Kurakin I.V., Mikhailichenko D.V., Ponomarev S.V., Fedorovykh Yu.V., Bakaneva Yu.M., Miroshnikova E.P. THE DEVELOPMANT OF ECONOMICALLY EFFICIENT DIETS FOR TILAPIA IN RELATION TO INDUSTRIAL CONDITIONSIn 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.Key words: tilapia, diets, recipe, fish meal, protein, fat, energy.
