Aquatic organism light exposure behavior acquisition device and use method thereof

The invention relates to an aquatic organism light exposure behavior acquisition device and a use method thereof. The acquisition device comprises a behavior acquisition module and a light controller. The behavior acquisition module comprises a camera obscura; a light plate which is arranged on the upper surface in the camera obscura and is used for providing different spectrums, illumination intensities and illumination periods; and a camera which is arranged on the side wall in the camera obscura and is used for recording and collecting aquatic organism movement behaviors under exposure of different spectrums, illumination intensities and illumination periods. The light controller is connected with the light plate and used for adjusting the spectrum, the illumination intensity and the illumination period of the light plate. According to the invention, the full-band spectrum can be realized, the illumination intensity and the photoperiod can be accurately regulated and controlled, and accurate environmental
