Growth rate of zander (European pikeperch) was studied in the waters of Międzyodrze-the wetland area situated in the lower course of the River Odra, Poland. The fish, 546 individuals, were caught with fyke-net. Of the total number, 544 zander were aged and 379 were studied for growth rate using back calculations. Edge coefficient, Kr, was used to verify age determination. The linear growth rate of zander was similar to this characteristic of the fish living in adjacent waters in the corresponding period of time, however, clear differences were observed when compared to previous studies in the region, carried out 10 and 20 years before.
