Evaluation of Production and Economic Performance of Farmed Carp Using Small Lake-Commercial Fish Farms System in Southeastern Kazakhstan.

The objective of changing the simple exploitation of fish stocks to highly efficient fish farms in lakes and reservoirs is to improve the productivity of inland freshwater fish. The small- and medium-sized lakes can be used to increase the production of farmed fish with lake management. Therefore, this study proposed to investigate the production and economic efficiency of carp in lake commercial fish farms.
