TEKTONO-SEDIMENTATSIONNY FACTORS AND ELEMENTS OF CONTROL OF CONDITIONS OF A BEDDING NIZHNEPERMSKIKH OF FLISHOID OF THE ORENBURG PART OF THE PREURAL DEFLECTION ^{[№ 7 ' 2015]}
In the conditions of natural deterioration of hydrocarbons and exhaustion of their stocks search of new fields is necessary for development and operation. Perspective objects for search of new sources of hydrocarbons are nizhnepermsky flishoida of the Preural deflection. Their litologo-facial characteristic is for this purpose considered. In the regional tectonic plan the area of research is located on a joint three large the nadporyadkovykh of tectonic structures: advanced folds of the Ural orogen, Volga-Ural antekliza and Caspian syneclise. As a result of research the main tektono-sedimentatsionny factors influencing thickness the nizhnepermskikh of flishoid of the Orenburg part of the Preural deflection are allocated: the tectonic movements konsedimentatsionny (covering and Ural ороген); tectonic movements postsedimentatsionny; development of the Volga-Ural carbonate platform and its onboard ledges. The basic tektono-sedimentatsionny elements controlling conditions of a bedding and lithologic structure the nizhnepermskikh of flishoid within the South of the Preural deflection are: onboard ledge Devonian нижнепермского age of the Volga-Ural carbonate platform; noncompensated hollow of nizhnepermsky age; Syurensky vzbroso-nadvig; zone of development of carbonates of an asselsky circle; large tectonic blocks of the base; the even-aged noncompensated hollow limited to a sedimentatsionny onboard ledge. Thus, nizhnepermsky flishoida of the Orenburg part of the Preural deflection are perspective objects for search of nonconventional sources of hydrocarbonic raw materials — bitumoid and slate gas.

THE DEVELOPMANT OF ECONOMICALLY EFFICIENT DIETS FOR TILAPIA IN RELATION TO INDUSTRIAL CONDITIONS ^{[№ 6 ' 2015]}
In the course of the work three recipes of diets for tilapia with different conten-tion of proteins and amino acids compositions were developed. The tests of getting diets and also the production diets of different origins were carried out in the conditions of aquacomplex of Innovative center "Aquabiotechnopark  — STC of aquaculture" ASTU, using the fry and yearlings of red tilapia. Some piscicultural, biochemical parameters of cultivated fish were analyzed, and also the resulting evaluation of production traits and their efficiency was given. The best results of weight (absolute and average growth rate), survival rate, and also fatness were shown by the fish, growing on the following diets: foreign diet (40 % protein, fat 9 %); recipe of ASTU (protein 33 %, fat 9,7 %); carp feed (protein content of 38 %, fat 9 %); catfish feed (protein content of 42.5 %, fat 11.8 %). It was revealed that the protein content was higher in the body of the fish that received diets of ASTU (33 % protein), experimental carp feed, the content of total lipids was low. It was also found that along with diets fish receives the full range of essential amino acids, which positively affects its physiological status.
