This dual spectrum for saury and squid is specifically designed for vessels targeting both saury and squid, as well as migratory fish species, It seamlessly integrates the spectra required to attract saury and cephalopods within a single luminaire. Introducing a dual-purpose fish aggregation light that can attract both saury and squid, it significantly reduces the procurement costs of vessel lighting equipment. Additionally, it eliminates the need for large-scale light replacement operations. This allows captains to easily meet their varying spectral requirements for different fishing seasons, effectively increasing catch yields.
