In this regard, the aim of the study was to assess the state of long-toed crayfish stocks in the Kigash River in the pre-estuary space. Summary data on stocks of long-toed crayfish and their biological characteristics are presented. The biological and percentage indicators of long-toed crayfish in the pre-estuary space of the Kigash River, the distribution in the preestuary space, and the maximum permissible sizes of long-toed crayfish are given.
