DEVELOPMENT OF PRODUCTION TECHNOLOGY FOR EXTRUDED STARTER COMPOUND FEEDSFOR JUVENILE FISH

Abstract

The article presents the results of developing recipes for domestic extruded starter compound feeds for zander, tilapia and Clary catfish. Technological modes of their production, as well as physical-chemical, mechanical and technological indicators of the developed compound feeds are established. The developed compound feeds are well-loose grains of dark and light brown colors, with sizes from 0,2 to 2,0 mm. Indicators of water resistance were at least 2,5 hours, crumbling no more than 1,5 %, swelling of granules 10-15 minutes, volume mass below 1000 kg/m3. The data obtained show that the developed feed meets the regulatory requirements for starting fish feeds. The introduction of the developed technology for the production of starter compound feeds at domestic enterprises of the feed industry will reduce the dependence of industrial fish farms on the import of compound feeds and thereby increase the profitability of the industry.
