RESULTS OF STARTER DIET DEVELOPMENT FOR STURGEON LARVAE BY USE OF SPART PROTEIN HYDROLYSATE AND PROBIOTIC "BIFITRILAK"
The purpose of these studies is to develop and biologically test a sturgeon larvae starter diet which includes fish disrupted protein component and probiotic “Bifitrilak” (Bifidobacterium spp. and Lactobacillus spp.). Six pilot batches of larvae feed are produced. Larvae of Russian sturgeon ( Acipenser güldenstädtii ) have been grown for 24 days until they reached the young fish sdevlopment stage. While using the probiotic “Bifitrilak” in the structure of sturgeon larvae starter diet with or without adding sprat hydrolysate, there has not been fixed its strong positive effect on the larvae mass growth during the process of transition to active feeding. Besides, there has been observed the increase of fish survival rate while using the probiotic without hydrolysate additive. In the following experiments it is recommended to use the technology of micro-encapsulation for water-soluble hydrolysate.
