“…A meta-analysis was performed with the results of previous studies to compare the production efficiency of the sea bass farms in Turkey with the aquaculture farms in developing and developed countries, also EU countries. The average technical efficiency coefficients of aquaculture farms in developing countries (Bangladesh 77.0%, China 79.0%, Croatia 82.0%, Ghana 74.0%, Malaysia 79.0%, Nigeria 79.5%, and Tanzania 75.0%) were calculated as 77.9%, and in developed countries (Cyprus 99.0%, France 89.0%, Greece 86.0%, Italy 84.0%, Slovenia 83.0%, Spain 93.0%) was 89.0% (Filli et al, 2016;Iliyasu et al, 2016;Yin et al, 2017;Aktar et al, 2018;Onumah et al, 2018;Ajiboye et al, 2019;Baruwa and Omodara, 2019;Mkuna and Baiyegunhi, 2019;Ashley-Dejo et al, 2020). The average technical efficiency coefficients of aquaculture farms in European Union countries were reported as 89.1% by Fernández Sánchez et al (2020).…”
