PROBLEM TO BE SOLVED: To provide a formula feed equally or more improved in feed intake in cultured fishes, in particular, ichthyophagous fishes to or than raw feed. SOLUTION: This fish culture feed has a color selected from the groups comprising blue colors and white colors, and inducing feed intake in ichthyophagous fishes. Ten % or more of the surface of the feed has the feed intake-inducing color. The blue colors have high reflectance of the light in wavelengths ranging from indigo blue to blue, specifically b* in an L*a*b* color system is minus side (-b*). The white colors have high brightness at the surface of the feed, specifically L* in the L*a*b* color system is ≥60. The fish culture feed is such one as to be enclosed in an edible casing, or the like, formulated or colored with a dye so that 10% or more of the surface of the feed has -b* in the L*a*b* color system, and has ≥60 of L*, or is obtained by so formulating raw materials with the dye.
