The Application of a Phosphorus Budget Model Estimating the Carrying Capacity of Kesikköprü Dam Lake


Abstract: The aim of this study was to estimate the carrying capacity of Kesikköprü Dam Lake, Ankara, where cage farms for the intensive culture of rainbow trout are located. For this purpose Dillon and Rigler's phosphorus budget model was applied in a series of steps and the carrying capacity of the lake was found to be 3335 tonnes per year. This estimated value was about 10 times higher than the present production level of the lake. It seems possible to orientate the fish culture in cages in inland waters by using the phosphorus budget model recommended in this study.
