<![CDATA[Sustainable monitoring of aquatic ecosystems in tropical waters requires effective, adaptive, and intelligent technological approaches. This work proposes a design and evaluation of an intelligent real-time system for detecting and classifying freshwater fish species using You Only Look Once version 8 (YOLOv8), a recent deep learning architecture. The dataset used consists of 13,018 images of fishes constituting seven primary species: Catfish, Piranha, Tilapia, Betta, Milkfish, Gourami, and Koi. The research process includes preprocessing images (resizing and augmentation) and training the model using transfer learning techniques to expedite convergence and enhance accuracy. The evaluation findings show that the created system attained a maximum classification accuracy of 100% on the testing dataset. The model was successfully able to recognize species with distinct morphological traits, but a minor decrease in accuracy was reported in classifying fish with inductive body shapes. Overall results substantiate that YOLOv8 has solid potential as an efficient and replicable artificial intelligence-based approach to assisting sustainable aquatic ecosystem monitoring in tropical waters.]]>
