The age and length distribution of the blue bream spawning population of Międzyodrze-the wetland area in the lower part of the river Odra-was examined in the years 1992-1996. The length and age of sexual maturity was determined, the relative gonads size of mature fish in autumn and spring seasons as well as relationship between fecundity and weight or length of females was assessed.
