BIOLOGICAL ACTIVITY OF URBAN SOILS (ON THE EXAMPLE OF ROSTOV-ON-DON)
DescriptionAbout 40 soil cuts were made in various parts of the city of Rostov-on-Don. The determinations of enzyme activity (catalase, invertase, polyphenoloxidase) were carried out in natural and antropogenic soils of a sub-urban park, residential and industrial areas of the city. The enzyme activity of soils in urban condition signif-icantly lowers than in non-urban soils. It is established, that significant impact on the biological activity has duration of sealing, and the longer the period, the higher the negative impact on the enzymes activity. However, a close relationship between humus state of soil and its enzyme activity kept in a condition of ur-ban pedogenesis. The high activity of investigated enzymes is typical to soil horizons which contain the highest amount of soil organic matter

BIOLOGICAL CHARACTERISTICS AND COMMERCIAL STOCKS OF HUMPBACK WHITEFISH IN YAKUTIA WATERS
DescriptionHumpback whitefish - Coregonus lavaretus pidschian (Gmelin, 1788), is spread in Siberia, in the Kara, Laptev and East Siberian seas and in the lakes of the Arctic and Subarctic. Objective: To assess the status of fish in the waters of Yakutia, to make ecological forecasts and determine the possibility and prospect of economic use of whitefish, as a fish-breeding material in the present conditions. Methods: The analysis was carried out on the fresh material as described I.Pravdina (1966), taking into account the recommendations of Y. Reshetnikov (1980). Collection and processing of materials were carried out in 1969-2015 by standard methods. Results. Reaching sexual maturity at the sixth (in weight - the eighth and ninth) year of life, whitefish begin to move to the main breeding groundsin the early fall. Absolute fecundity of eggs 2500-140000. Spawning is common in late September-early October. The food spectrum usually consists of the following objects: chironomid larvae, plants, mollusks, fish eggs and copepods. By the nature of power - benthophage, but often becomes planktonic organisms. Conclusions. Important food fish, but its reserves significantly reducedunder the influence of anthropogenic factors in recent years. The catch of whitefish can be increased as a result of the development of aquaculture

BIOLOGICAL VALUE OF PLANT PROTEIN AND VITAMIN SUPPLEMENTS
DescriptionResults of the use of plant protein feed additives containing pumpkin paste and soybean seeds of different varieties for quail are presented in the article. It was established that the use of such additives on the basis of Valens soybean allowed to receive higher growth parameters than groups treated with Vilan soybean additive
