The estimation of the carrying capacity of a Hasanuğurlu dam lake fot the intensive raninbow trout culture incage

The most important factors related to the sustainability of fish farming in network cages; water quality parameters that make up the ecological conditions of the environment and environmental transport capacity. In this study, some water quality parameters of Hasanuğurlu Dam Lake were monitored for two years and some evaluations were made on trout farming and lifting capacity in the lake considering the results obtained. The research area is located within the borders of Tunceli province and the most important water source of Yeşilırmak Stream, one of the branches of Fırat . The aim of this thesis is to estimate the carrying capacity of Hasanuğurlu Dam Lake for trout farming (Onchorhynchus mykiss) in cages by using phosphorus loading model. As a result; Acceptable phosphorus load 31 mg / m3, feed utilization ratio1.0- 1. 5-2. 0 between the accepted and other sources without taking into account the contribution of phosphorus, the average depth of 47 m and the surface area of 22.7 km2 Hasanuğurlu Dam Lake can be cultivated in the cages trout amount approximately 500 tons / year.
