The use of probiotics for infectious agents of fish

Abstract

Infectious diseases of fish cause huge damage to industrial aquaculture, reducing its effectiveness and yield of fish
products. The main way to combat fish diseases in aquaculture is antibiotic therapy, as a result of which antibiotic resistance
manifests itself in drug-resistant strains of pathogens. The article presents a literature analysis on the use and effects of antibiotics
on the viability and stability of infectious agents of fish (bacteriosis). The most frequently occurring dangerous bacterial diseases
of fish are shown, the causative agents of which are bacteria of the genus Aeromonas, Pseudomonas, Flavobacterium. Thus,
at present there is a substitution of chemical preparations with biological preparations. Prospects for the creation and use of
probiotic preparation for the treatment of infections fish diseases. They are non-toxic, do not cause side effects, have antagonistic
action against a wide range of pathogens of infectious diseases of fish.
