Keywords:
Early Stress Detection, Machine Learning, Aquaculture, Water Quality, Random ForestAbstract
Purpose: This study aims to develop a machine learning–based approach for the early detection of stress in cultured fish by analyzing fluctuations in key water quality parameters. Early identification of stress conditions is essential for maintaining fish welfare, reducing mortality, and improving the productivity of intensive aquaculture systems.
Subjects and Methods: This study employed a quantitative experimental approach to develop a machine learning–based model for the early detection of stress in cultured fish using water quality parameters. Water quality data, including dissolved oxygen, ammonia, pH, nitrite, and temperature, were continuously collected from an intensive aquaculture system using environmental sensors. Fish behavioral indicators were used to label stress and non-stress conditions. Three machine learning algorithms Random Forest, Support Vector Machine, and Artificial Neural Network were applied and evaluated using accuracy, precision, recall, F1-score, and AUC metrics.
Results: The results indicated that dissolved oxygen and ammonia were the most significant predictors of fish stress, while pH and nitrite played supporting roles in influencing stress dynamics. Among the tested models, the Random Forest algorithm demonstrated the highest accuracy and stability in predicting stress conditions. The model effectively captured nonlinear relationships and temporal patterns within the dataset. Based on this model, an early warning system was developed to detect potential stress several hours before visible physiological or behavioral symptoms occurred.
Conclusions: The integration of continuous water quality monitoring with machine learning techniques provides an effective predictive framework for aquaculture management, enabling proactive interventions, improving fish welfare, and supporting sustainable aquaculture practices.
