Abstract: Provided is an aquacultured crustacean having improved umami, uses thereof, and a method for producing the same. The crustacean does not burrow in sand, contain glycine and alanine, and has 2400 mg or more of free amino acids per 100 g of abdominal muscle. The content of glycine is 550 mg or more per 100 g of abdominal muscle, and the content of alanine is 140 mg or more per 100 g of abdominal muscle.

Abstract: 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.

Abstract: [Problem] To provide 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. [Solution] A feed for fish farming consisting of 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%. A feed for fish farming characterized by consisting of 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. As the protein, surimi, ground fish meat, krill, gelatin, collagen, gluten, egg albumen and soy bean protein are preferred. As the starch, tapioca starch, wheat starch, potato starch, corn starch, bean starch, waxy corn starch and processed products of these starches are preferred.
