Investigation of the effect of a commercial probiotic-based product containing enzymes on rainbow trout (Oncorhynchus mykiss)

Abstract

In this study, the aim was to test the effect of a candidate biotechnological product developed by a commercial company and containing different probiotic bacteria and enzymes on juvenile rainbow trout (O. mykiss) and water quality. The product's protective effect against fungal infections in fish eggs and the pathogen Aeromonas hydrophila was also investigated, as were its effects on the fish's intestinal tissue. Fifty fish were placed in aquariums in two experimental setups (A and B). Different doses of the product were added to the feed in Group A and water for the fish in Group B. Four different bath doses (d1-d4) of the product were applied to fish in Group B. At the end of the study, fish in Group A demonstrated better health, growth, feed conversion, and survival rates, as well as water quality, compared to the other groups. The product was found to be effective in improving the fish's intestinal health, reducing fungal infections in their eggs, and preventing infection by A. hydrophila. The data obtained from this study aims to contribute to the development of our country's aquaculture sector.
