魚の摂餌行動に及ぼす背景色の影響をみることを目的とした水槽行動実験を行った。供試魚にはスズキを用い, 白, 赤, 緑, 青を背景色として擬餌5種類(白, 赤, 緑, 青および透明)を同時に投入し, 擬餌に対する魚の行動記録を水中ビデオカメラで撮影記録し, 解析した。背景が白では, 緑の擬餌に対する食付き頻度が顕著に高かった。また, 背景が赤および青では, 透明および白の擬餌に高い食付き頻度を示した。高頻度で選択される擬餌の色は背景色によって異なり, 背景色とルアー色の普遍的な組み合わせは見出せなかった。Influence of background color in color choice of the Japanese sea bass was studied in an experimental tank. White, red, green and blue were used for the background color of the tank, and five colors of lure (white, red, green, blue and transparent) were thrown into the tank and the response behavior to the lures by the fish was videotaped and analyzed. The fish exhibited the highest bite frequency on the green lure in the white background, and the white and transparent lures in the red and blue backgrounds. Thus, the fish chose the most visible lures in the respective background color. The highly frequent bites to the transparent lure were probably attributed to the hue feeding history of the animal which is related to the past experience of eating transparent fish and crustacean larvae.
