Summary
A structured narrative review of the impact of artificial light on catch performance was conducted using peer-reviewed literature published mainly during 2016–2025, emphasizing field experiments and physiological studies relevant to light-assisted capture. Blue, cyan, and green wavelengths frequently produced strong behavioral or catch responses because they propagate efficiently in seawater and overlap with the visual sensitivity of many marine organisms. However, outcomes were strongly dependent on species, fishing gear, irradiance, depth, water optical properties, and operational context. Light may also indirectly influence catch by attracting prey organisms or altering bycatch interactions.
