This invention provides a feed for fish farming which is excellent in terms of stability of feed supply and feed shelf life and which has excellent feed intake and feed efficiency.;The feed for fish farming has an outer layer and an inner layer, characterized in that a composition constituting the outer layer has a breaking stress of 5×104 to 1×106 N/m2, a cohesiveness (30%) of 0.4 to 1.0, and a breaking strain of 30 to 80%. The feed for fish farming is characterized by having an outer layer constructed from a heat-induced gel which comprises a protein and/or a starch, and an inner layer comprising a composition which contains nutrient ingredients having fish meal and an oil as essential ingredients.
