The purpose of this study was to examine the relationship between squid productivity and light intensity in the waters off the East Coast of North Sumatra. Research into the effects of different light colors is important because it is currently unknown which hue of light from flashing LED lights most effectively influences squid catch. The study was conducted in North Sumatra in January and February of 2024, with the waters off the province's east coast serving as the study site. Survey research, a form of non-experimental research, was used to collect data in the field. This study involved 16 repetitions and 2 treatments. The results indicated that the total weight of squid caught using white lights was 56,418kg, while the catch using yellow lights was 31,968kg. In total, the squid catch from both light colors amounted to 88,386kg. Interviews with fishermen revealed that squid caught by Bagan Pung fishermen are sold at IDR 30,000 per kg. Additionally, anchovies are sold for IDR 15,000 per kg, tembang fish for IDR 8,000 per kg, and layur fish for IDR 25,000 per kg.
