Using of the computer software for the sustainable rainbow trout cage culture: A case study in Gökçekaya Dam Lake (Ankara, Turkey)

14438

The aim of this research is application of a computer software for the developing sustainable cage aquaculture named -Cage Aquaculture Decision Support Tool- on high capacity (950 tons year-1) rainbow trout cage farm in Gökçekaya Dam Lake. The modules of the computer software program: i) site classification, ii) site selection, iii) holding density-carrying capacity and iv) economic appraisal is applied at selected cage farm. The cage farm is classified into three categories - poor, medium, and good- according to set of criteria (water- substrate qualities, hydrometeorology and socioeconomic) and sub-criteria of site classification and site selection modules. Holding density which is the other computer software module is determined in cage farm as 17,72 kg m-3. Carrying capacity of the dam lake is estimated in cage farm’s inputs as 2.056 tons year-1. In the economical appraisal module; return on investment are calculated as ≅ 127% using cage-holding density and some economic parameters. Being a fast and easily applicable, the programme proposed to be used as a case study of the Gökcekaya Dam Lake, is thought to play a key role in the subject of the management of different cage farms in distinct ecological areas and monitoring of the environmental impacts of fish farming in Turkey.
