| dc.description.abstract | Rigaih waters, Aceh Jaya, serve as an important habitat for various species of reef fish with high economic value, such as snappers (Lutjanidae) and groupers (Epinephelinae). However, fishing in this area still relies heavily on non-environmentally friendly gears such as gillnets, trammel nets, and longlines. One of the more sustainable alternatives is the use of pots. Traditionally, pot fishing requires natural bait such as mackerel and sardines. Unfortunately, the availability of natural bait has been declining due to overfishing and ecosystem degradation, leading to increased operational costs for fishers. This study aims to evaluate the effectiveness of blue LED lights as an alternative attractant in wire pots. The research was conducted over 18 fishing operations in Rigaih waters using three treatments: pots with natural bait, pots with blue LED lights, and pots with a combination of both. Data were analyzed using descriptive quantitative methods, ANOVA, and LSD test. The results showed that each treatment produced different responses depending on the target species. Blue LED lights were effective in attracting positively phototactic species such as red snapper (36.11%) and cuttlefish (11.11%), while groupers responded more strongly to natural bait (32.29%). The combination of lights and bait yielded the highest catches. Therefore, the use of LED lights can be considered an efficient and sustainable alternative for reef fish pot fisheries.
