Description

本発明は、漁船において海面を光照射して集魚する方法とそのための照明方法及びシステム並びに漁船に関するものである。   The present invention relates to a method for collecting fish by irradiating the sea surface with light on a fishing boat, an illumination method and system therefor, and a fishing boat.

従来から、漁船における集魚のための照明・配光には、漁火（かがり火）を使う方法があった。その後、光源すなわち集魚灯として、オイル灯やガス灯に替わり、自熱灯、水銀灯を経て、現在では、より効率の高いメタルハライドランプが使われている。集魚灯を使う代表的な漁業はイカ釣り漁である。沿岸で操業する２０トンクラスのイカ釣り漁船の場合、集魚灯の消費電力は自主規制にて上限（１８０ｋＷ）が決められている。   Conventionally, there has been a method using fishing fire (bonfire) for lighting and light distribution for collecting fish on a fishing boat. After that, instead of oil lamps and gas lamps as light sources, that is, fish lamps, self-heating lamps and mercury lamps are used, and metal halide lamps with higher efficiency are now used. A typical fishery that uses fishing light is squid fishing. In the case of 20-ton class squid fishing fishing boats operating on the coast, the power consumption of the fishing light is limited by voluntary regulations (180 kW).

その照明のために、裸のメタルハライドランプ（３ｋＷが主流）を６０灯程、漁船の長手方向中心軸上の甲板から２〜３ｍ上部に、金属フレームとワイヤにて吊り下げているのが一般的である。   For the lighting, 60 bare metal halide lamps (3 kW is the mainstream) are generally suspended by a metal frame and wire 2 to 3 m above the deck on the central axis in the longitudinal direction of the fishing boat. It is.

また、照明効率の向上と漁船の燃費改善を図るために、青色発光ダイオードによる面状光源を用いた集魚灯が知られている（特許文献１参照）。
特開２００３−１３４９６７号公報 Further, in order to improve the lighting efficiency and improve the fuel efficiency of a fishing boat, a fish collecting lamp using a planar light source using a blue light emitting diode is known (see Patent Document 1).
JP 2003-134967 A

上記のような裸のランプを使用した照明方法においては、次の問題があった。
（１）不均一な水中配光・・・従来の照明方法では、水中には漁船の舷と平行方向に均一で比較的多くの光が届くが、漁船の前後方向には不均一かつ比較的弱い光しか届かない。集魚灯として最適な配光になっているかどうか問題である。
（２）発電エネルギーの浪費・・・裸のメタルハライドランプでは、上方へ漏れる光が大部分を占め、上方へ漏れた光は人工衛星からも確認できる程である。下方向へ放たれる約５０％の光についても、海面での全反射、甲板での反射などを考えると、凡そ８割は水中以外へ照射されている。つまり、裸ランプはその光の約９割を無駄にしているとも言える。一方、合計１８０ｋＷの集魚灯を積んだ漁船の場合、発電の燃料は１日１，０００リットル必要とされている。この燃料のほとんどは空へ光を無駄に放つために使われていることになる。エネルギーの無駄であるだけでなく、相当の二酸化炭素が排出されていることにもなる。
（３）光害・・・サーチライトはもちろん屋外の照明から夜空に漏れる強い光は、星を見え難くするとして、「ダークスカイ運動」などの非難の的となっている。イカ釣り漁船の１８０ｋＷという光の量は、小さな球場一つ分の照明光に相当する。このような光は人工衛星からも観測されるほどである。そのため、光害の原因の一つがイカ釣り漁船の漁火であると問題視されつつある。
（４）紫外線照射・・・裸のメタルハライドランプから出る紫外線が、漁師の健康（日焼けなど）に影響を及ぼす可能性を持っている。
また、上記公報に記載されたＬＥＤ面光源を用いた集魚灯においても、効率良く集魚するための配光についての開示はない。 The illumination method using the bare lamp as described above has the following problems.
(1) Non-uniform underwater light distribution: With conventional lighting methods, a relatively large amount of light reaches the water in a direction parallel to the fishing boat's cage, but is uneven and relatively non-uniform in the longitudinal direction of the fishing boat. Only weak light reaches. It is a problem whether the light distribution is optimal as a fishing light.
(2) Waste of generated energy: In bare metal halide lamps, the light leaking upward occupies most of the light, and the light leaking upward can be confirmed from an artificial satellite. About 50% of the light emitted downward is about 80% irradiated outside the water, considering total reflection on the sea surface and reflection on the deck. In other words, it can be said that a bare lamp wastes about 90% of its light. On the other hand, in the case of a fishing boat loaded with a total of 180 kW of fishing light, 1,000 liters of fuel for power generation is required per day. Most of this fuel is used to waste light into the sky. Not only is this a waste of energy, but a considerable amount of carbon dioxide is being emitted.
(3) Light pollution: Searchlights, as well as strong light leaking from the outdoor lighting into the night sky, have been blamed for the “dark sky movement” as making it difficult to see stars. The amount of light of 180 kW from a squid fishing fishing boat corresponds to the illumination light for one small stadium. Such light is also observed from artificial satellites. For this reason, one of the causes of light pollution is being regarded as a problem that the fire of squid fishing fishing boats.
(4) Ultraviolet irradiation: Ultraviolet rays emitted from bare metal halide lamps may affect fishermen's health (sunburn, etc.).
In addition, there is no disclosure of light distribution for efficiently collecting fish even in a fish collecting lamp using the LED surface light source described in the above publication.

本発明は、上記問題に鑑みてなされたものであり、光源からの配光を改善して、魚やイカの誘引効果及び水中への照明効率を高め、誘引した魚やイカの捕獲効率の向上が図れる集魚方法とそのための照明方法及びシステム並びに漁船を提供することを目的とする。   The present invention has been made in view of the above problems, and improves the light distribution from the light source, enhances the effect of attracting fish and squid and the illumination efficiency to the water, and improves the capture efficiency of the attracted fish and squid. An object of the present invention is to provide a fish collection method, a lighting method and system therefor, and a fishing boat.

上記目的を達成するために本発明は、漁船近傍の海面を光源により漁船の左右舷側方向に照射して集魚する集魚方法において、前記光源からの光を漁船の前後方向の少なくとも一方にも照射し、かつ、この配光による漁船の周りの水中における明るいエリアの照度が漁船を中心とした水平の略長円状の線上の照射部でほぼ均一になるようにしたことを特徴とする。   In order to achieve the above object, the present invention provides a method for collecting fish by irradiating the sea surface in the vicinity of a fishing boat with a light source in the lateral direction of the fishing boat, and irradiating at least one of the light from the light source in the longitudinal direction of the fishing boat. And the illumination intensity of the bright area in the water around the fishing boat by this light distribution was made to become substantially uniform in the irradiation part on the horizontal substantially oval line centering on the fishing boat.

上記において、漁船下方の水中の照度が暗くなるように配光すればよい。   In the above, the light distribution may be performed so that the illuminance in the water below the fishing boat becomes dark.

また、本発明は、光源に前面ガラス付きの投光器を用いて上記の集魚方法を実施する照明方法である。   Moreover, this invention is an illumination method which implements said fish collection method using the light projector with a front glass for a light source.

また、本発明は、上記の集魚方法を実施するに際し、魚やイカが漁船付近に集まるに連れ、漁船付近に魚やイカを寄せ集めるように水中における照明の範囲及び光量を可変することを特徴とする照明方法である。   Further, the present invention is characterized in that, when the fish collection method described above is performed, the range of illumination and the amount of light in the water are varied so that the fish and squid gather near the fishing boat, and the fish and squid gather near the fishing boat. Illumination method.

また、本発明は、上記のいずれかを実施するための照明システムである。   Moreover, this invention is an illumination system for implementing either of the above.

また、本発明は、上記のいずれかを実施するための漁船である。   Moreover, this invention is a fishing boat for implementing either of the above.

本発明によれば、次の効果が得られる。
（１）魚やイカの誘引効果の向上
魚やイカが光に集まる性質を利用して、遠方又は深い場所にいる魚やイカ、又は魚やイカの餌となる小魚やプランクトンを漁船の針や網の届く範囲に誘引するが、その際に、漁船の前後方向の少なくとも一方にも光が照射されるように配光したので、漁船の従来よりも多くの方向から魚やイカを誘引することができる。
（２）水中への照明効果の向上
漁船の前後方向にも光が照射されるように配光したことで、漁船の前部や後部でも餌となる小魚、疑似餌などが、獲物（魚やイカ）に見えやすくなり、漁船前部及び後部での釣機の釣り上げ量を増加することが期待できる。
（３）水中での光バリア効果の向上
例えば、イカを漁獲するとき、集魚灯を用いて釣り上げられた場合でも、イカは暗順応状態であることが知られている。また、イカは光に集まる性質がある一方、余り強い光は嫌うことも知られている。このことから、従来の集魚灯において、集魚灯の光が漁船の左右では舷と平行に水中に入り込み、明るい部分ができ、光が届かない漁船下部では比較的暗い部分ができる。イカは夜、水深１００ｍ以上の深いところにいて、漁船の集魚灯に誘引され、漁船に近づき、かつ上昇するが、明順応するような強い光は好まないため、漁船の下部の比較的暗い部分に身を寄せる。この暗い部分から漁船の左右に逃げようとしても、そこは集魚灯で明るく照らされているため、イカは暗い漁船下部に留まらざるを得ない（光のバリア効果）。結果的に漁船下部にはイカの密度が高い領域ができる。そこに疑似餌を下ろせば、効率良くイカを釣り上げることができる。ところが、従来の集魚灯では、漁船の前後方向に十分な光が照射されていないため、折角、漁船下部の暗い部分に集まったイカが、漁船の前後方向の暗い方には容易に逃げてしまう。
この点、本発明では、集魚灯の光を漁船の前後方向の少なくとも一方にも照射し、漁船の従来よりも多くの方向に渡って周りの水中に効率良く、かつ広範囲に入射する強い光（誘引効果）とするとともに、漁船下部の水中にイカが好むような暗い領域を作り、その明部と暗部の境界にくっきりとした照度差ができるようにし、さらに、配光による水中の明部（光のバリア）が、漁船を中心とした水平の略長円状の線上の照射部でほぼ均一になるようにしたので、漁船下部に集まった魚やイカが逃げ難くなり、かつ前後方向からもイカを誘引することができ、集魚に効果的な配光が得られる。
（４）紫外線カット
紫外線カット機能を持つ前面ガラス付きの投光器を集魚灯をとして使うことで、甲板上で作業する乗組員が浴びる紫外線量を低減できる。
（５）魚やイカの行動及び行動範囲の制御による漁獲の増大
集魚灯による照明範囲及び光量を、魚やイカが集まってくるに連れて変化させることで、イカ等の行動を制御したり、水中の光のバリアで行動範囲を狭めたりすることが可能と考えられる。例えば、イカを遠方から誘引する段階では、集魚灯は、より遠くの海中を照らし、イカの群れが近づいてくるに連れ、漁船下部水中の暗部のエリアを狭めるように、より近くの海中を照らす。これにより、漁船下部のイカの密度がより高まるので、そのエリアから釣れるイカの量が増大することが期待できる。 According to the present invention, the following effects can be obtained.
(1) Improvement of attracting effect of fish and squid Using the property that fish and squid gather in the light, fish and squid in a distant or deep place, or small fish and plankton that feed fish and squid reach the reach of fishing boat needles and nets At that time, since the light is distributed so that light is also applied to at least one of the front and rear directions of the fishing boat, fish and squid can be attracted from more directions than in the conventional fishing boat.
(2) Improving the lighting effect in the water By distributing light so that light is also emitted in the front-rear direction of the fishing boat, small fish, simulated food, etc. that feed even at the front and rear of the fishing boat are prey (fish and It is easy to see squid), and it can be expected to increase the amount of fishing machine fishing at the front and rear of the fishing boat.
(3) Improvement of light barrier effect in water For example, when catching squid, it is known that squid is in a dark adaptation state even if it is caught using a fishing light. It is also known that squid has the property of gathering in light, but hates too much light. For this reason, in the conventional fishing light, the light from the fishing light enters the water in parallel with the coral on the left and right of the fishing boat, creating a bright part, and a relatively dark part at the lower part of the fishing boat where the light does not reach. The squid is at a depth of more than 100m at night and is attracted by the fishing light of the fishing boat, approaches the fishing boat and rises, but does not like the strong light that adapts to the light, so the relatively dark part of the lower part of the fishing boat Hang out. Even if you try to escape to the left and right of the fishing boat from this dark area, the squid must stay at the bottom of the dark fishing boat because it is brightly illuminated by the fishing light (light barrier effect). As a result, an area with high squid density is formed at the bottom of the fishing boat. If you put the pseudo food there, you can catch squid efficiently. However, with the conventional fishing light, sufficient light is not irradiated in the front-rear direction of the fishing boat, so the squid that gathers in the dark part at the bottom of the fishing boat easily escapes to the darker one in the front-rear direction of the fishing boat .
In this regard, in the present invention, the light from the fish collection lamp is also applied to at least one of the front and rear directions of the fishing boat, and the strong light (efficiently and widely incident on the surrounding water in many directions than the conventional fishing boat) In addition to creating a dark area that the squid prefers in the water under the fishing boat, a clear illuminance difference can be created at the boundary between the bright and dark areas. The light barrier was made to be almost uniform at the irradiation part on the horizontal, oval line centered on the fishing boat, making it difficult for the fish and squid gathering at the bottom of the fishing boat to escape, and from the front and back. Can be attracted, and an effective light distribution for collecting fish can be obtained.
(4) Ultraviolet ray cut Using a floodlight with a front glass with an ultraviolet ray cut function as a fishlight, it is possible to reduce the amount of ultraviolet rays exposed to crew members working on the deck.
(5) Increased fishing by controlling the behavior and range of fish and squid By changing the illumination range and light intensity of the fishing light as the fish and squid gather, control the behavior of squid and other It is considered possible to narrow the range of action with a light barrier. For example, at the stage of attracting squid from a distance, the fishing light illuminates the near sea as it illuminates the farther underwater and narrows the dark area under the fishing boat underwater as the squid flock approaches. . Thereby, since the density of the squid below a fishing boat increases more, it can be expected that the amount of squid that can be caught from the area increases.

以下、本発明による集魚方法と照明方法及びシステム並びに漁船の実施例について、図面を参照して説明する。   Embodiments of a fish collection method, an illumination method and system, and a fishing boat according to the present invention will be described below with reference to the drawings.

図１は、漁船の集魚灯にイカが集まるメカニズムを示している。漁船１に搭載された光源２（集魚灯ランプ）は、漁船１の周りの海面Ｓを照射する。比較的強い光で照射され明るいエリアＡ（斜線で示す）と、漁船１の下方の略錐体状の暗いエリアＢとを形成する。当初、イカ類１０は深い所に居て、光に誘われて上がって来るが、強い光を嫌って、漁船１の下にできた暗いエリアＢに集まり、そのエリアから出られなくなる。光源からの光は、カーテンのようになって水中に明暗の境界を形成し、イカにとってバリアとなる。   FIG. 1 shows the mechanism by which squid collects in the fishing light of a fishing boat. A light source 2 (fishlight lamp) mounted on the fishing boat 1 irradiates the sea surface S around the fishing boat 1. A bright area A (shown by diagonal lines) irradiated with relatively strong light and a substantially cone-shaped dark area B below the fishing boat 1 are formed. Initially, the squids 10 are in a deep place and are raised by light, but they hate strong light and gather in the dark area B under the fishing boat 1 so that they cannot leave the area. The light from the light source acts like a curtain, forms a light / dark boundary in the water, and becomes a barrier for squid.

図２は、本発明の実施例１による漁船１の光源（集魚灯ランプ）の配置構成を示している。集魚灯ランプ２０は、漁船１の甲板上適宜の高さ位置であって、舷の左右、及び前後（１ｆは船首、１ｅは船尾）に複数配置し、漁船１周りの水中の照度分布を均一に近づけた。すなわち、集魚灯ランプ２０からの光は、漁船１の前後方向及び左右方向に配光され、この配光により、漁船の周りの水中における明るいエリアの照度が漁船１を中心とした水平の略長円状の線上でほぼ均一になるようにし、また、漁船１下方の水中の照度は暗くなる。集魚灯ランプ２０としては、メタルハライドランプを用いる。集魚灯ランプ２０は、金属フレームに沿って渡されたワイヤ２ｗに吊るされている。ランプの安定器は、甲板下の収納室に収められる。   FIG. 2 shows an arrangement configuration of light sources (fish collection lamps) of the fishing boat 1 according to the first embodiment of the present invention. The fishing light lamps 20 are arranged at an appropriate height on the deck of the fishing boat 1 and are arranged on the left and right sides of the rod and on the front and rear (1f is the bow, 1e is the stern), and the illuminance distribution in the water around the fishing boat 1 is uniform. Approached. That is, the light from the fish lamp 20 is distributed in the front-rear direction and the left-right direction of the fishing boat 1, and this light distribution allows the illuminance of a bright area in the water around the fishing boat to be approximately horizontal in the horizontal direction around the fishing boat 1. It is made to become substantially uniform on the circular line, and the illuminance in the water below the fishing boat 1 becomes dark. A metal halide lamp is used as the fish collection lamp 20. The fish lamp 20 is hung on a wire 2w passed along a metal frame. The lamp ballast is housed in a storage room below the deck.

本実施例においては、集魚灯ランプ２０からの光を漁船１の左右方向だけでなく前後方向にも照射し、漁船１の全方向に渡って魚やイカを誘引できるとともに、漁船１下部の水中に暗い領域を作り、その明部と暗部の境界ができるようにしたので、漁船１下部に集まった魚やイカが逃げ難くなり、集魚効果が高まる。   In the present embodiment, the light from the fish collection lamp 20 is irradiated not only in the horizontal direction of the fishing boat 1 but also in the front-rear direction so that fish and squid can be attracted in all directions of the fishing boat 1 and Since the dark area is created and the boundary between the bright part and the dark part is made, it becomes difficult for the fish and squid gathered at the bottom of the fishing boat 1 to escape, and the fish collection effect is enhanced.

図３は、本発明の実施例２による漁船１の光源（集魚灯ランプ及び投光器）の配置構成を示している。この例では、漁船１の舷の左右に前記と同様の集魚灯ランプ２０を複数配置し、舷の前後に投光器２１を複数配置し、漁船１周りの水中の照度分布を均一に近づけた。投光器２１は、ステンレス又はアルミから成る器具本体が反射板を兼ねる構造とし、この反射板によって光の利用効率が高まる。また、反射板の前面にはガラス板があり、紫外線を吸収し、これにより、作業者の日焼け防止になる。投光器２１の光源としてはメタルハライドランプを用いていて、安定器は集魚灯ランプ２０の安定器と共に甲板下の収納室に収められる。   FIG. 3 shows the arrangement of the light sources (fish collection lamps and projectors) of the fishing boat 1 according to the second embodiment of the present invention. In this example, a plurality of fish collecting lamps 20 similar to the above are arranged on the left and right of the fishing boat 1, and a plurality of floodlights 21 are arranged on the front and rear of the fishing boat 1 to make the illuminance distribution around the fishing boat 1 uniform. The projector 21 has a structure in which an instrument body made of stainless steel or aluminum also serves as a reflector, and the light utilization efficiency is increased by this reflector. In addition, there is a glass plate in front of the reflecting plate, which absorbs ultraviolet rays, thereby preventing the operator from sunburn. A metal halide lamp is used as the light source of the projector 21, and the ballast is housed in a storage room below the deck together with the ballast of the fish lamp 20.

図４は、本発明の実施例３による漁船１の光源（集魚灯ランプ及び投光器）の配置構成を示している。この例では、前記実施例２において、舷の前後に配置される投光器２１を低い高さ位置に設けた。この種の投光器は重いことから、低い位置に設けることで、船の安定性を向上した。   FIG. 4 shows the arrangement of the light sources (fishlight lamps and projectors) of the fishing boat 1 according to the third embodiment of the present invention. In this example, in Example 2, the projectors 21 arranged before and after the ridges were provided at a low height position. Since this type of floodlight is heavy, the stability of the ship was improved by installing it at a low position.

図５は、本発明の実施例４による漁船１の光源（投光器又は灯具）の配置構成を示している。この例は、前記実施例１における集魚灯ランプ２０に代えて、反射板付きの灯具又は投光器２１を用いたものである。漁船１の前後にもランプを配置したことで、水中の配光を均一にすることができ、前記実施例と同様の効果が得られる。   FIG. 5 shows an arrangement configuration of light sources (projectors or lamps) of the fishing boat 1 according to the fourth embodiment of the present invention. In this example, instead of the fish collection lamp 20 in the first embodiment, a lamp with a reflector or a projector 21 is used. By arranging the lamps before and after the fishing boat 1, the light distribution in the water can be made uniform, and the same effect as in the above embodiment can be obtained.

図６は、本発明の実施例５による漁船１の光源（投光器）の配置構成を示している。この例は、前記実施例４と同等の投光器２１を用い、船の舷に光の遮蔽物３を設けた。投光器２１と遮蔽物３による光照射エリアＡに対応するところは明部となる（図示では右舷、前部にのみ光照射エリアＡを示しているが、左舷、後部にも同様のエリアがある）。これにより、水中の明部と暗部の境界の照度差が大きくなる。また、この遮蔽物３を可動として、明部と暗部の境界を移動制御できるようにしてもよい。   FIG. 6 shows an arrangement configuration of light sources (projectors) of the fishing boat 1 according to Embodiment 5 of the present invention. In this example, a light projector 21 equivalent to that in Example 4 was used, and a light shield 3 was provided at the foot of a ship. The portion corresponding to the light irradiation area A by the projector 21 and the shield 3 is a bright portion (in the drawing, the light irradiation area A is shown only on the starboard and front, but there is a similar area on the port and rear). . Thereby, the illuminance difference at the boundary between the bright part and the dark part in water increases. Further, the shield 3 may be movable so that the movement between the bright part and the dark part can be controlled.

図７は、本発明の実施例６による漁船１の光源（投光器）の配置構成を示している。この例では、５０Ｗ程度のショートアークＨＩＤランプをプロジェクタ型の灯具に入れた小型の投光器２３を用い、これを船の舷に取り付けた。投光器は、水中の配光を均一にするために、漁船の前後に重点的に配置している。この投光器２３によれば、シャープな配光が得られ、暗部と明部の境界を際立たせることができる。   FIG. 7 shows an arrangement configuration of light sources (projectors) of the fishing boat 1 according to Embodiment 6 of the present invention. In this example, a small floodlight 23 in which a short arc HID lamp of about 50 W was put in a projector-type lamp was used, and this was attached to the ship's anchor. The floodlights are placed preferentially before and after the fishing boat to make the light distribution in the water uniform. According to the projector 23, a sharp light distribution can be obtained, and the boundary between the dark part and the bright part can be made to stand out.

図８乃至図１２は、本発明の実施例７乃至１１による漁船１での集魚の照明方法を示している。これらの実施例は、いずれも漁船付近に魚やイカを寄せ集めるように水中における照明の範囲又は光量を可変するものである。   8 to 12 show a method for illuminating a fish collection on a fishing boat 1 according to Embodiments 7 to 11 of the present invention. In each of these embodiments, the range of illumination or the amount of light in water is variable so that fish and squid are gathered near the fishing boat.

図８は、実施例７を示す。この実施例は、漁船１の支柱４に設けられた投光器２１の向きを可変とされ、照射方向を変えることができる。最初は、同図（ａ）に示すように、漁船１から遠くを投光器２１により照射して（エリアＡ１）、広範囲の魚やイカ類１０を漁船付近におびき寄せる。イカは強い光を嫌うので、漁船１付近の暗い部分に入り込む。この時の水面での光の届く範囲は、同図（ｃ）の斜線Ｂ１となり、漁船１を中心とした大きい略長円状となる。イカ類１０が漁船１付近に集まってきたら、同図（ｂ）に示すように、投光器２１の向きを変えて照射方向を変える（エリアＡ２）。この時の光の届く範囲は、同図（ｄ）の斜線Ｂ２となり、漁船１を中心とした小さい略長円状となる。これにより、イカ類１０を釣り上げ易い漁船１の底部の暗部に追い込み閉じ込めることができる。漁船１の底には超音波により物体を検知するソナー７が設けられている。   FIG. 8 shows a seventh embodiment. In this embodiment, the direction of the projector 21 provided on the support 4 of the fishing boat 1 is variable, and the irradiation direction can be changed. At first, as shown in FIG. 5A, the projector 21 irradiates the area far from the fishing boat 1 (area A1) and draws a wide range of fish and squids 10 near the fishing boat. Squids hate strong light, so they go into the dark area near fishing boat 1. At this time, the reach of light on the water surface is a slanted line B1 in FIG. When the squids 10 gather near the fishing boat 1, the direction of the projector 21 is changed and the irradiation direction is changed (area A2) as shown in FIG. The range where the light reaches at this time is a slanted line B2 in FIG. Thereby, the squid 10 can be driven and confined in the dark part of the bottom part of the fishing boat 1 which is easy to catch. A sonar 7 for detecting an object by ultrasonic waves is provided at the bottom of the fishing boat 1.

図９は、実施例８を示す。この実施例は、漁船１の支柱４に設けられた投光器２１の位置を可変とされ、照射範囲を変えることができる。投光器２１は支柱４に伸縮可能な筒５に取り付けられている。これにより、最初は、同図（ａ）に示すように、投光器２１は高い位置から遠くを照射し（エリアＡ１）、これにより、イカ類１０が漁船１付近に集まってきたら、同図（ｂ）に示すように、投光器２１は低い位置から近くを照射する（エリアＡ２）。このような照明制御によっても上記と同等の作用が得られる。   FIG. 9 shows an eighth embodiment. In this embodiment, the position of the projector 21 provided on the support 4 of the fishing boat 1 is variable, and the irradiation range can be changed. The projector 21 is attached to the cylinder 5 that can be extended and contracted to the column 4. Thereby, as shown to the figure (a) at first, the light projector 21 irradiates far from a high position (area A1), and when squids 10 gather near the fishing boat 1 by this, (b) ), The projector 21 irradiates near from a low position (area A2). The same operation as described above can be obtained by such illumination control.

図１０は、実施例９を示す。この実施例では、漁船１の支柱４の高い位置と低い位置とにそれぞれ遠距離照射用と近距離照射用の２灯の投光器２１，２２が設けられ、照射距離を変えることができる。これにより、最初は、同図（ａ）に示すように、投光器２１をオンして遠くを照射し（エリアＡ１）、その後、同図（ｂ）に示すように、投光器２２をオンして近くを照射する（エリアＡ２）。このような照明制御によっても上記と同等の作用が得られる。   FIG. 10 shows a ninth embodiment. In this embodiment, two light projectors 21 and 22 for long-distance irradiation and short-distance irradiation are provided at the high and low positions of the support 4 of the fishing boat 1, respectively, and the irradiation distance can be changed. As a result, first, as shown in FIG. 9A, the projector 21 is turned on to irradiate a distance (area A1), and then, as shown in FIG. (Area A2). The same operation as described above can be obtained by such illumination control.

図１１は、実施例１０を示す。この実施例では、投光器２１は、同図（ｅ）（ｆ）に示されるように、ランプ２１ａと略放物面反射鏡２１ｂとから成り、ランプ２１ａを略放物面反射鏡２１ｂの焦点２１ｃに対して前後移動可能とされ、ランプ２１ａの移動により照射範囲を可変とされている。最初は、同図（ａ）（ｅ）に示すように、投光器２１のランプ２１ａを焦点２１ｃからずらせて、広い照射範囲を照らす（エリアＡ１）。その時、照射範囲は同図（ｃ）の斜線Ｂ１となる。その後、同図（ｂ）（ｆ）に示すように、投光器２１のランプ２１ａを焦点２１ｃに一致させ、狭角の強度の高い光を照射する（エリアＡ２）。その時、照射範囲は同図（ｄ）の斜線Ｂ２となる。このような照明制御によっても上記と同等の作用が得られる。   FIG. 11 shows a tenth embodiment. In this embodiment, the projector 21 includes a lamp 21a and a substantially parabolic reflecting mirror 21b, as shown in FIGS. 5E and 5F, and the lamp 21a is made a focal point 21c of the substantially parabolic reflecting mirror 21b. The irradiation range can be changed by moving the lamp 21a. At first, as shown in FIGS. 4A and 4E, the lamp 21a of the projector 21 is shifted from the focal point 21c to illuminate a wide irradiation range (area A1). At that time, the irradiation range is the oblique line B1 in FIG. Thereafter, as shown in FIGS. 5B and 5F, the lamp 21a of the projector 21 is made to coincide with the focal point 21c, and light with high intensity at a narrow angle is irradiated (area A2). At that time, the irradiation range is the oblique line B2 in FIG. The same operation as described above can be obtained by such illumination control.

図１２は、実施例１１を示す。この実施例では、投光器２１は、同図（ｃ）に示されるように、ランプ前面一部を遮る状態と遮らない状態とを取り得る遮蔽板２１ｄを有したものを用い、遮蔽板２１ｄの移動で照射範囲を可変としている。最初は、同図（ａ）に示すように、遮蔽板２１ｄにより投光器２１の前面を遮っていない状態で、広い範囲を照射する（エリアＡ１）。その後、同図（ｂ）に示すように、遮蔽板２１ｄにより投光器２１の前面一部を遮る状態とし、エッジの鋭い配光を作り、かつ、照射方向を変える（エリアＡ２）。このような照明制御によっても上記実施例１０と同等の作用が得られる。   FIG. 12 shows Example 11. In this embodiment, as shown in FIG. 5C, the projector 21 has a shielding plate 21d that can take a state of blocking or not blocking a part of the front surface of the lamp, and the movement of the shielding plate 21d. The irradiation range is variable. At first, as shown in FIG. 5A, a wide area is irradiated in a state where the front surface of the projector 21 is not blocked by the shielding plate 21d (area A1). After that, as shown in FIG. 5B, a part of the front surface of the projector 21 is blocked by the shielding plate 21d, a light distribution with a sharp edge is made, and the irradiation direction is changed (area A2). Such illumination control can provide the same effect as that of the tenth embodiment.

以上、実施例について説明したが、具体的な構成は、これらの実施例に限られるものではなく、例えば、漁船の前後方向への光の照射については少なくともその一方へ照射するば良いなど、本発明の要旨を逸脱しない範囲の設計変更などがあっても、本発明に含まれる。   Although the embodiments have been described above, the specific configuration is not limited to these embodiments. For example, it is sufficient to irradiate at least one of the light irradiation in the front-rear direction of the fishing boat. Even if there is a design change in a range not departing from the gist of the invention, it is included in the present invention.
