Summary. The search for effective and environmentally friendly
means to increase the productivity and natural resistance of animals,
especially in aquaculture, remains an urgent socio-economic task. This article
presents the results of the study of the effect of the cryobiological
supplement ‘Immunolife-Fish’, based on medicinal plants, on the
weight gain of juvenile common carp (Cyprinus carpio) and indicators of
innate immunity of two-year-old common carp (Cyprinus carpio) and silver
carp (Hypophthalmichthys molitrix) under the influence of thermal stress
factor in aquarium conditions. It was found that the weight gain of juvenile
carp treated with the cryobiological supplement ‘Immunolife-Fish’
was higher than that of the control group at all stages of the study. The
increase was most pronounced during the first 42 days of feeding. A
significant increase in the number of leukocytes was found in the blood of fish
(common carp and silver carp) exposed to a heat stressor compared to control
values. In fish that received a supplement of the herbal preparation during stress,
this indicator only tended to increase. The effect of the stressor in fish of
both species is manifested by a significant increase in the leukocyte content,
a decrease in the indicators characterizing the functional state of cellular
immunity — phagocytic activity and number of phagocytes, as well as
a tendency to decrease the phagocytic index of neutrophils in the blood. The
use of the cryobiological supplement ‘Immunolife-Fish’ in fish
exposed to stress not only prevented the decrease in the phagocytic activity of
neutrophils but also contributed to a slight increase in their activity in
comparison with the control. A significant decrease in the activity of lysozyme
and the level of circulating immune complexes, as well as an increase in the
content of seromucoids, was found in the blood serum of common and silver carp
under the influence of the stress factor. The use of the drug against the
background of stress leveled the negative changes in the above indicators
characterizing the state of the humoral link of innate immunity. In addition, a
mild immune stimulating effect of the cryobiological supplement on fish of both
species, which were kept in optimal conditions, was noted. The research is
aimed at the development and testing of organic, environmentally friendly
anti-stress and immunostimulant agents in commercial fish farming
