Cultivation of the Australian red-clawed crayfish, Cherax quadricarinatus as a new aquaculture facility in the industrial conditions of fish farms in Uzbekistan

This study explores the farming of the crayfish species Cherax quadricarinatus in fish farms within Uzbekistan. The focus is on expanding aquaculture by introducing new species. Researchers evaluated how well this crayfish can grow and adapt under controlled conditions. These conditions included temperatures of ۲۵-۲۸ °C, minimal salinity, and a neutral pH level, observed over a six-month period. The findings were encouraging: the crayfish gained an average of ۴۵ grams, achieved a daily growth rate of ۱.۸%, and required ۱.۶ units of feed to gain one unit of weight. The survival rate reached ۸۵%, indicating that the species adapts well to Uzbekistan’s climate. From an economic standpoint, farming these crayfish appears to be highly profitable. With a production yield of at least ۳ tons per hectare annually, the potential return on investment exceeds ۳۰%. Additionally, implementing water recovery systems and low-energy technology can enhance the project’s environmental sustainability. This research represents a critical step towards reducing reliance on conventional aquaculture species and supporting economic development in landlocked areas like Uzbekistan.
