How does the New Moon phase impact the efficiency of light-based attraction methods?

The effect of artificial lights is significantly amplified when natural light is minimal, such as during a new moon.

The timing of recreational light-based fishing efforts is often optimized by considering the lunar cycle because the ambient light present greatly influences the contrast created by the fishing lamps. During a new moon, the absence of significant natural illumination results in the darkest possible water conditions. When this extreme darkness serves as the background, the contrast provided by the deployed artificial light source becomes much greater. This amplified contrast makes the light beacon more compelling or disorienting to the shrimp, thus likely yielding better catch efficiency for fishers deploying light attraction techniques.
