Abstract: 遊漁対象種の希少性や生物学的特性の違いに着目し,北海道然別湖,朱鞠内湖および洞爺湖における遊漁者を対象に,遊漁者の満足度と釣果の関係を比較した。その結果,1)希少魚の釣果は1尾の釣果が遊漁者の満足度を大きく高める,2)希少魚の釣果はその魚種が1番の狙いの魚種でなくとも遊漁者の満足度に影響を与えうる,3)大型に育つ遊漁対象種では釣獲尾数よりも体サイズに満足度の主眼がおかれる,4)遊漁対象種に食用としての価値が高い場合,遊漁者にとって満足といえる釣獲尾数はより多くなる,という傾向が明らかになった。
Recreational angling is a dominant use of inland fish resources. Since recreational angling is a leisure-based activity, the stock manager must meet two objectives: 1) maintain fish stocks, and 2) maximize angler satisfaction with limited catch. To achieve these goals, it is important to evaluate the relationship between angler satisfaction and catch in order to construct a management strategy, because catch is one of the most important connections between fish stock and angler satisfaction. In this study, the relationships of four angling target species which have different biological and social traits were investigated. The results of a questionnaire survey of 639 anglers in total revealed four types of orientation: 1) the catch of endemic target fish strongly enhances angler satisfaction, 2) the existence of endemic fish increases angler satisfaction for all anglers, 3) fish size has a greater influence than number of fish for anglers who target fish that grow larger (i.e. trophy anglers), and 4) anglers desire more fish when the target fish has higher value as a food (i.e. consumption orientation). For the sustainable use of fish stocks for recreational angling, not only the biological traits of stocks but also anglers' orientation toward catch should be considered.
