Vendace acquired for the fecundity analysis originated from six west Pomeranian lakes: Pile (97 specimens), Ko morze (41), Drawsko (62), Pelcz (89), Morynskie (91), and Lesne (70). The fish were caught during commercial catches using anchored gillnets, 24-mm mesh size. Substantial differ ences were stated in individual biological parameters between fish representing different lakes, even if the dominant age group everywhere were 2+ vendace. The fish of Drawsko Lake showed the highest individual weight and the total length. The highest fecundity was stated in fish from lakes Komorze and Drawsko (7.21-16.85·103 and 6.9-22.23·103, respectively), whereas in Pelcz Lake this parameter reached the value as low as 1.61-4.12·103 • All vendace exhibited a high, statistically significant correlation between the absolute fecundity and their total length.
