Abstract
Data are presented on diurnal and seasonal dynamics of feeding of the tench Tinca tinca in a small eutrophic water body. The feeding spectrum of tench includes 60 taxa of aquatic invertebrates. Most of them (37 species) are chironomid larvae. The highest feeding intensity is recorded in the intervals from 6:00 to 9:00 p.m. and 12:00 a.m. to 3:00 a.m. The maximum value of the index of consumption is recorded in August; the minimum value is recorded in July. The feeding spectra of fish aged 6–7 years old differ considerably (the Morisita–Horn index) from 1 year older or younger fishes.
