Abstract:Different marine fish species exhibit varying sensitivities to light response.To grasp the law of fish's tendency and avoidance response to light. This paper reviews the behavioral responses of marine fishes and selected freshwater fishes, particularly pelagic economic species, to different light characteristics such as spectral frequency, light intensity, and light duration. The findings indicate the following:Fish display distinct preferences for different light colors. Pelagic fish tend to be attracted to red and yellow light wavelengths, while demersal fish show a preference for blue and green light wavelengths;Light intensity decreases with depth in the water column, making the low-light environment of the deeper waters more attractive to pelagic fish;Light intensity has a significant effect on fish growth and development, as well as on their stress behaviors and swimming patterns;With prolonged light exposure, the behavioral changes in fish primarily exhibit a triphasic pattern: an initial stress response, followed by a photoadaptation phase, and culminating in behavioral stabilization;It is crucial to strengthen research on the mechanisms behind fish behavior in response to light sources and fishing gear. By harnessing fish's behavioral responses to light, we can develop strategies to attract or repel fish, thereby laying the foundation for eco-friendly fishing practices.
