Abstract
The purpose of this work was a comparative assessment of the obtained results of growing the Nile tilapia Oreochromis niloticus in fresh water with retrospective data, studying the possibility of its adaptation to salt water and the effect of water salinity (32‰) on fish-breeding and biological indicators of cultivation.
During 2 months of cultivation in water with a salinity of 32‰, the individuals from the experimental group obtained the best fish-breeding and biological indicators compared with the control in fresh water. Thus, the average daily increase was 3,4% higher, the relative growth rate was 10,7%, and the mass accumulation coefficient increased by 15,3%.
