Abstract
Paper presents the data about the catches of the Baltic sprat in the Eastern part of the Gulf of Finland from 1995 to 2021. The size and age characteristics of the sprat taken during the trawl fishing in autumn 2020-2021 are given. The analysis of nutrition and maturation, feed base and the factors limiting the fish growth is carried out.
