Abstract
The investigations of Baltic sprat have been carried out for many years, while the sprat of Bornholm Depth had never been subjected to any definite biologic analysis. Subjected to these investigations was the sprat obtained from industrial catches during 1969 and 1970. The length of body, rate of growth, age, participation of sexes, maturity of gonads and the period of spawning were investigated and determined. The stomachs of sprats were analysed for composition during the whole year.
