Study of the biochemical composition of sturgeon blood using a cyclodextrin complex with enterosgel

The biochemical picture of blood allows not only to determine the effect of antimicrobial drugs on the body of fish, adaptation to the conditions of water bodies, but also to determine the physiological state of aquatic organisms. The purpose of the study was to study the effect of cyclodextrin complex with enterosgel on the biochemical parameters of the blood of young sturgeons. For the studies, experimental groups were formed according to the principle of pairs-analogues in the amount of 10 specimens in each group: 1st control and 2nd control groups were characterized by an impaired functional state of the body. No therapeutic measures were carried out with them, levofloxacin with enterosgel was not introduced into the compound feed. The differences were that individuals of the 1st control group were given high-quality feed, while the 2nd control group was given poor-quality feed. The 1st experimental and 2nd experimental groups received high-quality feed, they underwent therapeutic measures, and they were characterized by an impaired functional state of the body. The differences consisted in different concentrations of the administered drug – 15 and 10%, respectively. The total protein content of fish on the 8th day in the 1st and 2nd experimental groups was 77.60 ± 0.80 and 84.90 ± 3.43 g / l, respectively, which is 7.87 g / l and 0.57 g / l lower than in the 1st control group. In terms of total protein content, the control groups had virtually no differences between themselves with 86.33 g / l and 86.63 g / l respectively. In sturgeons from the experimental groups, the indicator was lower than the control values by 9.76 g / l and 3.86 g / l. Analysis of the content of macro elements showed that their values by groups were approximately at the same level and did not go beyond the norm. According to the obtained values of phosphorus concentration in the blood, the optimal values were observed in sturgeons of the 2nd experimental group, which received the studied complex with a fluoroquinolone content of 10%.
