The carp hatched in mid-November were reared for a month in aquaria at 20-27°C and fed with zooplankton caught in littoral of a lake. During the winter the fry was kept at 10-l6°C and fed with dry feeds. By late April, the fish treated in this way were found to attain a mean individual weight of 1.29 g (the weight ranging within 0.29-4.84 g). When kept in sparsely stocked pond without any further feeding, the fry reached a mean individual weight of their first year of life.
