従来、漁業の操業においては、自船周囲のより広い海域からできるだけ多くの対象生物を漁具の操作範囲に集め、漁獲に結びつけることを目的として、集魚灯が用いられている。漁業の操業過程は、対象生物を探知する過程（探魚）、誘集する過程（集魚）、漁獲する過程（漁獲）から構成され、集魚灯の灯光は漁獲の効率を左右する重要な要素である。集魚灯漁業の主な対象生物としては、走光性のあるイカ、サンマ、アジ、サバ等が挙げられる。   2. Description of the Related Art Conventionally, in fishery operations, a fishing light is used for the purpose of collecting as many target organisms as possible from a wider sea area around the ship in the operating range of fishing gear and linking it to fishing. The fishery operation process consists of a process of detecting the target organism (fishing), a process of attracting (fish collection), and a process of catching (fishing). is there. The main target organisms in the fishing lantern fishery include squid, saury, horse mackerel, mackerel, etc. that have phototaxis.

集魚灯に用いられる光源技術は、漁獲量を増加させるためには光力を増加することが有効であるという考えのもとに開発が進められてきた。集魚灯の光源は、アセチレンランプ、白熱ランプ、ハロゲンランプと変遷してきており、現在ではメタルハライドランプが主流となっている。   Development of light source technology used for fish collection lamps has been promoted based on the idea that increasing light power is effective for increasing catch. The light sources of fish lamps have changed from acetylene lamps, incandescent lamps, and halogen lamps. Currently, metal halide lamps are the mainstream.

次に、集魚灯２について説明する。図４（ａ）は、実施の形態（１）に係る集魚灯２の斜視図であり、図４（ｂ）はそのＡ−Ａ断面図である。この集魚灯２は、円柱状の筐体２２の周面に、複数の発光ダイオード２１が取り付けられ、光を全方位に出射可能となっている。また、集魚灯２には取り付け器具２４が設けられ、ワイヤー４１により海中に投入して用いられる。そして、集魚灯２と光源制御部１とは入出力線２３で接続され、各発光ダイオード２１の制御のための信号が送られる。なお、図４では便宜上、図１で示した傘部２９は省略している。   Next, the fish collection lamp 2 will be described. Fig.4 (a) is a perspective view of the fish-collecting lamp 2 which concerns on embodiment (1), FIG.4 (b) is the AA sectional drawing. In this fish lamp 2, a plurality of light emitting diodes 21 are attached to the peripheral surface of a cylindrical casing 22, and light can be emitted in all directions. Further, the fish lamp 2 is provided with a mounting device 24, which is used by being inserted into the sea by a wire 41. The fish lamp 2 and the light source controller 1 are connected by an input / output line 23, and a signal for controlling each light emitting diode 21 is transmitted. In FIG. 4, for convenience, the umbrella portion 29 shown in FIG. 1 is omitted.

図４（ｂ）に示すように、それぞれの発光ダイオード２１は、発光ダイオード実装基板２６上に配設されている。そして、発光ダイオード２１の一部と発光ダイオード実装基板２６の表面には防水シリコン２７がコーティングされ、防水処理が施されている。   As shown in FIG. 4B, each light emitting diode 21 is arranged on a light emitting diode mounting substrate 26. A part of the light emitting diode 21 and the surface of the light emitting diode mounting substrate 26 are coated with waterproof silicon 27 to be waterproofed.

また、集魚灯２には、海水を通じて発光ダイオード２１を冷却するための貫通孔２５が設けられている。具体的には、図４（ｂ）に示すように、円柱状の筐体２２の長さ方向に沿って貫通孔２５が形成されており、集魚灯２を水中へ沈めた際に海水が貫通孔２５内へ自然に流入することを利用して、発光ダイオード２１を冷却し、発光効率を高めている。   In addition, the fishlight 2 is provided with a through hole 25 for cooling the light emitting diode 21 through seawater. Specifically, as shown in FIG. 4B, a through hole 25 is formed along the length direction of the cylindrical housing 22, and seawater penetrates when the fish lamp 2 is submerged in water. The light emitting diode 21 is cooled by utilizing the natural flow into the hole 25, and the luminous efficiency is increased.

この実施の形態（１）では、発光ダイオード２１は、図４（ｂ）の拡大図に示すように、赤色発光ダイオード２１１、青色発光ダイオード２１２、及び緑色発光ダイオード２１３を内蔵している。三色の発光ダイオードの発光量をそれぞれ制御することにより、それらの合成として、発光ダイオード２１から発せられる見かけの発光波長を、あるいは発光ダイオード２１の発光強度を変化させることができる。その結果、光源２０全体としての調色、調光を自在に行うことができる。   In this embodiment (1), the light emitting diode 21 incorporates a red light emitting diode 211, a blue light emitting diode 212, and a green light emitting diode 213 as shown in the enlarged view of FIG. 4B. By controlling the light emission amounts of the three color light emitting diodes, the apparent light emission wavelength emitted from the light emitting diode 21 or the light emission intensity of the light emitting diode 21 can be changed as a combination thereof. As a result, toning and dimming of the light source 20 as a whole can be performed freely.

光源制御部１、及び集魚灯２の回路構成は、図３の例に限定されることなく、適宜設計することができる。また、この実施の形態（１）では、一つの発光ダイオード２１の中に、赤色発光ダイオード２１１、青色発光ダイオード２１２、緑色発光ダイオード２１３が内蔵されている場合について述べたが、これに限定されるものではなく、それぞれ単色の赤色発光ダイオード２１１、青色発光ダイオード２１２、及び緑色発光ダイオード２１３を用い、それらを交互に敷き詰める等して配設して、光源２０全体としての調色、調光を行っても良い。   The circuit configurations of the light source control unit 1 and the fish collection lamp 2 can be appropriately designed without being limited to the example of FIG. In the embodiment (1), the case where the red light emitting diode 211, the blue light emitting diode 212, and the green light emitting diode 213 are built in one light emitting diode 21 is described, but the present invention is not limited to this. Instead, the single color red light emitting diode 211, the blue light emitting diode 212, and the green light emitting diode 213 are used and arranged by alternately laying them out to perform the toning and dimming of the light source 20 as a whole. May be.

続いて、実施の形態（１）に係る集魚灯装置を用いた集魚方法について説明する。   Then, the fish collection method using the fish collection lamp apparatus which concerns on embodiment (1) is demonstrated.

例えば、イカを集魚する際には、操業開始時にはより広い範囲のイカを誘集するために集魚灯２の発光強度を大きく設定する。そして、イカが誘集され、集魚灯２とイカとの距離が近くなると共に集魚灯２の発光強度を減じることで、誘集過程におけるイカの逃出を防ぎ、集魚灯２の近くまでイカ群が誘集されることになる。なお、発光強度を減じる方法以外にも、発光波長を、海中の透過率の低い発光波長に変化させ、その効果を魚群探知機やソナーでモニターリングする方法等も適宜採用できる。そして、集魚灯２の近くまで誘集されたイカ群に対してイカが麻痺状態となるように図５に示すような光を光源２０から出射する。具体的には、所定の発光強度を有する光の点灯と消灯とを所定の点滅周期で繰り返すように光源２０から出射する。これにより、誘集されたイカ群は水中での動きが緩慢となり一時的に運動機能が低下する麻痺状態となり、イカ釣り機によって釣上げる状態への移行が容易に可能となる。   For example, when collecting squid, the light emission intensity of the fish collection lamp 2 is set large in order to attract a wider range of squid at the start of operation. The squid is attracted, the distance between the fishlight 2 and the squid is reduced, and the emission intensity of the fishlight 2 is reduced to prevent the squid from escaping during the assembling process. Will be attracted. In addition to the method of reducing the emission intensity, a method of changing the emission wavelength to an emission wavelength with low transmissivity in the sea and monitoring the effect with a fish detector or sonar can be appropriately employed. Then, light as shown in FIG. 5 is emitted from the light source 20 so that the squid is paralyzed with respect to the squid group attracted to the vicinity of the fishlight 2. Specifically, the light source 20 emits light having a predetermined light emission intensity so as to repeat turning on and off of light with a predetermined blinking cycle. Thereby, the attracted squid group becomes paralyzed in which movement in water is slow and the motor function is temporarily lowered, and it is possible to easily shift to a state where the squid fishing machine is picked up.

なお、光源の点滅周期は０．１〜５ｓであることが好ましく、０．２〜２ｓであることがさらに好ましく、０．５〜１ｓであることが特に好ましい。点滅周期が短い場合、あるいは点滅周期が長い場合にはイカが麻痺状態とはならず光源２０から遠ざかることがあるため好ましくない。   Note that the blinking cycle of the light source is preferably 0.1 to 5 s, more preferably 0.2 to 2 s, and particularly preferably 0.5 to 1 s. When the blinking cycle is short or when the blinking cycle is long, the squid is not paralyzed and may move away from the light source 20, which is not preferable.

また、光源の点灯時間は点滅周期に対して０．３〜０．８倍であることが好ましく、０．４〜０．６倍であることが特に好ましい。点灯時間が長い場合、また点灯時間が短い場合にはイカが麻痺状態とはならず光源２０から離れて分散してしまうことがあるため好ましくない。   In addition, the lighting time of the light source is preferably 0.3 to 0.8 times, and particularly preferably 0.4 to 0.6 times the blinking cycle. When the lighting time is long or when the lighting time is short, the squid is not paralyzed and may be dispersed away from the light source 20, which is not preferable.

また、光源２０の発光強度については、漁獲対象の水産動物の種類や水産動物までの距離などに応じて、イカが麻痺状態となるような値に適宜設定することが可能ある。また、対象種の成長段階や成群状態によって異なる対光行動をソナーや魚群探知機などの超音波測定器によりモニタリングしながら設定することも可能である。   Further, the light emission intensity of the light source 20 can be appropriately set to a value such that the squid is paralyzed according to the type of fish to be caught, the distance to the fish, and the like. It is also possible to set the light-sensitive behavior, which varies depending on the growth stage and group status of the target species, while monitoring with an ultrasonic measuring device such as sonar or fish detector.

また、光源２０の発光波長については、走光性を示す漁獲対象の水産動物の種類に応じて適宜設定することが可能である。また、イカの種類はアカイカ類とヤリイカ類の場合について示している。一般にイカの眼の視物質は、波長４７０〜５００ｎｍ付近の光に高感度を示すが、イカ釣り漁業の対象となるアカイカ類、ヤリイカ類は、それぞれ異なる波長で感度の極大を示すことが知られている。集魚灯２の発光波長を、それぞれの種類のイカの分光感度が極大となる波長付近に設定することで、各種イカ類に対して点滅光により麻痺状態とすることを効率良く行うことができる。   In addition, the emission wavelength of the light source 20 can be appropriately set according to the type of aquatic animal to be caught that exhibits phototaxis. In addition, the types of squid are shown for squids and squids. In general, squid eye visuals show high sensitivity to light in the vicinity of a wavelength of 470 to 500 nm, but squids and squids, which are the target of squid fishing fisheries, are known to exhibit maximum sensitivity at different wavelengths. ing. By setting the light emission wavelength of the fishlight 2 near the wavelength at which the spectral sensitivity of each type of squid is maximized, various squids can be efficiently paralyzed by blinking light.

（実施例１）
図６に示すような海水を張った円形型水槽Ｐ（直径３８０ｃｍ、深さ１００ｃｍ、水深９０ｃｍ）の内部でスルメイカを馴致し、二時間暗順応させた後に試験を行った。試験は水槽Ｐ内のスルメイカに対して光源２０から青色光を照射することにより行った。なお、光源の発光条件は周期０．５ｓ（点灯時間０．２５ｓ、消灯時間０．２５ｓ）とした。また、光源２０には、発光色として青色、緑色、赤色の３種類のチップを備えたチップＬＥＤ（シャープ株式会社、ＧＭ５ＷＡ０６２７０Ａ）を３０個基板上に取り付けたものを使用した。なお、青色、緑色、赤色の各光源の発光波長はそれぞれ青色４６２ｎｍ、緑色５１７ｎｍ、赤色６２２ｎｍであり、光度は３０００ｍｃｄである。 Example 1
The test was performed after acclimatizing the squid in the circular water tank P (diameter 380 cm, depth 100 cm, water depth 90 cm) filled with seawater as shown in FIG. The test was performed by irradiating the squid in the water tank P with blue light from the light source 20. Note that the light emission conditions of the light source were set to a cycle of 0.5 s (lighting time 0.25 s, light extinguishing time 0.25 s). Further, the light source 20 used was one in which 30 chip LEDs (Sharp Co., Ltd., GM5WA06270A) provided with three types of blue, green, and red chips as the emission colors were mounted on the substrate. The emission wavelengths of the blue, green, and red light sources are blue 462 nm, green 517 nm, and red 622 nm, respectively, and the luminous intensity is 3000 mcd.

（実施例２）
光源の発光条件として発光色を青色、周期を０．５ｓ（点灯時間０．３８ｓ、消灯時間０．１２ｓ）とした以外は（実施例１）と同様に行った。 (Example 2)
The light emitting conditions of the light source were the same as in Example 1 except that the emission color was blue and the period was 0.5 s (lighting time 0.38 s, light extinguishing time 0.12 s).

（実施例３）
光源の発光条件として発光色を青色、周期を１．０ｓ（点灯時間０．５ｓ、消灯時間０．５ｓ）とした以外は（実施例１）と同様に行った。 (Example 3)
The light emission conditions of the light source were the same as in Example 1 except that the emission color was blue and the cycle was 1.0 s (lighting time 0.5 s, light extinguishing time 0.5 s).

（実施例４）
光源の発光条件として発光色を青色、周期を１．０ｓ（点灯時間０．７５ｓ、消灯時間０．２５ｓ）とした以外は（実施例１）と同様に行った。 Example 4
The light emitting conditions of the light source were the same as in Example 1 except that the emission color was blue and the period was 1.0 s (lighting time 0.75 s, light extinguishing time 0.25 s).

（比較例１）
光源の発光条件として発光色を青色、周期を１．０ｓ（点灯時間０．２５ｓ、消灯時間０．７５ｓ）とした以外は（実施例１）と同様に行った。 (Comparative Example 1)
The light emitting conditions of the light source were the same as in Example 1 except that the emission color was blue and the cycle was 1.0 s (lighting time 0.25 s, light extinguishing time 0.75 s).

（比較例２）
光源の発光条件として発光色を青色、周期を１．０ｓ（点灯時間０．１ｓ、消灯時間０．９０ｓ）とした以外は（実施例１）と同様に行った。 (Comparative Example 2)
The light emission conditions of the light source were the same as in Example 1 except that the emission color was blue and the cycle was 1.0 s (lighting time 0.1 s, light extinguishing time 0.90 s).

（比較例３）
光源の発光条件として発光色を青色、常に点灯させる連続点灯をさせた以外は（実施例１）と同様に行った。 (Comparative Example 3)
The light emission condition of the light source was the same as in Example 1 except that the emission color was blue and the continuous lighting was always performed.

実施例１〜４においては、光源の点灯直後光源を避けるように光源と逆の象限へ移動し、群れではなく個々に段々光源へ近づき、その後徐々に表層に浮き光源直下の直射域に密集した。その際、スルメイカは一種の麻痺状態を示した。一方、比較例１及び２においては、光源直下の照射域に接近することはなく、水槽内の周縁に分散した。また、比較例３においては光源から離れた位置に集まることが明らかとなった。   In Examples 1 to 4, the light source is moved to a quadrant opposite to the light source so as to avoid the light source immediately after the light source is turned on. . At that time, the squid showed a kind of paralysis. On the other hand, in Comparative Examples 1 and 2, it did not approach the irradiation area directly under the light source, but was dispersed on the periphery in the water tank. In Comparative Example 3, it was revealed that the light gathers at a position away from the light source.

（実施例５）
光源の発光条件として発光色を緑色、周期を０．５ｓ（点灯時間０．２５ｓ、消灯時間０．２５ｓ）とした以外は（実施例１）と同様に行った。 (Example 5)
The light emitting conditions of the light source were the same as in Example 1 except that the emission color was green and the period was 0.5 s (lighting time 0.25 s, light extinguishing time 0.25 s).

（比較例４）

The light emission conditions of the light source were the same as in Example 1 except that the emission color was red and the cycle was 0.5 s (lighting time 0.25 s, light extinguishing time 0.25 s).

実施例５においては、実施例１と同様に、光源２０の点灯直後光源２０を避けるように光源２０と逆の象限へ移動し、群れではなく個々に段々光源へ近づき、その後徐々に表層に浮き光源直下の直射域に密集した。その際、スルメイカは一種の麻痺状態を示した。その際、スルメイカの行動が麻痺しており、光源への密集と離散を緩慢な周期で繰り返していた。一方、比較例４においては、赤色の発光に対して顕著な走光性を示さないことが分かった。   In the fifth embodiment, as in the first embodiment, the light source 20 is moved to a quadrant opposite to the light source 20 so as to avoid the light source 20 immediately after the light source 20 is turned on, approaching the light source step by step instead of a group, and then gradually floating on the surface layer. It was dense in the direct area directly under the light source. At that time, the squid showed a kind of paralysis. At that time, the activity of the squid was paralyzed, and the crowding and dispersal of the light source were repeated in a slow cycle. On the other hand, it was found that Comparative Example 4 did not show significant phototaxis with respect to red light emission.
