Abstract

The data on the study of the effectiveness of a new probiotic based on strains B. toyonensis B-13249 and B. pumilus B-13250 when growing shrimps are presented. The experiments were carried out on a private farm in Kazakhstan. The control group of shrimps, which did not receive the probiotic, completed the molting process on the 28th day of the experiment, and the experimental group – 10 days earlier. It was also found that the probiotic has a positive effect on the hydrochemistry of water in recirculating aquaculture system (RAS). The concentration of ammonium (NH3/NH4 +), nitrite (NO2) and nitrate (NO3-) nitrogen in the experimental group did not reach the limit value, in contrast to the control. Based on the obtained results, this probiotic can be recommended for greening aquaculture. The dosage of the probiotic when applied with brine shrimp as feed for shrimp is 1 g/100 g of dry cysts. The dosage of the probiotic when the RAS is added to the water is 5 g/600 l of circulating water once a week.

Highlights

  • Industrial breeding and rearing of aquatic animals on a large scale is accompanied by the spread of various infections

  • The aim of this paper is to study the effectiveness of use of a new probiotic preparation based on bacilli in the cultivation of Macrobrachium rosenbergii shrimp

  • Breeders of brine shrimp are interested in adding probiotic and prebiotic preparations to their product to reduce the possible development of pathogens and transfer them to shrimp prelarvae [16]

Summary

Introduction

Industrial breeding and rearing of aquatic animals (invertebrates and fish) on a large scale is accompanied by the spread of various infections. To prevent large losses during the reproduction of commercial objects, antibiotic substances have been used for many years, which led to the development of resistance to them in a large number of microorganisms. Green agrobiotechnology and probiotics in particular have become increasingly popular. These preparations can be used prophylactically to prevent the development of infections [1]. The problems of breeding these crustaceans include water pollution, lack of quality feed and outbreaks of diseases of microbial etiology [3]. To address these latter challenges, researchers are actively exploring the effectiveness of beneficial microbial agents as a probiotic supplement for shrimp
