ABSTRACT


Vendace landings were analysed against the background of catches of other commercially important fish species in the lakes Ińsko and Woświn. The detailed morphometry of the lakes as well as basic information on the chemistry of their water are provided. The total fish yields in both lakes were found to be much lower than the overall mean Polish yield; the total yields in the Ińsko and the Woświn amounted to 15.88 and 18.26 kg·ha-1, respectively. Vendace contributed 34.12 and as little as 7.72% to the total yield in the Ińsko and the Woświn, respectively. Most probably, the difference is a result of a poorer water quality in the Woświn the anoxic layer in which begins at the depth of 10 m in summer. According to the vendace catch-based classification system of [3], Lake Ińsko belongs to “good” lakes, while Woświn should be classified as “poor”.

Key words: Lake Ińsko, Lake Woświn, vendace management.
