ABSTRACT: Assessing resource-use efficiency is essential for evaluating the sustainability of fish farms. This study examined the technical efficiency of Oncorhynchus mykiss (rainbow trout) farms operating in the Taurus Mountains region of Adana, Türkiye. Using Data Envelopment Analysis (DEA), both average and individual efficiency coefficients for these farms were calculated. The findings indicated that the average efficiency coefficient was 0.732 (73.2%), suggesting that farms could achieve the same production levels with 26.8% less input usage. Additionally, 50% of the surveyed farms operated at full efficiency. Analysis of excessive input use revealed that the highest inefficiencies were in labour costs (33%), chemical use (29.1%), and feed consumption (23%). These results provided significant contributions to improving efficiency in rainbow trout farming and can support the development of more sustainable aquaculture practices.
