The invention relates to fish farming, methods of fish breeding, in particular to feeding sturgeon.

There is a known recipe for compound feed for the Russian sturgeon with the product of lupine as a component in extruded feed, made at the Scientific and Technical Center "Aqua-feed" All-Russian Research Institute of Freshwater Fisheries and at the Krasnodar Research Institute of Fisheries (Sklyarov F.V.

Known feed concentrate for highly productive lactating cows, characterized by the fact that it contains corn grain, barley grain, sunflower meal, rapeseed cake, white lupine Degas, wheat bran, premix P60-4, monocalcium phosphate, table salt, while the original components are taken in the following ratio, wt. %: corn grain 17.0-28.8; barley grain 25.6-44.0; sunflower meal 3.2-6.0; rapeseed cake up to 6.9; grain of white lupine grade Degas 18.0-30.0; wheat bran 4.0-14.0; premix P60-4 1.0-1.2; monocalcium phosphate 1.5-1.6; table salt 0.5-1.2 (RF patent No. 2681485 C1, published 2019.03.06) https://yandex.ru/patents/doc/RU2681485C1_20190306.

For the prototype, the recipe for compound feed for the Russian sturgeon with the product of lupine as a component in extruded feed, made at the Scientific and Technical Center "Aquakorm" All-Russian Research Institute of Freshwater Fisheries and (Sklyarov F.V. Efficiency of using lupine and sorghum in compound feed for young sturgeon and carp Thesis ... Candidate of Biological Sciences.

The disadvantages of the known formulations include the use of soybean oil instead of sunflower oil, as well as the high content of fish meal, which is often not stable in terms of protein level, depending on the quality of the raw material.

The task is to expand the range of domestic production feeds for growing sturgeon.

The technical result is an increase in the absolute, average daily and monthly gain and the body condition coefficient.

The technical result is achieved with a food product consisting of fish meal, white lupine product, wheat flour, premix and vegetable oil, while additionally contains blood meal, feed yeast, protein concentrate Agro-Matic is used as a lupine product; Premix MEGA-MIX GOST 1% for fish, sunflower oil is used as vegetable oil, with the following ratio of components per 100 g of the finished product, g:

Fish flour 45 Blood meal five Protein concentrate "Agro-Matic" fifteen Wheat flour eighteen Fodder yeast nine Sunflower oil 7 Premix MEGAMIX GOST 1% for fish 1

at the rate of feeding the sturgeon per day in the amount of 2% of the body weight, with a frequency of manual feeding 5 times a day.

Protein concentrate "Agro-Matic" In addition, it consists of flour of white lupine beans of modern low-alkaloid varieties (crushed in several steps in special crushers), as well as poultry meat and bone meal.

Premix MEGAMIX GOST 1% for fish contains vitamins: A, D3, E, K3, B1, B2, B3, B4, B5, B6, B12, biotin, folic acid, trace elements: iron, copper, zinc, manganese, cobalt, iodine , selenium, magnesium, antioxidant.

An example of a specific implementation.

For the preparation of feed for 1000 g, fish meal was used - 450 g, blood meal - 50 g, Protein concentrate "Agro-Matic" - 150 g, wheat flour - 180 g, feed yeast - 90 g, sunflower oil - 70 g, premix MEGAMIX GOST 1% for fish - 10 g.

All the ground components that make up the compound feed were sieved and a mixture of dry components was prepared. Protein concentrate "Agro-Matic" was added to the resulting mixture, mixed thoroughly.

Experimental work was carried out in the period from January to May 2018 in the conditions of the Problem Research Laboratory "Breeding valuable sturgeon breeds" of the Volgograd State Agrarian University. Four experimental groups were used as objects of research, including one control specimen of the Siberian sturgeon species (Lena population) (Acipenser baeri Brandt) 4 months old. The initial weight of the experimental individuals was 150 g.

The dynamics of the live weight of sturgeons was determined by the results of weekly weighing, on the basis of which the absolute and average daily gains, as well as the fatness coefficients were calculated.

Analysis and generalization of experimental data obtained during research on assessing the effectiveness of the use of protein components of domestic production in compound feeds for valuable species of fish (sturgeon) made it possible to draw the following practical and theoretical conclusions.

As a result of the experiment, the best results in terms of absolute gain in live weight were obtained by individuals receiving feed containing protein concentrate; they exceeded their peers from 2-, 3- and control groups, respectively, by 6.01, 9.02 and 16.63%. In terms of the absolute increase in body length, the individuals who received feed containing protein concentrate exceeded their counterparts from the 2nd, 3rd and control groups by 5.30, 10.78 and 2.47%. In terms of body height, the best results were also recorded in this group, they were 6.5 cm.

The highest average daily gain was also recorded in individuals fed feed containing protein concentrate, according to this indicator, they dominate over their peers in the control, 2-experimental and 3-experimental by 2.47, 5.30 and 10.78%, respectively. The best indices in terms of the coefficient of nutritional status were also observed in the animals of the 1st experimental group, they exceeded the analogs from the 2nd and 3rd experimental groups.

Thus, the declared commercial food for sturgeon provides an increase in the absolute, average daily and monthly gain and the coefficient of body condition.
