Вплив кратності годівлі на результати вирощування мальків стерляді в басейнах

Abstract

Growing young sturgeons in pools to sustainable stages is one of the most difficult tasks and the choice of technological aspects of feeding is very important. In this regard, issues related to the regime of feeding young people when growing in swimming pools are important. In this regard, the search for the optimal feeding rate of sterlet fry in swimming pools and became the main goal of the experiment. The analysis of the influence of feeding frequency on the efficiency of growing sterlet fry allowed to note that bringing the relative volume of the daily diet when feeding young to 40 - 50% of body weight by increasing feeding frequency to ten times a day has a positive effect on growth rate, survival and efficiency use of feed for growth. The average weight of fry increases by 5.57 - 8.01%, fish productivity - by 18 - 24%.
