Abstract The aim of the present study was to evaluate physical carrying capacity of a potential cage aquaculture site near a Cittaslow area in the northern part of the Mediterranean (Sigacik Bay, Turkey). Developing tools for timely management of marine aquaculture facilities are important to minimize harmful influences of fish farming. The physical carrying capacity was estimated by mathematical formulations previously developed for the same area, using data of topographical characteristics of the site, production capacities, and leased area information of fish farms in total. Based on the findings of the present study, estimated physical carrying capacity of the potential aquaculture site with a total area of 38.9 ha near the Cittaslow residential area of “Sigacik Bay” was found as 27,694 tons of fish production which is more than 2-fold of the present production level that is around 11,800 tons in the area. Therefore, it might be concluded from a physical point of view that the production level of the present cage farms in Sigacik Bay is below risk levels. Keywords Aquaculture management .

Introduction The world aquaculture industry is providing high-quality food for the increasing world population expected to reach nearly 10 billion in 2050 and 11.2 billion in 2100 (UN-WPP 2017). Hence, meeting the demand for food fish of the increasing human population with food security is an important challenge for the aquaculture industry. Conflicts of coastal zone users and environmental concerns triggered the move of cage Responsible Editor: Philippe Garrigues * Murat Yigit [email protected] 1

farms to exposed offshore areas with more extension opportunities in terms of surface area lease. As a reliable food sector providing high-quality protein for human consumption, fish farms are facing new challenges in terms of social and environmental pressure. Conflicts between fish farms and other coastal zone users such as the tourism sector evoke further considerations of “site selection”, “carrying capacity assessment” and “administrative bureaucracy”.
