Abstract
The paper presents the results of the experiment in juvenile rainbow trout (Oncorhynchus mykiss) weighing 60 g., conducted on the basis of the fish hatchery enterprise LLC Raduzhny in the Kabardino-Balkarian Republic. The fish were raised in pools (30×4×1,5 m) with running water supply, 30 l/sec. The probiotic “Bacifolin A” was added to the experimental group at the rate of 1 g per kg of feed. At all stages of the study, the superiority of the juveniles in the experimental group in weight by 7,3-10,3% was established. At the end of the experiment, the average excess was 7,7%. In the third week of using the probiotic, a significant increase in the survival rate of juveniles in the experimental group was noted (P ≤ 0,05).The increase in revenue in the experimental group amounted to 671,5 rub./m2.
