed fish from escaping from marine farms. There is.
そこで、本発明は前記の点に留意してなされ、音の威嚇
効果の薄れを防止し、養殖魚の海洋牧場からの脱出を確
実に防止できるようにすることを目的とする。Therefore, the present invention has been made with the above-mentioned points in mind, and an object of the present invention is to prevent the threatening effect of sound from fading and to reliably prevent farmed fish from escaping from a marine farm.
つぎに、前記目的を達成するための手段を、実施例に対
応する第1図ないし第3図音用いて説明する。Next, means for achieving the above object will be explained using FIGS. 1 to 3 corresponding to the embodiment.
すなわち、本発明は、放牧前に、学習用のいけす(31

ことを特徴とするものである。That is, the present invention provides a study cage (31
3, give air stimulation and sound of a predetermined frequency to the cultured fish at the same time for a predetermined period of time, and then send the sound of the predetermined frequency to the swimming cutoff section 12) using an underwater speaker α1 to screen the cultured fish. It is characterized by grazing on the generated marine pasture fi+.

の音を忌避して遊泳遮断部12:に接近することがなく
、従来のような音の威嚇効果の薄れが防止される。[Effect] Therefore, according to the present invention, for cultured fish before grazing,
Electrical stimulation and sound of a predetermined frequency are continuously applied simultaneously for a predetermined period of time in a learning cage (3), and the cultured fish before being stocked learn that electrical stimulation is present where the sound of the predetermined frequency is present. Therefore, after learning, the cultured fish are cut off from swimming i1.
Even if the farmed fish are grazed on the ocean farm (1) in which the sound of the predetermined frequency is generated in the form of a screen at 2', the farmed fish avoid the sound of the predetermined frequency and do not approach the swimming cutoff part 12:, This prevents the conventional threatening effect of sound from fading.
つぎに、本発明金、その実施例を示した歯面とともに詳
細に説明する。Next, the metal of the present invention and its embodiments will be explained in detail together with the tooth surfaces shown.

The sound is amplified by Vc and input to each underwater speaker αQ, and the sound of the predetermined frequency is generated from each underwater speaker αG in a screen shape.

111激と所定周波数の音を同時に与える。When the farmed fish are grazed on the 1i3 western farm il+, prior to grazing, all the farmed fish are placed in a learning cage (3
), housed in a fish tank +31, and fed the farmed fish with electricity of 4.
111 and a sound of a predetermined frequency are given at the same time.

The equipment shown in BL is operated intermittently, and the power supply (21
The oscillator (7) is activated when the current is on, and stimulation is generated by the electric field that is generated intermittently between the two magnetic poles (5a) and (5b), and the oscillator (7) is activated intermittently from the underwater speaker (9). At the same time, sound is given to the cultured fish in the cage (3).

l m, for a young red sea bream with a body length of 1 tM, it is 70 x 9 body length 1 (for a young flounder of 77+, it is 9
A voltage of °Y is appropriate.
ところで、電気刺激と所定周波数の音を同時に与えられ
た養殖魚は、前記所定周波数の音のあるところに眠気刺
激があることを学習する。By the way, farmed fish that are given electrical stimulation and sound at a predetermined frequency at the same time learn that a drowsy stimulus is present where the sound at the predetermined frequency is present.

習時間が’l’ 4間になれは、忌避率はほぼ100%
で砲相し始め、弗5図から1時間の学習で十分な効果が
得られることがわかる。In order to investigate this learning effect, we measured the relationship between the learning time and the repellency rate of farmed fish in response to electric stimulation and the frequency of the predetermined frequency, as shown in Figure 5, and the learning time was 'l' 4 In between, the repellency rate is almost 100%.
From Figure 5, it can be seen that a sufficient effect can be obtained with one hour of study.
従って、いけす(3)内に3いて、養殖魚にヌ寸し、電

学習する。Therefore, by keeping the cultured fish in the cage (3) and applying electrical stimulation and the sound of the predetermined frequency for the above-mentioned T time, 100% of the fish can be grown. However, it learns that there is electrical stimulation wherever there is a sound of the predetermined frequency.

する4m魚はほとんどない。Then, the farmed fish learned from this process were used as an underwater speaker α.
When the fish are grazed on the ocean farm (1) where the sound of the predetermined frequency is generated in the form of a screen at swimming barrier #glIs+21 by G, due to the learning effect, the cultured fish avoids the combined sound of the predetermined frequency from the underwater speaker 00, and the swimming barrier section (There are almost no 4m fish that escape from 21.
このとき、学習の有無による音の威嚇効果のちがい全調

測定したところ、学習していない魚及び学習した養殖魚

す工うになった。At this time, in order to fully investigate the difference in the threatening effect of sound depending on the presence or absence of learning, we measured the flash maintenance of the grazing period and the blocking rate under the condition that the swimming blocking section 121 generated sound from the underwater speaker αO. The interception rates of fish that have not been tested and cultured fish that have learned are as shown by the dashed-dotted line and solid line in Figure 6, respectively.

なる。In other words, in the case of farmed fish that have not learned, they quickly get used to the sound from the underwater speaker αO, the threatening effect of the sound fades in a short period of time, and the blocking rate rapidly decreases within a short period of time after being grazed. In the case of farmed fish, learning prevents the threatening effect of the sound from fading, and a high blocking rate continues for a long period of time, making it possible to reliably prevent the farmed fish from escaping from the 1-yo farm (1).

) in the sea urchin (1) swimming! ! ff1s +21,
two electrode rows (13a) each formed with a plurality of rod-shaped gold electrodes arranged at approximately equal intervals and electrically connected;
(jab) are arranged in parallel, and a power supply (16) is installed in the control circuit 41 to drive both electrode arrays (Hla) and (13b
) to form an electric field with a predetermined electric field strength between the underwater speaker αG
It is effective to suppress the decline in learning effect by using it in conjunction with sound.

。Grazing...J's cultured fish are placed in a learning cage and given electrical stimulation and a synchronized sound of a predetermined frequency for a predetermined period of time. Since it is possible to make the fish learn that there is a stimulus, even if, after learning, the farmed fish are grazed on a marine farm where the swimming cut-off part generates the sound of the predetermined frequency in the form of a screen, the farmed fish will not hear the sound of the predetermined frequency. By avoiding the sound and not approaching the swimming barrier, it is possible to completely prevent the threatening effect of the conventional sound from fading, and to use the threat of sound to reliably prevent farmed fish from escaping from the marine farm. It becomes possible to do so.
