Coregonus albula Depending on environmental conditions in lakes, females of this species are able to breed, most often, in their second year of life, whereas the males- in third. A number of researchers stated that in some cold bodies of water of north-eastern Europe of vendace mature as late as in the third year of their lives and in the case of Siberian vendace- at the age of 4+. In polish lakes, because of the thermal conditions of waters, the vendace is ready for reproduction as early as the age of 1+. It has been confirmed in the present study, carried out in lakes of Western Pomerania. On the spawning ground, however, dominate 3-year-old fish of much higher fecundity than that of 1+ vendace. 4.0 year Czeniejewski and Filipiak, 2002

Coregonus albula Depending on environmental conditions in lakes, females of this species are able to breed, most often, in their second year of life, whereas the males- in third. A number of researchers stated that in some cold bodies of water of north-eastern Europe of vendace mature as late as in the third year of their lives and in the case of Siberian vendace- at the age of 4+. In polish lakes, because of the thermal conditions of waters, the vendace is ready for reproduction as early as the age of 1+. It has been confirmed in the present study, carried out in lakes of Western Pomerania. On the spawning ground, however, dominate 3-year-old fish of much higher fecundity than that of 1+ vendace. 4.0 years Czeniejewski and Filipiak, 2002
