Efficiency of the use of Manana Fish food in the diets of sturgeon juvenile

The paper presents data on the study of the effect of complete mixed feeds used on the farm and the trademark Manana Fish on zootechnical indicators. These studies were carried out for 60 days in the conditions of pools in the farm of the Leningrad region of the Krasnodar Territory on sturgeon fry. The aim of the work was to determine the effect of the Manana Fish food STURGEON Y 50/18 on the growth rate and development of sturgeon juvenile. The inclusion of 10% of live food in the basal diet of the farm contributed to an increase in gross weight gain of fish by 3.7% compared to the control group. The gross weight gain of fish in the third, fourth and fifth groups exceeded the control values by 25.0%, 15.7% and 34.3%, respectively. Feeding the studied compound feed in the experimental groups had a positive effect on the coefficient of fatness, which in the third group was equal to 2.59, which is 5.2% more than the control; in the fourth group - 2.5, which exceeds the indicator of the first group by 1.6%. In the fifth group, the highest indicator was observed - 2.76 relative to the control group. The highest level of profitability was noted in the third group (41.31%), the fish in which received 100% of the Manana Fish feed and in the fifth group (46.89%), the fish in which also received 90% of the Manana Fish feed plus 10% live food. The fourth group was more profitable and exceeded the control indicator by 16.16%. The inclusion of 10% live feed in the basal diet of the farm contributed to an increase in the level of profitability by 3.85%, compared to the first group without additives.
