本発明は、魚介類を体長別に選別して引き揚げる魚介類
選別引揚装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fish and shellfish sorting and hauling device that sorts and pulls fish and shellfish according to body length.
通常魚介類は、同一時期にふキ化し同一条件で育成した
場合においても、個々の成長度合が大きく異っている。Normally, even when fish and shellfish hatch at the same time and are grown under the same conditions, their individual growth rates vary greatly.
そのため、養殖場などにおいては、出荷時に所定未満の
体長のものを取り除き、所定以上の大きさの魚介類を選
別して出荷しなければならなく、従来は１尾ずつ網です
くって行う手作業である。For this reason, at farms, fish and shellfish that are smaller than a specified length must be removed before shipment, and seafood larger than a specified size must be sorted and shipped, which is traditionally done manually by scooping each fish in a net. It is.
従来は手作業であるため効率が悪く、多くの人手を要し
、コストがきわめて高いという問題点がある。Conventionally, the process has been done manually, so it is inefficient, requires a lot of manpower, and is extremely expensive.
本発明は前記の点に留意し、効率良く安価に魚介類の選
別引き揚げができる装置を提供することを目的とする。The present invention has been made with the above-mentioned points in mind, and an object of the present invention is to provide an apparatus that can efficiently and inexpensively sort and salvage seafood.
前記課題を解決するために、本発明の魚介類選別引揚装
置は、水中に配設された２個の電極と、所定以上の大き
さの魚介類が忌避する電圧が前記両電極間に印加されて
形成された電場領域と、前記電場領域側へ魚介類を追い
立てる追立網と、前記電場領域の手前に配設され追い立
てられた前記所定以上の大きさの魚介類を水から引き揚
げる引揚網とを備えたものである。In order to solve the above problems, the fish and shellfish sorting and pulling device of the present invention includes two electrodes disposed in water, and a voltage that repels fish and shellfish of a predetermined size or more is applied between the two electrodes. an electric field area formed by the electric field area, a retrieval net for driving fish and shellfish toward the electric field area, and a retrieval net disposed in front of the electric field area for pulling out the chased fish and shellfish of a predetermined size or more from the water. It is equipped with the following.
前記のように構成された本発明の魚介類選別引揚装置は
、電場領域の両電極に印加する電圧により、その電圧を
忌避する所定以上の大きさの魚介類がその領域を通過せ
ず、前記大きさ未満の魚介類がその領域を通過するため
、魚介類が所定の大きさ以上とそれ未満とに自動的に選
別され、人手を要さず、効率よく安価に選別し引き揚げ
ることができる。The fish and shellfish sorting and hauling device of the present invention configured as described above has a voltage applied to both electrodes in the electric field region, so that fish and shellfish of a predetermined size or more that avoid the voltage do not pass through the region. Since fish and shellfish smaller than the size pass through the area, the fish and shellfish are automatically sorted into those larger than a predetermined size and those smaller than a predetermined size, and can be efficiently and inexpensively sorted and salvaged without the need for manpower.
まず、本発明の原理について第２図を参照して説明する
。First, the principle of the present invention will be explained with reference to FIG.
水（１）を満たした容器（２）内の両側部に２枚の電極
（３）全平行に配設し、両電極（３）に電源（４）によ
り電圧を印加し、電場領域（５）ヲ形成し、容器（２）
内の魚（６）の感電反応を調査する。Two electrodes (3) are arranged completely parallel to each other on both sides of a container (2) filled with water (1), and a voltage is applied to both electrodes (3) by a power source (4). ) form a container (2)
Investigate the electric shock reaction of the fish (6) inside.
すなわち、容器（２）内に各種体長の魚介類を入れ、印
加電圧を種々変化し、魚介類がどのような反応を示すか
を調べる。That is, fish and shellfish of various body lengths are placed in a container (2), and the applied voltage is varied to examine how the fish and shellfish react.
例えば、マダイの場合、体長５ｃＩＲでは２．８Ｖ、１
０ａでは１．４ｖ＊ ２０ ｃｍでは０．６Ｖで「驚き
」の反応を示した。For example, in the case of red sea bream, when the body length is 5cIR, it is 2.8V, 1
At 0a, it showed a "surprise" response at 1.4V*20 cm at 0.6V.
このように、魚体の大きいもの程低い印加電圧で「驚き
」すなわち忌避反応を示し、又、魚体の小さいものはそ
の程度の電圧では何の反応も示さない。In this way, larger fish exhibit a "surprise" or repellent response at lower applied voltages, while smaller fish exhibit no response at that level of voltage.
つぎに、前記電場領域（５）の形成手段の１例を第３図

極列を形成し、電源（９）により各ブスバー（７）を介
して各電極（８）に電圧を印加し、画電極列間に電場領
域（１０）を形成する。Two busbars (7) are arranged completely parallel, and each busbar (7
), bar-shaped electrodes (8) are erected at equal intervals to form a parallel electrode array, and a voltage is applied to each electrode (8) via each bus bar (7) by a power source (9), thereby forming a picture electrode array. An electric field region (10) is formed in between.
例えば、電極列の間隔が１ｍで印加電圧が８．７５Ｖの
場合、体長１０ｍ以上のマダイを選別することができた
。For example, when the interval between the electrode rows was 1 m and the applied voltage was 8.75 V, it was possible to select red sea bream with a body length of 10 m or more.
