Aquatic animal illumination selection experimental system

Provided is an aquatic animal illumination selection experimental system. The aquatic animal illumination selection experimental system is characterized by comprising a shell body (1), wherein a large separating board (2) which is capable of lifting is arranged in the shell body (1) along the axial direction, an inner cavity of the shell body (1) is divided into a dark area (3) and a bright area (4) by the large separating board (2), a plurality of small separating boards (5) are arranged in the bright area (4) along the radial direction of the shell body (1), and are used for dividing the bright area (4) into a plurality of small separating rooms (6), a white lampshade (7) with adjustable height is arranged in each small separating room (6), a lamp (8) is arranged in the white lampshade (7), a drain valve (9) is arranged at the bottom of the shell body (1), a non-transparent cover body (10) is arranged at the position of an opening on the upper portion of the shell body (1), and is matched with the opening, and a plurality of observation windows (11) are arranged on the cover body (10). The aquatic animal illumination selection experimental system is simple in structure, exquisite in design, low in cost, prone to statistics of experimental results, good in repeatability, and beneficial for research standardization.
