Environmental movements to return captured wildlife to nature are accelerating globally. From dolphins to killer whales, many species of marine organisms receive training to adjust to life in the wild. Different techniques can be utilized in behavioral training process including exposure to light sources (light training). Using classical training to teach Rasbora (Rasbora daniconius) to associate green light and food, other colors were tested to observe the optimum wavelength for behavioral training. Colored LED lights of blue, red, and white with short, long, and mixed wavelengths respectively were tested after complete training with green light which lasted ten days. The group of Rasbora was successfully trained to show feeding behavior when conditioned stimulus of green light was presented even in the absence of food. When introduced light of red and white, Rasbora showed feeding behavior almost identical to that of green light exposure. However, blue light elicited no clear feeding behavior in the group. As Rasbora have preference over light with long and mixed wavelengths such as red and white light, it can be inferred that red and white light is more effective in behavioral training. Blue light of short wavelength was found to be ineffective for detection of stimulus.The results demonstrated that the potential programs for returning wildlife back to nature can achieve success based on the understanding visual perceptions of marine animals such as those of rasbora.
