"Mikulíková, I., Radojičić, M., Banďouchová, H., Blahová, J., Papežíková, I., Minářová, H., Lepková, Z., Toulová, I., Palíková, M., 2023. The effect of Lactiplantibacillus plantarum R2 Biocenol™ on gut microbiota, growth performance and health status of rainbow trout Oncorhynchus mykiss. 21st International Conference on Diseases of Fish and Shellfish, Abstract Book, European Association of Fish Pathologists, Aberdeen, UK, 11.–14. 9. 2023, p. 180. Introduction: Intensification of fish production may be connected with outbreaks of diseases as well as with negative effects on the growth parameters of fish. One of the possible ways to cope with these problems seems to be the use of probiotics. Our study aimed to evaluate the effects of diet supplemented with Lactiplantibacillus plantarum R2 Biocenol™ (CCM 8674) isolated from intestine of healthy rainbow trout on specimens of the same species. We also compared the effect of two different feeding strategies. Methodology: There were 3 groups of fish – the control, the fish fed for 7 weeks by commercial feed with added bacterial cells of L. plantarum R2 Biocenol™ (continuous supplementation) and the fish fed with this enriched feed for 4 weeks, followed by 3 weeks of control feed (initial pulse supplementation). The fish were sampled after 7 weeks and growth performance, gut microbiota, immunological, haematological and plasma biochemical parameters were assessed. Results: L. plantarum R2 Biocenol™ (CCM 8674) was shown to improve growth performance of rainbow trout when provided by both feeding strategies. Although the effect of the pulse probiotic supplementation on the intestinal microbiome community was not permanent, a statistically significant difference was found in the composition of the bacterial community associated with the mucosa in both probiotic-provided groups of fish. Continuous supplementation significantly increased blood haemoglobin and haematocrit levels and reduced plasmatic chloride concentration. Significantly decreased concentrations of plasmatic magnesium and calcium were revealed in probiotic pulse-fed fish. Conclusions: With regard to assessed indices, the tested strain can be recommended for further studies concerning its use in rainbow trout aquaculture."
