47f: Bioadaptation to Low Doses of Xenobiotics in Aquaculture.

Agricultural and industrial activities are increasing pollution of water bodies with low doses of xenobiotics that have detrimental effects on aquaculture. The aim of this work was to determine the possibility of using 47f culture in fish aquaculture under the influence of low doses of xenobiotics as an adaptogen. An increase in the survival of individuals exposed to the xenobiotic bisphenol A solution and fed with the 47f was shown compared to control groups and, at the same time, the cytokine profile in the intestinal tissues of was also investigated.

The Effects of Acute Bisphenol A Toxicity on the Hematological Parameters, Hematopoiesis, and Kidney Histology of Zebrafish ().

In this study, the results of evaluating the acute toxicity of Bisphenol A on are presented, encompassing peripheral blood parameters, the composition of hematopoietic cells of erythroid and myeloid lines in the head kidney, and data from histological studies. The LC50 values of Bisphenol A for adult zebrafish individuals for 12, 24, and 48-96 h were determined, which were 18.04, 7.

Ability of 47f to Alleviate the Toxic Effects of Imidacloprid Low Concentration on the Histological Parameters and Cytokine Profile of Zebrafish ().

In the present article, the possible mitigation of the toxic effect of imidacloprid low-concentration chronic exposure on by the probiotic strain 47f (1 × 10 CFU/g) was examined. It was found that even sublethal concentration (2500 µg/L) could lead to the death of some fish during the 60-day chronic experiment. However, the use of 47f partially reduced the toxic effects, resulting in an increased survival rate and a significant reduction of morphohistological lesions in the intestines and kidneys of .

Effects of Three Feed Additives on the Culturable Microbiota Composition and Histology of the Anterior and Posterior Intestines of Zebrafish ().

In this study, the effect of three promising feed additives (chelated compounds of trace elements, butyric acid, lycopene) on changes in the culturable microbiota and histological parameters of two sections of the intestines of (zebrafish) was studied. The use of these feed additives can help to eliminate the deficiency of trace elements, modulate the composition of the microbiota due to the postbiotic properties of butyric acid, and reduce oxidative stress when using lycopene. Incorporation of the investigated supplements in the feed resulted in a significant change in the relative abundance of certain groups of microorganisms.

The experience of using a mineral chelate additive for growing juveniles of the African sharptooth catfish (Clarias Gariepinus) in a recirculating aquaculture system.

Growing fish in a recirculating aquaculture system (RAS) involves various stress factors that directly affect their physiological condition. This study aimed to investigate the effect of a chelated organic-mineral additive including Fe, Mn, Cu, Zn, Co, Se and I; on the rearing performance of juvenilecatfish (Clariasgariepinus) under RAS conditions. Four groups of fish (n=50) were formed: a control group (receiving standard feed) and three experimental groups (receiving standard feed with biogenic elements chelate compounds in different concentrations).
