A recent expedition focused on hydrological and astacological studies has highlighted a decline in Kuban crayfish populations, with smaller crayfish now dominating catches. The main crayfish reserves are found in the Kulikovo-Ordynskaya and Akhtarsko-Grivenskaya estuaries. The decrease in crayfish stocks in the Azov estuaries is linked to increased salinity and illegal fishing, prompting a ban on crayfish catching since 2016. This data will help forecast crayfish stock levels in Krasnodar Territory. The region hosts three crayfish types: estuary, river, and stavochnye, with estuary crayfish being the most prized. Historically, local Cossacks were renowned for their skills in catching and preparing crayfish.
