In this study, the relationship between changes in the physico-chemical characteristics of water and feed consumption was evaluated using machine learning methods. Eleven physico-chemical characteristics (temperature, pH, dissolved oxygen, electrical conductivity, salinity, nitrite nitrogen, nitrate nitrogen, ammonium nitrogen, total phosphorus, total suspended solids, and biological oxygen demand) of water were assessed. Among all the measured physico-chemical characteristics of water, temperature was determined to be the most important parameter  \nto be evaluated in fish feeding. Moreover, pH2, EC2, TP2, TSS2, S2 and NO2-N parameters detected in the outlet water are more important than those detected in the inlet water in terms of feed consumption. Through regression analysis carried out using machine learning methods, the models developed with Random Forest, Gradient Boosting Machine and eXtreme Gradient Boosting algorithms exhibited higher success rates in predicting feed consumption compared to the other models. The present study highlights the pivotal role of machine learning methods in enhancing our understanding of fish feeding dynamics based on physico-chemical characteristics of water, thus contributing significantly to aquaculture management practices.  \nKeywords: Aquaculture, Feed intake, Artificial intelligence, Rainbow trout, Sustainability  \n1. Introduction  \nFish farms release various amounts of waste into the aquatic environment, which increases the necessity of examining and analysing the impact of aquaculture on the environment (Ahmad et al. 2022) . The polluted environment primarily harms biodiversity, disrupts ecological balances and prevents sustainability by affecting production (Leaf & Weber 1998; Sharma & Birman 2024) .  \nThe total trout production of Turkey was 145649 tons in 2022, and Muğla province contributed to this production with 18.2% of the total amount (Çöteli 2023). The Eşen River is at the heart of intensive trout production in Muğla province (Sezginet al. 2023; Koçer et al. 2010; Pulatsü & Yıldırım 2011) .  \nFor sustainability, it is essential to ensure that natural resources are used effectively and efficiently, in a balanced way, and in harmony with nature (Qin et al. 2024; Moldan et al. 2012) . It is necessary to know the potential and structure of natural resources well and to observ","cbCailVnpuop4Hv8","https://ap.wps.com/l/cbCailVnpuop4Hv8","pdf",1261965,2,1,9,"English","en",105,"#
