FEED FOR ANADROMOUS FISH, METHOD FOR PRODUCING IT, METHOD OF INCREASING SEAWATER TOLERANCE, GROWTH AND FEED INTAKE OF ANADROMOUS FISH, FISH FEED FOR USE IN PREVENTING OR REDUCING SEVERITY OF CATARACTS
A fish feed for feeding to anadromous fish in freshwater comprises arginine in free amino acid form or dipeptide form, 0.1 to 7 wt% histidine in free amino acid form or dipeptide form, and 0.2-5 wt% Na+. The fish feed may be fed to anadromous fish to promote growth in the freshwater and/or seawater phase, to promote feed intake and/or to prevent or reduce severity of cataracts.
A nutrimental complement suitable for ingestion by larvae of shrimp or fish is disclosed. The nutrimental complement comprises a particulate gel structure comprising agar, an attractant and water; and an aqueous medium comprising at least one salt. The particulate gel structure may be formed into gelled particles, e.g., granules, and the gelled particles may be added to the aqueous medium. The invention also relates to a method of preparing the nutrimental complement and a method of co-feeding the nutrimental complement to shrimp larvae or fish larvae with at least one wet or dry feed, e.g., a complete wet or dry feed.
A23K 10/30 - Animal feeding-stuffs from material of plant origin, e.g. roots, seeds or hayAnimal feeding-stuffs from material of fungal origin, e.g. mushrooms
A23K 40/00 - Shaping or working-up of animal feeding-stuffs
A23K 50/80 - Feeding-stuffs specially adapted for particular animals for aquatic animals, e.g. fish, crustaceans or molluscs
The invention relates to the field of aquaculture feed compositions and to the field of feeding and farming of aquatic organisms including fish, such as seabream and crusta-ceans, so as shrimp. Provided is an aquaculture feed composition in the form of pellets having specific dimensions and comprising high wt.% of protein and comprising a source of charcoal. Results show the aquaculture feed compositions having different benefits over prior art aquaculture feed compositions.
