| Abstract: | ABSTRACT: The optomotor reaction of the red sea bream Pagrus major was utilized in order to measure its spectral sensitivity. The high spectral sensitivity of this species in twilight conditions was estimated to be from 480 to 560 nm, whereas it was observed to be also on longer wavelengths in the probable photopic vision. This result was compared with the sensitivity curve obtained by the physiological technique of the induction of electroretinogram. The form of both sensitivity curves did not show similar tendencies. It will be necessary to investigate the adjustment of a physiological phenomenon and a behavioral phenomenon concerned with various stimulus-reaction systems. |
