An Underwater Fish Attractor Light (UFAL) is a device used to attract fish in aquatic environments, especially during the night. It emits light to draw fish toward the area, enhancing the chances of successful fishing. This study aimed to design, develop, and evaluate the effectiveness of a remotely controlled UFAL, specifically tailored for gill net fishing. The UFAL was designed to improve fish capture efficiency, enhance energy consumption using chip-on-board LED technology, and ensure durability in aquatic environments. The system, equipped with a fish finder for remote operation and control, was tested for light distribution, battery efficiency, water resistance, and its impact on fish catch rates. Results demonstrated a 189% increase in total fish catch weight when using UFAL, with a total of 281.54 kg compared to 149.12 kg without it. The UFAL maintained a light intensity of 133 lux at 90° and 270° at the start, which decreased to 60 lux after 60 minutes. Battery efficiency allowed extended operation, with a voltage drop to 9.28 V at full brightness after 120 minutes. Additionally, the most effective leakage treatment achieved 0% leakage, ensuring durability.
