抄録

To apply the photosensory response of neon flying squid for fishing light technology, their eyeballs were investigated for retinomotor response and iris function to lighting conditions. The squid were kept under varied light intensity and duration in an onboard experimental tank. Their retinomotor response was examined histologically, and their iris function was observed between specimens with iris intact and those with iris removed. Adaptive response, which was in proportion to the quantity of light, was not recognized on the specimens with iris, but a significant response was found when the iris was removed. The results suggest that the squid has an iris function that shades excess light for their scotopic vision.
