Description
浮沈式生け簀は、波浪、台風などで海水面が時化た場合、生け簀が破損して内部の養殖魚が逃げ出すのを防ぐために、海水中に沈めている。そして浮沈式生け簀には、空気と海水を出し入れし浮力を調整して昇降するための中空のパイプが取り付けられている。
このように、生け簀全体の重心位置を基準に考えると、その上方側では上部枠体及び上部中央安定体の浮力による上向きの力が作用し、その下方側では下部中央安定用錘による下向きの力が作用するため、水面が安定した穏やかな海域ばかりでなく、特に上部中央安定体の働きによって水面が波立つ海域においても、生け簀全体を上下向きに回転させるモーメントが発生することがなく、逆に、生け簀全体を上下向きに回転するのを阻止する方向にモーメントが発生するので、生け簀の昇降時に生け簀の上部側が傾くのをより確実に防止することができる。
これに加えて、立体型の浮沈式生け簀の中心部には、その上部側に上部中央安定体による上向きの力が生じるので、生け簀の昇降時に生け簀の上部側が傾くのを確実に防止することができ、空気の排出時に傾いた浮力調整室の内部に空気が残留して、浮沈式生け簀が沈下しなかったり、空気の圧入時に傾いた浮沈式生け簀の底部側に海水叉は淡水が残留して浮上しないという不都合が生じることもない等、極めて新規的有益なる効果を奏するものである。
現場近くの陸上で、浮沈式生け簀1を組み立てた後、クレーンで吊って海水中または淡水中に入れ、これを船で曳航して、所定の水域に移動する。この場合には、水面に浮くように、上部枠体2と上部中央安定体5にはそれぞれ空気を入れておき、浮力がそれぞれ働くようにしておく。

- 上部枠体と下部枠体から構成され、上部枠体の内側及び下部枠体の内側並びに上部枠体と下部枠体との間の側周面にそれぞれネットが取り付けられた生け簀において、平面からみてプラスチックパイプからなる大型の円周形の上部枠体の内部を中空に形成し、中空の内部を発泡剤からなる仕切りで複数に仕切り、仕切られた内部空間に空気及び海水の出し入れで浮力の調整を図る浮力調整室をそれぞれ設け、上部枠体の円周形中心部に立体型の生け簀全体の上部側を水面上で浮力により水平に安定させる上部中央安定体を配置すると共に、当該上部中央安定体にその周囲の円周形の上部枠体に対して複数の索状を放射状に取り付け、上部枠体の下方側に位置するプラスチックパイプからなる大型の下部枠体の円周形中心部に立体型の生け簀全体の下部側を水面下で重さにより安定させる下部中央安定用錘を、下部枠体に複数の索状によって側面からみて下向きにV字型に撓んだ状態で取り付けて配置し、上部枠体の各浮力調整室の上部に空気の出し入れのための空気出入用パイプを設けると共に空気出入用パイプに開閉弁を取り付け、各浮力調整室の下部に海水叉は淡水の出し入れのための水出入用ホースを下向きに突出して設け、水出入用ホースの他端は水中に開通して没していることを特徴とする浮沈式生け簀。
