Abstract:
Nelma is traditionally considered to be a delicious fish, which is no worse to sturgeons in its taste. In Russia, nelma in natural conditions lives in the rivers of Arctic Ocean basin and the Northwest region and is one of the objects promising for freshwater aquaculture, especially in Siberia. To improve the efficiency of fish cultivation in aquaculture, the preparations based on food and medicinal plants — phytobiotics or phytogenics are now widely used. These preparations do not contribute to the formation of resistant strains of microorganisms, the accumulation of toxic metabolites in the tissues of aquaculture objects and do not have a negative impact on the environment. One of the plants most commonly applied for this purpose is garlic. This famous vegetable has a wide range of phytochemical compounds that function in a complex and synergistic manner, exhibiting stress-regulating, antioxidant, immunomodulatory activity, and increase the efficiency of the digestive system. The effectiveness of the use of garlic preparations in aquaculture has been demonstrated in the cultivation of various types of commercial fish. In a present experiment, nelma fries were fed for a month with standard forage enriched with dried garlic powder in a various doses. The use of forage containing 30 g of garlic powder per 1 kg increased the survival of fish by 10% vs control. The inclusion of garlic powder to forage at a dose of 5 and 30 g per 1 kg increased the indicators of weight gain and the efficiency of weight gain by 39,8–41,9 and 37,3–40,0% vs control, respectively. The results obtained can be explained by the broad complex of biologically active phytochemical compounds of the additive.
