FIELD: fodder production, pisciculture. SUBSTANCE: the present innovation deals with manufacturing feedstuffs for fishes at their increased adhesive properties. One should introduce a powder-like composition containing, weight%: high-molecular chitosan 50.0-60.0, glutamic acid 25.0-35.0, methionine 10.0-25.0 into feed mixer as a binding component. This composition is introduced at the quantity of 0.05-0.5 weight% chitosan against total feedstuff weight. The method enables to improve feedstuffs quality due to increasing their strength and water-resistance at simultaneous improving piscicultural-biological values, and, also, enables to increase technological effectiveness and safety at their manufacturing. EFFECT: higher efficiency. 5 ex, 9 tbl
