The Impact of Various Additives in Water during the Transportation of Juvenile Fish

Abstract This paper presents the results of the studies that have been conducted to research the impact of the addition of table salt, clove oil and “Prolam” probiotic to water on improving the survival and adaptive properties of transported fish. By adding table salt and clove oil to water during the transportation of sturgeon fish, the survival rate of juvenile fish was increased by 0.4 %, and by 1.0% more in the group in which “Prolam” probiotic was added to the water in the amount of 2 ml/10 l (the fourth experimental group), compared with the control group. The adaptation time amounted to 25 minutes for the group transported in water without additives, 25 minutes for the group in which table salt was added to the water, 32 minutes for the group transported in water with clove oil added, and 20 minutes for the group transported with the addition of “Prolam” probiotic. Being further grown for 90 days, the final weight of sterbel fingerlings increased by 8.1 % when they were transported in water with the addition of “Prolam” probiotic in the amount of 2 ml/10 l. The average daily weight gain was higher in the second, third, and fourth groups by 8.4 % compared to the control group. The yield of fish products when transported with the addition of table salt was higher by 6.1%; when adding clove oil–by 3.4%; with the addition of “Prolam” probiotic–by 15.8 % in comparison with the fish transported without additives in water.
