本発明は、以下の(1)ないし(5)の養魚用飼料を要旨とする。
(1)最大反射波長が藍色から青色系の波長成分であり、L*a*b*表色系においてb*がマイナス側(−b*)にある青色系より選ばれる、魚食性の養殖魚に対して摂餌を誘引する色を有する養魚用飼料。
(2)飼料表面の10%以上が上記の摂餌を誘引する色である上記の(1)の養魚用飼料。
(3)飼料表面の10%以上をL*a*b*表色系においてb*がマイナス側(−b*)になるよう色素を配合した、あるいは色素で着色した上記の(1)または(2)の養魚用飼料。
(4)飼料表面の10%以上をL*a*b*表色系においてb*がマイナス側(−b*)になるよう青色系の色を呈した可食性ケーシングに封入した上記の(1)または(2)の養魚用飼料。
(5)飼料表面の10%以上をL*a*b*表色系においてb*がマイナス側(−b*)になるよう原料配合をした上記の(1)または(2)2の養魚用飼料。
