Background. Due to its economical importance the vendace has been considered one of the most important items of the ichthyofauna of Polish lakes. This is mainly because of favourable biological features of this species, namely: short (2-3 years) period of attaining market size, relatively fast growth rate, schooling behaviour facilitating catches, and most of all the high meat value, making it a desirable...
Vendace acquired for the fecundity analysis originated from six west Pomeranian lakes: Pile (97 specimens), Komorze (41), Drawsko (62), Pełcz (89), Moryńskie (91), and Leśne (70). The fish were caught during commercial catches using anchored gillnets, 24-mm mesh size. Substantial differences were stated in individual biological parameters between fish representing different lakes, even if the dominant...
Comparative biological and morphometric studies were carried out on vendace from lakes Drawsko and Pełcz in two seasons of the year. The summer sample covered 106 specimens of this fish from Drawsko Lake and 120 specimens from Pełcz Lake, while the autumn sample consisted of 110 and 104 specimens, respectively. This survey demonstrated a number of significant differences in the individual weights,...
