Evaluating the Effectiveness of Led Light Spectra Using Solar Energy in Fisheries to Improve Attraction and Sustainability

Small fishermen face daily challenges due to limited fish catches; resulting from the use of dilapidated traditional fishing tools that require continuous fuel and periodic maintenance, which increases the financial burden on the fisherman. This research aims to evaluate the effectiveness of LED light spectrums in fisheries to improve attraction and sustainability. This study focuses on the effect of different light spectra and light intensities on attracting fish, using white, blue, and green light, with intensities of 1000, 2000, and 3000 lumens at the non-full moon nights of 26th of January and 3rd of February 2023 AD (3rd Rajab and 11th Rajab 1444 AH). The study took place on the boat dock of Al-Gharam Beach, Marsa Matruh, Egypt. The results revealed a large variation in the effectiveness of different optical spectra and varying intensities. It is recommended to use 3000 lumens of white light during the non-moon nights, because it is the most effective at attracting fish. While blue was less effective and green light had a neglectable effect on attracting fish. These results contribute to the development of more efficient and environmentally friendly fishing techniques, which help improve the conditions of fishermen.
