The species composition of fish of the Streshin castle determined according to the subfossil relics of fish scale and bones numbered 24 species belonging to 4 classes. Among the revealed species there was stated kutum (Rutilus frisii) which does not inhabit the territory of the Republic of Belarus nowadays. The age for 8 species of fishes was defined.

It was established, that the basic commercial species of fish of the studied area were perch (Perca fluviatilis L.) (42,4% from the general number of revealed species), carp bream (Abramis Brama L.)
