For the first time in Kazakhstan, composition of starter feeds for larval and young zanders have been developed and is based on domestic feeds. The
feed has been produced by extrusion. Properties of the feed and its nutritional value have been studied. Protein content is 57.5%, fat is 12.2%, total energy value is 494.58//20.60 kcal per 100//MJ, digestible energy is 415.4/17.3 kcal per 100//MJ. Production tests have been conducted in order to see the effectiveness of the use of the feed and its uptake by zander youngs at the Halyk Balyk LLP facility. Aller Agua, food for trout, served as a reference. Research and business experiment showed the specific feed conversion efficiency of 1.3, which is slightly inferior to imported feed examples, with the survival rate at 51%, average daily increase at 2.9 mg. According to the recipes designed, starter feed production will help solve
the problem of import substitution.
Key words: starter feed composition, physical and chemical properties, extrusion, fich preeding, pike perch preeding.
