Real-time detection and tracking of fish in a school might have multifold functions to contribute to collective behavior analysis and precision fish farming practices like individual monitoring for growth, anomaly detection, population counting, feed management, and guided and directional control for various measurements. Although the method called SORT (simple online and real-time tracking) and its extensions (e.g., SORT, OC-SORT) are widely used for tracking humans (e.g., pedestrians), such algorithms might have a great challenge to track objects with a similar appearance (e.g., animals). Among them, tracking fish in a school is much more difficult because of their similarity in size, shape, and appearance. Therefore, this research aims to compare the performance of multiple object tracking (MOT) methods, specifically SORT and its latest extension, OC-SORT, to find suitable algorithms for further applied research on various physical and behavioral measurements of fish for individual, collective behavioral analysis, and precision fish farming practices in the future.
