Özet
In this study, more than 3 tons of businesses operating within the scope of net cage rainbow trout production is examined in Kahramanmaras province. In this context, six rainbow trout production firms were identified, and their structural and biotechnical analyzes were done. Face to face interview survey has been done for all of the enterprises, data are collected from businesses in order to reveal the current situation and problems. According the obtained data, the average total project capacity of enterprises is 1.008 tons/year, average total production capacity is 428 tons/year, and average feed conversion ratio (FCR) is 1,24. The average water surface area leased by businesses was calculated as 9.036 m(2). In addition, areas leased by businesses and the production of their fields (productive area) was calculated by taking the average of 24% utilization rates of water area. Harvesting density of the net cages is 15.4 kg/m(3) and enterprises average capacity utilization rate is determined as 60.91%. Aim of this study is to determine capacity of net cage aquaculture enterprises and encountered technical problems in Kahramanmaras province; thus, information obtained from the development of the sector is carried out to investigate and propose solutions to increase productivity. Results are given next in accordance with the objectives of the study; net cages are utilized not efficiently, density of stock is low, feed conversion values are high, capacity utilization rates and the water area usage is low. According to the data obtained from this study the followings should be done to enhance the efficiency of enterprises. Organization, to use high-quality feed, run-trained staff, regular record keeping and strict control of competent authorities.
