Determination of hydrogen sulfide in samples of rainbow trout (Oncorynchys mykiss) using "SmartBiotic"

By now biological additives are used in almost all branches of agriculture to improve the quality and safety of food products.

Fish is a perishable product due to its biochemical composition. One of the indicators of fish spoilage is the detection of hydrogen sulfide in samples. The purpose of our study was to determine the effect of the use of the drug "SmartBiotic", produced on the basis of humic acids, on the quality and safety of the fish products obtained, namely, the detection of free ammonia in the selected samples of rainbow trout. Three groups of rainbow trout fingerlings (Oncorhynchus mykiss) were formed to conduct the study. One group served as a control, and the other two were experimental subjects. The first experimental group of fingerlings received the drug at a concentration of 0.15%, and the second experimental group – at a dose of 0.25%. In the control group of rainbow trout, the drug "SmartBiotic" wasn’t used.
