Vendace, Coregonus albula (L.), catch and stocking data obtained from 24 fish farms using vendace lakes (total surface area of 22311.77 ha) situated in northwest Poland were analyzed. The average total fish yield from these lakes was 12.53 kg ha⁻¹, of which the average share of vendace was 18%. The highest vendace yield was obtained in lakes with water surface areas of less than 250 ha and with an...
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...
Pluszne Lake, with an area of 903 ha and a maximal depth of 52 m, is located in northeastern Poland. It is a typical mesotrophic lake, and its resources of pelagic fish are dominated by vendace and smelt. A Simrad EY-M research echosounder (70 kHz, single beam) and a complementary HADAS computer data analysis system were used for fish distribution and density estimation. Control catches were carried...
