The aim is to form annual overviews of Finland’s fish populations, especially vendace populations, and to forecast their development. The objective of population inventories is to produce information that can be used to manage fishing and fish resources and to promote the bioeconomy and sustainable use of natural resources. Data on the relative abundance of vendace populations are collected from about 80 lakes which are important for commercial fisheries in Finland.
Results of the questionnaire sent to fishermen and researchers are published every year in early summer on the internet pages of Luke, articles are published in professional magazines. Results are also published in reports as well as in scientific articles.
