During the juvenile development (0+ to 5+) the specific growth rate (SGR) decreased successively from 17.67 to 0.05 %.d-1. During the adult period of development (6+ to 13+), the SGR fluctuated from 0,0191 to 0,0562, mean = 0,0410 %.d-1. In addition, body weight condition and length-weight relationship are presented. The adult period commenced at average age from 4 to 5 years. At the end of subsequent 13 years of life (1st-13th), following values of TL/w (mm/g) in reared sterlet were determined: 250/53, 350/174, 400/250, 440/320, 465/400, 490/462, 516/525, 546/645, 561/720, 596/860, 610/1014, 625/1199, 660/1456. A very fast growth intensity was determined in the young sterlet (1st and 2nd year) while it decreased in the older fish.
