Abstract
Length and weight growth rates of roach as well as the length-weight relationship were determined from 196 individuals caught in 1992. Separate determinations were made for males and females and for different age groups. The von Bertalanffy equation and the binomial model were used to determine growth. Significance of differences between results obtained for 6 samples of different size, collected within July-October, was compared. Differences between growth rate indicators for the period 1974-1976 and 1992 were evaluated.
