Fecundity Rutilus rutilus L. in pool of Kama river

Is investigated absolute (AF) and relative fecundity of Rutilus rutilus from various reservoirs Prikamje. The long-term data's on dynamics of fecundity reservoirs on Middle Kama river, ponds and lakes are submitted. The individual deviations AF reach 200 multiple magnimdes (610-121210 eggs), "m" of a value also rather varies that testifies to high adaptive ability of the given aspect on a rather small part of species area.
