Fine granular feeds for fry of fishes and shellfishes capable of remarkably elevating the survival rate of fry, improving the cultivation efficiency, and causing little elution of nitrogen sources therefrom into seawater or water in feeding, which are characterized by containing at least two active components, i.e., (a) a long-chain unsaturated fatty acid calcium salt blend comprising 80 % by weight or more of long-chain unsaturated fatty acid calcium salt(s) having at least 18 carbon atoms and 20 % by weight or less of a browned matter formed by heating molasses or saccharides, a browned matter formed by heating saccharides with amino acids or a mixture thereof at an arbitrary ratio, and (b) a mixture of peptides obtained by hydrolyzing animal protein, and being in the form of fine grains.

L'invention concerne une nourriture en grains fins pour alevins capable d'augmenter considérablement le taux de survie des alevins, d'augmenter l'efficacité d'une pisciculture et d'entraîner une faible élution des sources azotées de la nourriture dans l'eau de mer ou dans l'eau douce lors de l'alimentation. Cette nourriture se caractérise par le fait qu'elle contient au moins deux composants actifs, à savoir (a) un mélange de sel de calcium à acides gras insaturés à longue chaîne renfermant au moins 80 % en poids de sel(s) de calcium à acides gras insaturés à longue chaîne comprenant au moins 18 atomes de carbone, et au maximum 20 % en poids d'une matière brunie formée par chauffage de mélasses ou de saccharides, d'une matière brunie formée par chauffage de saccharides avec des acides aminés, ou d'un de leurs mélanges selon un rapport arbitraire, et (b) un mélange de peptides obtenus par hydrolyse de protéines animales. Cette nourriture se présente sous la forme de grains fins.
