The database of final values of weight of body, of length before the middle beams of tail fin by one-years of pikeperch is presented. This database is presented in version of variation series. The connection between got values of these parameters and parameters of fish-productivity by the one-years of pikeperch was traced. The fact that for most value of fish-productivity according to the one-years of pikeperch which was got by most hardness of planting on the level of 12500 things/ha the most difference of values of mass of body, predominance the fishes with the mass of body less than the middle value, is established. The fact that the increase of middle value of length of body by one-years, predominance the fishes with the length of body before the end of middle beams of tail fin more than middle value by the decrease the hardness of planting before 5000 - 10000 things/ha is established. The fact that bringing near the middle, modal and medianal values of final mass of the body, predominance the fishes with mass of body more than middle value by minimal hardness of planting which is less than 5000 things/ha is established. The predominance of one-years of pikeperch by large size group by minimal values of hardness of planting is established. The predominance of one-years of pikeperch by middle size group by the increase of hardness of planting for 100 and 150 per cents is established.
