چکیده

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 25-28 °C, minimal salinity, and a neutral pH level, observed over a six-month period. The findings were encouraging: the crayfish gained an average of 45 grams, achieved a daily growth rate of 1.8%, and required 1.6 units of feed to gain one unit of weight. The survival rate reached 85%, 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 3 tons per hectare annually, the potential return on investment exceeds 30%. 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.
