This paper has been prepared to display parameters which are used to determine the site selection of aquaculture facilities in Turkey. The Ministry of Agriculture and Rural Affairs has developed the parameters in the last three decades. During this period total farmed fish production has risen from almost nil to 33,200 ton/year. In this development, its own experiences and international experiences of foreign consultants, whose assistance was provided through the project managed by the World Bank and financed by the Government of Japan, have been utilized. At the present moment, the following parameters are considered in site selection: temperature range, salinity, areas of ground and surface and water depth, type of ground, tidal range, elevation and distance from the sea, distance from land, nature of seabed, type of pumping system, coastal topography, shelter, access, services, local infrastructure and hazards. During this survey project which was undertaken in 1993, 104 sites along the Turkish coasts were identified and have been utilized. Since it has a quite long coastline (8333 km), Turkey has the potential to expand its sites with the development of technology (offshore cages).
