Abstract

The invention relates to a feeding device for giant spiny frog and a feeding method thereof. The feeding device comprises a feeding box and a feeding platform, wherein the feeding box is placed on the feeding platform; the area of the bottom of the feeding box is smaller than the area of the upper bottom surface of the feeding platform; a circle of holes are formed at the bottom of the feeding box and are hollowly arranged. According to the invention, the fresh degree of flour weevil can be increased in the manner of changing the shape and structure of the feeding device. Meanwhile, the area of the bottom of the feeding box is smaller than the area of the upper bottom surface of the feeding platform, so that the bait can crawl and make a noise for attracting the giant spiny frog, the bait is prevented from dying after falling into water along the slope, the survival rate of the bait is increased, the giant spiny frog has more predation desire, the predation desire of the giant spiny frog and the fresh degree of the bait are promoted, the death rate of the bait is reduced and the cultivation efficiency of the giant spiny frog is further increased.
