The effects of jig color and lunar bright on coastal squid jigging
Squid jigging experiments were carried out to determine whether differences occurred between different colors and lunar brightness in Middle Eastern coast of Aegean Sea. Five different colors of jigs (red, blue, green, orange and white) were used together in same angle. According to one-way analysis of variance results, red jigs were found to be the most efficient in squid capturing (p < 0.01). General linear model results proved that lunar brightness of full moon phase showed positive effects to squid catching (p < 0.01). The differences between jigs were statistically significant except between blue and green. In addition, the relationship between dorsal mantle length of captured specimens and color of jigs were not significant.
