Description

本発明は、魚の鎮静化装置に係り、特に、水揚げした魚を暴れないように静かにさせる魚の鎮静化装置に関する。   The present invention relates to a fish calming apparatus, and more particularly to a fish calming apparatus that quiets a landed fish so as not to be exposed.

一般に、魚の水揚げの際に魚が暴れると魚の体内に乳酸が溜まり味が落ちるため、従来から、水揚げする魚を鎮静化するために電気ショックを利用して鎮静化をはかることが実行されている。   In general, when a fish is exposed when the fish is landed, lactic acid accumulates in the body of the fish and the taste of the fish falls. .

例えば、水中に設置した電極間に通電して、電極間に存在する魚類に電気ショックを与えて鎮静化する手法が提案されている。   For example, a method has been proposed in which electricity is passed between electrodes installed in water and the fish existing between the electrodes is subjected to electric shock to calm down.

一例として、海水中においては、海水が魚類より電気伝導度が高いので、単に電極間に通電しても海水中の魚には電流が流れないために、水中の魚に通電可能な電極機能を備えた網部に通電することによって網部の近くを遊泳する魚に電気ショックを付与して鎮静化させ、鎮静化状態にある魚を網部に取り込んで水中より取り上げることが提案されている（特許文献１参照）。   As an example, in seawater, seawater has higher electrical conductivity than fish, so even if electricity is passed between the electrodes, no current flows through the fish in the seawater. It has been proposed to energize the fish swimming near the net part by energizing the provided net part and sedate it, and take the fish in the sedated state into the net part and take it up from the water ( Patent Document 1).

また、水揚げ用網をもって海中より脊椎を有する複数の魚を纏めて掬い揚げ、全部の魚が海中から空中に取り出された後に、水揚げ用網に設置された２極の電極に通電して全部の魚に当該魚の体表面に付着している海水を通して通電して、当該魚を脊椎が損傷しない程度に感電させて鎮静化させ、その後水揚げ用網から鎮静化状態の魚を次工程に供出することも提案されている（特許文献２参照）。   In addition, a plurality of fish having vertebrae are collected from the sea with a net for landing, and after all the fish have been taken out of the sea into the air, the two pole electrodes installed in the landing net are energized. Energize the fish through the seawater adhering to the surface of the fish body so that the fish is electrocuted and sedated to the extent that the spine is not damaged, and then deliver the sedated fish from the landing net to the next process Has also been proposed (see Patent Document 2).

しかしながら、特許文献１に示す鎮静化方法は、網と直接接触していない海水中の魚に電気ショックを付与する方式であるために、魚に対する通電電力を過大に設定する必要があり、過大な電気ショックを受けた魚においては、脊椎が折損したり、折れた部位の近傍に内出血が発生する等の不都合があった。   However, since the sedation method shown in Patent Document 1 is a method of applying an electric shock to fish in seawater that is not in direct contact with the net, it is necessary to set the energization power to the fish excessively, In fish that have received an electric shock, the spine is broken or internal bleeding occurs in the vicinity of the broken part.

また、特許文献２に示す鎮静水揚げ方法は、空中において魚に付着した水分とタモ網内で互いに接触し合う複数の魚自体を介して通電するものであるため、魚への通電の安定性に欠けるおそれがあった。   Moreover, since the calm watering method shown in patent document 2 energizes through the water which adhered to the fish in the air and several fish itself which contacts mutually in a turtle net, it is in the stability of the electricity supply to a fish. There was a risk of chipping.

本発明は、このような点に鑑みてなされたものであり、複数の魚を纏めて水揚げする際に、脊椎の折損や内出血を発生させることなく確実に鎮静化することができる魚の鎮静化装置を提供することを目的とするものである。   The present invention has been made in view of the above points, and a fish sedation apparatus that can reliably sedate without causing breakage of the spine or internal bleeding when a plurality of fish are landed together.

図１ないし図３は、本発明の実施形態を示すものであり、魚の鎮静化装置１は、一例として図示しない漁船の甲板に設置されている。   1 to 3 show an embodiment of the present invention, and a fish calming apparatus 1 is installed on a deck of a fishing boat (not shown) as an example.

魚の鎮静化装置２は、魚を投入する上部開口６を備えたホッパ４を有している。このホッパ４の下方から魚の移動方向下流側にかけては、魚の移動方向下流側ほど低位に位置するように傾斜配置された平板状の魚滑落板８が配設されており、この魚滑落板８は、ステンレスのような導電材料により形成されている。この魚滑落板８は、一例として水平方向に対し約１７度の角度をもって配設されており、前記ホッパ４から投入された魚が自重により滑落されるようになっている。また、この魚滑落板８は、図示しない公知の駆動装置により傾斜角度を調整されるようになっている。さらに、前記魚滑落板８の両側には、魚の落下を防止する側板（図示せず）が立設されている。   The fish calming apparatus 2 has a hopper 4 having an upper opening 6 for feeding fish. From the lower side of the hopper 4 to the downstream side in the movement direction of the fish, a plate-shaped fish slide board 8 is disposed so as to be positioned lower on the downstream side in the movement direction of the fish. It is made of a conductive material such as stainless steel. As an example, the fish sliding board 8 is disposed at an angle of about 17 degrees with respect to the horizontal direction, and the fish thrown in from the hopper 4 is slid down by its own weight. Further, the angle of inclination of the fish sliding plate 8 is adjusted by a known driving device (not shown). Further, side plates (not shown) for preventing the fish from dropping are provided on both sides of the fish sliding plate 8.

魚の移動方向における前記魚滑落板８の下流側には、魚の鎮静化装置２により鎮静化された魚を投入する開口１２（図２）を備えた底板１０が配設されている。   On the downstream side of the fish sliding plate 8 in the direction of fish movement, a bottom plate 10 having an opening 12 (FIG. 2) through which the fish calmed by the fish calming device 2 is placed is disposed.

前記魚滑落板８の上方には、複数本の可撓性線状電極１４，１４…を、縦横、すなわち魚の移動方向とこの移動方向に直交する方向の両方向にそれぞれ複数ずつ格子状に配置されるように支持する平板状の電極枠たる電極支持板１６が、前記魚滑落板８とほぼ平行に位置するように傾斜配置されている。この電極支持板１６は、前記魚滑落板８との間隔ならびに傾斜角度をそれぞれ調整可能となるように、図示しない公知の駆動装置に接続支持されている。   Above the fish slide plate 8, a plurality of flexible linear electrodes 14, 14,. An electrode support plate 16 that is a flat electrode frame that supports the slant is arranged so as to be substantially parallel to the fish slide plate 8. The electrode support plate 16 is connected and supported by a known drive device (not shown) so that the distance and the inclination angle from the fish slide plate 8 can be adjusted.

前記各可撓性線状電極１４は、ステンレスのような導電材料により可撓性を得られるような太さに形成されている。また、前記各可撓性線状電極１４は前記電極支持板１６に揺動自在に支持されており、したがって、特に魚が接触しない状態においては、鉛直方向に垂設されることになる。この状態において、各可撓性線状電極１４の先端と前記魚滑落板８とは間隔を有するように設定される。なお、前記各可撓性線状電極１４は前記電極支持板１６に揺動自在に支持されていることにより、魚滑落板８上を滑落する魚との接触時間を長くすることができ、魚を確実に鎮静化することができる。   Each of the flexible linear electrodes 14 is formed to have a thickness such that flexibility can be obtained by a conductive material such as stainless steel. Each of the flexible linear electrodes 14 is swingably supported by the electrode support plate 16 and is thus suspended vertically, particularly when no fish is in contact. In this state, the tip of each flexible linear electrode 14 and the fish sliding plate 8 are set to have a gap. Each flexible linear electrode 14 is swingably supported by the electrode support plate 16 so that the contact time with the fish sliding down on the fish slide plate 8 can be extended. Can be surely sedated.

前記各可撓性線状電極１４と、前記魚滑落板８との間には、図示しない電源ならびに電気制御装置により所望のときに通電されるようになっており、この通電のときの電圧、電流などは任意に設定できるようになっている。   Between each of the flexible linear electrodes 14 and the fish sliding plate 8 is energized when desired by a power source and an electric control device (not shown), and the voltage at the time of energization, Current etc. can be set arbitrarily.

前記ホッパ４と前記電極支持板１６との間には、ホッパ４の上部開口６から投入される魚の大きさ（三次元形状）を計測するセンサ１８が配設されており、このセンサ１８は、図示しないＬＳＩ（大規模集積回路）のような制御装置と接続されている。前記制御装置によるセンサ１８による魚の三次元形状に基づいて制御装置が前記各可撓性線状電極の高さ、すなわち電極支持板１６の高さを制御するようになっている。前記魚滑落板８の傾斜角度もセンサが検出した魚の大きさにより魚が滑落しやすく、かつ魚に付着した水分を介しての通電を安定的に行いやすくする角度に設定される。   Between the hopper 4 and the electrode support plate 16, a sensor 18 for measuring the size (three-dimensional shape) of the fish thrown in from the upper opening 6 of the hopper 4 is disposed. It is connected to a control device such as an LSI (Large Scale Integrated Circuit) (not shown). The control device controls the height of each flexible linear electrode, that is, the height of the electrode support plate 16 based on the three-dimensional shape of the fish by the sensor 18 by the control device. The inclination angle of the fish slide plate 8 is also set to an angle that makes it easy for the fish to slide down depending on the size of the fish detected by the sensor and facilitates stable energization through the moisture attached to the fish.

また、前記ホッパ４に投入される魚は、同種のほぼ三次元形状の類似するものであることが、通電が安定的に行われるために好ましい。   Moreover, it is preferable that the fish thrown into the hopper 4 is of the same kind and has a similar three-dimensional shape, so that energization is stably performed.

つぎに、前述した実施形態の作用について説明する。   Next, the operation of the above-described embodiment will be described.

本実施形態の魚の鎮静化装置２が漁船の甲板に設置されている場合、漁獲された魚の魚種や大きさを事前に分別し、同一魚種でほぼ同じような大きさの魚をホッパ４の上部開口６から投入する。すると、センサ１８が魚体の大きさ（三次元形状）を計測して、この計測値を制御装置（図示せず）が演算し、魚体の大きさに応じた電極支持板１６の高さ、魚滑落板８の傾斜角度、魚に電気ショックを与えるための電気的数値の制御などを行う。ない、これらの調整は、１バッチの複数尾の魚ごとに行えばよい。   When the fish calming apparatus 2 of the present embodiment is installed on the deck of a fishing boat, the fish species and size of the fish that have been caught are sorted in advance, and the fish of the same fish type and the size that is almost the same is selected. From the upper opening 6. Then, the sensor 18 measures the size (three-dimensional shape) of the fish body, and a control device (not shown) calculates the measured value, and the height of the electrode support plate 16 corresponding to the size of the fish body, the fish Control of the inclination angle of the sliding plate 8 and electrical numerical values for applying an electric shock to the fish are performed. None of these adjustments may be made for each batch of multiple fish.

前述したようにして、電気制御装置をＯＮにした状態で同一魚種でほぼ同じような大きさの魚をホッパ４の上部開口６から投入すると、投入された各魚が魚滑落板８を滑落する。このとき、魚滑落板８上に魚滑落板８と間隔をもって対向している複数の格子状配置された可撓性線状電極１４のいずれか複数の先端に接触し、接触した可撓性線状電極１４を揺動および撓ませるようになる。このとき、接触している可撓性線状電極１４と魚滑落板８との間に魚の表面に付着している水分を介して電流が流れ、魚に電気ショックを与える。この結果、電気ショックを受けた各魚は失神し、鎮静化される。しかも鎮静化される魚は、１尾ずつ魚滑落板８上を滑落しているので、魚同士が絡み合ったりして生じる骨折を防止することができる。   As described above, when the same type of fish of the same size and the same size are introduced from the upper opening 6 of the hopper 4 with the electric control device turned on, each inserted fish slides down the fish slide plate 8. To do. At this time, the flexible wire is in contact with the plurality of tips of the plurality of grid-shaped flexible linear electrodes 14 facing the fish slide plate 8 with a space on the fish slide plate 8. The electrode 14 is swung and bent. At this time, an electric current flows through the moisture adhering to the surface of the fish between the contacted flexible linear electrode 14 and the fish sliding plate 8, and an electric shock is given to the fish. As a result, each fish that has received an electric shock is fainted and sedated. Moreover, since the fish to be sedated slides down on the fish sliding board 8 one by one, it is possible to prevent a fracture that occurs when the fish are entangled with each other.

鎮静化された各魚は、底板１０の開口１２を介して所望の収納場所に収納される。   Each sedated fish is stored in a desired storage location through the opening 12 of the bottom plate 10.

このように本実施形態の魚の鎮静化装置によれば、漁獲された魚を確実に鎮静化することができ、しかも魚の骨折などを回避できるので、商品価値の高い魚を得ることができる。   As described above, according to the fish calming apparatus of the present embodiment, the fish caught can be calmed down reliably, and further, a fish fracture can be avoided, so that a fish with high commercial value can be obtained.

なお、本発明は、このような構成に限定されるものではなく、必要に応じて種々の変更が可能である。本発明の魚の鎮静化装置は、漁船に設置するばかりでなく、陸上に設けることももちろん可能である。     In addition, this invention is not limited to such a structure, A various change is possible as needed. The fish calming apparatus of the present invention can be installed not only on a fishing boat but also on land.
