PROBLEM TO BE SOLVED: To provide a system for informing a user of a fish notice that a user can easily use. A detection signal acquisition unit that acquires a detection signal output by a sensor provided to detect a vibration generated in at least one of detection objects of a fishing reel 300 and a fishing rod 400, and a user. In addition, the fish-notice alerting device 100 is configured by including a vibration generation unit that generates vibration and a vibration instruction unit that outputs a vibration instruction signal for generating vibration based on the detection signal acquired by the detection signal acquisition unit. To do. [Selection diagram] Figure 2【課題】ユーザが個人で手軽に利用できる魚信を報知するシステムを提供する。【解決手段】魚釣用リール３００と釣竿４００との少なくとも一方の検出対象物にて生じた振動を検出するように設けられるセンサが出力する検出信号を取得する検出信号取得部と、ユーザが身に付け、振動を発生する振動発生部に、検出信号取得部により取得された検出信号に基づき振動を発生させるための振動指示信号を出力する振動指示部とを備えて魚信報知装置１００を構成する。【選択図】図２
