  • Publication number: 20050175673
    Abstract: The invention relates to feedstuff for aquatic animals, which contains at least two feed mixes of different composition in single-piece units and which is characterized in that the single-piece units comprise at least two contiguous and merging zones that contain the feed mixes separately from each other. Most preferably, the feedstuff consists of bi- or multicolored feedstuff flakes that contain different feed mixes or drugs in individual separate zones.
