Abstract

Lighting systems combining light-emitting diodes (LEDs) and metal halide lamps (MHs) are expected to be energy-saving tools in Japan’s squid jigging fishery. Previous research has shown the need for light stronger than LEDs (9 kW) and 36 MHs (108 kW) to catch the Japanese common squid Todarodes pacificus. We tested a stepwise lighting method termed “stage reduced lighting” in the Tsushima Strait in January and February 2010 using nine fishing boats. LEDs (9 kW) and 50 MHs (150 kW) were lit for 3.9 h on average, and then the number of MHs was reduced to either 30 or 36 until the end of fishing (7.3 h on average). This method reduced fuel consumption by 22–25 % compared to the continuous use of all fishing lamps (159 kW). We carried out a catch analysis of nine experimental boats and 21 commercial boats during the experimental period. Generalized linear modeling analysis suggested that the squid catch can be explained by the illuminated fraction of the moon and monthly changes in squid abundance, and the lighting method. The stage reduced lighting using LEDs and MHs has the potential to reduce fuel consumption while maintaining the squid catch.
