OCA15. Annotation of the output with contextual information concerning the description of creative process and the content of the research/artistic/other activity, etc.	It can be stated that the invented technology based on the combination of dry coating of pellets with colloidal silicon dioxide followed by coating with a starch hydrogel containing a probiotic creates a mechanically resistant coating on the surface of the oleophilic pellets. Moreover, this process did not worsen pharmaceutical parameters, including the surface and sphericity of feed pellets. L. plantarum R2 showed tolerance to low pH levels and a good ability to release into this environment during a 24-hour period. Temperature plays a significant role in the viability of probiotic bacteria, but based on our results, we can say that storage at 4°C is optimal for the maintenance of viability and good quality of pellets, even for long-term storage. Based on Sanger sequencing, the presence of plantaricin-related genes (plnA and plnEF) in the tested strain was confirmed, which is a prerequisite for their possible production, which must be confirmed at the protein level. In conclusion, we can say that designated coating technology and chosen probiotic bacteria are suitable for the preparation and use of probiotic pellets in in vivo experiments and, later, potentially in farm breeding.

OCA18. Characteristics of the output's impact on socio-economic practice	The output brings new knowledge about the possibilities of using bacteria of the genus Lactobacillus, obtained from the gastrointestinal tract (GIT) of rainbow trout (Oncorhynchus mykiss), for feed supplementation to improve the health and quality of meat in farmed fish farming.
OCA19. Characteristics of the output and related activities' impact on the educational process	The contribution addresses the health and welfare of animals during fish farming and their impact on the quality of meat produced. At the same time, it addresses the possibilities of using probiotics in the nutrition of farmed salmonids. The outputs of the article concerning the feed production for aquaculture will be used in teaching the subject Legislation requirements for feed and food production.
