The utility model relates to the field of aquaculture, in particular to an automatic efficient roe collecting device which comprises a spawning pond, an incubator, a first filter screen and a second filter screen. The bottom of the spawning pond is in an inverted cone shape; the diameters of the first filter screens are different, and the axes of the first filter screens coincide with the axis of the bottom of the spawning pond and are vertically arranged at the bottom of the spawning pond; the second filter screen is arranged at the water outlet; the diameter of filter holes of the first filter screen is two times larger than the diameter of roes. According to the automatic efficient roe collecting device, due to layer-by-layer filtering of the first filter screen, the filtering efficiency of the first filter screen is improved through the inverted-cone-shaped pool bottom, and impurities in water flow passing through the second filter screen are few; the second filter screen is not prone to being blocked, th
