Abstract
   The aim of the current paper was to establish the growing rhythm of Cyprinus carpio breed using as food the Aller classic fodder. In the first stage a pond with a surface of 0.5 ha was populated with crap sapling. The total number of the sapling populated in this pond was 3000 individuals with an average weight of 70 grams per individual. To establish the growing rhythm were made, twice per month, a control fishing. The current research was realised in a farm from Moldova region in 2014.
   Experiment started in April when the water temperature reached a value of 16°C. After first control fishing, fishes were assigned in three categories function of their weight. Monitoring of biological material took place from April till September resulting a fishes' mean weight from 70 g/individual till 1024 g/individual and the gain was of 1 kg fish for 1.7 kg administrated fodder. For a better development of fishes was kept under control the level of solvit oxygen at a value of 7 mg/l using some aerators. At the same time were administrated lime chloride and antibiotics due to apparition of some specific breed diseases.
