The invention discloses a photostimulation carrying device for motion control of a carp robot. The photostimulation carrying device comprises a carrying board, a light shielding belt, a fin fixing belt, jumper boards, LED lamps with different wavelengths, and wires. The carrying plate is in the shape of a Chinese character 'Wang' that is cut from an all-purpose board. The light shielding belt is sewn to the carrying plate to form an arch bridge shape so as to adapt to a fish head portion. Two ends of the fin fixing belt are connected with two corners on the same side of the carrying plate. Thefin fixing belt forms double crosses on the same side. The jumper boards are inserted in pairs to each branch of the carrying board, and are symmetrically distributed inside and outside the light shielding belt. The LED lamps with the different wavelengths can be inserted to the jumper boards as required, and are divided into inner LED lamps and outer LED lamps. The inner LED lamps and the outerLED lamps in the same branch are connected in series, and the LED lamps in each branch are connected in parallel. The inner LED lamps stimulate eyes of carps internally, and the outer LED lamps serveas reminders externally. The photostimulation carrying device mainly solves the problem that light control experiments can only be operated in the dark or without light.
