超音波によるカワウ対策ーGreat cormorant measures by supersonic

Result of setting up ultrasonic device in lake by great cormorant measures
The great cormorant also approached the position of about 20m and it invaded the cultivation pond seven times on the evening of that day of the installation. It has not approached any more though it approached from the cultivation pond to the position like 100?150m from the following 5 o'clock of the evening the 10th set up to 6:30.
One approaches the position of about 30m of the cultivation pond along the stone wall where the sound wave doesn't reach.
It made a U-turn in the place called the area of the supersonic wave when approaching any more.

When you ask the installation location in will being change daytime 12 days after the installation
One person of six person fishing guild that is shall not be amusing , saying that "It is not effective, and the crow also doesn't run away".
Turning off power supply of temporary and device to proof in five places or more, and just confirmations at meat center the other day and will being seeing power supply cutting of appearance of crow

One union member (one different from saying as not effective) testified when going to remove the ultrasonic device, and the great cormorant came in daytime and [wakasagi] of the cultivation pond considerably testified yesterday when the supersonic wave was stopped ..taking...
Still, it was effective.

カワウ対策で超音波装置を湖に設置した結果
設置当日の夕方は、カワウも２０mほどの位置まで近づいて７回養殖池に侵入していました。設置１０日後の夕方５時から６時３０分までは、養殖池から１００－１５０mほどの位置まで近づきましたが、それ以上近づいて来ませんでした。
１羽は、音波の届かない石垣に沿って養殖池の３０mほどの位置まで接近。
それ以上近づくと超音波の領域と云う所でUターンして行きました。

設置１２日後、設置場所を変えようと思い昼間尋ねると
６人居た漁業組合の１人が　「効果が無いよ、カラスも逃げないよ・・・」と
おかしいな！！
カラスは、５ヶ所以上で実証済みだし、先日も食肉センターで確認したばかりなのに
取りあえず、装置の電源を切り様子を見ようと思い電源切断

超音波装置の撤去に行くと組合員の一人（効果が無いと言った方と違う方）が、超音波を止めた昨日は、昼間からカワウが来て結構養殖池のワカサギが取られたとの証言した。
やはり、効果が有った！！

The sound that the deer dislikes by the deer measures is discovered.

The sound that the deer after the experiment of three years is watched or disliked is discovered. ！！

The deer kept in the ranch gathers in the place with food with pleasure when food is put in the hedge.

Deers did not gather though food was put in the cage this time with the sound wave generation device was set up and the sound wave generated.

It did not come to eat food though the deer was pleased though the child came to give food when the sound wave had been generated in the distance.

Meanwhile, it never came to eat food though the sound wave had been generated for three hours or more.

It gathered because four hours had passed in the vicinity after the generation of the sound wave had begun in ..deer.. ..food.. eating at the same time as stopping the sound generation.

This sound wave seems to generate the caution for the deer.

Man ..sound small like sparrow's warble alone.. is not heard.

When this sound wave generation device is displayed just like the hedge, the deer doesn't approach.

As for this sound wave generation device, the sound wave extends in the direction for which the speaker is suitable at the angle of 30 times.

The longitudinal coverage of the sound wave is almost 50-80m.

The insect damage by the deer is helped with this device and the growth of the prevention tree can be helped.

Moreover, the thing that the deer dashes out to the road by the thing set up in parallel to the road is lost and the deer can be defended from the car accident.

The deer comes not to collide with the railway with the entering train by the thing set up in parallel to the railway track.

It doesn't die as the deer becomes abnormal because of the sound wave that this device is generated.

シカ対策でシカの嫌う音発見！！

３年の実験の末シカが警戒するもしくは嫌う音を発見

牧場で飼われているシカは、餌を柵の中に入れると喜んで餌の有る場所に集まって来る。

今回音波発生装置を設置し音波を発生した状態で餌を檻の中に入れたがシカは、集まって来なかった。

音波を発生している時に子供が餌を与えに来てもシカは、遠方で喜んでいたが餌を食べに来なかった。

３時間以上音波を発生していたが、その間一度も餌を食べに来なかった。

音波の発生を開始してから４時間近く経過したので音波発生を止めたと同時にシカが餌を食べに集まって来た。

この音波は、シカに対して警戒心を発生させるようだ。

人間には、雀のさえずりのような小さな音にしか聞こえない。

この音波発生装置を柵と同じように並べておくとシカは、近づいて来なくなる。

この音波発生装置は、スピーカーの向いている方向に３０度の角度で音波が広がって行く。

音波の到達距離は、おおよそ５０−８０mである。

この装置によりシカによる食害を防き、樹木の生長を助ける事が出来る。

また、道路と平行に設置する事でシカが道路に飛び出す事がなくなりシカを自動車事故から守ることができる。

線路と平行に設置する事で鉄道にシカが入り込み列車と衝突することもなくなる。

この装置が発生する音波でシカが異常になるとか死ぬことはない。
