PROBLEM TO BE SOLVED: To provide a squid hook that can hook only squids and prevent other fishes from snapping, in which hooks are fastened at the rear of clear plastic, bamboo and lead rods and squids are hooked in a conventional squid hook, however, the hooking of other fishes such as mackerels cannot be avoided in a blanco fishing tackle often used in a share-ride boat, and it takes a great time to remove the hooks particularly when swallowed, and also the fishing tackle has to be lifted up once from a considerable depth for removal and processed even when hooked just in a mouth.SOLUTION: A structure of the present invention achieving above purpose is configured such that a fish hooking prevention device in the shape of tail and fins of fish is applied at the rear side of a hook existing in a normal squid hook tail. The article resembles the tail of the fish but is hard, so that it is hooked to an upper jaw, a lower jaw, and a cheek, etc., in the mouth of the fish, and is discharged due to a sense of incongruity. The embracing and eating by the squid are not affected because of the same shape of the tail of the fish, and thereby only the snapping of the fish can be prevented by the structure.COPYRIGHT: (C)2015,JPO&INPIT【課題】 従来のイカ角は透明プラスチックや竹棒、鉛棒の後部に針を縛り付けイカを釣る。しかし、乗合船でよく使われるブランコ仕掛けでは、鯖など他の魚が食って来るのを除ける事ができない。特に飲み込まれた場合は外すのに大変な時間を要する。口に掛かっただけでも外す為に相当の深さから仕掛けを一度上げて処理しなければならない。イカのみ釣れて魚は食いつけないイカ角を提供する。【解決手段】 上述の目的を達成する本発明の構造は、通常のイカ角最後部に有る針の後ろ側に、魚の尾鰭状の魚掛かり防止装置を施す。その物は魚の尻尾に似ているが硬い為、魚の口の中、上あご、下あご、頬などに引っ掛かり違和感の為吐き出してしまう。イカの抱き付き、食いには魚の尻尾と同じ為、影響を与えず、魚のみを食いつき防止する構造としたものである。【選択図】図1
