This study investigates the effects of different music genres on the swimming behavior and stress responses of tilapia (Oreochromis niloticus), with implications for commercial aquaculture welfare management. Fish (mean weight: 45.3 ± 5.2 g, n = 75) were exposed to classical music (P1), rock music (P2), pop music (P3), electronic music (P4), and a control group (P5) for 30 min daily over four weeks. Swimming velocity (FSV), stationary time, and total distance traveled were measured using cost-effective computer vision techniques with Tracker software. Classical music induced the highest FSV (0.0199 ± 0.004 m.s⁻¹), representing a 90 % increase compared to the control group (p < 0.001), while also promoting stable swimming patterns. Rock music caused the most erratic behavior, with a 45 % increase in movement variability compared to the control (p < 0.01). Economic analysis revealed implementation costs of USD 50–100 per 1000 m² pond, with a potential return on investment within six months due to reduced mortality (projected 10–15 % improvement) and enhanced growth rates. Water quality parameters remained stable throughout the study (DO: 6.5 ± 0.3 mg/L, pH: 7.2 ± 0.2, temperature: 28 ± 1°C). These findings demonstrate that passive acoustic treatment using musical stimuli, particularly classical music, can offer a cost-effective and non-invasive stress management tool for intensive tilapia farming, potentially improving welfare standards and productivity in global aquaculture operations. © 2026 Elsevier B.V.
