A feed for farming tuna species includes a body portion flattened with a length in a thickness direction orthogonal to a width direction and to a longitudinal direction, being shorter than a length in the width direction orthogonal to the longitudinal direction. The feed satisfies (A) and/or (B): (A) when a maximum length in the longitudinal direction is defined as a (mm), a maximum length in the width direction is defined as b (mm), and a maximum length in the thickness direction is defined as c (mm), a flattening ratio f1 calculated by Formula (1) is about 110 or greater: f1=a×b/c (1); and (B) when a volume of the feed for fish farming is defined as V (cm3), and an area of the feed for fish farming in a plan view is defined as A (mm2), (V/A)1/2 is about 0.110 or less.
A feed for farming tuna species, the feed comprising a body portion that is flattened with a length in a thickness direction orthogonal to a width direction and to a longitudinal direction being shorter than a length in the width direction orthogonal to the longitudinal direction, and the feed satisfying at least one selected from the group consisting of (A) and (B) as defined below:
A feed for farming tuna species, having a settling velocity from a depth of 15.0 cm to a depth of 35.2 cm with a water surface as a reference of less than or equal to about 15.0 cm/s.
A feed group for fish farming, comprising a plurality of feeds for farming tuna species, and having an average settling velocity from a depth of 15.0 cm to a depth of 35.2 cm with a water surface as a reference of less than or equal to about 15.5 cm/s.
A method for producing a feed for farming tuna species, the method comprising a step of pressing and deforming, in a radial direction, a molded product including a body portion having a substantially cylindrical shape to deform the body portion into a shape with a radial cross-section of the molded product being flattened.
