本発明は、船腹に釣機を備えた漁船で、漁船の
周囲の海面を高照度で照明して、イカ釣漁を行な
うイカ釣漁法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a squid fishing method in which a fishing boat equipped with a fishing machine is used to catch squid by illuminating the sea surface around the fishing boat with high illuminance.
従来のイカ釣漁法は、第１図を用いて説明する
と、イカ釣漁の船腹２に釣機３を設け、マストや
ロープ等に取り付けた照明具４ａ，４ｂ，４ｃ
で、主に船腹の周囲の海面を高照度で照明して、
イカ釣作業を行つている。この場合、照度の強さ
は、曲線Ａで示すように、船腹に面した第１の海
面区域が一番大きく、船首５や船尾６に寄つた第
２の海面区域は比較的小さい。 The conventional squid fishing method will be explained using FIG. 1. A fishing machine 3 is installed on the side of a squid fishing boat 2, and lighting equipment 4a, 4b, 4c is attached to a mast, rope, etc.
The sea surface around the ship's belly is illuminated with high intensity,
I am engaged in squid fishing. In this case, as shown by curve A, the intensity of illumination is greatest in the first sea surface area facing the belly of the ship, and is relatively small in the second sea surface areas near the bow 5 and stern 6.
ところで、最近、上記照明は、明るい方が良い
と言うことで照明具としてハロゲン白熱電球や放
電灯を内蔵したものが利用され、かなり漁獲効率
を向上させることに成功したものの、時々漁獲効
率が、著しく落ちる場合があることが分つた。 By the way, recently, the brighter the better, so those with built-in halogen incandescent bulbs or discharge lamps have been used as lighting equipment, and although they have succeeded in significantly improving fishing efficiency, sometimes the fishing efficiency is It has been found that there may be a significant drop.
上記現象を詳しく調べたところ、
イ） 明るいとイカは良く集まること、たゞし、
明る過ぎると、イカは集まるだけで、食餌活動
が小さいこと、
ロ） 明るさを適当に抑制すると、イカの集まり
はやゝ劣るが、食餌活動が大きくなること、
つまり、イカを集める明るさと、食餌活動の明る
さとを使い分けるのが良いことが分つた。 After investigating the above phenomenon in detail, we found that: a) Squid gather more easily when it is bright;
If the brightness is too bright, the squid will only gather, but their feeding activity will be small; (b) If the brightness is appropriately suppressed, the squid will gather less, but their feeding activity will increase; It turns out that it is good to use the brightness of feeding activity.
本発明の目的は、漁獲効率の良い新しいイカ釣
漁法を提供することにある、その特徴とするとこ

域の照度を、第１の海面区域に隣接する第２の海
面区域の照度より低くして、イカ釣漁を行なうこ
とにある。 The purpose of the present invention is to provide a new squid fishing method with high catch efficiency.The characteristics of this method are as follows: A fishing boat is equipped with a fishing machine on the hull, and the sea surface around the fishing boat is illuminated with high intensity. When squid fishing, the illuminance of the first sea surface area facing the belly area of the ship where the fishing machine is installed is lower than the illuminance of the second sea surface area adjacent to the first sea surface area, The purpose is to go squid fishing.
以下第２図を用いて、本発明イカ釣漁法を説明
すると、例えば、一番船首に近い照明具４ａと一
番船尾に近い照明具４ｂとの照射方向を夫々船首
側、船尾側に向け、かつ大きな照度で第２の海面
区域を照明し、中央部の照明具４ｃは照度を低く
して船腹に面する第１の海面区域を照明し、漁船
の周囲の海面の明るさを、曲線Ｂで示すようにす
る。 The squid fishing method of the present invention will be explained below with reference to FIG. 2. For example, the illumination direction of the lighting device 4a closest to the bow and the lighting device 4b closest to the stern are directed toward the bow side and the stern side, respectively. The illumination device 4c in the center illuminates the first sea surface area facing the ship's belly with low illuminance, and the brightness of the sea surface around the fishing boat is determined by curve B. Do as shown in .
上記照明法によると、イカは、船首側、船尾側
を中心にして非常に良く集まり、この集められた
イカが船腹側に移動して良く食餌活動をするので
漁獲効率が著しく向上する。 According to the above-mentioned lighting method, squid gather very well around the bow and stern sides of the ship, and the gathered squid move to the side of the ship and feed well, resulting in a marked improvement in fishing efficiency.
本発明は上記の通り、釣機の設けられた船腹に
面した第１の海面区域は、イカの食餌活動のしや
すい明るさに、むしろ抑制し、それに隣接する船
首側または船尾側の第２の海面区域を大きな照度
で照明して、イカを長く集めるようにしているの
で、著しく漁獲効率を向上せしめる利益を有す
る。 As described above, the present invention is such that the first sea surface area facing the belly of the ship where the fishing machine is installed is rather suppressed to a level of brightness that is conducive to feeding activities of squid, and the second sea surface area adjacent to it on the bow side or the stern side Since the sea surface area is illuminated with high illuminance to attract squid for a long time, it has the benefit of significantly improving fishing efficiency.
