Аннотация

For the first time that 23 species of hydrobionts are distributed in the Zarafshan National Nature Park and 16 species are studied in the Ziyovuddin region by us. In the lower part of the Zarafshan river, the number and density of species is less than in the upper part, which is due to the pollution of the waters. Corbiculina tibetensis and C. ferghanensis, which are widely adapted, are dense in the lower part of the river. The species density of Colletopterum bactrianum, Colletopterum cyreum sogdianum, Corbicula cor, Corbicula fluminalis, Corbicula purpurea, Pontastacus leptodactylus and Hirudo medicinalis is found to be low.
