Carp (Cyprinus carpio L.) is domesticated in every continent except Antarctica, owing to its ability in adapting to different values of water quality parameters, including tolerance to very low dissolved oxygen concentrations. Considering the benefits that are reflected by the extensive reproductive abilities, breeding and prime selection potentials, and high resistance to various diseases, it is not surprising that carp represents the dominant species in all counties with prerequisites for extensive, semi-intensive and intensive freshwater fish production. The carp growth in different production systems depends on many factors, such as varietal, density, welfare and fish feed with proper nutrients along with geographic location. Cage production system for carp is a special type of intensive production. It is characterized by lower initial investments in cage construction and minimal labor engagement, ensuring high production yield per volume capacity of water contained in the constructed units. Modern cages are constructed from metal and synthetic polymers (Mihailovic et al., 2007). Cage has to be robust enough to endure associated hazards such as winds and waves, uncomplicated servicing and maintenance. Location choice is critical as it affects the production and mortality of the produce (Carp) directly impacting the profitability of the production unit. Below listed are three-selection criterion considered for selection of sites for cage culture (Bogut et al., 2007). 1. Physical and chemical parameters including temperature, dissolved oxygen concentration, water flow, pollution and algal blooms. 2. Factors relating to the choice of location taking into account weather conditions, shelter, substrate, water currents and the degree of blur. Additionally the shape and size of the cage and the depth to which they are installed. 3. Profitability of the farm, and includes legal aspects, accessibility, facilities, security, economic and social conditions. Superior production practices, quality of water and optimally ...
